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.

Called Atag local engineer on a Friday morning, was told needed new valve. Contacted Atag, originally an appointment was made for following Monday. Then got a call to say Atag Engineer could call on the Friday afternoon. Perfect service. Really can’t fault quickness and attitude of engineer.

Epic Service from Start to Finish
I emailed ATAG as my boiler had an issue. They sent someone out within 48 hours of the contact. Tommy who was a very professional and highly skilled technician from Harvey’s diagnosed the problem and changed the parts and left where he worked like he had never been here. Very nice experience indeed I can honestly say it exceeded all expectation the service was brilliant.

The boiler itself is good it's the small issue of you need ATAG installers afterwards. They tell you any gas safe engineer can work on it, yea good luck finding one, spoken over a dozen they don't want to know as soon they find out it's an ATAG.
My local ATAG installer is completely unreliable so now I'm left with a boiler leaking water, the condensate trap seems to be a weak point it's leaked a few times and yet again the ATAG installer is not returning my calls.
I have call & message logs on my phone to prove this, and I've always given him plenty of notice it's not like I'm expecting him to drop everything and come here, I work in electrical installations myself I know what it's like juggling installs and callbacks etc. I never ever leave my customers hanging like this it's utterly ridiculous.
ATAG dont want to know, they won't supply me with other installers in my area.
It's a headache I just don't need, my boilers 6 years old and I'm going to have it replaced with a valiant, I'm done with this.

Atag boiler warranty work
Had a boiler pump problem which was covered by the Atag guarantee. It was repaired swiftly and effectively by Atag contractor. Even after a minor hiccup, the engineer wouldn't give up till all was working properly again. Full marks to him. Very satisfied tenant and landlord! (p.s., I'm in u.k., not u.s. as trustpilot suggests!)😊

From the first report of a fault on my ATAG boiler the team were fantastic. No waiting in long queues, no background music just well trained caring staff who were competent and concerned. They followed up on my calls , they checked with the contract company making sure they kept the appointments, reported back to me at every point and kept me updated. A special mention for the representative from the technical team, unfortunatley I cannot name him but I hope he reads this review and realises how much I appreciated his endeavours on my behalf. Thank you so much. All your hard work appreciated

Very friendly people and engineers. We had to have three visits as sadly the second engineer forgot, in his haste, to turn the return valve so we were without heating for 4 days! Apart from that error, everyone
