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.

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

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!!
