So you’ve taken the decision to invest in a new boiler. In doing so you’ll reduce energy bills significantly, especially if your old system is inefficient. But which boiler brand should you look towards?

Fortunately consumer watchdog Which? have drawn up a list of the best and worst rated boiler manufacturers, as given by customers.

As you’ll see, there’s quite some difference between the best and worst, with the top companies receiving scores of 84% and the worst just 44%. Two of the national brands stand out for being better than average, so take a look at the customer satisfaction table below:

According to this table, the average customer score given by Which? consumers is 74%. In total there were 5,046 responses to the survey. Respondents for each brand were as follows: Alpha (73); Ariston (32); Baxi (361); British Gas (231); Ferroli (43); Glow-worm (446); Ideal (312); Halstead (43); Main (40); Potterton (291); Remeha (39); Vaillant (903); Viessmann (103); Worcester (1,911).

Gas boiler reliability

Which? also carried out a reliability score for boiler manufacturers in the UK. Scores were based on the number of boilers needing repairs.

See the reliability table below:

Again, the average reliability score is 74%, with a total of 3,846 responses.

How are brand customer scores calculated?

Which? completed their research in June 2013, asking about gas and oil boilers which have been fitted in the UK since 2005. As part of the survey, Which? members were questioned on breakdowns, problems and any issues that had risen over the years.

The customers were then assessed for satisfaction and how likely they would be to recommend the same brand in the future. Both of these questions form a considerable proportion of the final score.
