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.

Reassuring and supportive
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
was superb
All the communication was excellent. It was an unfortunate oversight. I rate the service overall very highly.

Dear Mrs Elaine Bygrave
Thank you so much for your kind words about our team and engineers.
We’re very sorry for the inconvenience caused by the issue with the return valve — that certainly isn’t the standard we aim for.
We appreciate your patience and understanding while we resolved it, and we’re glad to hear that you found everyone friendly and helpful throughout.
Your feedback helps us improve, and we hope to serve you even better next time.
Kind regards

ATAG saying 'not our problem'
Went through ATAG and they passed my details onto an installer. Installer bodged everything including damaging cupboards and numerous other items. Contacted installer about the horrendous water hammer since installation and they stopped communicating.
Pipework was so bad we had to have it all removed and replaced costing hundreds.
Since then the boiler has failed on two occasions (less than 9 months old) and so have raised the issue with ATAG.
After 7 weeks I finally received a response and they have refused to accept any responsibility. I wasn't even asking for any contribution - just that they would check and resolve the installation.
I'll be recommending friends and family to avoid.
*** UPDATE ***
After 7 weeks of nothing and then a full day of emails back and forth and requesting 3 times for this to be escalated, I posted the above review (a name has since been removed). 9am the following morning the manager (who was cc'd all the previous day) deigns to call me to resolve the issue, asking me to take down the review first and they will sort. I asked them to put it in writing first but unfortunately it fell short of what I had asked for.
So, the review still stands, only now I am even more disappointed.

Boiler mended under warranty
Last December we moved into a new house. We had no experience of gas central heating having lived for many years in flats.we had no information about the system in the house. A local heating engineer serviced the boiler but then said there was a fault and he couldn’t mend an ATAG boiler! We contacted ATAG and were promptly told the boiler was still under warranty. The repair was completed at no charge. The engineer, Steve was really excellent and a total pleasure to deal with. We will be getting him to service the boiler in the next month for this winter.

The fault was found on Tuesday the part was ordered the same day and the repair was carried out on Friday. The engineer checked both the hot water and heating and said that both were working properly but should I have any problems then ring Harvey’s immediately. I call that good service.
