We had our boiler serviced by Mark Armstrong today. He has been maintaining our boiler for many years and as always was polite, efficient and informative. Before we first met Mark we were told we needed a new boiler, but he has kept it running beautifully for over 10 years since!

I recently had my boiler serviced by Riki Urquhart. Very knowledgeable and helpful. He explained why certain parts were having to be changed, which is always good to know.

Excellent service from Riki Urquhart who went above and beyond to get our boiler back up and running. Thank you Riki!

Always an excellent service done. Gareth is lovely.
