Welcome to the summer edition of Energy Matters!
Once again, this issue is packed with industry-leading insights on how we can make our homes and buildings more energy efficient.
After one of the longest delivery phases we’ve experienced, RdSAP10 has finally arrived. It marks the first major update to the methodology in over a decade; an update that was long overdue. The previous version, while serviceable, limited what we could all achieve. As with any significant change, there will be challenges: practices will evolve, issues will emerge, and solutions (whether fixes or guidance) will follow. This is a monumental shift, and at Elmhurst, we’ve consistently advocated for energy assessors to be fairly compensated for the increased quality and time required on site. The value of the work you do has never been higher. We’re proud to offer the largest support team in the industry to help our members navigate this transition, something we’ve always taken great pride in.
The Future Homes Standard is also on the horizon, capping off another decade-long journey toward delivering world-leading, energy-efficient new build homes. While headlines have focused on the inclusion of solar panels, the real story is broader. These homes will be low-carbon and energy-efficient across the board, from fabric and heating to hot water, lighting, and renewables.
We recently held another excellent Scottish Conference, where the quality of debate and discussion was, as always, first class. With fantastic speakers, including an opening by a government minister, alongside officials and leading industry professionals, the event covered a wide range of vital topics. We’re now looking forward to our Wales Conference in September, and Northern Ireland later in the yearwe hope to see you there!
In other news, the legacy of Grenfell remains ever-present. A recent documentary has cast a stark light on the construction and renovation sector. The new Labour Government has just announced that the Building Safety Regulator will move out of the HSE and become an arm’s-length body from MHCLG. This single regulator will have a significant impact on building regulations and construction products. We’re watching developments closely and continue to work with MHCLG, DESNZ, and the BSR on all matters related to energy efficiency policy and regulation.
From our Scottish Conference, it’s clear that all devolved regions are preparing for change; whether that’s through EPC reform, new methodologies, the Future Homes Standard, or Scotland’s own Passivhaus-equivalent approach.
Now more than ever, independent advice and guidance from Elmhurst is essential. For over 30 years, we’ve remained impartial, unbiased by
technologies, products, or fuel types. Our focus has always been on accurate measurement, carried out by competent professionals. This commitment has built a qualityassured infrastructure that enables building owners and landlords to make informed decisions on air testing, ventilation, overheating, energy use, retrofit options, and much more.
Finally, I want to extend a heartfelt thank you to our Chairman, Stephen O’Hara, who recently stepped down after 26 years at Elmhurst. He assures us he’s not retiring, just focusing on new ventures that will no doubt keep him busy! Stephen joined when the company had just four employees and has guided us through the transition from voluntary energy assessment to a highly regulated industry. His legacy is one of integrity, resilience, and vision - values that the entire Elmhurst team will continue to uphold on behalf of our exceptional members.
I hope you enjoy this edition of Energy Matters, and that you and your families have a wonderful summer.
Warm Regards,
Stuart Fairlie, Managing Director, Elmhurst Energy

Planning for a Hotter future: The Importance of Overheating Assessments for New Build and Retrofitted Dwellings
In recent weeks, the UK has faced yet another spell of intense heat, with temperatures soaring well above seasonal norms. These events, which are becoming increasingly common, highlight a growing challenge for the built environment: our homes are not designed to cope with prolonged periods of extreme heat. As climate change continues to fuel hotter summers and more frequent heatwaves, it’s essential that we futureproof our housing stock, both new and existing, against the risk of overheating.
Why Are Our Homes Overheating?
The rise in overheating in homes is primarily driven by climate change, which is increasing average temperatures and making extreme heat events more frequent across the UK. However, these impacts are further exacerbated by poor building design and daily household activities.
Overheating is especially problematic in retrofitted dwellings. While energy efficiency measures are implemented to enhance thermal comfort during winter, these improvements can inadvertently reduce a building’s ability to dissipate heat in the summer months, increasing the risk of overheating.
The risks of Overheating
Overheating is more than an inconvenience - it’s a health risk. Prolonged exposure to high indoor
temperatures can lead to heat stress, disrupted sleep, and serious health conditions such as cardiovascular and respiratory issues. Vulnerable groups, including the elderly, children, pregnant women, and those with pre-existing conditions, are particularly at risk.
Smarter Solutions for a Hotter Future: Regulations to Address overheating
In response, the UK government introduced Approved Document O in 2022, mandating overheating risk assessments for all new residential buildings in England and Wales. The regulation focuses on limiting solar gains and promoting effective ventilation. Many new dwellings now reaching completion have been designed with these standards in mind which is a positive step forward.
In the retrofit world the focus has also rightly shifted to overheating in existing homes where the PAS 2035:2023 standard stipulates that:
“The retrofit design shall include measures to inhibit overheating of the dwelling during the installed life of the EEMs.”
Approved Document O outlines two routes for overheating assessment: the Simplified Method and the more detailed Dynamic Thermal Modelling. The latter allows for
a comprehensive analysis and is especially useful in complex or urban projects. Both methods can be adapted for new builds and retrofit scenarios.
Mitigation strategies may include external shading devices, low g-value glazing, improved cross-ventilation, and the use of passive cooling techniques. However, successful planning and implementation requires the expertise of qualified professionals.
Qualified Professionals Matter
As demand for overheating assessments grows, so does the need for competent assessors. Elmhurst Energy ensure that professionals who are members of their overheating scheme are suitability trained to competently complete these assessments.
In a warming world, staying cool at home is no longer a luxury… it’s a necessity.

Future Homes Standard, HEM
and SAP 10.3 set to Redefine
Compliance for New Builds
With the Future Homes Standard (FHS) set for release in Autumn 2025, major updates to Building Regulations will change how new homes are designed, assessed, and built. The new Home Energy Model (HEM) will sit alongside an updated SAP 10.3 in a dual compliance approach, and Elmhurst is actively supporting members through training, software updates, and expert guidance.
What is the Future Homes Standard?
The Future Homes Standard (FHS) is the name for the next revision to Part L of the Building Regulations in England. This will be a significant change to how new homes are constructed and the main aim is to ensure new homes will have low to zero operational carbon emissions.
