Keltbray is a specialist construction engineering and major civils solutions group
Our purpose is to redefine the way sustainable development is delivered.
Based on our collective experience, we collaborate at the earliest stage to design and self-deliver innovative customer solutions across technically demanding built environment and major civils sectors. Working in partnership with our stakeholders, we are actively contributing to economic growth, social advancement and environmental protection.
Engineering a Better World
This year, our sustainability work continued to evolve, shaped by the practical challenges and opportunities we encountered across our projects. In this report we recognise successes, while also acknowledging that we remain early in our journey.
We know that the scale of the climate and sustainability challenges facing our sector requires long-term commitment and partnership. As PAS 2080 emphasises, real progress comes from shared responsibility, transparent decision making and a willingness to learn and adapt. These principles guide how we approach our work – not as a set of accomplishments, but as a continuous process of improvement.
Looking to 2026, we will carry forward the momentum built this year, but with a focus on maturing our approach, strengthening our evidence base, and directing our efforts where they can make the most meaningful difference. Sustainability remains central to our purpose, and we will continue to approach it with honesty and a commitment to doing better year on year.
Senior Leadership Insight
This year saw a broad range of meaningful activity across our sustainability programme. This report focuses on the positive steps we’ve taken over the past year – wins that are important to recognise because they reflect real effort, collaboration and progress across the business, of which we are very proud.
At the same time, we are clear-eyed about the fact that there is still a great deal to do. The challenges we face are not solved by isolated successes, but the momentum we’ve built gives us energy and direction. As we move into 2026, we’ll carry this positivity forward and continue to focus on tackling the hard problems with the same honesty, persistence and practical action that shaped our work in 2025.

Carbon
As well as working to reduce our own company carbon impacts, Keltbray also strives to deliver carbon reduction for our clients on their projects and influence the industry as a whole to improve.
Carbon Emissions
Climate change is one of the most pressing issues of our time; at Keltbray we recognise that our operations form part of the problem. Bold action is needed, which is why we have set net zero as our organisational goal.
In 2022, Keltbray signed up to the Science Based Targets Initiative, committing to reduce our emissions in line with the 1.5°C Paris Agreement.
We first calculated our baseline emissions in 2023 and selected 2019 as our baseline year, in line with best practice at that time and to support our commitment to achieving Net Zero by 2050, as required under Procurement Policy Note (PPN) 06/21
However, this historic baseline is no longer representative of our current organisational structure due to significant changes, divestments and dissolutions have resulted in a substantially smaller business, making previous emissions data unrepresentative of our current operations.
To ensure transparency, accuracy, and compliance with the technical standard for Carbon Reduction Plans, we have established a new baseline year of 2024. This is the earliest point at which we can feasibly separate our accounts and accurately reflect the emissions of our current business structure across Scope 1, Scope 2, and the required Scope 3 categories. We will verify our targets with SBTi in 2026.
In 2025, Keltbray continued working to reduce our emissions and develop our roadmap for long-term
decarbonisation beyond our 2030 target.
Following the achievement of the PAS2080 Carbon Management in Buildings and Infrastructure Accreditation in 2023, in 2025 Keltbray focussed on continuing to embed carbon reduction into our company processes and systems. At the end of 2023, the PAS2080 standard was updated to include an expanded scope. Over 2025, we worked to ensure our systems satisfied any new requirements.
Check out our Carbon Reduction Plan.

GAIA CARBON ACCOUNTING SOFTWARE
In 2025, Keltbray further improved our carbon management capabilities by investing in Gaia, a carbon accounting software platform used to measure, analyse, and report greenhouse gas emissions.
Gaia’s software aligns with the Greenhouse Gas Protocol and utilises trusted data sources such as the UK Government’s DEFRA emission factors to ensure accurate reporting.
The software automates our Scope 1, 2 and 3 emissions calculations using live data integrations and supplier information, reducing administrative workload and improving the
efficiency of our reporting. The platform generates compliance reports that can be used for SECR audits.
For Keltbray’s sustainability team, Gaia enables the consolidation of business-wide plant, fleet, material use and subcontractor data into a single platform, enhancing the consistency and transparency of company and project level carbon reporting. It’s analytics features help identify carbon hotspots and compare different projects - supporting both compliance and continuous operational improvement.

