A little about us

ATAG has been designing and manufacturing boilers for almost 70 years. In that time we’ve set the highest standards for energy efficiency and engineering excellence across the world.

What sets ATAG apart is the fact that we operate in so many countries across the world, with each having their own strict engineering standards. We’ve combined all these requirements that today culminates in our ‘i’ range of ATAG boilers. They’re built to last using the highest quality stainless steel and brass components. Not only are they the most energy efficient boilers in Europe, they also have the lowest NOx emissions meaning they’re kinder to the environment.

At the heart of every ATAG boiler is our revolutionary iCon heat exchanger, which has unrivalled performance and efficiency levels. It’s made from high grade stainless steel and, uniquely, it maintains 98% of its original efficiency levels throughout its lifetime.

Throughout the world, ATAG boilers are installed in large commercial buildings as well as domestic properties and they are trusted to deliver unrivalled performance, efficiency and supreme reliability. This helps to explain why ATAG boilers are also the number one choice for professionals such as architects and design engineers. In addition to winning numerous global awards, UK consumers also rate ATAG the number one boiler manufacturer on independent review site Trustpilot.

Keeping your home safe

We insist our boilers are installed and commissioned to the highest standard, so we’ve invested in our ATAG Selected Partners.

We care about how our boilers are installed so you derive the maximum benefits from your ATAG purchase. That’s why we only supply our boilers to a hand-picked network of legally qualified Gas Safe registered installers. These are our ATAG Selected Partners.

Our ATAG Selected Partners are trained in our entire product range from design to installation and after-care service. They are on hand to offer you excellent advice and the best possible solution that suits your needs.

Safe, efficient and built to last with a 12-year warranty as standard with options up to 18 years; once it’s in the heart of your home, an ATAG boiler is there to stay.

You can verify that an installer is an ATAG Selected Partner by calling 0800 680 0100.

While we make every reasonable effort to vet and monitor the quality and performance of our network of ATAG Selected Partners, we do not accept responsibility for their actions.
