Business growth

While many installers are content with the size of their business others seek growth – whether that is by taking on more work, a wider variety of jobs or expanding from a geographical area.

However, growing a business can often be a conundrum with the day-to-day workload swamping opportunities to identify areas for growth and limiting time for further training in new skills or expansion into other areas.

One route to consider – a familiar one to many in the sector – is taking on an apprentice. Many businesses have used this route to help grow a business, and a number of plumbers working today had their ﬁrst opportunity in this way.

One of the sector’s apprenticeship providers has recently launched a new campaign urging employers to take on an apprentice and invest in their future workforce. The campaign, Powering Apprenticeships. Fuelling Business is being promoted by JTL, an organisation which supports over 8,000 apprentices in partnership with more than 3,800 employers across England and Wales.

JTL says the move comes at a time of mounting pressure on the UK’s skilled trades, noting that demand is growing in core areas such as electrical installation, low-carbon technologies and heating and plumbing services.

The organisation, which works mostly with small and micro businesses, says it provides employer-aligned training, with apprentices trained through its nationwide network of centres and supported by dedicated training officers. It notes that employers with fewer than 50 staff can access fully funded apprenticeships for individuals aged 16 to 21, helping to reduce upfront costs associated with recruitment and training.

Hayler Tabberer, Employer Campaign Manager, said: “Our apprentices are job-ready and supported from the very start. This campaign reﬂects the energy and conﬁdence we see in our learners every day - and in the employers who choose to invest in them.”

Chris Claydon, Chief Executive of JTL, said: “Our campaign is a direct call to employers: if you want to remain competitive, sustainable and skilled for the future, it’s time to take action.” For more information on the campaign and about taking on an apprentice please www.rdr.link/pbt001

Of course, taking on an apprentice is not for everyone and there are many instances where it doesn’t work out.

However, apprenticeships are a well-known pathway for the sector and provide opportunities for both the learner and the employer. Taking on an apprentice is a commitment, but it may just open the door for business growth whilst also helping to support more young people in the sector.

RECORDNUMBEROFRENEWABLESBEING INSTALLED

According to data from MCS, the UK’s quality mark for small-scale renewables such as solar panels and heat pumps, there were a record 170,000 certiﬁed renewable installations in the ﬁrst six months of 2025.

This is a 37% increase on the equivalent period last year, and a 33% increase on the previous highest start to a year in 2023.

The record number of renewables installations includes 30,000 certiﬁed heat pump installations – a 12% increase on last year’s record start to a year.

Ian Rippin, CEO at MCS, said: “Across all renewable technologies, we are seeing a dramatic rise in the number of installations being delivered into homes – helping to reduce energy bills for consumers and drive down emissions. Crucially, there are also more MCS certiﬁed installers than ever before, which means a growing capacity to deliver high-quality installations at volume into people’s homes.

“With roughly 14% of greenhouse gas emissions estimated to come from domestic heating, it’s critical that installations of low-carbon technologies are delivered to a high quality. As installation numbers continue to rise, we’re proud of the vital role that MCS standards continue to play in giving everyone conﬁdence in the ability of home-grown technology to heat and power their homes.”

Charlotte Lee, Chief Executive at the Heat Pump Association, said: “It’s fantastic to see the continued growth in heat pump installations, solar panels, and battery storage into 2025. With electrification firmly on the Government’s agenda, this suite of measures will play a vital role in reducing consumer bills, enabling flexibility, and enhancing the UK’s energy security. The recent Spending Review confirmed £13.2bn for delivering the Government’s Warm Homes Plan, a significant commitment, which we expect to outline further support for the electrification of heat.”

VAILLANTINDUSTRIAL SECURES ROSPA AWARD

Vaillant Industrial, part of the Vaillant Group in the UK, based in Belper, Derbyshire, has secured a 10th consecutive RoSPA Gold Award at its annual celebration of health and safety success.

The achievement of securing this gold accolade consecutively for the past decade also saw Vaillant honoured with the President’s Award, an honour reserved for companies who have achieved a Gold Award between 10 and 14 times successively.

Katherine Stanway, Head of Health, Safety and Environment Industrial at Vaillant UK, said: “Safety is something we continue to review, reﬁne and develop at Vaillant Industrial. This ongoing recognition is very much the result of a team effort and commitment to best practice right across the manufacturing facilities.”

NEARLY A THIRD OFPLUMBERSNOT CONFIDENTMANAGINGTAXES

Almost a third (28%) of plumbers are not conﬁdent in managing their taxes, according to new research by Wavin.

The research found a significant rise in sole traders and younger plumbers lacking confidence in managing their taxes. Four in ten (43%) plumbers who work alone said they were not confident in managing their taxes. Likewise, those at the start of their career lacked the confidence, with the same amount (43%) aged 18-24 expressing that view. Almost half (46%) of plumbers said financial management, such as tax guidance and pricing strategies, was the business support they would find the most useful.

The research was conducted as part of Wavin’s Behind the Pipes campaign.

Dan Scott, Vice President of Northern Europe at Wavin, said: “It is vital plumbers have access to business support, especially those at the start of their career or too busy with client work. Those with experience in the industry can also offer vital support and advice for fellow plumbers.”

NEW‘PLUMBERAWARDS’ SETTO LAUNCH

Designed to “cast a spotlight on the UK’s talented professionals who are setting standards for the sector” the new Plumber Awards has already attracted two industry supporters.

THE HIDDEN COST OF ‘MATES’ RATES’

70% of tradespeople do trade-related favours for friends and family at least once a month with more than one in six saying these favours cost them over £1,000 in lost income annually, according to a recent survey by temporary business van insurance company Tempcover.

Tempcover commissioned a survey of 500 tradespeople to uncover the scale and impact of “mates’ rates” across the UK’s trade community. According to the data, over two-thirds (70%) of tradespeople say they help out at least once a month, with 18% doing it weekly and 8% even more often than that. Just 1% say they never do favours related to their trade.

When asked to estimate how much income they lose each year through unpaid or discounted favours, the average is £552, with one in six (17%) saying the cost exceeds £1,000.