POWERING OUR SITES RESPONSIBLY
At Keltbray, connecting our projects to the electrical grid remains our primary strategy for reducing carbon emissions from construction power. In 2025, all but two of our sites were grid connected—an achievement made possible through early planning, strong client engagement, and innovative sequencing of works.
Where grid access isn’t immediately possible, we focus on minimising generator use and deploying the cleanest available alternatives, using hybrid systems, battery storage, alternative fuels and careful generator sizing to reduce emissions.
Several projects this year demonstrate how we navigate these challenges:
– King William Street: the team overcame space limitations of the constrained central London site by creatively reusing an existing low voltage connection and rephasing construction to bring permanent high voltage substations online early.
– Paddington Over Site Development: a mix of a low voltage connection, a small
generator and a battery storage module enabled works to proceed efficiently until the permanent substations could be built.
– Euston Tower: our early works strategy focused on installing the permanent high voltage infrastructure as soon as possible, reducing reliance on temporary power sources.
We continue to refine our approach to hybrid systems, particularly for Stage V generators, which perform most efficiently at higher loads. Larger battery packs and carefully selected generator sizes have helped reduce run times and improve fuel efficiency across several sites. Looking ahead, in 2025 with will explore the use of large battery systems—around 500 kW—to support cranes, hoists and pumps from relatively small grid connections. While this approach has not yet been deployed live, it shows significant promise as we look to further reduce generator use.
Overall, our focus on grid-first power, hybrid solutions and early planning continues to drive meaningful reductions in carbon emissions across our construction activities, even on the most complex and constrained sites.

LOWER-CARBON MATERIAL TRACKING AT 10 KING WILLIAM STREET
At 10 King William Street, we supported the client by developing detailed carbon forecasts for use within their Whole Life Carbon Assessment. We also provided integrated sustainability data to equip the sustainability consultant with reliable, project-specific information for producing accurate as-built carbon assessments. Throughout delivery, we tracked and adjusted concrete mix designs in line with real-time weather conditions, enabling the selection of more carbon-efficient mixes whenever conditions allowed.
Case study CONCRETE INDUSTRY COLLABORATION
As a company that purchases large volumes of concrete for our customers’ projects, we recognise our significant purchasing influence and the responsibility this brings to accelerate carbon reduction within the construction value chain.
In Spring 2025, Keltbray hosted supply chain sustainability workshops with our key concrete partners. We brought together senior representatives from Holcim, Tarmac, Heidelberg Materials and Cemex to openly discuss challenges, share innovation pathways, and identify opportunities
to accelerate the decarbonisation of concrete across our projects.
These sessions signalled our clear expectation that sustainability performance is a priority and reinforced the importance of collaborative action in driving down embodied carbon, improving resource efficiency and advancing lower carbon material solutions.
This proactive engagement marks an important step in aligning our supply chain with our longterm environmental objectives.

