About ATAG

ATAG is a premium specialist, known for long warranties on its heat exchangers. You rarely end up with one because an installer grabbed the default. In London, that means they usually sit in homes where the heating was planned properly. The range changes, so check current model details before you rely on anything model-specific.

Faults we often find on a ATAG

  • Control and sensor faults, more often than heat exchanger failures
  • Boilers still inside a long manufacturer warranty
  • Parts that might need ordering rather than coming from van stock

This is what tends to crop up, not a verdict on yours. An engineer checks your boiler in person and finds the fault before giving you a price.

Your questions

Asked about ATAG

Will servicing keep my long ATAG warranty valid?
Most manufacturer warranties need a recorded service every year, and ATAG is no exception. Look at your own warranty paperwork for the exact terms. However long the headline warranty, a missed service is a common reason claims get turned down.
Can you fix and service my ATAG?
We can. Our gas work is done by Gas Safe registered engineers. By law, that is what any gas boiler needs, whatever the make.
