Water Underfloor Heating
These guys are amazing! Aziz and his team recently undertook some major work on our home, including the complete removal of existing kitchen and slate floor, installation of underfloor heating, plumbing in of new boiler and relocation and replacement of pipe work throughout our house. Everything went so very well, The workmanship was of the very best quality and always undertaken with the utmost care for our home. I wholeheartedly recommend their services, Thank you so much Aziz, Kebba and the team.

Gas Boiler - Installation
I am extremely pleased with the work done by Certified Gas Heating Ltd. I had a lot of trouble finding what I consider a good & reliable plumbing company at affordable prices. Certified Gas Heating ticks all of the above and went beyond my expectations. I like the "customer centric" service they provide - they listened to me carefully and really paid attention to my issues and expectations while also guiding me and providing me good advice to chose a fit for purpose solution that was cost effective to me
Gas Boiler - Installation
Aziz and his team were professional and helpful in every way. They always gave the right advise for the procedure that was being done, though it was not the easy way to get done. Further they went out of their way to do small bits that was not part of the job. Lastly and most important - very neat and tidy work. Thank you guys.
Radiator
Excellent service and quality! Aziz and his team have done great job, identifying the problem and implementing agreed solution in record time. Aziz was very helpful and provided us very competitive pricing on full heating system replacement. His team was very efficient and worked hard to get the work done in short space of time. I probably would have saved myself lots of money and hassle if I would heve received his advice before. Many thanks for great job!