ELECTRIC
WHEELED
LOADER
– PLAISTOW
WHARF
Over the years, Keltbray’s plant department has established strong partnerships with leading manufacturers such as Caterpillar, Liu Gong, and Komatsu – relationships that have allowed us to collaborate closely in the industry’s shift towards electric machinery. By monitoring the performance of electric plant against diesel models, Keltbray can provide real-time data to manufacturers
In our Plaistow Wharf facility, Keltbray trialled Liu Gong’s 870HE electric wheeled loader, tested against its diesel counterpart.
The environmental benefits were clear: Emissions: 80% reduction in CO₂ emissions368 CO2e/kg versus 1,803 CO2e/kg for diesel.
Noise monitoring: the diesel loader was 6 to 9 dB louder than the electric model at low to mid frequencies. These frequencies travel further, penetrate barriers more easily, and are particularly noticeable to the human ear— making them a major contributor to noise pollution in surrounding areas.
Cost savings: operational costs were more than halved through the replacement of diesel with electricity
Operators also reported a quieter, more comfortable working environment with improved air quality thanks to the absence of exhaust fumes.
This trial demonstrates that electric loaders can deliver both environmental and financial benefits without compromising on performance, making them a strong candidate for future adoption.
Circular Economy
The construction industry is the world’s largest consumer of raw materials and generates a third of the world’s overall waste.
To combat this, Keltbray embraces Circular Economy practices; striving to reduce waste and resource extraction by looking at the buildings we demolish as potential assets for reuse, keeping materials in use for as long as possible, and prioritising recycling over disposal.
In 2025, Keltbray continued to collaborate with our clients, local authorities, engineers and developers to further understand how the material in buildings scheduled for demolition can be reused in the new development or in other projects across the industry.
Circular Economy
Case study
CIRCULAR
ECONOMY 55 OLD BROAD STREET
Keltbray’s circular economy achievements at 55 Old Broad Street demonstrate that high volume material reuse and closed loop recycling is deliverable at scale with early planning and collaboration with industry partnerships.
Landsec’s plans for the 55 Old Broad Street project set out ambitious low-carbon targets for the new development, aiming for high structural retention and material recovery. Through embracing circular economy practices, Keltbray was able to help the client stay on track to achieving these goals.
OUR CIRCULAR ECONOMY APPROACH
Early planning
Keltbray’s sustainability and site teams completed detailed pre-deconstruction audits on site pre-strip out, allowing us to compile data on all available material streams and identify best reuse and recycling routes. Through early preparation, Keltbray were able to properly plan for careful extraction and organise complex collection logistics before demolition commenced.
Collaboration with Reuse partners
On this project, Keltbray was proud to be one of the first participants in the City of London’s ROMULUS initiative with Maconda. We uploaded our material data to the initiative’s digital platform, which operates as a city-wide broker system between contractors and local stakeholders, connecting supply and demand for reused materials. In total, 40 sanitary units and 28 kitchenettes reused via ROMULUS to local schools, avoiding ~7.94 tonnes of CO₂e and generating approximately £14,000 of social value through the procurement savings for the schools.
Supplier Take Back Recycling Scheme:
Overall, 5.6 tonnes of carpet tiles were extracted and recovered for closed-loop recycling through Tarkett’s Restart programme.
Supplier Take Back Reuse Partnership: Working with the supplier RAF, 4,000m² of raised access flooring was removed, preserved and sent back to the RAF for reuse in other Landsec projects.
Closed-Loop Recycling: The site team worked closely with Saint Gobain’s glass removal guidance, allowing our team maintain the cullet quality thresholds necessary for remanufacture, preventing downcycling.
In total, 9.36 tonnes of glass was removed, saving approximately 11.23 tonnes of virgin raw materials and avoiding the release of 6.55 tonnes of CO2e.
Ironmongery: Working with Franchi ironmongery specialists, 500kg of high-quality ironmongery was recovered from site and sent away to be refurbished and redeployed back into the supply chain.
Our work on 55 Old Broad street demonstrates the viability of circularity in demolition and showcases how early planning, industry collaboration and responsible deconstruction can extend product lifecycles and accelerate the transition to a circular economy.

1 VICTORIA
At 1 Victoria Street, Keltbray was contracted by Stanhope to deliver the strip out, demolition and sub and superstructure construction package for a new development.
As part of the project’s targeting of ambitious sustainability targets, Keltbray embraced a circular economy approach to the significant amount of high-quality material left in the 10-storey former government headquarters of Business and Trade. Much of this activity started in 2024, but continued into 2025, as the final parts of the building were demolished and we moved into the construction phase
Keltbray’s sustainability team worked closely with the site team to implement the circular economy by diverting from landfill the large volume of reusable office material left behind by the previous tenant.
This circular economy initiative helped Keltbray deliver project carbon savings for the client by reducing the carbon emissions associated with material disposal and generating strong social value for the local community.
Globechain: Community Reuse at Scale
Globechain is a reuse marketplace, focussed on connecting businesses with nonprofits, small
organisations and individuals to redistribute unwanted items instead of sending them to landfill. Companies list surplus assets such as furniture, equipment, and fixtures on Globechain’s online platform for others to claim and reuse.
At 1 Victoria, Keltbray advertised items including office chairs, desks, hand dryers, cabinets, gym equipment and more on the Globechain platform, ensuring they were directed to charities and community organisations rather than recycling or landfill. This approach transformed what would traditionally be sent for recycling into social value, extending the lifespan of items and reducing material extraction associated with new manufacturing.
Keltbray’s team spent time extensively cataloguing items on site and listing them on Globechain to allow charities to register interest
with enough lead time for logistics.
WHAT WAS ACHIEVED IN 2025
– 124 items collected and redistributed to charities and local community groups, including YMCA and a local youth tennis group, and mental health support organisation among others
– ~2.397 tonnes of carbon emissions were not released through diverting the items from recycling or landfill
– 1,626 kg of waste avoided
– Significant cost savings for charities and community groups who would otherwise need to purchase equipment
– Generated goodwill within the local community that neighbours the large construction site by providing social value directly for neighbouring stakeholders

