Worcester, Bosch Group, has again come out on top in the Which? boiler report, having been awarded Which? Best Buys for the fourth year running across its complete Greenstar gas fired boiler range.

The manufacturer scored highest in both the reliability and customer satisfaction categories. It had the highest customer satisfaction score of 89% and achieved a reliability score of 79%.

The customer score is calculated from the survey respondents’ overall satisfaction with their brand of boiler and the likelihood of whether they would recommend it to a friend. Reliability is based on the proportion of boilers up to six years old in the survey that have needed to be repaired.

All 30 boilers in the manufacturer’s Greenstar gas-fired range have been awarded a Which? Best Buy accreditation and two in five (42%) people who have bought a boiler in the last six years own one.

The summary of the report stated: “Worcester continues to be the best gas boiler brand. Its customers are the happiest of any brand’s customers in our survey, with a great customer score of 89%. Its boilers stand the best chance of remaining fault free, compared with the 12 rival gas boiler brands included in our survey.”

The report also said: “Worcester is the only brand this year to meet our Best Buy benchmark.”  

Worcester was also mentioned for its oil-fired boiler range, which supply heating for homeowners with properties who are located in off mains gas areas. The Greenstar oil-fired range, which includes 28 different products, received a customer satisfaction score of 79%.
