Alan was very professional in carrying out a boiler service. He was immediately able to identify what may have been causing noises in our flue outlet, and advised us on how best to get it fixed. Also, Alan was very communicative and let us know at what time he would be coming, so we didn't have to wait in all day. Highly recommend his services.

Servicing the boiler

Alan has purchased and installed our boiler after visiting us to assess the problems with the old one and advised us about the type of boiler we need and the costs. We employed him to do that after getting 3 different quotes from different individuals. He was very helpful, did the job on time and tidied after he finished. Checked everything was working smoothly. This was 2 years ago. Now he serviced it for the second year and adjusted the pressure. He checked that everything is working fine. He is efficient, engaging and does his job in a very professional way.

Alan helped fixing the issue with my boiler kept dropping pressure. He started with diagnosing the issue and ruling out external factors. Then he explained everything in detail followed by useful suggestions. He then applied the fix, now it’s hassle free. I would highly recommend Alan as your gas engineer to go.

Professional and patient
Alan went above and beyond in helping me get the correct heating system. After picking Alan from a few other engineers he came on the day that was agreed He installed a new Worcester combi boiler along with 4 new radiators. He recommended a towel rail which I'm very happy with as it uplifts the bathroom. On completion, I was extremely happy with his workmanship and left the property tidy I'm really impressed with Alan putting back a tiled boxing better than originally as other plumbers said they would need to smash it out to get to the pipes I would 100% recommend Alan

My central heating had stopped working. I found Alan via Chat GPT, having asked for the names of plumbers with the best reputations in West London. He was the first on the list it generated. He came when he said he would, was very personable and identified and fixed the issue (including having to go to buy the new part required) quickly. He also fixed a couple of radiators that weren't heating as they should without charging any me anything extra for doing so, even though he had to use a new valve on one of them. His good reputation is fully justified and I will now automatically default to using him in future should the need arise.