LADY MAYOR’S SHOW –SUSTAINABILITY GLOBE
In 2025, Keltbray were proud to once again take part in the world’s oldest civic procession – celebrating Dame Susan Langley’s upcoming 12 months as Lady Mayor.
In recognition of Keltbray commitment to embracing sustainability in the built environment, our float this year included a large globe made from recycled PPE material gathered from across our project sites. Our social value and sustainability team worked with the Construction Youth Trust and the local Westminster Grey Coat Hospital schoolchildren to design and build the globe.
Biodiversity
Keltbray seeks to understand, avoid and respond to any potential impacts its operational activities may have on biodiversity and sensitive ecosystems. Our projects and operations aim to minimise our impact on the environment to the greatest extent possible and we will collaborate and support our clients achieve biodiversity net gain, where applicable.
Biodiversity creation is often not in Keltbray’s scope of works, however we aim for exemplary protection of biodiversity on our sites. We also look for opportunities where we operate to make a positive contribution to conservation and to support local community-based environmental improvement projects.
Case Study
CHURCH STREET NESTING BIRDS
In May of 2025, a seagull nest was discovered on the roof of the Church Street development.
Keltbray site team worked with the project ecologist and the environmental team to implement the following procedure:
The seagulls successful fledged in July of 2025. Although nesting birds have the potential to cause significant delays to demolition work, the Keltbray team followed the regulatory guidelines and were able to deliver a successful outcome for the birds and ensure the project remained compliant with environmental law.
– The site team carried out daily inspections of the nest
– Heras fencing with Monarflex sheeting was installed across the area to create an
exclusion zone around the nest
– Additional Monarflex was affixed to the internal handrails of the external access scaffold to form a visual barrier, ensuring the seagulls could not see the workers on the roof
– Installation was carried out using non-noisy methods, such as hand tools instead of impact guns, to minimise disturbance
– Once the seagull chicks had hatched and were venturing out from the nesting area, the nest was removed by KES operatives following the HSE guidelines

HEATHROW VOLUNTEERING CLEARANCE DAY
In February of 2025, Keltbray volunteers spent the day at Bedfont Lakes Country Park, helping to clear scrub to enhance an overgrown clearing used by bats.
The Heathrow Project Volunteering Clearance Day provided an opportunity for Keltbray to actively contribute to biodiversity enhancement in the local area, supporting the client Costain’s development package and fostering positive environmental outcomes.
While direct implementation of Biodiversity Net Gain (BNG) targets was not feasible on the Heathrow development site, the team's participation in volunteering activities helped improve ecological value for the neighbouring area and demonstrated our commitment to responsible environmental stewardship.
Through collaborative engagement, Keltbray supported habitat management and clearance efforts, promoting the resilience of local wildlife and strengthening partnerships with stakeholders invested in sustainable development.

