Considering buying a British Gas boiler? Read the Which? essential guide to British Gas boilers - we reveal what you need to know.
British Gas is the UK's largest energy supplier and it also installs boilers. This includes the British Gas 330+ and the British Gas 5 series range of combi boilers, as well as those made by other brands including Baxi, Worcester Bosch and Glow-worm.
The British Gas 330+ heat-only boiler has a built-in energy use indicator, which enables you to monitor gas consumption and compare trends over a seven-day period. Unusually, it is a 'one-size-fits-all' boiler - it doesn't come in a range of different heat output 'sizes', and the installer sets how much heat it can give out. It was developed for British Gas by Glow-worm.
The British Gas 5 series range of combination boilers was developed by Worcester and comes in three different heat outputs. The British Gas Precision range was developed by Baxi.
