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.

Dear Steve Cox
I am sorry and disappointed to see that you have once again placed a 1-star review on Trustpilot regarding the receipt of marketing literature.
In my previous response to you on 9th March, I asked that you contact me directly via email at d.allan@atagheating.co.uk so that I could resolve this issue for you and arrange for your details to be removed from all of our marketing lists. To date, I have not received any correspondence from you that would allow me to pass your request to our Marketing and IT teams.
Once again, I kindly ask that you email me directly with your company name and Gas Safe number, and I will ensure that your details are removed from any future marketing texts, emails, or mailings.

ATAG iC Economiser 39 Plus HB
After a lot of research the decision was made to go with the ATAG iC Economiser 39 Plus HB which was installed in 2024.
The installation went smoothly, and since then the boiler has been completely reliable with no issues at all. It delivers strong, consistent hot water and easily keeps up with the demand of a busy household, which was one of the main reasons I chose this model. The performance has been exactly what I was hoping for.
One feature I’ve found particularly useful is the online portal, which lets you see how the boiler is performing. It’s handy to keep an eye on efficiency and usage, and gives a bit of extra peace of mind that everything is running as it should.
Overall, I’d definitely recommend the ATAG iC Economiser 39 Plus HB. It’s been dependable, efficient, and easy to monitor, and so far it’s lived up to expectations with zero problems since installation.

We had an ATAG boiler fitted into our previous house in 2024 and were very happy with the product. We found it economic and efficient. We had confidence in the warranty offered. When we moved to another property in February of 2026 a new boiler was needed, we immediately opted for another ATAG boiler and again are very happy with our choice.

iC Economiser 35+ and One Zone
Installed an iC Economiser 35+ in 2019 and it has generally been great, but after upgrading my WiFi to full fibre and changing network provider I ran into problems with the One Zone controller refusing to reconnect to the WiFi despite troubleshooting all possibilities. Ultimately ATAG instructed a warranty replacement for the controller which slotted in and connected to network no problems, so back up and running within a week. Thanks to Lewis, the technical coordinator for his swift replies and resolving the issue for me.