IN HOUSE ENVIRONMENTAL ACOUSTICS
Throughout 2025, Keltbray’s Sustainability team continued to enhance our Environmental Noise, Dust and Vibration (NDV) capability, investing in the development of our in-house service.
A significant milestone this year was the professional development of Kathy Johnston, Acoustics and Environmental Monitoring Specialist. Kathy successfully completed the Institute of Acoustics (IOA) Diploma in Acoustics and Noise Control and achieved Associate Membership of the IOA— qualifications typically associated with external acoustic consultants who prepare, review and endorse technical submissions. Bringing this level of expertise in-house enhances Keltbray’s technical capability, improves our efficiency in producing noise and vibration assessments, and increases our independence in managing NDV control measures across our project portfolio.
This investment has enabled us to deliver a more integrated and technically robust acoustic and environmental monitoring offering across our projects, reducing reliance on external consultants and improving responsiveness to project needs. By developing these skills internally, we are better positioned to plan, manage and evidence how noise and vibration impacts are controlled throughout each stage of the project lifecycle. This strengthens our ability to support compliant, responsible delivery while driving continuous improvement in our

DRIVING CIRCULARITY THROUGH INDUSTRY COLLABORATION
Throughout the year, Keltbray deepened its industry engagement by contributing to a broad range of forums and collaborative initiatives focused on decarbonisation, reuse and circularity. Keltbray sponsored two conferences, the Ground Engineering Sustainability event and the Biz Now Retrofit and Remodelling Conference. We contributed to the GPE Circular Economy Focus Group, the AC DG (Acceleration of Concrete Decarbonisation Group), the City of London’s ROMULUS initiative and ReLondon circular economy workshops. We also engaged with the wider built environment community through attendance at Footprint+, A Circular Revolution, the UCL Circular Economy Conference and the IStructE Climate Emergency Conference. In addition, Keltbray supported sector-wide knowledge sharing through two separate contributions to the Engineers Re Use Collective: Aisling Reynolds and Rob McCullogh provided a contractor’s perspective on practical reuse challenges and opportunities, while Rob—our Lead Engineer— also hosted a separate “No Silly Questions” session designed to build confidence, enhance understanding and encourage wider adoption of reuse practices across the industry. We further strengthened crosssector collaboration by hosting the Preservation, Planning & Progress: The Circular Economy in Action event with Stanhope and Westminster Business Council at our 1 Victoria Street site, bringing together industry leaders to explore circular economy innovations in complex redevelopment projects.

RETURNING TO TRIANGLE GARDENS
In 2024, Keltbray played a key role in one of our largest community investment projects, supporting Global Generation’s vision for Triangle Gardens in Camden, central London. This year, the company returned to the site to continue contributing to its development and to strengthen the partnership with the charity.
Global Generation is an environmental education charity that creates green spaces to bring communities together and inspire sustainable living. Triangle Gardens is their first permanent site, a space designed for educational and community activities, promoting biodiversity and environmental awareness.
Last year, Keltbray helped lay the foundations for three of
Triangle Gardens’ buildings. A team from our London Museum project relocated to the site for four weeks, carrying out enabling works, building concrete shutters, placing rebar, and finishing the slabs that would form the bases of the structures.
In 2025, we returned to see the progress and contribute once again. A 20-strong team spent the day supporting a range of activities. This team was made up of volunteers, mostly graduates from our programme and colleagues from our London and Essex offices. The volunteers split into groups and got to work crafting sweet chestnut roof shingles using traditional methods, dismantling a temporary structure to make way for new works, moving large logs for the eco hub, and even making clay bricks
for one of the new buildings, leaving a Keltbray imprint on the project.
Sustainability is central to Global Generation’s ethos and aligns closely with Keltbray’s values. By volunteering, Keltbray helped move the project forward, saved the charity money, and deepened our understanding of their mission. The day also served as an excellent team-building opportunity.
Feedback from volunteers was overwhelmingly positive, and everyone expressed enthusiasm for future opportunities.
Keltbray is proud to continue its partnership with Global Generation, reinforcing our commitment to sustainability, Social Value, and creating a lasting impact in the communities where we operate.

