Reviews From Our Clients

Service boiler/fire
Extremely pleased, respected the fact that I am shielding, was very friendly and professional and I left a message for him to call me after the job had been finished and paid for because I wanted to check something and he rang me back the same day and was again most helpful. Would definitely recommend.

Replace our broken combi boiler
An outstanding service. Carl always arrives on time for both the quotation as well as for fitting the new boiler. He was so clean and tidy that you wouldn’t have even known he was there. Extremely professional, methodical and organised. I would not only recommend Finselbach Heating & Gas, I would recommend him with absolute confidence.

Leaking combi boiler
Absolutely fantastic service. Called on the day and time as agreed. Fixed the problem and I would definitely recommend the company. Thanks again for a job well done 👏
