Built to Last

We do things differently at ATAG.

Our constant commitment to engineering precision matched with our promise to only use quality components, means that our boilers are built to last.

That’s why every ATAG boiler comes with a 10 year warranty on all parts and all labour.

Peace of mind

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 10 year warranty on all parts and all labour. For us, it’s about your long-term peace of mind.

Engineered to last

We manufacture and supply the most energy efficient boiler range in Europe. From our advanced manufacturing facilities in Lichtenvoorde, the Netherlands, our boilers are trusted throughout the world.

We’ve been in the engineering business since 1948, but in 1983 we chose to focus solely on making super-efficient heating products. Our engineers in the Netherlands made a breakthrough in 2013 and developed our patented iCON heat exchanger – the beating heart inside every single one of our boilers. Over the years we’ve worked continually to improve our boilers and won numerous global awards, including being voted best boiler for 8 consecutive years by consumers in the Netherlands. Made with high grade stainless steel, our iCon heat exchanger out performs everything else in the market.

Reducing your heating bills

For homeowners looking for even greater savings, the i-series range of boilers isn’t just super-efficient, it is the most energy efficient range in Europe and can save up to £320 every year on your heating bill (Energy Saving Trust, April 2017).

Keeping your home safe

To ensure the highest safety and professional standards in UK homes we only supply our boilers to carefully selected and legally qualified Gas Safe registered installers. These are our ATAG Selected Partners (ASP). They know how to install an ATAG boiler correctly and service it regularly. And should you require assistance post-install our warranty helpline is open 24 hours a day 365 days a year.

At ATAG, we’re passionate about what we do. We firmly believe that our approach results in high performance boilers that have the lowest cost of ownership in Europe. In fact, it’s this commitment that’s led to ATAG being rated by UK consumers the top boiler manufacturer on independent review site Trustpilot.


To keep the warranty valid you must have an annual service completed by a Gas Safe registered installer. Please note the 10 year warranty is solely applicable to the i-series range, exclusive to ATAG Heating Technology.
