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.

Perfect equipment and follow up.
I was advised to purchase an Atag heating system by my trusted heating engineer. I have now had it installed for nearly two years and have had no issues. It looks good and does all that it is supposed to. The head office have been in contact to ensure that I am happy and to advise that they have professionals on the end of a phone if I require assistance. That gave me great peace of mind.

Quiet and efficient boilers with good after-sales service
We replaced an old boiler that had reached the end of its useful life (repeated faults, difficulty in getting parts etc.) with a new ATAG boiler integrated with a new Tado smart thermostat system.
The ATAG is noticeably quieter than the old boiler and so far has given us no problems.
ATAG seem to have good after-sales service from what we have seen - of course we haven't - touch wood - had any issues so we haven't had to invoke the warranty, but we have had e-mail reminders just before the annual service is due etc.
Hoping that the ATAG will remain trouble-free for many years!

Good choice for replacement boiler
We needed a new boiler and our local plumber recommended Atag as he fits a lot of them to customers and family alike.
It's easy to use , it's quiet and has saved us money on fuel consumption. It's serviced yearly and since fitting we have had not had any problems at all.

Ours is 2 years old now.
We have had the boiler about two years now, no issues, very easily adjusted for summer/winter. Very happy with the long time warranty as it basically means we'll only pay for services yearly and should there be an issue it'll be covered.
