Boiler brands rated British Gas
UK-based British Gas is the UK's largest energy supplier, and also installs boilers. As well as installing branded boilers, it sells its own models, including the British Gas 330+ and the British Gas 5 series range of combi boilers.
British Gas gas boiler range
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, how much heat it can give out is set by the installer, so it doesn't come in a range of different heat output 'sizes'. It was developed for British Gas by Glow-worm.
The 5 series range of combination boilers was developed by Worcester and comes in three different heat outputs. The British Gas Precision range was developed with Potterton.
