Why are so many installers switching to ATAG?

What makes the ATAG way so different? Simply put, we make boilers that are built to last. That’s why we’ve introduced a 10 year warranty as standard for every single boiler we produce.

What’s more, we only supply exclusively to Gas Safe registered businesses.


Today, the ATAG boiler range is the most advanced and efficient in Europe, which has resulted in our industry leading score on Trustpilot. Yet that’s not the only way we’re different.

We only sell to the trade

We are committed to ending unsafe practice in the trade, which is why we’re the only manufacturer to exclusively supply to Gas Safe registered businesses. No compromise.

The best, not the biggest

We’re building a select network of installers who share our passion to install boilers built to last. We call these installers our ATAG Selected Partners – or ASPs. Our ASPs purchase directly from us, which means they can set a price that’s fair for the customer.

Engineered to last

How do we guarantee quality, reliability and durability? By only specifying superior materials and components – full stop. We choose our suppliers carefully; insisting on leading manufacturers such as Honeywell, Grundfos, EBM and Siemens.


Each ATAG Selected Partner is supported by both a local Technical Product Manager (TPM) and an Account Manager. All of our TPMs are fully qualified, Gas Safe registered engineers, and are on hand to practically support before, during and after installation. Our Account Managers keep everything moving smoothly – from making an order through to delivery. Our relationships with our ATAG Selected Partners are built to last too. We will get to know your business quickly, and support you to help it thrive and grow.