The Future Homes Standard was first consulted on in 2019, with Part L 2021 being introduced as an interim step towards it. In 2023 a further consultation was launched giving more specific details on the
changes expected. The Government has stated they will publish the consultation responses and new Approved Document in Autumn this year.
What is the Home Energy Model?
Announced by government in December 2023, the Home Energy Model is a calculation methodology designed to assess the energy performance of homes across the United Kingdom. The model is designed to replace the current methodology used by the government; the Standard Assessment Procedure (SAP) but a date for this transition has not yet been confirmed.
The Home Energy Model will replace SAP by introducing a more advanced, modular, and future-proof methodology, which will include:
• Half-hourly simulations for more realistic modelling
• A flexible architecture for greater ease of use and continuous improvement
• A system based on International Standards
• An open-source methodology for complete transparencychanges to the model will be visible before they are formally implemented
• Cloud-based delivery model with a rebuilt Product Characteristics Database (PCDB)
Crucially, the model will use “wrappers” – such as an Energy Performance Certificate (EPC) Wrapper and Future Homes Standard (FHS) Wrapper - to tailor the tool to different use cases, ensuring clear separation and standardised inputs/ outputs across various applications.
The Home Energy Model will allow government to modernise from a system originally built for paperbased assessments, to a futureready methodology that better supports evolving policy, research, and industry needs - especially for recognising ‘net zero ready’ buildings.
for Future Homes Standard Compliance
In a statement issued in May 2025 the government announced that the Future Homes Standard will use both SAP 10.3 and the Home Energy Model (with the Future Homes Standard wrapper) to calculate the metrics used to determine compliance.
When the Future Homes Standard consultation launched in 2023, it was expected that the Home Energy Model would be the sole compliance tool. However following feedback from industry, the government has opted to allow a new updated SAP 10.3 version to be used as an interim methodology. It will feature a new notional dwelling, updated carbon and primary energy factors, and refinements to the current SAP 10 to support compliance with the Future Homes Standard. By continuing to use the well-established SAP 10 alongside the gradual rollout of HEM, the government aims to ensure a smoother shift once HEM and its supporting systems are fully ready.
the introduction of the Future Homes Standard?
With the expected publication of the Future Homes Standard in Autumn 2025, here’s look at what key changes we can expect.
1. Gas boilers will no longer be able to provide heating in new homes. The Future Homes Standard will require low/zero carbon heating systems to be used, expected to be heat pumps in the majority of cases.
2. Mandatory solar photovoltaic (PV) panels. The government has confirmed that Building Regulations will soon mandate the installation of solar PV panels on new homes for the first time. This requirement will likely take the form of a new functional standard setting a minimum solar provision, with flexibility allowed in exceptional cases, such as homes heavily shaded by trees or other obstructions.
3. Sunsetting of older transitional arrangements. In order to build as many new homes to the Future
Homes Standard it is expected transitional arrangements for sites under Part L 2006, 2010 and 2013 will be closed.
4. The use of regional weather data. Unlike previous versions of Part L which used UK average weather data, the Future Homes Standard will assess homes using regional weather data meaning compliance metrics will vary based on the home’s location.
What are Elmhurst doing to prepare for the Future Homes Standard?
As with previous changes to Building Regulations Elmhurst will ensure members are fully prepared for the new standards. We have recently commenced our HEM Theory CPD courses giving attendees an insight into the background of HEM and what changes this is likely to bring when it is introduced. Additional training is planned for SAP 10.3 and the Future Homes Standard.
Elmhurst have begun development of our HEM application for use with assessing compliance to the Future Homes Standard. Additionally, we will also be updating our Design SAP 10 application to incorporate SAP 10.3 so users will be able to use both methodologies to demonstrate compliance.
Jason Hewins, New Build Dwellings Manager, comments:
“We welcome the confirmation of the Future Homes Standard for Autumn 2025, marking a major shift in how new homes are assessed and built. The introduction of a dual methodology using SAP 10.3 and the Home Energy Model represents a balanced transition, and we’re committed to ensuring members are fully prepared. Development of our HEM and updated Design SAP 10 applications is well underway, alongside a growing programme of CPD and training. As soon as further details are confirmed, we’ll keep members fully informed.”

Scotland sets sights on greener homes with uplifted Minimum Energy Efficiency Standards (MEES) for Private Rentals
In a bold move to tackle climate change and fuel poverty, the Scottish Government has unveiled a draft regulation that could transform the energy performance of private rented homes across Scotland. The proposed Minimum Energy Efficiency Standards (MEES), now open for public consultation, aim to ensure that all domestic private rented properties meet a minimum energy efficiency threshold of EPC rating C by 2028, creating greener, warmer, and more affordable homes.
A Step Toward Net Zero
The draft regulations, published on 6th June 2025, are part of Scotland’s broader commitment to achieving net-zero greenhouse gas emissions by 2045. The private rented sector (PRS), which accounts for approximately 14% of Scotland’s housing stock, has long fallen behind other areas in energy performance. The MEES proposal seeks to close that gap by requiring landlords to upgrade the energy efficiency of their properties.
Under the proposed rules, all privately rented homes would need to achieve a minimum Energy Performance Certificate (EPC) rating of C by 2028, with interim milestones starting in 2026. The regulations would apply at the point of new tenancy from 2026 and then to all tenancies by 2028.
Why It Matters
The Scottish Government estimates that the Private Rented Sector contributes around 5% of the country’s total greenhouse gas emissions. Many of these homes are older, poorly insulated, and expensive to heat, placing a disproportionate burden on lowincome tenants.
The MEES proposal is also seen as a key tool in addressing fuel poverty, which affects nearly one in three Scottish households. By improving insulation and heating systems, the government hopes to reduce the number of tenants forced to choose between heating and eating during the winter months.
What Landlords Need to Know
The draft regulations outline a phased approach:
From April 2026: All new tenancies must meet EPC C.
From April 2028: All existing tenancies must meet EPC C.
