I highly recommend Solwat for heat pump installation. The entire process was seamless. Kevin, the salesman, was transparent and pleasant to work with—I never felt pressured into a decision. Dan and the design team provided an honest assessment of my options and created a solution that actually fit my needs. The turnaround was impressively quick. Taylor and the installation team were professional, punctual, and finished the job exactly on time. Best of all, they left the place spotless. If you're looking for a reliable team, this is it!

Taylor has made an amazing difference to our heat pump - we are actually warm now! Very knowledgeable and took the time to explain what he was doing. Would highly recommend if you have a heat pump that needs servicing or if you feel it is not performing as desired.

I just had a replacement air source heat pump and I cannot fault the engineers for their professionalism, consideration to my family and their great manners. I am very happy with the instillation they tidied up and went through with the controls with me. I am a very happy customer. Thank you!

Had these guys out to look at my valiant heat pump, which was installed by another company who left it not working properly. After a few visit they have sorted all of the issues and Our bills are much lower. we are now set up on a yearly service plan. Would highly 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.
