Written by the company
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.

Boiler has had no issues since installation
Boiler has had no issues since installation approximately 12 months ago. Nice and quiet when in operation and much quicker at heating than my previous boiler. Both water and the central heating seem much more efficient

Sometimes things can go wrong
Sometimes things can go wrong, but it is how this is dealt with that matters. When my boiler started leaking, ATAG arranged for a plumber to call and he visited promptly. But then, he completely disappeared from the radar, so Atag arranged for another plumber to attend.
What a difference. The latest plumber was polite, professional and very knowledgeable -fixing the problem on his first visit ..

Efficient and Quiet boiler.
We are a household of two adults aged 60+. The ATAQ boiler completely suits our needs. We can regulate the hot water on a timer to our needs as we dont require constant hot water. The ATAQ boiler is effeient, quiet and easy to operate. The company customer care is very good and its great to know there are a team of dedicated technicians ready to help and advise when and if theres a problem. We've had the boiler serviced after 12 months, which is essential to do and we've had no problems at all with it. However its good to know that the back up from ATAQ is there if required. All in all very impressed with the company and brand

Very unreliable
Very unreliable, We've had an ATAG 30 k boiler for a little over 5 years and has nothing but problems with it.
Stay away from this company as far as you can.

We were hearing a rumbling noise from our boiler.
We rang ATAG and they sent an engineer round.
He was very friendly and very knowledgeable, but as is sometimes the case, our boiler did not make any noises!
He made a few adjustments, and stayed for quite a while to see if everything was OK.
We would really recommend him and of course ATAG

Low costs, very easy and rock solid - whats not to like
When my last boiler became unreliable I asked my gas service engineer which brand he recommended. He suggested ATAG and although I had not come across them before I went with his suggestion. Installation seemed straightforward and setting up the heating controls using the tado app was easy. Overall my gas costs have reduced by a third in the last 2 years and the unit is quiet efficient and light years ahead of my previous worcester boiler. Keeps the house at a good temperature, heats fast and always have plenty of hot water available. A great purchase and thoroughly recommended.
