Aziz and Kibba came and did a boiler replacement for me. They were incredibly diligent and pleasant. The work seems to be of the top quality. It is so great to have a boiler that you trust. On my experience, I would recommend certified to anyone.

Aziz and his team came to the rescue late at night when our boiler was leaking. He was very quick to find a replacement and install it immediately, despite the covid situation. Very clean work and professional. We will definitely use them again as they do all sorts of work.

Gas Boiler Annual Service

Certified Gas Heating carried out my annual gas boiler service in September 2020. They responded very quickly to my initial enquiry, sent a written quote in advance and were able to attend within a few days. Aziz and Kebba were thorough and efficient. Aziz gave me very comprehensive explanations. They were careful to adhere to all covid-19 precautions applying to contractors working inside someone’s home and I felt that both they and I were kept very safe. It was a pleasure to do business with them and I will definitely use them for the service next year.

Hands down the best “trade” experience I’ve ever had
Unbelievably personable and professional, honest and straightforward, immaculate attention to detail. Can’t recommend these guys highly enough.

After discovering a ruptured heating coil in my hot water tank, I asked Certified Gas Heating to remove the hot and cold water tanks and install a new hot water cylinder as part of a closed system. This is quite a labour intensive job requiring lots of changes to existing pipework but I was fully briefed in advance and so knew exactly what to expect. The team were always punctual and polite, left the house clean and tidy at the end of each working day and completed the work to a high standard.

I had a new bathroom toilet installed with a multi flap in the waste pipe. I was quoted a reasonable price for the work which was carried out promptly on a day to suit me. Aziz and Kebba carried out the job to a high standard. I’m very pleased with their work and the end result. I found them professional, polite and pleasant to deal with. I will definitely use them again and would recommend to others.
