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.

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

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!

Excellent job at fair price. Aziz and team completed the installation of two additional radiators in my kitchen and breakfast area, and added a Nest thermostat. I was quoted a reasonable price, Aziz and team were friendly and courteous, and they worked late to get the job completed. More importantly, the work was completed to an extremely professional and high standard! I would not hesitate to both recommend or use Aziz again.

Aziz was great and carried out the work brilliantly. He also fixed a few other things wrong in the flat and charged a fair price. Would def recommend.

These people are in high demand. It was worth the wait to have a trustworthy tradesman. He was transparent about the work and consulted me throughout. He gave me the best advice and did what was best for my needs. You can't put a price on trust. His prices were also competitive.

Great experience throughout the process. From a call within 10 minutes of placing the job, to a quote within days and carried out the work shortly after. They fitted a new boiler and several radiators. Workmanship was clearly visible in terms of their attention to detail, from moving pipes closer to the wall, to repairing drains which wasn't even in the quote, all to ensure a quality finish. Will certainly recommend and use again if needed.

    Hi Andrew, Just seen your Question. To replace your current one pipe system to twin pipe such as flow & return pipes it really all depends on the route and how much pipe work really needs to be installed. Its best you contact me on zero seven nine zero eight two three nine six six five. We can advise you. Thanks Aziz
