Excellent service as always. It’s like seeing an old family friend when Mark visits now!

Richard,the engineer was excellent. Both in the way he serviced the boiler and sharing his knowledge.

Gareth turned up on time his usual cheerful self.
Talked him through my problem and he fixed it and showed me what to do if it happened again. Then got on and did the annual service.
Gareth has been servicing my boiler for 16 years and has always looked after us well.
No hesitation in recommending him to anybody. He is always happy and helpful

Very thorough , knowledgeable and helpful.
Professional, tidy and could help with all problems.
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

Had my Boiler serviced by Jake Winter today . Rang before he came .
He was very respectful towards my house even removing his shoes when he crossed the carpet .
He informed me what was wrong and what needed to be done in the future and right now . Spent a hour .
He was polite and informative.

Experienced engineer we’ve known for many years. Always good service, feedback and advice.

We moved into our house two years ago and Mark Armstong came highly recommended to us by the previous owners. He continues to service our boiler and is efficient, punctual and provides a professional and friendly service. Thank you Mark!

Annual boiler service carried out by Mark Airey. Arrived on time. Very happy with excellent job completed.

Their engineer is very experienced friendly courteous i have had the boiler serviced by Mark for the last 10 years and always have the greatest confidence in him

Mark Armstrong has been looking after my boiler for the best part of the last decade, I always request him and he never lets me down! Totally professional he is a credit to Certas.

First time I've used Certas for boiler servicing. Good service: friendly and knowledgeable engineer Gareth arrived promptly and completed the job in good time. Refreshing to meet someone who clearly enjoys their job! Probably more expensive than a local boy, but reliable and thus definitely recommended.

The engineer Jake Winter was very polite and efficient.

Prompt, friendly, efficient, clean, everything you would want from a boiler servicing. If Mark Armstrong is an example of the Certas Boiler Team they are seriously well represented.

Reaarranged at short notice. Engineer Mark Armstrong came, as good humoured as always. Quick efficient