Exemptions: Properties that are technically impractical or where improvements would cost more than a set cap may be eligible for exemptions. This is looking likely to be set at £10,000 (lower than the £15,000 cost cap proposed in England and Wales).
To support landlords, the government is proposing a package of financial assistance, including low-interest loans and targeted grants. However, concerns remain about the cost and viability of upgrades, particularly for older tenement buildings and rural properties.
Local authorities will be responsible for monitoring and enforcing the new MEES regulations. Using data from the EPC register and PRS property lists to check compliance. Penalties for non- compliance could range from £600 to £3,000 depending on the breach.
The benefits for tenants and the wider industry
For tenants, the benefits could be crucial. Warmer homes mean lower energy bills, better health outcomes, and improved quality of life. The regulations are also expected to stimulate the green economy, creating jobs in retrofitting, insulation, and renewable heating technologies.
EPC Reform
Scottish Government are also working on reforming EPC’s so that they have a clearer focus, concentrating on the building fabric, how well a property retains heat and giving better information on the emissions and efficiency of a property’s heating system. EPC reform will introduce a new rating, the Heat retention Rating (HHR) which will be used as the basis for MEES in the private rental sector. The existing cost-based rating will also remain allowing the EPC to continue to support fuel poverty policy.
The new EPC will provide three headline ratings:
1. Heat retention Rating (HHR)
2. Energy cost Rating (ECR)
3. Heating system Rating (HSR)
Scottish Government have set out that a Band C in the HRR will be broadly in line with the fabric performance of homes in Band C of the current cost-based rating.
Consultation Now Open
The Scottish Government is inviting feedback from landlords, tenants, local authorities, and industry professionals through a public consultation running until August 29, 2025. The consultation seeks views on the proposed timelines, cost caps, enforcement mechanisms, and support schemes. Stakeholders can respond online via the Scottish Government’s consultation hub or attend one of several regional engagement events planned over the summer.
Looking Ahead
If implemented, the MEES regulations will mark a significant shift in Scotland’s housing policy, placing energy efficiency at the heart of rental standards. While challenges remain, particularly around funding and enforcement, the direction of travel is clear: Scotland is committed to building a greener, fairer housing system for all.

Government Proposes MEES Framework for the Social Rented Sector in England
The government has released a proposal to introduce a minimum energy efficiency standard (MEES) for socially rented homes in England, as part of an effort to make these properties easier to heat, tackle fuel poverty, and reduce carbon emissions.
Socially rented homes are not currently required to meet a minimum EPC standard, and according to the government, current requirements are roughly equivalent to an EPC ‘F’ rating. The government’s preferred outcome of this consultation is to set a new standard for social landlords to get to EPC C or equivalent by 1st April 2030. This aligns with what has already been proposed within the domestic private rented sector.
What is Being Proposed Use of new EPC Metrics
Wider reforms to EPCs have already been consulted on, with new primary metrics proposed and responses under review by government. The proposed introduction of Fabric Performance, Heating System, Smart Readiness and Energy Cost as primary metrics signals a move away from the single Energy Efficiency Rating (EER) currently displayed on EPCs as an A to G Rating.
With regards to MEES for the social rented homes, the government proposes using one or a combination of the first three metrics (fabric, heating system, and smart readiness), rather than relying on a cost-based metric. The preferred option is for homes to meet a standard for fabric performance (the thermal performance of a building’s envelope) and a second standard
for either heating system or smart readiness by 2030.
Once again, this aligns with what has been proposed for reforms to Domestic MEES in the private rented sector.
“Focusing on fabric measures will improve the thermal comfort and overall decency of homes, reducing energy bills for tenants and reducing incidences of damp and mould. In practice, this means that providers would be required to prioritise investment in measures such as loft insulation, to achieve a fabric standard of EPC C.”
Part of the Decent Homes Standard (DHS)
The proposed MEES would form part of a reformed Decent Homes Standard (DHS), which is also open for consultation and expected to be introduced in either 2035 or 2037. It is intended that the new energy efficiency requirement would align with Criterion D –Thermal Comfort of the updated DHS.
If adopted, regulation would fall under the Regulator of Social Housing (RSH) , rather than local authorities, which are responsible for enforcement of MEES in the private rented sector.
Exemptions
The government is considering a range of targeted exemptions, some of which are already part of the existing DHS and may be retained or adapted.
These include situations where tenants refuse access for improvement works (with strengthened guidance on landlord responsibilities), cases
where physical or planning constraints such as those affecting listed buildings-make upgrades impractical, and properties that are due to be sold, demolished or regenerated. In each case, providers would be expected to demonstrate that they have taken all reasonable steps before relying on an exemption.
In addition, a new time-limited spend exemption is being proposed specifically for MEES. This would allow landlords to classify a property as compliant if they have spent up to a proposed limit of £10,000 per property on qualifying energy efficiency improvements, even if the property still falls short of the standard. All relevant spending, including grant-funded work, would count towards the exemption, and costs incurred from the date of the government’s formal response to the consultation would be eligible.
The exemption would last for ten years from the MEES compliance deadline of 1st April 2030, after which landlords would be expected to complete any outstanding work to bring the property up to
standard. The government believes this approach supports the core aims of reducing fuel poverty and carbon emissions, while allowing social landlords to manage competing demands on resources, such as delivering new housing and maintaining existing stock.
Elmhurst’s Thoughts
Elmhurst’s Managing Director, Stuart Fairlie, has welcomed the alignment between proposals for the social rented sector (SRS) and the private rented sector (PRS), praising the government’s effort to create a more consistent and strategic approach to improving housing energy performance across tenures:
“We are pleased to see joined-up thinking and strong alignment between what’s being proposed for social housing and what we have seen proposed for the private rented sector. A consistent framework for assessing and improving energy efficiency, especially through the proposed adoption of new EPC metrics, is a smart and strategic move that gives clarity to housing providers, assessors and the wider industry.
While there are currently no minimum energy efficiency requirements in the social rented sector, many providers have already made significant progress, with a large proportion of homes now achieving EPC band C or above. Establishing MEES for social landlords will help to build on that momentum, providing the certainty needed for long-term investment in both existing homes and new developments.