BURTONSMITH PLUMBINGAND HEATING INTRODUCES REAL-TIME ENGINEER TRACKING

Burton Smith Plumbing and Heating has handed its live tracking system over to customers - an idea inspired when a client phoned to ask if he had time to pop out for a carton of milk before his plumber arrived.

The ﬁrm, based in Bedfordshire, says that it realised that by sharing the same live tracking data normally reserved for internal use, customers could enjoy complete transparency about their engineer’s location and estimated time of arrival.

When booking, customers can select a range of time slots: 8am–noon (morning), noon–5pm (afternoon), 5pm–8pm (evening), 8am–6pm (all day) or make use of 24/7 emergency cover. On the day of the appointment, they receive a text message with a live tracking link. If plans change, the system updates instantly.

Toby Burton, Founder and Managing Director of Burton Smith, said: “We’re excited to introduce a feature that makes it easier than ever to know exactly when your engineer will arrive.This technology reduces uncertainty, improves communication, and gives our customers back their time. It’s all about enhancing customer service and making it more convenient - so people aren’t wasting unnecessary time waiting in and are updated every step of the way.

“We believe that we are one of the only plumbing companies in the country to provide this service and what started with a quick call about a pint of milk is now a deﬁning feature of our service, and one we’re proud to offer.”

THREE QUARTERS OF UK VAN DRIVERS SAY EVS ARE RIGHT FOR THEIR BUSINESSES

Three quarters (75%) of UK van drivers now believe that a fully electric van would be a suitable choice for their businesses, according to research from Volkswagen Commercial Vehicles.

The survey of 1,000 UK van drivers reveals cost effectiveness as a key factor driving EV consideration, as 62% of respondents believe that an electric van would now be cheaper to run compared with diesel or petrol alternatives. Charging time (49%) and electric range (43%) continue to top concerns about making the transition.

Craig Cavanagh, National Fleet Manager at Volkswagen Commercial Vehicles, commented: “It’s encouraging to see van drivers embracing the transition to electric, with the majority now recognising the ways in which EVs can support their day-to-day businesses. We continue to enhance and expand our line-up of all-electric vehicles, including the new eTransporter and entry-level ID. Buzz variants, as well as continuously improving our range of partnerships as we support customers on this electriﬁcation journey.”

RESEARCH SHOWCASES APPEALOF WALL-HUNG TOILETS

Wall-hung toilets can increase the appeal of a home, according to new research commissioned by Geberit, with almost three quarters (73%) of homeowners saying a wall-hung toilet ﬁtted as standard in a new home would be appealing.

Geberit’s research polled more than 5,000 UK homeowners. More than eight in ten (84%) said a modern bathroom is important to them when choosing a home, and more than half (56%) said a new-build home would be more attractive to them if wall-hung ﬁxtures were included.

In the survey almost half of respondents (43%) associated ‘modern, premium bathroom design’ and ‘space-saving aesthetics’ with wall-hung toilets, while 83% of those with a wall-hung toilet would recommend one to their friends or family. Sophie Weston, Head of Marketing at Geberit, said: “We commissioned this research to back up what we already knew about wall-hung WCs, so it’s no surprise to see their appeal amongst homeowners. With this evidence, now we can really showcase the beneﬁts to housebuilders, bathroom installers, retail showrooms and end users.

“Wall-hung toilets have become a popular choice to help support design goals, overcoming many of the challenges around space, hygiene and installation. All with more affordable solutions and increased design choices too.”

FAQs PRESSURE REDUCING VALVES

In this technical overview, Ed Morris, Technical Manager at Altecnic, explains all about PRVs, covering why they’re essential, to how they function, and how to select, install, and troubleshoot them.

Q Why do I need a Pressure Reducing Valve (PRV)?

PRVs are installed in residential, semi-commercial and public buildings to reduce and stabilise the inlet water pressure. If the mains or boosted water pressure is too high, then the heating system may not work as intended and the components in the system may be susceptible to damage. The force of water from a tap or other outlet for example, may be too ﬁerce which could cause spray-back. PRVs are designed to reduce water pressure and maintain it to a set level preventing damage to those components installed downstream of the PRV.

Q How does a PRV work?

A PRV opens and closes an aperture based on the set compression of a spring pushing on a diaphragm. The spring tension is set or adjusted via a plate. This relates to a “bar” pressure setting point. Once in operation the pressure of water pushing on the diaphragm is countered and adjusted by that of the spring.

Q Which PRV should I use?

There is a selection to choose from based on the application (cold water or hot and cold water service), with or without a pressure gauge, set using a screwdriver or a Dial up setting.

Q What is ‘Drop-Tight’ control?

When a PRV operates under both flow and no-flow conditions, this is known as “Drop-Tight’ control. “Drop-Tight” control prevents the pressure from “creeping” (an increase in downstream pressure under no-flow conditions).

Can the end user adjust the pressure themselves?

Yes, as the valve works off a spring and diaphragm you can set the outlet pressure by turning the screw on the top of the plastic cover (533 series) or the by turning the pre-adjustable dial up knob complete with pressure setting indicator (535 series).

Can the PRV be installed in any orientation?

The PRV has a ﬂow direction arrow cast onto the body – the valve must be

PRVs are designed to reduce water pressure and maintain it to a set level

installed with the ﬂow in the direction of the arrow. The valve can be installed horizontally or vertically but must not be installed upside down. If the valve is installed horizontally than the cartridge should be vertically mounted.

Q Where should I install a PRV?

The PRV should be installed downstream of the main isolating valve on the cold-water inlet. In apartments these may also be installed after the main inlet valve of the recirculating hot water system. As you may need to access the cartridge for future service or replacement, care should be taken in respect of where the valve is installed so that you have sufficient room to maintain the valve.

QDo I need a strainer in the system to protect the PRV?

The strainer may already be installed as part of the system design. However, Altecnic 533 and 535 series PRVs both incorporate a strainer screen as part of the cartridge assembly.

Q Does varying the inlet pressure have an inﬂuence on outlet pressure?

No, providing the valve is within its technical parameters. PRVs are described as “fully balanced”, this means that varying inlet pressures are compensated by means of the geometry of the valve and therefore have no inﬂuence on the outlet pressure.

