The best way to avoid costly boiler repairs is to buy a boiler from a trustworthy and reliable brand. For our boiler reviews, as well as checking the expert views of 219 Which? Trusted Traders, we also conduct a survey of almost 10,000 boiler owners each year.

This means that we can tell you, according to people who own them, which brand breaks down the least, and which is the most well-liked by its owners.

  • 4 in 10 boilers from the least reliable brand developed a fault in the first six years
  • 1 in 10 boilers from the most reliable brand developed a fault.