As ever Elmhurst will be developing its own response to this consultation with valued input from Members.”
The consultation for Improving the Energy Efficiency of Socially Rented Homes in England, is open until 10th September 2025.

Retrofit Done Right: A closer look at what “Good Retrofitting” means
Decarbonisation of the UK’s existing housing stock is a monumental challenge facing the Government and the Retrofit industry. A significant proportion of homes were built before modern energy efficiency and health and well-being factors were part of the standard building criteria. But what exactly does “good retrofitting” entail in the UK context?
The task at hand is more than just ‘bolting’ on Energy Efficiency Measures (EEMs), such as insulation or new technologies, and is more about looking at the property as a whole and how it can be improved over time. PAS 2035 introduced the Medium Term Plan to encourage a planned improvement of the property over time, and for the interaction of measures to be considered, including crucial aspects like airtightness testing, ventilation, and the often-overlooked issue of overheating.
A Fabric First Approach
At the heart of any good retrofit, where practical, the fabric of the property should be considered first. This ensures that the envelope of the property is robust, and as efficient as possible before other factors are considered. Simply put, if the fabric is efficient, the demands on heating the property will be reduced and investment on such systems (e.g. a heat pumps or new boilers) can be managed correctly.
Key elements of this include the correct and continuous insulation of the walls, floor and roof to avoid thermal bridging, windows and doors with higher performance units that can provide long-term durability and be maintained easily, and draft-
proofing. Often underestimated, effective draught-proofing is vital, and can be a particular issue in older properties where other works have been undertaken leaving air leakage pathways through the thermal barrier.
The importance of Airtightness testing
A cornerstone to determining where air leakage occurs and improving draft-proofing is airtightness testing. Through the use of blower door or pulse testing, the specialist can identify those areas of leakage, and aid in targeted repairs to prevent unintended air movement. Common issues include, electrical sockets, pipe penetrations, loft hatches and many more.
An airtightness test can thus be used to determine the scale of the problem in the first instance, and on completion of works, the improvement achieved through all measures taken to improve the fabric of the property, and thus the thermal efficiency.
Good practice then allows the Retrofit Coordinator to use an established methodology to determine pre and post gains, such as SAP or RdSAP. However, all the above must take into consideration the heritage of the property before being actioned and should not be forgotten when undertaking any works.
Don’t forget ventilation! Often sidelined, ventilation is an essential counterpart to airtightness and an essential part of good retrofit. While preventing unintended air leakage in a building is vital, a robust and well-designed ventilation
system becomes a fundamental requirement.
Probably the most well-known issue in older or badly ventilated properties is condensation and mould; the result of increasing moisture levels in airtight properties. This allows for the perfect conditions for mould growth, a concern not only to the fabric of the building but the health of those living within.
But there are other factors to consider in relation to good ventilation and the health of those living in the property, in the form of pollutants in the air. Our everyday activities such as purchasing new furnishings, and the retrofit works themselves, can lead to the release of pollutants in the air. In a poorly ventilated property these pollutants can accumulate, potentially resulting in health problems (e.g., respiratory issues, allergies), discomfort, and unpleasant odours.
An effective ventilation strategy should, at a minimum, comply with Building Regulations Part F and aim to minimise uncontrolled infiltration in favour of controlled, purposeful airflow.
The details of an effective ventilation system will depend on the characteristics of the property, but will often include mechanical extract ventilation (MEV) fans. These remove stale, moist air from ‘wet’ rooms such as kitchens and bathrooms, exhausting it outside, while fresh air enters through trickle vents or other controlled inlets. MEV fans should not be manually operated; instead, they should respond automatically to moisture levels in the air and continue running until those levels return to normal.
Regardless of the system chosen, it must be correctly sized, installed, commissioned, and balanced. It is also extremely important that the occupants are given clear guidance on how to use and maintain the ventilation system to ensure its effectiveness.
Overheating
With the increase in hot UK summers, and as homes become better insulated and more airtight, the risk associated with overheating increases and must be addressed to ensure that the health and wellbeing of the occupier is maintained, and all good retrofits must take this into account.
Best practice guidance recommends that overheating be assessed using Approved Document O and CIBSE TM59, both of which provide indepth methodologies for evaluating thermal performance and identifying potential problems.
However, unlike new build projects where designs can be optimised from the start, retrofitting involves working with existing structures, often with constraints that make traditional solutions less suitable. This means retrofit designers and coordinators must use innovative approaches to control overheating, such as installing external/internal shading solutions (e.g. shutters, brise-soleil, blinds), however external shading is generally more effective.
Other options include using low g-value glazing to reduce solar heat gain or incorporating louvred windows to enhance ventilation. Ultimately, this ties back to having the right ventilation system in place, which plays a key role in removing excess heat from the property.
In conclusion, while the energy efficiency of a property is important, good retrofitting goes well beyond that. It must also take into account occupant comfort, such as thermal performance and healthy indoor conditions like good air quality, while actively tackling the risk of overheating. By embracing these principles, along with others discussed in this article, we can deliver retrofit projects that are not only energy efficient but genuinely fit for purpose.
Steve Marriott Retrofit Scheme Manager
Could Ventilation Testing be the next step in your Retrofit career?
As the UK continues its push toward energy efficient housing, ventilation has emerged as a vital element in the retrofit process under PAS 2035. Recent updates to PAS 2035 not only reinforce its role in ensuring healthy indoor environments but also present a valuable opportunity for professionals to enhance their skills and stand out in a competitive market.
A New Priority in Retrofit
Proper ventilation in dwellings is essential for maintaining healthy living environments, preventing damp and mould, and ensuring occupant comfort. In retrofit projects, especially those involving insulation upgrades, ventilation must be carefully assessed and, if necessary, improved to avoid unintended consequences.
Key Changes in PAS 2035
Recent updates to PAS 2035 have introduced clearer expectations around ventilation assessment and documentation. These include:
• Detailed recording of background ventilation, such as trickle vents.
• Mandatory flow rate identification or testing of extract ventilation.
• Completion of the D1 Ventilation Checklist, including ventilation category and strategy.