Common Trouble Shooting Issues

‘The dynamic PRV is showing a higher downstream pressure than the set point’

Due to the design of the dynamically controlled valve there is no total shut off from the valve seat. If there is no demand the pressure can creep up without regulation. Note: this doesn’t mean the valve is faulty!

‘The PRV does not maintain set pressure’

This could be due to impurities that deposit on the valve seat, causing leakage resulting in an increase in downstream pressure. Scale deposits are the most common cause of PRV malfunction. Clean the cartridge and integrated strainer screen. If the problem persists, install an independent Y strainer upstream from the PRV.

Pressure increases downstream of the PRV can also be caused by back pressure due to a defective check valve being installed, or a check valve not being installed at all. This should be replaced or installed.

‘The PRV isn’t working!’

Is the downstream water pressure less than the minimum I bar operating pressure of the PRV? If it is less than 1 bar do you need a PRV? Is the PRV installed with the ﬂow in the direction of the arrow on the body of the valve?

‘There’s no water pressure!’

If there is no water pressure on the hot and cold supply, then initially check the main isolating valve (to check that it is open) and the strainer (if installed downstream from the isolating valve) to see if it is blocked. Also check the PRV as this may be blocked with debris.

‘There’s hammering/vibrations in the pipework!’

These noises can be caused by multiple number of potential issues, not necessarily the PRV. Issues can be as a result of improperly secured pipes or issues with other products in the system. Sometimes it can be a combination of these contributing factors. If the hammering noise is originating from the PRV then this should be investigated further, otherwise it is likely that the problem is elsewhere in the system.

Water hammer is one of the main problems which can affect PRVs. It is recommended to install special devices to absorb water hammer when ﬁtting PRVs in systems at risk.

QDo I need a pressure gauge?

Yes, in order to check or monitor the pressure in the system. Some engineers prefer to use an independent gauge, but there is an option for the gauge to be supplied with the PRV. Some models are supplied with a gauge port and the pressure gauge can be purchased separately as an accessory if required.

Q What are the maximum inlet and outletpressures suitableforaPRV?

The maximum inlet pressure is 16 bar or 25 bar. Outlet pressure setting range for the 533 & 535 series is 1 to 5.5 bar or 1 to 6 bar depending on the valve series selected with a maximum pressure reduction ratio of 3:1.

HEATPUMP SIZING

Accuracy is critical when sizing a heat pump. In the past, professional experience has often been relied upon by engineers when sizing a gas boiler for a typical home. While many installers are comfortable estimating the required heating capacity of a gas boiler to satisfy a home's heat and hot water demands, a more considered approach is needed for heat pumps.

When it comes to sizing electric heat pumps, the consequences of getting calculations wrong are far more signiﬁcant. An undersized heat pump may not meet heating demand during the peak winter period and would result in increased energy consumption. An oversized unit may run inefficiently, leading to unnecessary running costs and increased wear and tear.

One reason correct heat pump sizing is so important is that electricity is more expensive per kWh than gas (typically by a factor of 3 to 4), a difference known as the spark gap. The Coefficient of Performance (COP) of a heat pump can be 300-400% compared to about 90% for a gas boiler, resulting in less energy being used (and fewer carbon emissions produced) to deliver the same amount of heat and hot water. The spark gap makes it critical to size a heat pump to utilise every kWh of electricity effectively.

Control approval. Accurate calculation of the heat loss in older buildings will be more challenging because of building fabric unknowns, such as potential thermal bridging or poorly installed insulation, but it should still be manageable with a thorough on-site assessment.

Room-by-room

If you do not have heat loss calculation software, there are a variety of online heat loss calculators available to do the job. Regardless of which calculator is used, it is

Darran Smith, Technical Manager from Alpha, looks at the importance of correctly sizing a Heat Pump.

It is also important to bear in mind that while online calculators can give a good initial estimate, MCS-compliant installations must include a room-by-room heat loss calculation based on BS EN 12831. In addition, depending on how the system is configured, the heat demand total may also include an additional figure for hot water demand. The value of this figure will depend on occupancy and usage. For example, if a home is occupied by a large family, then hot water demand is likely to be high, particularly in the mornings. In most cases, this would be managed by a larger or faster-recovering hot water cylinder.

Heat loss calculators work out how much energy is needed to , based on the minimum outside winter temperature for a particular location. The lower the temperature, the more energy the heat pump needs to provide.

Minimum design temperatures should reﬂect the local climate. Using a UK average winter temperature will potentially result in an incorrectly sized heat pump because while -3°C might be a suitable design condition in southern England, temperatures of -5°C or lower are common in remote locations in Scotland. An appropriate minimum value can be sourced from weather ﬁles published by Chartered Institution of Building Services Engineers.

Do also bear in mind that optimum heat pump efficiency can only be fully realised when a system has been sized correctly and is operated at an appropriate temperature. The ideal temperature for a conventional heat pump space heating circuit is 45°C or lower and even cooler where underfloor heating is being supplied. It’s important to size the heat emitter pipework correctly to take account of the flow rate and temperature differential between the flow and return legs, because undersized pipes can force the circulation pump to work harder and result in system noise.

Many of the factors outlined above are interdependent. Investing the time upfront will ensure a heat pump system is efficient, cost-effective and will keep a home comfortable for years to come. This will result in happy customers and fewer call-backs, which is good news for any installer.

OPTIMISE The System

Chris Peden, National Service Manager at Navien UK, explores why reducing peak flow temperatures, right-sizing radiators, and optimising system design are critical for achieving maximum heating efficiency.

Modern condensing boilers work most efficiently when they’re running at lower return water temperatures. Research from NESTA shows that simply turning down the heating ﬂow temperature to 60°C can improve boiler efficiency by around 4%. Lower temperatures allow the boiler to recover latent heat from exhaust gases, which is a key feature of condensing boilers that boosts performance compared to non-condensing models.

To keep the boiler in condensing mode, the optimal ﬂow temperature should be around 70°C or lower, with a return temperature no higher than 55°C. When these settings are met, the boiler operates more efficiently by recovering more heat

from the exhaust gases. This not only reduces fuel consumption and carbon emissions by also delivers meaningful energy savings for homeowners.

