Scores based on engineer recommendations, ease of servicing, fixing a common fault, availability of parts and spares and build quality have seen Worcester Bosch perform highly.

Carl Arntzen, chief executive of Worcester Bosch, said: “We are beyond thrilled to be recommended by Which?. By listening to feedback from customers and installers, we were able to continue to improve and develop new ranges of boilers and it’s also great to see that our new, innovative Greenstar Lifestyle boiler range is included in this award.

“We are extremely proud to continue to be market leaders in the boiler industry and we look forward to servicing more and more customers in years to come.

In the annual Which? report, which gives homeowners a useful insight into brands to avoid and the comparison between the best and worst boiler brands, it’s revealed that the vast majority of owners are satisfied with their Worcester Bosch boiler.

Matthew Knight, principal researcher for Which?, commented: “Reliability is the single most important consideration when buying a new boiler and Worcester Bosch has it in spades. We’ve been running boiler reliability surveys for 10 years and Worcester Bosch has impressed us every single year.”
