Our boiler research
Our extensive research enables us to provide you with the most extensive and accurate boiler reviews around.
We asked 10,859 Which? members (May 2016) about the boiler they have in their home. By finding out how each brand of boiler has performed in real homes and how often it has broken down, we can give a reliability score to each boiler brand.
After six years, the least reliable brands are more than twice as likely to have developed a fault than the most reliable.
We also give a customer score to each brand, based on how satisfied Which? members are with their brand of boiler and how likely they would be to recommend it to a friend.
For the second year running, we gathered the views of 179 Which? Trusted Trader heating engineers (April 2016) to provide you with a truly unique insight into the views of the experts who get their hands dirty when fixing boilers every single day.
By asking heating engineers about their views on boiler build quality, how easy it is to get hold of parts and spares, how easy it is to fix a common fault and service and how likely they are to recommend each brand of boiler, we have been able to get a truly unique insight into the reputation of each boiler brand among those that know the most about them.