But lowering flow temperatures doesn’t just improve efficiency –it can also lead to meaningful savings. According to research by NESTA, turning down the boiler’s flow temperature from 80°C to 60°C could save a typical household around £112 a year on gas bills. This is based on an average usage of 12,000 kWh per year and assumes no change to the room thermostat settings. While the exact figure will vary depending on household size, usage and insulation levels, this simple adjustment could help many households cut costs without compromising comfort.

System balancing is key to ensuring each radiator gives out the right amount of heat, avoiding cold spots or overheating

Supporting older homes

Older properties can make lowering ﬂow temperatures more challenging. Poor insulation, higher air changes per hour and single-glazed windows all contribute to higher heat loss, making it harder to maintain a comfortable indoor temperature at reduced ﬂow rates.

That’s where installers can make a difference. Recommending upgrades such as improved insulation, double glazing, and draught-prooﬁng won’t just improve a home’s energy performance today – it will also help future-proof it for low-carbon heating technologies.

But optimising performance isn’t just about the materials of the building. System balancing is key to ensuring each radiator gives out the right amount of heat, avoiding cold spots or overheating.

Weather compensation is another valuable tool, automatically adjusting the boiler’s ﬂow temperature based on outdoor conditions to save energy on milder days without compromising comfort.

Installers also play a crucial role in guiding homeowners through the small steps that support efficient heating: sealing gaps, upgrading loft insulation, modernising windows, and making sure the heating system is set up to perform at its best. These are the kinds of practical, long-term improvements that really help customers get the most from a lower temperature heating system.

Energy-efficient installations Navien’s boilers are engineered for both performance and adaptability, offering a range of adjustable settings to meet the diverse requirements of modern homes. The NCB range, including the 30kW NCB500 ON combi boiler with its 6:1 modulation ratio, ensures efficient operation by matching output to heating

Installers also play a crucial role in guiding homeowners through the small steps that support efficient heating

demand. Designed to operate effectively at lower ﬂow temperatures – around 60°C for much of the heating season – Navien’s solutions support energy efficiency, cost savings, and long-term sustainability.

Right-sizing radiators

To get the most out of a lower temperature system, radiators need to be correctly sized. Undersized units won’t emit enough heat when the boiler is running cooler, which can lead to customer complaints, inefficient cycling and uneven room temperatures.

The good news is that most existing systems can still be adapted. If insulation and window upgrades have lowered a room’s heat demand, original radiators might still work well. And where they don’t, upgrading to larger or more efficient models is typically straightforward and cost-effective.

When a radiator upgrade is needed, opting for modern designs can make a real difference. Double-panel, double-convector radiators, for instance, can deliver more than 30% higher output than older single-panel types. That extra capacity goes a long way in helping systems work efficiently at lower ﬂow temperatures and in keeping customers comfortable throughout the year.

By understanding how ﬂow temperature, radiator sizing and system balancing come together, you can future-proof your installs and deliver better outcomes for customers.

PHPI takes a look at RIDGID’s C-Style Cutters, that feature a spring-loaded cutting wheel which places constant pressure on the pipe being cut.

A CUT ABOVE

Cutting copper pipe is a nearly everyday occurrence for many plumbers. The C-Style Copper Tubing Cutters from RIDGID have been designed to allow for straightforward cutting in tight spaces.

There are two options in the range, a 15/22mm cutter and a 28mm cutter, which together address the three most common copper pipe sizes. With installers only needing two C-Style Cutters to hand, they can reduce the number of tools they would normally carry to a job.

Contractors are regularly put in situations where they need to not only get to copper tubing in hard to reach places, but may also need to cut various sizes

Quick change

The C15/22 C-Style Cutter has a quick-change feature that allows users to switch between 15mm and 22mm. The second cutter, the C28, has been designed for 28mm copper tubing.

Each cutter comes with a spring-loaded cutter wheel that has been developed to provide constant pressure on the pipe being cut to ensure the job can be achieved as quickly and cleanly as possible.

Wheel replacement

Both cutters also feature the RIDGID X-CEL Wheel Pin for quick-wheel replacement without tools, and without requiring the user to disassemble the housing. In addition, slots have been added around the outside of each cutter for a ﬂat head screwdriver to advance and rotate the tool where access is limited.

AVOID DRAINING DOWN

Lee Parsons, Managing Director of Arctic Hayes, discusses why pipe freezing is seen as a practical, time-saving alternative to draining down – not just in emergencies, but for a wide range of everyday plumbing and heating jobs.

As winter approaches, most plumbing and heating installers are bracing for the seasonal surge in callouts. Burst pipes and frozen systems might make the headlines, but for those in the trade, the more common challenge is far less dramatic: how to complete repairs without turning them into a time-consuming, messy operation.

Draining down a system often sounds like the obvious first step but in reality, it’s rarely straightforward. Stopcocks that don’t shut off properly, tanks that take an age to empty and the risk of introducing airlocks can turn a quick job into an extended one. When you factor in the potential mess – from water left in pipe runs to unexpected leaks – the disruption multiplies. In some cases, particularly with older or more fragile systems, draining down can even create new problems, as shifting water and pressure can unsettle delicate fittings or aged joints.

Freezing

Pipe freezing offers another way; by creating an ice plug within the pipe, it’s possible to isolate a specific section without affecting the rest of the system. The method has been around for years, but its uses are not limited to emergency callouts. Increasingly, installers are

turning to freezing for planned maintenance and routine repairs.

In many cases, a pipe can be frozen and repaired in well under an hour - far quicker than the hour or more it can take to just drain and refill a system. Without having to empty tanks, cylinders, or radiators, the risk of spillage or water damage is significantly reduced. Customers will also benefit from reduced downtime and in a commercial premises, the rest of the building’s water supply can remain unaffected while the repair takes place.

freezing is suited for jobs where only a small section of pipework needs attention

Freezing is suited for jobs where only a small section of pipework needs attention. Swapping a radiator valve, installing a stopcock, repairing a leaking joint, or replacing a faulty pump are all examples. In each of these situations, the engineer can work only where necessary, without needing to interfere with the wider system.

In properties with complex layouts or multiple ﬂoors, freezing can also save signiﬁcant time. There’s no need to chase water back to the header tank or empty a long run of pipework. Everything is kept localised and under control.

