Huge thanks to ASME for converting our house to renewable energy. ASME retrofitted a heat pump and then saved us from a terrible solar installer. Mark's advice has been essential to the success of the projects, and Andy's care and attention to the installation means we can now site back and relax safe in the knowledge that it's all a job well done.

After contemplating solar and battery installation for some time, our decision to choose AS Mechanical and Electrical Ltd was easy. We felt confident to proceed after our house had undergone a comprehensive survey by ASME to calculate our energy usage, current and future, which was presented in a clearly explained tailored plan. This included contingencies for extra output to cover power cuts, future electric cars and possible heat pump. We installed a 5kW system with a 12 panel array and a GivEnergy 9.5kW battery storage and are delighted with the result. Not only is our system efficient and practical, but was also delivered in a professional and timely manner. Workmanship was exemplary throughout and carried out to exacting standards. Since installation we have used almost no electricity from the national grid so our bills have drastically reduced. We could not be more delighted with our new solar system.

Last year when energy prices spiked I began realise that my energy costs needed to be bought under control. I also had concerns about the potential for blackouts (given this was being widely reported by the press) and how this could impact my business that relies heavily on being online. I was recommended AS Mechanical and Electrical by a friend who knows the market. I did not go into the process lightly and among other things, asked the firm to provide evidence of their competancy. The work was slightly delayed due to matters beyond the control of the installers, but the work was carried out to a high standard, so much so that an inspector auditing the work commented that it was "one of the best installs he had seen". I now have an excellent system which has reduced my "grid dependency" by 90% since the install was completed in March 2023. I would have no problem recommending the firm due to the high standard of workmanship and professionalism shown throughout the process.

Andy, Mark and their team are brilliant. They really know there stuff when it comes to renewables. This was essential for me in a property that required some specialist knowledge to achieve a heat pump solution that worked efficiently. They're very pleasant to deal with, have amazing work quality and are very responsive. I'd recommend ASME every time.

Mark, Andy and their team coached us through a difficult process of upgrading our thermally inefficient home. We’re now cosier than ever with a heating system that is working perfectly. All of the tradesman on the team were pleasant and professional. Would recommend!
We are MCS‑certified and registered with an approved consumer protection/competent person scheme, which is essential for quality assurance and to access grants like the Boiler Upgrade Scheme (BUS).
We carry out a detailed home assessment, including property type, insulation levels, existing heating system and available outdoor space, to confirm whether a heat pump is a good fit.
We design the system using a heat‑loss calculation for your home, then match the correct kW size and model (for example, air‑source vs ground‑source) so it runs efficiently and reliably.
Our fixed quote clearly lists the heat pump, cylinder, controls, labour, scaffolding (if needed), electrical work and any radiator or pipework upgrades, so you know exactly what you’re paying for.
Yes, as an MCS installer we can confirm your eligibility, apply for the BUS grant (worth up to £7,500) on your behalf and deduct it directly from your quote.
A typical air‑source heat pump installation takes around 2–5 days, and we’ll agree locations for the indoor and outdoor units, manage any planning considerations and keep you informed each day.
After the heat‑loss survey, we’ll advise if any radiators, pipework, electrics or hot‑water cylinder need upgrading so the system can run efficiently at lower flow temperatures.
Modern heat pumps are designed to be quiet and must meet UK noise regulations; we’ll position the unit to minimise any impact on you and your neighbours and comply with local planning rules.
You’ll get manufacturer warranties on the heat pump plus our workmanship guarantee, and we offer ongoing servicing and support to keep your system performing at its best.
We’ll estimate your likely annual running costs and potential savings based on your current fuel type, insulation level and tariffs, using real‑world performance data rather than lab figures.
