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 service with a smile
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.