A reliable Freeze

While the process is straightforward, a successful freeze depends on good preparation and attention to detail. In most situations, the following steps will produce a dependable ice plug:

PHPI readers have the chance to win one of 10 Arctic Hayes ZEK2 Pipe Freezing Kits. To enter please www.rdr.link/pbt038

Clean and dry the pipe so the freeze jacket or clamp has good contact. Stop water movement by closing upstream valves if possible. Apply the freeze jacket securely and release the refrigerant evenly. Allow the correct freeze time for the type of pipe material and size before starting work.

By following these basics, users can achieve reliable results. With practice, conﬁdence builds quickly and the process becomes a standard part of an installers working method.

Reducing risk and disruption

One of the main advantages of freezing is the control it gives, meaning there’s no need to shut down a whole heating system or disrupt an entire building when only one small repair is required. This can be particularly important in sensitive environments such as hospitals, care homes or busy offices, where any downtime needs to be kept to an absolute minimum.

There’s also the professional presentation to consider because customers notice when work is done neatly, with minimal mess and disruption. Being able to carry out a clean, contained repair reinforces the image of a skilled and efficient tradesperson. While not every situation calls for it, freezing has become an increasingly valued option for engineers who want ﬂexibility on the job. Having the ability to isolate a section of pipe in minutes gives more control and can prevent small jobs from escalating into time-consuming projects.

For installers working in varied environments - from domestic houses to light commercial sites - this ﬂexibility can be a real asset. It’s not about replacing traditional methods entirely, but about having more efficient tools ready to get the job done in the smartest way possible. For

BRINGING IN THE NEW SEASON

As Autumn takes hold and homeowners shift their focus indoors, bathroom design may be high on the agenda. With new styles, finishes, and features hitting the market, it’s a good time for installers to tap into customer demand for smarter, better-looking spaces. Rochelle Barratt, Channel Marketing Specialist at hib. explores the top trends, how to make them work on-site, and, most importantly, how to capitalise on the demand this Autumn.

The rise of the home-spa

The demand for spa-inspired bathrooms continues to grow, with homeowners seeking spaces that combine comfort, simplicity and natural materials. The Warm Minimal look draws on Mediterranean design, focusing on openness, light and tactile finishes that feel serene and refined. Rounded forms, arched details and rainfall showers enhance the sense of flow, while stone, timber and micro-cement bring natural texture. Earthy tones such as taupe, terracotta and olive ground the scheme, creating a calm and restorative atmosphere.

How installers can deliver:

● Recommend ﬂoating wooden cabinets or brushed textural ﬁnishes to enhance the space – they’re a visual centrepiece and a powerful selling point.

● Suggest dimmable mirror lighting or colour-changing LED options to enhance mood and functionality.

● Advise on natural-look materials, whether through wood-effect cabinetry or stone-inspired surfaces, to achieve a harmonious, on-trend aesthetic.

Smarter bathrooms for smarter living

Technology has conﬁdently arrived in the bathroom. The latest innovations are designed to enhance hygiene, convenience, and energy efficiency, all while making daily routines more enjoyable. Smart mirrors with integrated lighting, Bluetooth integration, and demisters have quickly become an expectation rather than a luxury. These elements will revolutionise the bathroom space, as homeowners are looking for ways to keep up the interior design trends, whilst also impressing their family and friends. Similarly, underﬂoor heating is no longer a luxury, as it adds comfort and a touch of indulgence as temperatures drop in autumn.

How installers can deliver:

● Highlight smart mirrors, which combine functionality with sleek design.

● Promote hands-free ﬁttings to clients who are focused on hygiene – a major

selling point post-pandemic.

● Suggest upgrades like underﬂoor heating to elevate the overall experience, especially during colder months.

Designed to last

Homeowners are increasingly looking for bathrooms that not only look beautiful but also stand the test of time. The focus is on high-quality materials, reliable ﬁttings and smart features that make everyday use more comfortable and efficient.

Durable finishes, long-lasting lighting solutions and well-engineered fixtures ensure the bathroom continues to perform and maintain its style for years to come. It’s about combining practicality with design, giving customers confidence that their investment will deliver lasting value.

How installers can deliver:

● Highlight the beneﬁts of robust ﬁttings and the long-term reliability they provide.

● Recommend LED lighting and integrated features in mirrors and cabinets that are built for performance.

● Position quality and longevity as a key part of the bathroom upgrade, reassuring clients their space will remain stylish and functional well into the future.

Nature’s colour palette takes centre stage

Stark white bathrooms are taking a back seat this season as homeowners embrace warmer, nature-inspired tones. Shades such as terracotta, olive, mushroom and muted greens create a calming, organic feel, while deeper hues like red, forest green and black add richness when paired with soft neutrals like warm white and beige. Accent colours, from jewel tones to retro blues, introduce personality and vibrancy without overwhelming the space.

How installers can deliver:

● Introduce colour and texture through cabinetry, mirrors, and tiling options.

● Offer design consultations that help clients choose cohesive schemes built around earthy tones and natural finishes.

● Recommend on-trend ceramics and fixtures that break away from the ordinary, giving customers a more personalised, distinctive result.

Designing for diverse demographics

Understanding your customer is half the battle, and with homeowners spanning every life stage, versatility is key. Young professionals are often drawn to tech-led, statement bathrooms that feel modern and stylish; families need practical layouts with smart storage and safety features; whilst retirees, on the other hand, value accessibility – and we’re witnessing a growing demand for features that don’t compromise on style.

The good news is that these solutions don’t have to be mutually exclusive. With the right planning and product choices, installers can tick all of the boxes.

How installers can deliver:

● Position yourself as a problem-solver: offer bespoke recommendations based on your client’s lifestyle and future needs.

● Emphasise stylish universal design elements like wall-hung vanities (for accessibility and ease of cleaning) and illuminated mirrors with touch-free controls.

● Highlight how good design can be both functional and fashionable - especially important for older homeowners who want accessibility without feeling clinical.

Turning trends into business growth

As new product ranges land for autumn, there’s a clear opportunity for installers to upsell design-led features and stay ahead of shifting customer expectations.

