Had the team install a Vaillant aroTHERM Plus last autumn. The heat loss survey was thorough and the system was sized properly. Our radiators didn't need replacing and the heating has been brilliant all winter. Highly recommended.

Switched from oil to an air source heat pump and couldn't be happier. Phil handled the BUS grant paperwork completely, I didn't have to do a thing. The install team were tidy, professional, and finished on time. Bills already noticeably lower.

The free survey was thorough and honest. No pressure, just a clear explanation of what my home needed. The installation was neat and clean, and the engineer walked me through the controls. Brilliant from start to finish.

Coming off LPG I was nervous about the switch but Phil's Heat Geek training really shows. He modelled our heat loss properly and the system performed exactly as quoted. Running costs for the year came in well under what we were spending on LPG.

Had solar PV and a battery system installed. The advice was honest, they didn't oversell on panel count, just told me what would work for my roof. Everything installed in a day, all electrics signed off, and my export payments started almost immediately.

New gas boiler after our old one gave up. Quoted on a Wednesday, fitted by Friday. Prompt, tidy, and left the house cleaner than they found it. Very competitive price and the engineer took time to show us the controls. Will use again without hesitation.

After years of expensive oil bills I finally made the switch. SK were patient throughout and answered every question without making me feel silly. The heat pump runs almost silently and the house is warmer than it ever was on oil. So glad I did it.

First winter with the heat pump and I can honestly say we've not once been cold. Phil was right about the ZeroDisrupt™ survey, we kept all our existing radiators. The BUS grant brought the cost right down and the install was done in a single day. Outstanding.
