Our signature strengths
Clear guidance from the start
We explain the process in plain language before work begins. You can make decisions with a clear picture of cost, timing, and system changes.
Accreditations that matter
We're MCS accredited and Gas Safe registered. That gives you confidence that your heating upgrade is being handled by properly recognised installers.

A smarter way to heat your home
Air-source heat pumps can cut your reliance on gas and give you a more modern heating system for daily life in Warrington. We install systems that suit real homes, from town centre properties in WA1 to family houses across WA4 and WA5. At A Mellor Plumbing & Heating Services Limited, we help you understand what the change involves before work begins, so it feels manageable rather than daunting.
Our planning covers the heat pump itself as well as upgrades that may be needed to help your radiators or underfloor heating perform properly. That matters because a well-matched system can give you steadier warmth and better efficiency through the colder months. In Warrington, we know you want clear answers, sensible timescales, and work that we carry out properly from start to finish.
Customer viewpoints
Trustpilot
We have replaced our gas combi boiler with an air source heat pump and upgraded our central heating system including underfloor heating. This felt like a big leap and we were reassured by having a dedicated project manager whose information and communication was excellent throughout. Every aspect of the process was clearly explained and all queries answered without hesitation. Mellor managed the BUS grant for £7,500 and the associated work was VAT free which we felt made the price reasonable. The installation was timetabled to suit us, mostly whilst we were on holiday . The team turned up promptly and all work was completed to the agreed schedule and to a high standard. We have signed up for Mellor's service agreement and intend to use them for planned future work.

What the installation process looks like
Changing from a gas combi boiler to a heat pump is a big decision, and we treat it that way with careful guidance from the outset. Our project management keeps communication clear, with each stage explained and your questions answered plainly.
A Mellor Plumbing & Heating Services Limited can also handle the Boiler Upgrade Scheme grant, including support with the £7,500 application where eligible, which can make the move far more affordable. The associated installation work may also qualify for VAT relief, depending on current rules and your property. We schedule work with your routine in mind, because a heating upgrade should not disrupt your week.
Why heat pumps make sense long-term
Our heat pump systems are designed to deliver gentle, consistent warmth instead of the stop-start feel many older boilers create. They can work especially well in homes where you're already improving insulation or updating emitters. Because they run on electricity rather than burning gas on site, they also support a lower carbon approach to heating. With the right design and setup, you get a system that feels future-ready without feeling complicated to live with.
