We do things differently at ATAG. Our constant commitment to engineering precision, matched with our commitment to only using quality components, means that our boilers are built to last. Spending money on a new boiler is a big investment, and you need to be sure that it’s going to keep you warm for years to come. That’s why every ATAG boiler comes with a 12-year warranty, with the option to upgrade to 18 years on all parts and all labour. For us, it’s about your long-term peace of mind. ATAG boilers can only be bought through an ATAG Selected Partner (ASP). All of our ASPs are legally qualified Gas Safe Registered installers who know how to install an ATAG boiler correctly. We only sell to gas-safe installers because we need to know you’re in safe hands all the way. To find out more, visit www.atagheating.co.uk.

ATAG BOILER
ATAG BOILER
My wife and I decided to install a new boiler and radiators. Prior to this we invited 3 different plumbers to come and view the property and provide us with a quote.
Only one plumber actually came back to us and provided us with a quote, partially due to the complexity of the boiler having to be moved from down stairs to upstairs and a new gas pipe having to be installed in the process.
Derek Scott from Deronne,Daies,Premnay,Insch, AB52 6QN knew exactly how to go about the task and provided us with a quote that we found acceptable, on his recommendation he advised us to fit an ATAG boiler, on the basis that he had been installing them for a number of years with very little or no problems after installation.
The boiler that we had installed is an ATAG IC Economiser 35 Plus combi boiler, which comes with a 12 year warranty, which we can control via the Hive control system.
This boiler is super efficient and quiet as it is located in an old airing cupboard which used to house the hot water tank from our old heating system.
On the back of us installing an ATAG boiler, my sister in law had Derek Scott install a full new heating system including all pipe work and radiators and a ATAG Boiler in her property also.
I would have absolutely no hesitation in recommending this type of Boiler should anyone be looking to upgrade their heating system.

Dear Bert Marr
Thank you so much for taking the time to share your detailed experience.
We're delighted to hear that you and your wife are pleased with the installation of your new ATAG IC Economiser 35 Plus combi boiler. It's great to know that Derek Scott was able to provide a clear solution for what sounds like a challenging installation, and that the system is performing efficiently and quietly in its new location.
The i-series of ATAG boilers is renowned as the most efficient in Europe, and the Economiser is also among the quietest boilers in the UK, having been awarded the Quiet Mark in 2021.
We're also thrilled to hear that your sister-in-law trusted Derek to install a full new heating system based on your recommendation. Word of mouth is invaluable, and we truly appreciate your confidence in both the ATAG boiler and the service you received.
Thank you again for your kind words and strong recommendation—it's feedback like this that helps others make informed decisions when upgrading their heating systems.

Terrible warranty service - DO NOT USE!
I had an ATAG boiler fitted in 2019 and this had been reliable until recently when the boiler was constantly firing up and I couldn’t work out why. A plumber attended who also couldn’t establish the reason for it. But that was fine because I had an extended warranty from ATAG, no problem? WRONG. I called ATAG and they have continuously failed to send any engineer to look at the boiler. This has been going on for over 6 months with no engineer having been sent. Will be logging a formal complaint today and will update on the outcome.
Shocking service - DO NOT go with ATAG if you actually want proper warranty cover!!!
