The results show overall customer satisfaction scores and reliability ratings.
Which? have asked 10,119 people who’ve had a gas or oil condensing boiler installed since April 2006 about their boiler, using their online consumer panel of Which? members. The respondents have been asked about breakdowns, problems and annoyances with their boiler.
Which? have also asked them to assess how satisfied they were, and how likely they would be to recommend their brand of gas condensing boiler (regardless of their experience of getting the boiler installed). These two questions form the basis of the Which? customer satisfaction score.