From spa-style sanctuaries and smart technology to durable choices and timeless textures, the trends shaping autumn 2025 are diverse. However, they all point in one direction: a desire for stylish, statement bathrooms that do more than ever before.

At hib., we’re helping installers make the most of that shift with innovative products, on-trend designs, and practical features that homeowners want. Because today, it’s not just about ﬁtting the bathroom, it’s about shaping the whole experience.

Q&A GRUNDFOS GORANGE

PHPI catches up with Neal Saunders, Sales Director, Grundfos Domestic Building Services, to find out more about the new GO range from Grundfos.

QWhy has Grundfos introduced the new GO range?

Grundfos has stood for innovation in pump technology for 80 years now. Our circulators are at home in millions of heating systems worldwide –but today it's about much more than just a new pump. It's about a new era of connectivity, ﬂexibility, and efficiency. We have asked thousands of installers worldwide: What can we do even better? The result is impressively clear: 80% of the installers

surveyed want a pump that is not only highly efficient but also offers high replacement compatibility and perfectly adapts to installation needs. In short: A pump that is easy to install and universally applicable. Just like our new GO models.

The GO range was developed to simplify pump replacements and improve system performance. With just two models –UPS4 GO and ALPHA2 GO –installers can cover the majority of domestic heating circulator replacements, including both UPS and UPM3/UPM4 types. It’s about making life easier on-site, reducing van stock, and ensuring first-time fixes.

Q How many pumps are part of the new range?

There are two pumps in the GO range:

● UPS4 GO – designed for replacing older UPS models.

● ALPHA2 GO – ideal for replacing integrated boiler pumps, post-2015 UPM3/UPM4 models

Together, they cover nearly 70% of boiler circulator replacements, meaning installers only need two pumps on the van.

QFor what kind of situations has the new GO range been designed?

The GO range is tailored for domestic heating systems, particularly service and maintenance scenarios. Whether replacing a traditional UPS pump or a more complex integrated boiler circulator, the GO range offers reliable, energy-efficient solutions. It’s especially useful for post-ErP boilers and systems where performance and compatibility are key.

QWhat are the features of the UPS4 GO?

Designed for both stand-alone and integrated circulators in domestic heating applications, the new UPS4 GO provides enhanced comfort and energy savings for residents. For installers, it makes pump replacements quick and hassle-free.

QWhen on a job, how can engineers check to see which replacement pump is required?

Installers can use the Grundfos GO app. Simply enter the product number of the old pump, and the system will recommend the correct replacement. The app also supports boiler search functionality and provides commissioning reports, setpoint calculations, and bypass valve guidance.

QDo you have any other installation advice for engineers?

Yes –make sure you have the Grundfos GO app on your phone.

The Grundfos GO app goes beyond just recommending a suitable pump replacement. It’s designed to replicate the performance proﬁle of older boiler pumps –especially UPM3/4 models –which often have externally controlled settings that aren’t visible or adjustable from the pump head alone.

The app helps ensure the correct ﬂow rate, bypass valve setting, and ΔT optimisation, which are crucial for system efficiency and comfort. In short, the app isn’t just for reading –it’s for matching and replicating the original pump’s behaviour, especially in more complex or integrated systems. If you’re replacing a pump from a boiler post-2015, the ALPHA2 GO paired with the app is a game-changer.

ROBUST WATER PRESSURE IN NON-TRADITIONAL SPACES

While there has been a steady shift in the way people use properties and external spaces, driven by factors such as post-lockdown home working, a boom in staycations and the creation of home businesses and pop-up shops, the need for adequate or enhanced water pressure may have been overlooked. Mark Ayckbourn, Product Manager at Stuart Turner, discusses what installers need to consider for their clients.

The post-pandemic world pushed many people to reconsider their lifestyles and careers, looking instead at ways to pursue a long-held business dream or simply regain a healthier work life balance. There has also been the rise in staycations, and the potential for homeowners to convert an outbuilding into a holiday let and provide an additional income without a heavy investment.

When it comes to designing and constructing an additional space, while they are full of promise and potential, they often expose an underlying issue: existing domestic water systems are simply not designed to cope with the increased and varied demand.

Garden offices need reliable water for a kettle or small sink, accommodation/glamping pods require consistent pressure for guest showers and amenities, home hairdressers, beauty salons, or small cafes operating from converted outbuildings need commercial-level ﬂow. These are just a few examples of where installers will be crucial in advising how to get the best water performance for the job.

Understanding the challenges

When we analyse the UK’s water infrastructure, despite regulations for 1 bar pressure, the industry is aware that this often falls short especially as demand is only increasing. This comes down to outdated pipes that are fraught with leaks and are unable to support the growing need from homes.

Secondly, there are speciﬁc challenges for each property that an installer will need to assess to understand what solutions will be most suitable for the required output.

Achieving satisfactory water pressure and ﬂow is a common challenge for homeowners, as different systems present unique limitations. Traditional gravity-fed systems, relying on a loft tank, offer only minimal "gravity force" for showers and baths, requiring a boost to deliver adequate power.

While combi boilers, prevalent in 80% of UK homes, suffice for 1-2.5 bathrooms, they often struggle to maintain consistent pressure for multiple showers or high-demand ﬁxtures like rainfall showerheads (which require 15-18 litres

per minute) due to a typical legal mains limit of 12 litres per minute.

This means that to truly enjoy powerful showers or simultaneously use multiple outlets, homeowners often need to go beyond a standard combi boiler, requiring a solution that can either draw directly from the mains and boost, or utilise a break tank to overcome ﬂow restrictions.

Common side effects that installers may encounter include weak showers, slow-ﬁlling appliances, and multiple outlets struggling simultaneously. When it comes to operating a business or wanting to create guest experiences, these are elements that can dramatically impact operation and comfort. However, water pressure is still quite often the last consideration for people despite being an integral part of water usage and experience.

Making improvements

Boosting solutions offer an effective way to overcome common water pressure limitations in both residential and

Boosting solutions offer an effective way to overcome common water pressure limitations in both residential and commercial settings

commercial settings. For example, the Stuart Turner Monsoon Professional range offers advanced variable speed technology, intelligently adjusting pump speed to meet demand, guaranteeing constant pressure even when multiple taps, showers, and appliances are in simultaneous use. This makes it ideal for properties needing a robust boost to their vented or combi boiler systems, ensuring powerful and consistent performance for everything from rainfall showerheads in a holiday let to multiple basins in a home beauty salon.