• Disallowing passive stack and positive input ventilation systems.
• Pre-and post-air leakage testing for major insulation works.
Acceptable ventilation strategies now vary by measure category. For Category B, options include
IEV with correctly sized extractors and background ventilators. For Category C, continuous mechanical extract ventilation (MEV) or mechanical ventilation with heat recovery (MVHR) systems are preferred.
These changes create a clear need for competent testers who can assess both existing and new systems with accuracy and confidence.
An Opportunity to Build Competency and Add Value
As ventilation becomes a more prominent part of the retrofit process, testing both existing and newly installed systems is increasingly recommended. Accurate flow rate testing, typically carried out using anemometers, should be performed by individuals (sometimes known as Ventilation Tester) who have the appropriate training and understanding of current standards.
Elmhurst supports this by offering a two-day training course covering Part F and the Domestic Ventilation Compliance Guide, with successful participants eligible to join Elmhurst’s Ventilation Competency Scheme. While participation and test lodgement are not yet mandatory, doing so helps maintain high standards, offers reassurance to clients, and prepares professionals for any future requirements under schemes like TrustMark.
Ventilation is no longer a secondary consideration in retrofit projects but is a cornerstone of creating energy efficient, healthy homes. With the right training and testing practices, professionals can ensure compliance, performance, and occupant wellbeing.

PAS 2038 lays the groundwork for the future of Non-Domestic Retrofit
Since its publication in 2021, PAS 2038:2021, the British Standards Institution’s specification for nondomestic retrofit projects, has laid the foundation for improving the energy efficiency of commercial and public buildings across the UK. Over three years on, it’s gaining traction as the go-to standard for non-domestic retrofit, although adoption is still in its early stages.
What does PAS 2038 cover?
PAS 2038 introduces a structured, whole-building approach to retrofitting non-domestic properties such as offices, schools, retail spaces, workshops, and communal areas in multi-residential buildings. It ensures a comprehensive retrofit process that evaluates not just fabric and systems, but also indoor air quality, occupant comfort, and operational performance. For smaller commercial buildings under 500m² that operate with domestic-style systems, PAS 2035 may still be appropriate.
Uptake & Market Momentum
Unlike PAS 2035, which has seen widespread adoption in the domestic retrofit sector, PAS 2038 is still building momentum. However, as the UK steps up its decarbonisation commitments, uptake is expected to grow, particularly where public funding is tied to compliance. Government-backed schemes are increasingly aligning funding criteria with PAS 2038 standards, although formal compliance is not yet widely mandated.
This policy and funding landscape is prompting greater awareness and engagement across the nondomestic sector, as building owners, occupants, and energy professionals recognise the strategic advantage of early compliance.
Roles and Professional Opportunities
The delivery of PAS 2038 projects centres around two key roles: the Lead Professional (similar to the Retrofit Coordinator under PAS 2035) and the Lead Assessor. These roles must be filled by suitably qualified Non-Domestic Energy Assessors (NDEAs) or Display Energy Certificate (DEC) Assessors. This creates new opportunities for NDEAs and Retrofit Professionals to expand into the non-domestic retrofit market.
What’s Next?
As net-zero policies tighten, PAS 2038 compliance is set to become a standard requirement rather than a choice.
Expanded training opportunities will be available for NDEAs, DEC Assessors, and Retrofit Coordinators to address growing capacity needs.
A growing number of funding schemes are expected to link financial support directly to PAS 2038 compliance.
Greater regulatory clarity I expected on lifecycle carbon assessment, indoor air quality, and smart building integration.
PAS 2038 has established a strong foundation for high-quality retrofits in non-domestic buildings, with adoption steadily increasing. Early adopters, including qualified assessors, proactive building owners, and retrofit coordinators, are positioning themselves to meet rising demand.
As policy alignment and funding incentives continue to strengthen, PAS 2038 is well on track to becoming the core standard for nondomestic retrofit across England and Wales.
Elmhurst is gathering feedback on the current demand and interest in PAS 2038 and the retrofit of commercial buildings in England and Wales. If you are interested in learning more about PAS 2038, please take 5 minutes to complete our short survey.

Non-Domestic MEES Consultation outcome still pending as industry awaits clarity
The Government’s response to the long-awaited consultation on Minimum Energy Efficiency Standards (MEES) for Non-Domestic Buildings remains unpublished, despite being expected in the first half of 2025. As we eagerly await the official response, now potentially expected in Autumn 2025, Elmhurst take a closer look at why it’s so important for improving the energy efficiency of the non-domestic sector.
The History of Non-Domestic MEES
Since 1 April 2023, landlords of privately rented non-domestic buildings in England and Wales have been legally required to ensure that their building has an Energy Performance Certificate (EPC) rating of at least an E in order to let a non-domestic property. The initial 2019 consultation sought to ensure that privately rented nondomestic buildings in England and Wales would require an EPC B
rating to be legally let by 2030. This was followed by a white paper and further consultation issued in 2021, setting out proposals to ensure that enforcement was improved, and that policy could be delivered.
When was the official response expected?
The Government’s formal response to the MEES consultation was expected in the first half of 2025 but is yet to be published.
This outcome is crucial for shaping the path to the EPC B requirement by 2030 and for informing the design of future policy. MEES regulations play a key role in the Government’s wider efforts to enhance energy efficiency and reduce carbon emissions across the built environment.
When can we now expect the outcome?
Elmhurst has been assured that
the outcome and further details will be released in due course, with suggestions that this may come in the Autumn and align with the Warm Homes Plan as part of the spending review - though this has not yet been officially confirmed.
Elmhurst’s Consultation Response
Elmhurst strongly supports the proposed uplift in minimum EPC standards for non-domestic buildings in England and Wales. In our consultation response, we emphasised the need for a clear compliance trajectory aligned with rising standards, alongside improved enforcement and earlier compliance triggers – such as during property sales or lease renewals. We also highlighted the central role of non-domestic energy assessors in supporting MEES compliance and enhancing the energy performance of the built environment.