KELTBRAY AND THE ABBEY CENTRE –TEA PARTIES
Keltbray has a long-standing presence in Westminster, delivering major projects while building strong relationships with local community organisations. One such partnership is with The Abbey Centre, a well-established community hub dedicated to supporting South Westminster residents. In 2025, Keltbray worked alongside The Abbey Centre to help combat social isolation among older people through its Young at Heart Tea Parties.
Founded in 1948, The Abbey Centre’s mission is to foster a healthy, inclusive community by providing space, services, and opportunities for those who need them most. The charity champions social justice and works to improve
wellbeing for vulnerable residents, promoting togetherness and reducing isolation.
A key initiative is the Young at Heart programme, which offers social activities for people over 50 throughout the year. Many participants face challenges such as poor mental health and physical health issues, making these events vital for their quality of life.
Twice a year, The Abbey Centre hosts its Young at Heart Tea Parties: afternoons of sandwiches, cakes, conversation, music, dancing, and of course, tea. Keltbray, alongside Mace (our main contractor at the 1 Victoria Street project), part-funded both Tea Parties and provided enthusiastic volunteers to support the events.
Volunteering plays a crucial role in the success of these gatherings, ensuring guests feel welcome and valued. For some attendees, this may be their only conversation that day, week, or even month. By engaging with participants, volunteers help create a sense of belonging and community, tackling loneliness and social isolation head-on.
Keltbray is delighted to support The Abbey Centre and its mission to improve lives in Westminster. This partnership reflects our commitment to delivering social value and making a positive impact in the communities where we work.

OPEN DOORS 2025 AT FIFTY FENCHURCH STREET
At Fifty Fenchurch Street, future talent had the chance to step behind the hoardings as part of Build UK’s Open Doors initiative. In 2025, Keltbray once again welcomed students and local stakeholders to one of our most iconic projects, showcasing the diverse careers available in construction.
Open Doors takes visitors behind the scenes to experience live construction sites and learn about the roles that bring these projects to life. It is an opportunity to engage with young people, community partners, and stakeholders while promoting careers in the built environment.
Over two days, we hosted groups at Fifty Fenchurch Street, including students from London South Bank University, the University of Westminster, and local residents. Our Assistant Project Manager, Kevin Ramsey Jr, outlined the scope of the project, delivery methods, and the vision for this landmark development. Discussions highlighted the site’s heritage features, including the Grade I listed Church Tower of All Hallows Staining and the Grade II listed Lambe’s Chapel Crypt. Visitors then donned PPE and toured the site. They observed machinery in action, stood on the temporary platform enabling
works, viewed historic graves excavated by the Museum of London Archaeology, and saw the Church Tower’s support structure. Project Manager Harvey White led the tour, answering questions on underpinning and the plunge column system protecting the listed structures.
The day concluded with an interactive session, where a Graduate Engineer shared her route into construction, our Early Careers specialist outlined pathways into the industry, and our Social Value team explained how the Fifty Fenchurch development supports local employment and community investment.
Across the two days, 20 visitors gained valuable insight into live construction and career opportunities in our sector. We also supported our main contractor, Mace Dragados, by presenting at HS2’s Curzon Street site in Birmingham to college students on ground engineering.
Open Doors plays a vital role in attracting new talent and inspiring those already studying construction. Keltbray continues to champion this initiative, highlighting the exciting career opportunities our industry offers.

COMMUNITY INVESTMENT DONATIONS
In 2025, Keltbray continued to support local charities and community organisations through donations, materials, and services. This year, the focus was on smaller groups making a big difference in their communities. These contributions reflect the commitment to delivering Social Value and strengthening the places where we work.
Doncaster Sea Cadets
Through the Doncaster Waterfront project, we engaged with the Doncaster Sea Cadets, whose cabins neighbour our site. During a careers and apprenticeship session, they highlighted an urgent need for building improvements, including roof repairs and electrical upgrades. To meet this need, £4,500 was provided through The Keltbray Foundation to fund essential works, ensuring the Sea Cadets can continue supporting local young people. Doncaster College art students designed and decorated the donation cheque, adding creative touches.
Colchester Sea Scouts
Keltbray also supported the 17th Colchester Sea Scout Group with a donation to purchase new lifejackets, enabling members to safely take to the water in their refurbished boat.
St Clarets Ladies GFC
Keltbray contributed to St Clarets Ladies GFC’s fundraising for a special trip to Limerick, where 30 girls competed in a Gaelic Football tournament. The support ensured every player could travel and take part in this memorable occasion.
Marie Hession, Treasurer of St Clarets GFC and daughter of the club’s founder, said: “The trip was a great success! We won the Cup competitions at both U12 and U14 age groups, so as you can imagine, we had a lot of very excited young ladies. I believe the girls gained so much from this trip: lifelong friendships were formed, their confidence accelerated, football skills excelled, and it was great for us as a club to take them back to their roots to play the Gaelic game they love.”
St Clarets has been teaching and playing Gaelic Football in Hillingdon since 1975 and recently launched under-12 and under-14 teams. This trip marked an important milestone in their development, and we were pleased to help make it happen.

