I had an underfloor heating done in my house and am very pleased with the service provided. The boys were friendly, professional and the job was done within a given timeframe. Communication between me and Marie in the office was great also. Highly recommend👍🏻

Green Heat Wales installed a solar PV system at my home. They did the whole service "end to end" - survey, quotation, advice, and then once I commissioned the installation from them, it was carried out efficiently and promptly, despite this firm being extremely busy. The quality of their work was excellent, and their various specialists (their surveyor, those who put up the panels, the electricians and so on) were knowledgeable and were easy to work with, which was a big plus as we had to make various key decisions during the installation itself. The system has been up and running for around 12 weeks now, and it has worked perfectly, with results even better than those in the quotation. Green Heat Wales are flexible about what products they can use, and they are an "agile" company, one thing that led me to choose them over another firm who also did a survey and sent a quote. I have no hesitation in recommending them.

Had some radiators installed, they arrived on time and got to it straight away, everyone there was amazing and friendly. The office staff communication was great letting me know when the engineers were on there away and and following up the to the date they kept me updated. 110% would recommend to anyone looking for general plumbing to solar and heat pumps

Excellent service from Marie, Nick and the team. My heat pump (ASHP) installation was quite the journey through planning application, design, minor works, installation and commissioning. Altogether this process took almost 4 months, though the vast majority of this time was waiting for planning approval. The pump itself works great and is currently (mid summer) almost free to operate due to solar panels and battery storage. Altogether a great company and a pleasure to do business with.

Very pleased with the service provided by Green Heat Wales. The team provided me with a heat pump design and installation and were very professional from the initial survey to the install of the system, while respecting my property too. Would highly recommend.

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.