For larger demands, especially where mains water ﬂow is restricted, the Stuart Turner iBoost systems provide a comprehensive solution. These integrated units combine a high-performance pump with a generous cold water storage tank, ensuring ample supply, all while meeting stringent compliance standards such as CAT5 for commercial applications.

Supporting customers

By harnessing technology, such as pumps or high-pressure storage systems, installers can support their customers in home projects, particularly those considering business ventures or rentals. As this trend continues to grow, there is also an increasing challenge around water pressure that will require solutions such as water pumps and boosters. Aligning with a reputable brand and products that provide peace of mind is therefore crucial for installers to consider.

HEATPUMPS SEIZETHEOPPORTUNITY

The numbers tell a compelling story.

The UK government wants to leap from around 30,000 heat pump installations before 2020 to 600,000 annually by 2028 – that's a twenty-fold increase in less than a decade. But here's the challenge: there simply aren't enough skilled installers to make it happen. And here’s the opportunity: if you're already Gas Safe registered and working in heating, you're well positioned to ﬁll that gap.

This isn't just another government target destined to fall short. The UK heating industry is experiencing the most signiﬁcant transformation in decades, creating what could be the business opportunity of a lifetime for heating professionals ready to act now.

The pressure comes from multiple directions, and it's not going away. The legally binding Net Zero commitment by 2050 has put residential heating ﬁrmly in

the spotlight – after all, domestic gas combustion accounts for roughly 14% of UK greenhouse gas emissions.

Add volatile gas prices and genuinely growing environmental consciousness among homeowners, and you have real consumer demand for heating alternatives that promise both lower carbon footprints and potentially reduced running costs.

The result? The industry needs many more qualiﬁed installers within just three years. For heating professionals who move quickly, this represents an unprecedented chance to get ahead of the curve in a rapidly expanding market.

Halfway there

Here's the best part: you don't need to start from scratch. If you are already working with boilers and central heating systems, you possess the core skills that translate to heat pump installation. Your understanding of system design, water circulation principles, and complex installations provides a foundation for developing heat pump expertise.

Think about what you already do well. You manage customer relationships, deliver quality workmanship, and solve heating

problems under pressure. You understand how heating systems work, you know your way around pipework, and you've built a reputation for reliable service. These aren't just transferable skills – they’re exactly what the heat pump market needs.

Rather than requiring a complete career change, moving into heat pumps is more like adding another string to your bow. You're expanding your technical knowledge, not rebuilding it from the ground up. And that experience gives you a massive advantage over newcomers trying to enter the market without your background.

Training

Leading manufacturers, like Daikin, have invested heavily in training programmes that go far beyond basic product familiarisation. The Sustainable Homes Network (SHN) offers structured pathways that let you build expertise progressively while keeping your existing business running.

The key is ﬁnding training that combines proper classroom learning with hands-on experience using real, working heat pump systems. This practical approach proves invaluable when you're trying to understand the nuances of different technologies and how they work across various property types and heating requirements.

Look for programmes that also offer discounts on professional certifications like MCS accreditation – removing the financial barriers to achieving recognised qualifications in renewable heating.

Business support

Smart manufacturers understand that training alone isn't enough. That's why programmes like Daikin's SHN extend into comprehensive business development support. This means lead generation systems that connect qualified installers with potential customers, co-branded marketing materials that enhance your professional credibility, and reward schemes that provide tangible financial benefits.

The progression pathway is clear and manageable. Complete your initial training and you can start installing. Finish three installations with manufacturer support, and

you unlock access to installer locator listings and lead management tools. This graduated approach lets you build conﬁdence and competence systematically, rather than facing overwhelming demands from day one.

For those wanting to go further, expert-level certification becomes available once you achieve MCS qualification and complete advanced training courses. These higher-tier programmes offer enhanced financial rewards and priority technical support – clear incentives for continued professional development.

Technical assistance

Perhaps the most valuable aspect of manufacturer-supported programmes is the ongoing technical assistance. Priority access to technical helpdesks and expert commissioning support ensures you can maintain service quality standards during the learning curve associated with new technology.

Free commissioning support for your initial installations helps build conﬁdence while ensuring customer satisfaction. This manufacturer backing signiﬁcantly reduces the business risks of entering a new market segment – technical expertise remains available exactly when you need it most.

Reliable warranty options further enhance customer conﬁdence while protecting your reputation. These

comprehensive support networks recognise that successful market development requires sustained commitment, not just initial training followed by radio silence.

Market growth

The numbers work in your favour. Early adopters are positioning themselves for sustained business growth as market demand continues expanding. The current skills shortage means qualiﬁed installers can command premium pricing while building strong customer relationships in a genuine growth sector.

Better yet, modern training programmes are designed to work alongside existing business operations. You don't need to make immediate wholesale changes. Instead, you can diversify your service offering strategically while maintaining established revenue streams.

The transformation of UK heating represents more than technological change – it's a pathway to future-proofed business growth for professionals prepared to embrace new opportunities. With training infrastructure now in place and substantial market demand emerging, the question isn't whether to engage with the heat pump market. It's how quickly you can position yourself to capitalise on this opportunity.

RECOVERY TIME

Neill Ovenden, Operations Director for LCL Awards, looks at the opportunities for plumbers in Mechanical Ventilation with Heat Recovery (MVHR), a technology suited to new-build, air-tight homes.

Modern homes are increasingly being built with high levels of insulation and near zero drafts, great for efficiency and keeping energy bills low, but not so great for fresh air circulation. To generate heating and cooling, often without the need for an additional wet system and ensure air in these more ‘passive’ homes is clean and healthy, MVHR systems offer a solution.

How they work

MVHR systems go beyond more traditional ventilation methods such as trickle vents and extractors – they bring in fresh air whilst extracting heat from outgoing, stale air and can provide a total heating and cooling option in air-tight properties.

