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.

Excellent experience
I have had my ATAG boiler in for several years now and never had any problems with it at all. It has been excellent.
It amazing many people still don't know the name ATAG but these are excellent boilers.
I had a recent simple fault on my boiler, but contacted the company and within hours it was repaired under warranty.
Very satisfied.

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!!!

Fantastic boilers - long warranty
Fantastic boilers at a reasonable price.
I have had 3 x XL Atag Commercial boilers for coming up to 6 years now ( I do get them serviced annually ), however so far not 1 thing has ever gone wrong on them.
I also has 3 x domestic i40R boilers aswell, they are going 2 years strong now, no issues whatsoever.
They have a great technical support team, who are only a phone call away.
When there was a Nationwide shortage after covid of boilers and I was in the middle of my building project,I turned to these guys who had plenty of availability. Service was fast and quick. I will be using these boilers again in my future projects. I highly recommend them, low maintenance, reasonable prices, extra long warranty , better than any other manufacturer.

New Atag Combi Boiler
Purchased a new Atag Economiser Boiler in 2023 complete with a massive 14 year parts and labour guarantee on provisio the combi boiler is serviced every 12 months to maintain the guarantee. It's been great so far, no problems, its easy to use and is more economical meaning cheaper gas bills along the way. I would say we made the right choice in selecting Atag as the tech support is brill and is there to answer any questions if you're unsure of anything. So well pleased with our new Economiser Combi Boiler.

Solid build, great price and very dependable…
Got ATAG boiler 2 years ago when my old Valiant gave up the ghost. I was thinking of replacing it like for like, but my Boiler engineer recommended ATAG, as it comes with 10 year warranty and is, as per him, "solidly made". Been using it for 2 years, did have an issue with the expansion tank in the first 3 months, but that was very efficiently and effectively dealt with by ATAG and no issues since then. I found it to be really well made and definitely more efficient than my previous boiler. Would happily recommend this to all.
