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.

Great product
I have had the Economiser 35 combi for 2 years now and it has been a great investment. Large initial outlay in comparison to others however the savings on bills are huge and the long warranty for me makes it a great decision.
No issues as of yet so I am happy.

Potentially Dangerous Fault
We have had to call in the gas safety engineer because our under warranty ATAG boiler developed scorch marks on the exterior of the boiler in a period of only five hours or so. We are waiting to see what the solution is but this seems to be dangerous to me and the Emergency gas safety engineer warned that they would’ve been carbon monoxide released!!
As a follow up, I can’t fault the service from ATAG to get the boiler up and running ASAP, but it still remains a one star review because of how potentially dangerous the failure mechanism was.

Error 151, an error that just wouldn’t go away!
We’ve been having an error with our boiler for a few days which cleared with a reset. However it wasn’t permanent, the fault reappeared again. After a call to ATAG call centre a representative was onsite just a few hours later. Absolutely great service.

It’s Jan 2nd and the weekend is here.
It’s Jan 2nd. It’s turned exceptionally cold. I can’t get my central heating to work as a consequence of there being some sort of glitch with the company’s software.
Snow is forecast and now it’s Friday evening. I have no idea when I’ll be able to turn the heating on. I was told over the weekend a message could be left on an emergency hot line.
It’s not the first time this has happened. I cannot tell you just how annoying this is…it feels the same as if I’d bought a lift jacket only to find out when putting it on I sink.
I was talked into going with ATAG by a local firm and paid a premium for it.
Do you think I’d would go with ATAG again?