Warmth is taken from the moist air commonly found in kitchens and bathrooms and passed through a heat exchanger to capture approximately 80% of the heat, which is then used to raise the temperature of in-coming fresh air distributed around the home. The reverse happens in the case of cooling.

Independent ducted fans extract and draw-in air, with ﬁlters that remove pollution and airborne allergens. Apart from cleaning and warming air, MVHR systems also contribute to preventing condensation and damp by removing moisture.

Minimal

drafts

MVHR systems work best in properties with minimal drafts as they replace the air extracted from a room with a similar volume of warmed (or cooled) air. If a room is drafty, outside air will compromise the

temperature of the air being introduced. The level of airtightness at which MVHR will start to be effective generally starts at around 5m³/hr/m².

Retroﬁtting MVHR to older properties is possible but hiding the ducting within the fabric of the building can be problematic. Additionally, older properties also tend to be less airtight.

Transferable skills

Plumbers have transferable skills suited to ﬁtting MVHR systems:

● Pipework and ductwork: Routing ducts is comparable to running pipes – both require accuracy and neatness.

● Commissioning: MVHR systems, like heating systems, must be balanced and tested to perform properly.

● Plant spaces: MVHR units are often sited in cupboards or lofts – environments plumbers already know well.

A boost for business

For self-employed plumbers and small ﬁrms, MVHR offers a growth market. By December 2026 the Future Homes Standard will become law, by December 2027 all new homes must comply and from 2028, all new housing schemes must incorporate a low carbon plan from the outset.

Working with housing developers could therefore provide a steady stream of work for many years to come. Once installed, MVHR systems require servicing and maintenance – cleaning and/or changing the ﬁlters, while making sure external terminals are kept clear of debris.

The fact MVHR systems offer cooling is key. At the time of writing, we are coming out of an extremely hot summer. With climate change causing high temperatures to be more commonplace, year-round mechanical temperature control is becoming a sought-after feature.

For self-employed plumbers and small firms, MVHR offers a growth market

Future-proof your business

The government has ambitious targets to build 1.5 million new homes by 2028/29, which will include low-carbon alternatives to fossil fuels, including MVHR and also heat pumps – a technology that many plumbers have already familiarised themselves with.

With the Future Homes Standard looming, the transition to sustainable housing is well underway, with all-year energy efficient climate and air quality control becoming a vital part of modern living.We’re keeping an eye on the evolving market and will be adding MVHR qualiﬁcations designed for existing plumbing and heating engineers to our portfolio soon.

WATCH ALTECNIC DRY TRAP TUNDISH

In this video on the PHPI YouTube channel Richie, from RJ Heating, takes a look at the Altecnic Dry Trap Tundish before fitting it at a customer’s property.

Altecnic says its 128-2010 dry trap tundish has been designed for use with heat interface units (HIU), domestic central heating boilers and hot water cylinders to pass the hot water discharge from pressure and temperature relief valves.

On this installation Richie is replacing a cracked tundish sited in a garage which was damaged by a customer.

Richie comments: “The reason I like using the Altecnic Dry Trap Tundish is because it’s time cost and space-saving. You’ve only got to buy one product, that effectively takes the place of two. You’ve not got to worry about fitting a tundish and a trap. It’s less connections, less to leak, less to go wrong.”

The Altecnic dry-trap tundish has been designed with a transparent chamber to provide a visual indicator for discharge. The company says there is no need to install both a tundish and a dry trap because the unit features an internal stainless-steel spring-loaded disc mechanism that has been designed to prevent odours from escaping.

Richie notes: “It was quite a nice, easy installation. There’s only two connections you have to worry about. You have 15mm at the top and 22mm at the bottom so it can retrofit quite easily into most systems.”

NEWWATERLESSTRAP FROM WAVIN

Wavin has launched a new version of its HepVO waterless trap, designed to make installation as straightforward as possible.

With an updated design that still features the sanitary seal, the company says this latest HepVO trap is easier and simpler to install than any of its predecessors.

A new addition is directional ﬂow arrows on the underside of the ﬁtting, designed to make it easier to align for installers when operating horizontally.

The original HepVO was a practical solution to traditional traps, which can lose their water seal due to evaporation, siphonage, leaking or movement. The HepVO waterless trap was designed to solve this problem with a self-sealing, elastomeric membrane performing the same function as a water-ﬁlled trap, but without the potential drawbacks. The company says this membrane has proved very popular with installers over recent years and has not been altered in the latest version of the product.

Steve Skeldon, Product Manager, Above Ground at Wavin, said: “We’re always looking at how we can improve our offering for customers. The original HepVO proved a real hit, but by redesigning the product we now have a more modern-looking waterless trap, that also has great durability with a fantastic 15-year guarantee.

“Installers can get the job done quickly and easily, providing end-users with a system that won’t let them down. Our original HepvO was as a ﬁrst for the plumbing and drainage industry, and with more than 30 years of experience, we’re proud to be continually improving our offering for customers with world-leading products.”

WAVIN

Hep2O Keyless Push-Fit

In this video Stanley takes a closer look at the Hep2O Keyless Push-Fit System from Wavin. The system was developed with direct input from plumbers and installers with the keyless range addressing the challenges of lengthy installation times and difficulties in confined spaces. Stanley picks up on this point noting: “[One] thing they have managed to do is make the fitting smaller and slimmer, which is great for us because we work in tight spaces –behind cylinders, under sinks, behind toilets, under baths.” The Hep2O Keyless system incorporates Wavin’s In4Sure technology, which secures joints with a distinctive ‘rumble’ during installation. Stanley says: “One of the other features I really liked was the In4Sure system. It gives you positive feedback, that your pipe is definitely inside, all the way into the fitting.”

REMS

Mini Press 22v Press Tool

In this video on the PHPI YouTube Channel, Angelo from Division Gas & Heating tests out the REMS Mini Press 22v Press tool. During the installation Angelo uses the M proﬁle jaws with the REMS Mini Press, although the tool can also be used with U and V proﬁle jaws.

Upon completion of the unvented cylinder installation, Angelo comments: “I had roughly between 40 and 50 to actually press. Took me 30-35 minutes to do that, and if I was soldering the prep work in cleaning the pipe work, ﬂuxing the pipe work and actually soldering it would have taken me twice, if not three times as long.”