Elmhurst Thoughts
Danny Pearson, Non-Domestic Team Leader comments:
“MEES regulations play a crucial role in improving the energy efficiency of the commercial built environment in England and Wales, with NonDomestic Energy Assessors being at the forefront of providing advice to improve buildings. With the recent Domestic MEES announcement for both the private and social sectors, it is important that guidance for Non-Domestic MEES is also issued to align the future trajectory of both sectors and build momentum.
The release of MEES regulations will provide much needed clarity for both Non-Domestic Energy Assessors as well as the wider industry, whilst setting the future trajectory towards changes to minimum bandings and policy updates. Elmhurst will continue to advocate for both the important role
that Non-Domestic Energy Assessors play in improving the energy efficiency of existing buildings, and the importance of a clear trajectory for both assessors and the wider industry.
We remain at the forefront of driving the sector forward and hope to see an outcome to this consultation from Government as soon as possible, particularly in relation to policy changes and the upcoming 7-year payback review.”

Government Spending – A Year in Review: House Building, Warm Homes Plan, and Social Housing
On 4th July 2024, Labour replaced a Conservative government that had been in power for 14 years (five in coalition) and under five Prime Ministers. While much happened in that time, progress on building energy efficiency was limited. There were moments of support under Theresa May and Boris Johnson, policy rollbacks under Rishi Sunak, and a period under David Cameron where green measures were publicly downplayed. I may be missing someone… but that’s a topic for another time.
This legacy is estimated to have added over £22Bn to fuel bills, worsened by the cost-of-living crisis and global conflicts. Labour campaigned, some might say quietly, on tackling the climate emergency and getting the country back on track. So, 12 months on: what has Labour achieved, where are we now, and what’s been proposed?
EPC Reform and Domestic MEES: Consultations Underway
At the heart of this article lies the Energy Performance Certificate; now considered (admittedly by both this government and the previous administration) a critical tool for measuring and driving energy efficiency improvements. The government is currently midway through consultations on EPC reform and updates to the domestic Minimum Energy Efficiency Standards (MEES) in both England and Wales, with Scotland recently announcing its own consultation process. In fact, as I write this very article the government has just launched consultations on MEES for the social housing sector and a linked consultation on a new Decent Homes Standard, which also covers the private rental sector. It appears that, for the first time, the entire rental sector will be required to meet
the exact same standards. Quite the development.
Additionally, EPCs are expected to play a central role in determining eligibility for future Warm Homes Grant funding (more on that later) as well as supporting the move towards decarbonsied heating, hot water and smarter use of energy. Proposed changes include:
• Enhancing the accuracy and usability of EPCs.
• Introducing new metrics that better reflect real-world energy use.
• Reducing the validity period of EPCs to keep the information in them more up to date.
• Greater focus on quality; both in the EPC but also in training and continuous development of assessors.
House Building and Planning Reform Future Home Standard
The previous government began the process of introducing the Future Homes Standard; the next update to Part L of the building regulations. The first part was an interim step in 2022 and Labour has adopted the full implementation of the standards as consulted on. Whilst we don’t have confirmation of the all the details, this will be confirmed later this year with a new methodology being introduced at a later date to support it; the Home Energy Model.
The Home Energy Model is a more complex and detailed methodology which will increase the resolution of the calculation and allow for a growing number of wrappers to be produced for specific purposes, such as Future Homes Standard compliance. More recently, the government announced that SAP 10 would also be updated to version 10.3 as an interim measure to
provide soft landings during what is accepted as a period of great change.
House Building targets
In parallel, the government has also made strides in house building and planning reform. The Deputy Prime Minister announced that Labour would build 1.5 million new homes within this parliament. Key to this was freeing up planning pinch points and setting targets for local authorities to meet. This was ambitious a year ago and whilst we are starting see promising signs in the form of more property starts, the volumes are still far lower than needed to meet this target.
Related to this, the removal of planning barriers for heat pump installations has also been announced. This change is part of a broader strategy to streamline planning processes and accelerate the deployment of low-carbon technologies. The government has also pushed for a renewed focus on Solar PV technology; both in the Future Homes Standard, but also on existing dwellings and buildings with large roof coverings, like car parks.
Warm Homes Plan: Scaling Up for Impact
The government’s flagship Warm Homes Plan has seen significant development. The Warm Homes: Social Housing Fund, formerly known as the Social Housing Decarbonisation Fund (SHDF) launched in late 2024, and had an allocated £1.29 billion to improve the energy performance of social homes across England.
Despite speculation that there would be budget cuts to this funding, the government provided the Department for Energy Security and Net Zero (DESNZ) with further
support, bringing the total funding for the programme to £13.2 billion over the next 5 years. The plan is designed to tackle fuel poverty, reduce carbon emissions, and support the UK’s transition to cleaner heating technologies. We will know more about how the funding is broken down and how it will be targeted in the Autumn Spending Review.
This is both a welcome and necessary move, aimed at addressing the well-documented skills gap highlighted in numerous studies.
Rapid change but missing detail
So far, so good but none of this is finished. The big changes needed to support funding and regulation must land in the next 12–18 months, and right now, there are still lots of missing pieces. EPC reform, new methodologies, updated Minimum Standards and building regulations represent huge shifts for the built environment. They all need to be delivered well and in the right order.
But we still have no clarity on Non-Domestic MEES. No timescale, ratings, or response to the 2021 consultation. In that void, landlords and industry stakeholders are left in the dark and in some cases, assuming MEES will still be cancelled. Elmhurst have been assured that detail will come (if not the consultation response) as part of the Warm Homes Plan during the spending review in Autumn, and we will be holding the Government to account on this.
That said, the direction of travel is overwhelmingly positive and opportunities are opening up for energy assessors across the industry. For Elmhurst members, these changes highlight the need for accurate assessments, robust data and expert advice with the chance to lead the UK’s shift to energyefficient, future-ready buildings.

Beyond Box-Ticking: The Scientific Foundation of RdSAP and EPCs
The claim that EPC assessments amount to little more than a “box-ticking exercise” is a familiar one, frequently voiced by media commentators, property owners, and even some within the industry.