With a long history of working in the City of London and several live projects in the area, Keltbray values the opportunity to take part each year.
The company supported the You Can Build This City event at the Guildhall, where students collaborated to build a model of London using cardboard and craft materials. It also hosted a site tour for a special educational needs school at the 10 King William Street project, giving students the chance to observe construction activities and learn about careers in the built environment.
A highlight of the year was recognition at a Mansion House reception hosted by the Rt Hon the Lord Mayor of London, Alastair King DL. Keltbray was highly commended in the Championing Careers for SEND category, acknowledging its commitment to supporting young people with special educational needs and disabilities.
The success of the London Careers Festival reinforces the importance of careers engagement and introducing young people to the world of work, an area the company has long championed as part of its social value strategy.

MAGGIE'S ST BARTS RAFFLE FUNDRAISING
Making a real difference in the communities where Keltbray works is essential. Through the Stanhope Foundation, the company was introduced to Maggie’s, a cancer charity offering vital support to people living with cancer and their families. In 2025, Keltbray contributed to their fundraising efforts at St Bartholomew’s Hospital in the City of London.
Maggie’s provides free practical, emotional, and social support through a network of welcoming centres across the UK. Each centre, designed by leading architects, creates calm, nature-connected spaces that offer respite from the clinical hospital environment. Visitors can access expert advice from NHS-trained
Cancer Support Specialists, attend workshops, or simply enjoy a quiet cup of tea in a supportive setting.
Keltbray has partnered with Maggie’s on volunteering and fundraising initiatives and supported their annual raffle. The Social Value team wore bright orange t-shirts and walked across London, visiting project sites and the London HQ to sell raffle tickets. This effort raised vital funds, strengthened connections with colleagues, showcased projects, and celebrated the city.
A total of £665 was raised for Maggie’s. In recognition, the charity invited Keltbray to attend the event and draw the raffle, a moment warmly shared by everyone!

ACE2ZAMBIA – BUILDING COMMUNITY THROUGH SPORT
Wentworth is committed to creating opportunities that empower communities and promote social inclusion. In 2025, it partnered with Sport in Action, Zambia’s leading sport-fordevelopment charity, through the Ace2Zambia initiative. This collaboration reflects a shared belief in the power of sport to drive positive change.
About Sport in Action
Sport in Action uses sport as a tool for social transformation, empowering children and young people across Zambia. Its programmes focus on education, health awareness, gender equality, and life skills development, helping those from disadvantaged backgrounds to thrive.
About Ace2Zambia
Ace2Zambia 2025 is a flagship initiative to redevelop the basketball court at Chipata Hubsite in Lusaka. The existing court limits the opportunities for play and community engagement. The project will deliver a high-
quality facility that promotes physical activity, emotional wellbeing, and social inclusion. Beyond construction, the initiative encourages cultural exchange and professional development for local students.
How Wentworth Supports and Why?
Financial contributions enabled the redevelopment of the Chipata basketball court and supported events such as Sport in Action’s 20th anniversary celebrations, where over 600 children received kits and meals. Technical expertise
was provided through the Ace2Zambia team, which produced detailed designs and drawings, working with local contractors and University of Zambia students to ensure construction quality.
Sport is a powerful catalyst for change, offering young people safe spaces to build resilience, teamwork, and confidence: skills that extend far beyond the court.
This support reflects Wentworth’s values of social responsibility and sustainable development, creating a lasting impact through sport and community engagement.

