Polite and cheerful. Would recommend highly Gareth
for a boiler service.

Always a great service. Easy to book a time convenient to me. I see the same engineer every year (Ronnie Brown) which is great for continuity.

Stephen was absolutely fantastic. He arrived punctually, which immediately set a professional tone. His expertise was evident throughout the job—he worked efficiently, explained everything clearly, and ensured all safety checks were thoroughly completed. Stephen was courteous, tidy, and respectful of the space, leaving everything clean and in perfect working order.

It’s rare to find someone so reliable and knowledgeable. I wouldn’t hesitate to recommend Stephen to anyone in need of a trustworthy and skilled gas engineer. A true professional!

I have booked Certas for all my Oil Boiler needs going forwards in particular I have asked that Stephen attends.

Phillip Davey was my engineer and he came out for my annual service he was very professional and informative! He suggested I needed a replacement and was helpful in arranging that and is very thorough and friendly ensuring all my questions were answered! Highly recommend

Mark Armstrong has been serving our boiler for as long as we can remember. His thoroughness must have contributed to its longevity- it is nearly 30 years old. He respects our house as if it were his own and is always cheerful and chatty.

Super service from Riki. Very friendly and efficient.

Raymond Stewart arrived on time, friendly welcome. Listened attentively to an issue ive i had with a radiator first then carried out the service. Great local engineer