Much of this criticism is rooted in the assessments’ reliance on standardised data inputs, a direct consequence of the methodology behind them: the Reduced Data Standard Assessment Procedure (RdSAP).
However, Elmhurst recognises that RdSAP is far more than the sum of its parts…
The History RdSAP was created in 2005 as a simpler, lower-cost version of the UK’s Standard Assessment Procedure (SAP). Its development was driven by the need to implement the EU Energy Performance of Buildings Directive (EPBD), which required EPCs for all homes when sold or rented by 2007. At that time, SAP was already used for new-build compliance, but a ‘standardised’ practical method was needed for existing homes where detailed construction data might be unavailable.
Elmhurst Energy and National Energy Services (NES) (now Sava) worked with the Building Research Establishment (BRE) to merge their proprietary energy rating methodologies into what became RdSAP.
Since its launch in 2005, RdSAP has undergone a number of updates to refine its methodology and expand its capabilities, while staying aligned with the main SAP framework. These revisions typically introduced incremental improvements such as: updated default values, new options for inputs, and clarifications in conventions (assessment rules). The latest revision is of course RdSAP 10 which was released in June, and provided major improvements to the accuracy and robustness of the methodology.
The Science RdSAP is built on building physics
and is powered by decades of practical research into how buildings perform in practice. It draws on the same scientific principles as SAP, developed by the BRE to assess a home’s energy performance.
RdSAP is based on building physics and decades of research into how homes actually use energy. Like SAP (developed by the BRE), it uses building physics to determine a home’s energy performance by looking at heat loss, insulation, ventilation, and heating efficiency.
What sets RdSAP apart is that it is specifically designed to be used for existing homes. It uses a simplified set of data inputs, making assessments quicker and less intrusive. Instead of opening walls or floors, it uses science-based assumptions to estimate values where exact data isn’t available or cannot be directly observed.
During a standard site visit, assessors collect essential information such as the home’s age, type, floor area, and heating system. For elements that cannot be verified visually, RdSAP relies on two key tools: defaults and conventions, both underpinned by extensive technical research.
What are Defaults/Assumptions?
Defaults/Assumptions come from national housing surveys, BRE datasets, and construction-era standards. For instance, a property’s construction year is used to estimate its likely insulation levels and thermal performance. If you look at an EPC and it says ‘As-Built’ or ‘Unknown’ this is where a default/assumption has been applied.
What are Conventions?
Conventions guide Energy Assessors in how to consistently interpret and input data—such as how to treat inaccessible lofts or mixed construction types.
The Balance
The driving rationale behind RdSAP’s design is to balance usability with accuracy. For existing homes, it is often impractical or costly to collect every piece of data required for a full SAP calculation.
Many construction details can be hidden (within walls, floors, etc.), and homeowners may not have records of insulation or exact dimensions. Thus, RdSAP deliberately limits the required data to what a trained DEA can reasonably gather during a site visit. By reducing data needs, RdSAP has made nationwide EPC assessments feasible and affordable for virtually every home.
This efficiency, however, comes at the cost of some loss of accuracy or granularity. By using generic defaults, RdSAP can deviate from a dwelling’s true performance if that property is atypical. RdSAP does acknowledge this trade-off and is designed to keep results within acceptable margins. RdSAP’s results generally fall close to those of a full SAP calculation given the same property.
As mentioned previously, the assumptions/defaults used in RdSAP aren’t just guesswork and are in fact derived from decades of extensive research and modelling based on national housing data.
Final Thoughts
Elmhurst’s Managing Director, Stuart Fairlie, was at Elmhurst during the development and inception of RdSAP and its predecessors use for energy performance calculations back in the early 2000’s, and believes that some of the criticism comes from a lack of understanding of the methodology:
“From a homeowners perspective, it can be quite easy to overlook and criticise EPC assessments. Many will only see the output, the EPC itself, and don’t really understand the amount of work and building physics that has gone into creating that document.
However, the EPC is in fact generated from a combination of robust evidence collection, and decades of building physics/ research, brought together by accredited professionals who follow practical assessment conventions. This ensures that the energy performance of millions of homes across the UK can be measured and is workable at scale.
The fact that the software makes the life easier for an energy assessor is often misunderstood. Just one example of this in the data collection where the software asks a series of question about construction type, age of property, insulation, dry lining and wall thickness, which look up the derived U-value from ‘behind the scenes tables’ with decades of research, seems to be lost in the narrative.
This methodology is the baseline of a home’s energy performance, of course it can and should always be improved to keep up with prices, emissions and technologies; but it is now time for us all, as experts, to help use this baseline, to support informed decisions about whether or not to improve the home’s energy efficiency—and if so, how best to do it moving forward.”
Stuart Fairlie Managing Director
Mind the Skills Gap –The Installer Perspective
When the Labour Government was elected in July last year building new homes, developing a clean energy system and moving to net zero were among their key priorities.
They pledged to “Get Britain Building” with an aim of constructing 1.5 million new homes this Parliament, reversed the previous Government’s ban on creating new onshore wind farms, called for a “solar revolution” and made announcements on funding for installing heat pumps and other measures in its Warm Homes Plan. While many of these initiatives were welcomed by industry and stakeholders, including NAPIT who could see the benefits to our members, there have been concerns about whether there is a sufficiently skilled, experienced and qualified workforce ready to meet those challenges.
Thankfully Government, MPs and industry groups have started to highlight the fact that more needs to be done to avoid a skills gap which could hamper growth and decarbonisation plans.
A number of reports, consultations and surveys have been published helping to move the debate around the potential skills gap up the agenda:
The Government’s Industrial Strategy
The Government published its Industrial Strategy in June which aims to deliver the certainty and stability businesses need to invest in the high-growth sectors and drive long-term economic growth. The initial consultation included questions on skills and NAPIT responded highlighting areas where more needs to be done to encourage the existing workforce and new entrants into the sector to retrain and upskill to take advantage
of the opportunities available.
Heat Pump Association (HPA) Report
A good example of the number of workers needed in a single sector to ensure the UK meets its Net Zero targets was seen in a report published by the Heat Pump Association (HPA). NAPIT is a member of the HPA and fed into some of its findings.
