If your boiler has let you down this winter and you’re looking for something more efficient, don’t assume you’ll get the best deal from the biggest name on the market.

An investigation by Which? has found that on three separate occasions British Gas quoted up to twice as much as the lowest-priced independent heating engineer for the same boiler replacement job.

Wide gaps

The investigation was sparked after several Which? members highlighted wide gaps between British Gas quotes and other quotes for boiler replacements and services.

The consumer group compared British Gas quotes against those from independent central heating engineers recommended on its recommendations website Which? Local.

Spot the price difference

British Gas quoted £3,997 to replace a 12-year-old combination boiler with a new Vaillant ecoTEC pro 28 in a one-bedroomed flat in London. For the same work, independent engineers quoted £2,000 and £2,300.

British Gas also quoted £5,106 for a new boiler in a five-bedroom house in Nottingham. However, two independent engineers found on Which? Local priced the work at £2,485 and £2,888.

And a Which? member in Manchester said that British Gas quoted £3,457 to replace a heat-only boiler with a modern condensing equivalent, while local contractors asked for just £1,700 and £1,940.

British Gas said: ‘It is difficult to provide a succinct comment, given that in all these circumstances British Gas were just one of a number of quotes the consumers explored and we didn’t actually install any of the boilers.’
