Heating Services Certas Energy Reviews 

Mark Armstrong is always bright and cheerful, on time and explains everything clearly. Any problems with the boiler are dealt with effectively and he is an extremely tidy/efficient worker.

I could smell oil which wasn’t a good sign, so I contacted Certas ( who I also get the annual service with) and they came out very quickly.
The engineer, Phillip Cooke, was very knowledgeable, explained why and what needed doing and replaced the pump there and then. It now runs much smoother and most importantly no leaks. Phillip was able to demonstrate great all round knowledge and put my mind at ease. Could not been better, was on time and very informative.

Mark is always polite, efficient and professional. He has been servicing our boiler for years and I have always found him to be prompt, personable, knowledgeable and helpful. Thank you for the excellent service you give.

Mark Armstrong had serviced our boiler for many years, he is always polite, very helpful and knowledgeable. He undertakes a very thorough and efficient job. Would highly recommend Mark.

Good communication before the visit. Then on time for the appointment . Polite. Enthusiastic. No mess. Successful. Mark Armstrong has been servicing and occasionally repairing the boiler for over a decade. Fantastic.

We had a boiler issue, engineer Philip Cooke arrived promptly, very friendly & polite,
Found the issues & replaced damaged parts & left area clean & tidy
Fabulous engineer indeed..

I’m really disappointed with the service from Circus Energy. Our oil delivery arrived at least a week late, which is unacceptable when you’re relying on it to heat your home. What makes it worse is that this is the second time this has happened.

There was no apology from an actual person, just a generic automated response that didn’t address the situation at all. When you’re paying for an essential service like heating oil, you expect reliability and at the very least some proper communication when things go wrong.

Being late once might be understandable, but repeating the same issue without any real customer support or accountability is frustrating. Unfortunately, based on my experience, I wouldn’t recommend them.

Our engineer - Phillip Cooke - was politely, friendly, timely and fixed a number of minor issues that would have caused more problems if left unattended. Exactly what you want from a service

The engineer today was very thorough and very pleasant

My elderly mother’s heating was not working properly leaving her upset and anxious, a quick call to Certas Heating Services and an engineer was arranged to call the next morning. Phillip Cooke arrived promptly and carried out a thorough check of the system and fixed the problem. Thank you Phillip for a great service!!

Mark Armstrong arrived early and serviced our outside boiler as he does annually. Mark did his usual thorough job and cleaned the boiler meticulously as ever.

Mark recently serviced our boiler, as he does every year, he’s always cheerful and polite, knows his job, would always recommend Mark.

To start this review I’m gonna say I phoned up at 9 o’clock and by 11:00 Mark had arrived , fixed the problem and he explained what had gone wrong. Everything was clean and tidy on departure. Absolutely phenomenal.
