Understand more about Worcester boilers:
Worcester Greenstar condensing boilers are highly efficient, offering significant savings on fuel bills and the environment.
Which boiler do I need?
The easiest way to find out which boiler is best for you is to use our Find a Boiler search.
Householders who have had their existing boiler for more than 10 years and receive high gas and oil bills, could save up to £225* a year by upgrading to a condensing boiler.
Older boilers can be as little as 60% efficient. Every Worcester Greenstar boiler is designed to be highly efficient - they turn more of the fuel they use into heat and hot water for your home.
Which? Best Buy accreditation
In the 2014/15 report and for the fourth year running the entire range of Worcester Greenstar gas boilers have been awarded Which? Best Buy, the only boiler manufacturer to have been awarded Best Buy status*
