I called this company first to repair my old boiler system which had failed - and really wish that I hadn't. Their call out fee is £144 inc. VAT. The guy turned up and said that the electrics in the timer were 'fried' and that it would be unsafe to repair. I would need a new Combi boiler. He quoted me just under £7000 for that but graciously offered to deduct that from the £7000 if I used them to replace the boiler. Stupidly I believed him and got quotes for a new combi installation which ranged from £3000 to £5000. I then got a guy who refused to quote me as it could be fixed with some new parts - it was a simple electrical fault. Cost £350 and is working fine. So I paid £144 for nothing and was then blatantly lied to. Also creepily the guy texted me to ask if I was 'ok' as it was really cold at that time. When I said I was getting other quotes - silence. Avoid this company at all costs.

I have never been in the happy position to recommend plumbers before now. Christmas Eve and disaster strikes as a major leak from an old lead pipe shows in one of our bedroom ceilings. Aziz and Kebba from Certified Group came recommended by a neighbour that had used them a few days prior. I’m so glad that I went with that recommendation as I now have a go to team for all my maintenance and emergency repairs. They were punctual, worked to the highest standard ( as confirmed by my own regular builder who couldn’t attend because he was isolating) The stress of water escape and the ensuing collateral damage was eased by the team. Not only did they sort the leak but organised the building repairs and redecorating all under the one umbrella of Certified Group. They are a group of independent tradesmen about 8 in total that work together for their own company. They have a real pride in the service they offer and deservedly so. A top team to keep on speed dial.

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.

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.
