We had the pleasure of working closely with Keith on a recent project. Keith's professionalism, expertise, and commitment to quality were evident from start to finish. His seamless coordination and attention to detail played a key role in ensuring the smooth delivery of the job for us. Throughout the process, communication was clear, and his proactive approach made collaboration effortless. We look forward to partnering with Keith on many more projects in the future! Thank you

We are so pleased that Keith was part of our recent renovation project. His expertise in renewable heating is exceptional, and he provided clear, practical advice on how to design and set up our system. The budgeting for his work was spot on, with the final cost matching his original quote exactly—a rare and refreshing experience! For those of you who appreciate good organisation, the files of paperwork we received at the end of the project, including all our guarantees, certificates, and instruction manuals, were brilliant. Thanks to Keith, we now have a warm and cosy home powered solely by electricity. If you're considering a renewable heating project, I wouldn't hesitate to recommend Keith—his professionalism and attention to detail are second to none.

Did a great job replacing a monstrously oversized heat pump with one appropriate for our house. Professional, knowledgeable and always happy to answer any questions. Highly recommended.

Frequently asked questions

How do I know you’re properly qualified and certified to install heat pumps?

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).

Can you tell me if a heat pump is actually suitable for my home?

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.

What type and size of heat pump will you recommend for my property, and why?

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.

What will the full installation cost be, and what’s included in your quote?

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.

Can you help me access government grants like the Boiler Upgrade Scheme?

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.

How much disruption should I expect during installation, and how long does it take?

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.

Will I need to replace my radiators or upgrade anything else in my home?

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.

How noisy is the outdoor unit and where will it be installed?

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.

What warranties, servicing and aftercare do you provide?

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.

What running costs and savings can I realistically expect compared to my current boiler?

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.