The report highlights the sector is on track to train the future heat pump installation workforce needed to accelerate the deployment of heat pumps, but certainty and increased consumer demand are needed to encourage trained individuals to become active in the workforce.
It says that in order to meet the previous Government’s target of 600,000 heat pump installations a year by 2028, over 41,000 fulltime roles will be needed across the whole heat pump workforce, rising to 122,000 by 2035 to meet the target of 1.6 million heat pump installations per year.
Trustmark – The Big Conversation
A further survey was carried out by TrustMark as part of its Big Conversation. It asked its members – including NAPIT members – about the real-life challenges that trade businesses are experiencing in terms of recruiting and retaining skilled staff, including in the renewables and low carbon sector where skills shortages are projected to be particularly acute.
Workforce planning to deliver clean, secure energyConsultation
Another inquiry into workforce planning to deliver clean, secure energy was carried out by the House of Commons Energy Security and Net Zero Committee. NAPIT responded to the inquiry
consultation which asked whether Government has an appropriate understanding of the skill needs to deliver the Clean Energy Mission by 2030 as well as decarbonise homes and businesses.
It also sought views on whether the retrofitting of homes and businesses can be carried out by the existing workforce and to what extent will it require new entrants to the workforce.
Why a trained, competent workforce is essential to achieving housing and decarbonisation targets
Our view is that while the Government has taken significant steps there is still a considerable disconnect between policy ambition – plans to build 1.5m new homes and reach Net Zero - and how that will be achieved.
We highlighted that the UK’s commitment to achieve net zero greenhouse gas emissions by 2050 requires clear, coordinated targets and effective standards, particularly regarding decarbonisation within the housing sector, and sufficient competent and qualified tradespeople to carry out the work.
It is vital that there are sufficient experienced, trained, qualified and accredited tradespeople to carry out the necessary volume of installs and the expansion of housebuilding and associated installs along with a comprehensive retrofit programme will provide economic benefits to workers across the country.
However, if there is not a guaranteed pipeline of work, installers may not have an incentive to retrain or upskill. Without the availability of skilled workers across all trades, the building targets and those around
net zero are at further risk.
The current workforce is already playing a vital role in the transition. However, retrofitting of homes and businesses and moving away from fossil fuels to electrification, heat pumps, adding heat batteries, solar panels, battery storage systems or EV chargers will require a combination of upskilling existing workers and attracting new entrants to the workforce.
NAPIT will continue to highlight the opportunities to its members from the housebuilding and Net Zero agendas but also ensure Government is aware of the issues around skills and hears from those in our industry who are on the front line and most needed.

Existing Dwellings
Existing Dwellings Volume of EPC lodgements and residential house sales on a rolling 12-month basis (by quarter).
EPCs and House Sales
The latest data provides valuable insight into the evolving trends in EPC lodgements and house sales across the UK.
A notable surge in EPC lodgements occurred in the early years, peaking around mid-2014. This was followed by a steady decline until 2018. Since then, EPC activity has stabilised and shown a gradual upward trend, reflecting a more consistent demand for energy assessments. Most recently, May 2025 recorded 1.74m EPC lodgements (moving annual total), continuing this positive trajectory.
House sales have followed a more cyclical pattern. After a relatively stable period, the market saw a sharp rise in the early 2020s, peaking in mid-2021. While there was a subsequent decline, recent months have shown a renewed upward trend. In May 2025, there were 1.18m house sales (moving annual total), indicating a potential resurgence in buyer confidence and market activity.
The correlation between EPC lodgements and house sales remains evident. However, the data also highlights that EPC activity is influenced by more than just transactions - factors such as retrofit initiatives, landlord obligations, and energy performance regulations are playing an increasingly important role.
New Build / On Construction
New Build / On Construction Volume of residential house starts and completions on a rolling 12-month basis (by quarter).
Housing Supply Trends: Starts vs. Completions
The latest data on housing supply across England, Wales, Scotland, and Northern Ireland highlights key shifts in construction activity over the past decade.
Annual housing starts (blue line) and completions (red line) have both experienced notable fluctuations from December 2011 to March 2025. Starts peaked around 2019, followed by a sharp decline during the pandemic. While there has been some recovery since, the trend remains uneven.
Completions have generally followed a similar pattern, though with a time lag, reflecting the typical construction cycle. After a period of relative stability in the early 2020s, completions have shown signs of softening in the most recent data.
This divergence between starts and completions highlights ongoing challenges in the sector, including supply chain disruptions, labour shortages, and planning delays - all of which continue to impact the pace of new housing delivery.

New Build Energy Performance Certificates
The latest data on new build Energy Performance Certificates (EPCs) reveals a long-term upward trend from November 2013 through to mid-2020, reflecting a period of sustained growth in new housing delivery and energy assessment activity.
However, the graph also highlights a notable dip around 2020, linked to the disruption caused by the COVID-19 pandemic. While there was some recovery in the following years, the trend has since shown gradual decline through to May 2025.
This recent softening may point to a slowdown in new housing starts and completions or shifting regulatory and market conditions affecting the pace of new build developments.
Non-Domestic
Non-Domestic/Commercial buildings property sales and commercial property EPCs in the UK on a rolling 12-month basis.
Trends in Non-Domestic EPCs and Sales
The graph, which presents rolling 12-month totals, shows that the number of EPCs issued (blue line) has experienced notable fluctuations over the 12-year period. These peaks and troughs may reflect changes in energy efficiency regulations, market demand, or broader economic conditions influencing property upgrades and compliance.
In contrast, non-domestic property sales (red line) have remained comparatively steady, suggesting that while the drive for energy certification has varied, the underlying market for non-domestic property transactions has been more resilient.
The divergence between EPC issuance and sales indicate periods of increased regulatory enforcement or incentives for energy efficiency improvements, rather than direct market shifts, for example Minimum Energy Efficiency Requirements.
As the UK continues to push for greener buildings and tighter energy standards, these trends offer valuable insights into how policy and market forces intersect in the non-domestic property sector.