IMPACT BUILDING WITH BEE UNIQUE
Keltbray is proud to continue its partnership with Bee Unique Autism, an award winning charity based in West Cumbria. In 2025, the company supported the Pan Disability Football Tournament once again, reinforcing its commitment to inclusion and community engagement.
Bee Unique Autism is dedicated to supporting, embracing, and educating individuals diagnosed with autism, as well as those involved in their care. The charity creates safe, sensory friendly environments, organises events, and offers social activities that promote wellbeing and inclusion.
The relationship with Bee Unique began in 2024, when Keltbray contributed kit and training equipment for Bee
Unique FC, the charity’s newly launched football team.
Recognising the impact of its work, the company went on to sponsor the Cumbria SEND Games and the Pan Disability Football Tournament. These events provide opportunities for children and young people with hidden disabilities to participate in sport and feel part of a community.
Keltbray was delighted to sponsor and attend the tournament again in 2025. The sense of belonging and joy created by these events is immeasurable, allowing everyone to take part and feel included.
While funding and sponsorship are vital for grassroots charities, the greatest impact comes from giving time and being present, something the company values deeply.

QRRA VETERANS REHABILITATION PROJECT
In 2025, through its data centre project at Richborough Energy Park, Keltbray partnered with the Queen’s Regimental Riders Association (QRRA) Veterans Rehabilitation Project to help complete vital works at their centre in Faversham.
The Veterans Rehabilitation Project was established in response to rising mental health challenges among veterans. The centre provides horticultural, social, and community activities designed to promote wellbeing and mindfulness. Run entirely by volunteers, it offers a range of classes, creating opportunities and a supportive environment.
The building also serves as a clubhouse for the QRRA, which regularly fundraises for veteran related charities. It further acts as an interim measure for veterans facing homelessness, providing hot meals, clothing, and access to showers and toilets.
When the QRRA was let down by a supplier and left without materials to complete its car park, Keltbray stepped in to provide the necessary resources and volunteered time to finish the works. Led by Site Manager Carlos Fernandez, the team repaired the existing
road and formed a roundabout around the rehabilitation centre to improve access for emergency services. The supply chain was also engaged, with Lynch Plant generously providing a roller machine free of charge.
Over several days, Keltbray operatives worked alongside QRRA members, creating a safe and professional entrance to the centre. The collaboration offered an opportunity to connect with veterans, hear their stories, and understand the impact of practical support.
Howard Copsey, President of the QRRA and Leader of the Veterans Rehabilitation Project, said: “We are immensely grateful to Keltbray for its support from the start and for stepping in again to ensure an environmentally compliant track and car park. This has provided a professional entrance to the Centre and greatly improved safety for our veterans. At a time when fundraising is so difficult, Keltbray has lifted a significant burden from us."
Keltbray’s involvement with the QRRA highlights the value of collaboration and the positive impact of practical support.
Case study FEMALE ONLY WORK EXPERIENCE PROGRAMME
Promoting diversity and inclusion within the construction industry remains a priority for Keltbray. In 2025, the company delivered a female only work experience programme designed to showcase career opportunities, inspire future talent, and attract more women into construction.
In June, Keltbray welcomed female engineering students from Westminster Kingsway College – Kings Cross Campus and participants from Construction Youth Trust programmes to its London office. The programme aimed to bring classroom learning to life through practical experiences and career focused activities.
Two site tours demonstrated the company’s capabilities. At the One Undershaft project in the City of London, Assistant Project Manager Alex Joyce introduced students to the challenges of large scale demolition in dense urban environments, including dismantling a unique “top hung” building.
The second visit was to the Western Yards
project, where Project Manager Kevin Murray showcased concrete superstructure methods. Students were taken to the heights of the structure, this time viewing the London skyline from the south side of the Thames.
Alongside the site visits, careers focused sessions included CV workshops, mock assessment centre activities, interview preparation, and an Early Careers workshop with the in-house team. Female staff from a wide range of roles shared their career journeys, providing relatable role models and insight into opportunities within the industry. The students were highly engaged, with outstanding feedback. Many expressed a desire to return, and some did so the following month.
Keltbray plans to host them again in 2026 as they enter their final year of studies, reinforcing its ongoing commitment to fostering a more representative and innovative construction sector.
