Originally founded in 1962, Worcester became part of the Worldwide Bosch Group in 1996 and we are the UK market leader in domestic boilers.
Our current product range includes gas and oil boilers, hot water cylinders, renewable technologies such as heat pumps and solar water heating systems, as well as controls and accessories.
Our commitment to the highest standards of manufacturing over the last 50 years, has led to us being consistently being recommended by Which? for both our gas and oil boiler ranges, and for Worcester to receive a Royal Warrant for supplying our boilers to Her Majesty The Queen’s Sandringham Estate.
The Worcester Bosch Greenstar 4000 is perfect for small to medium sized homes with one bathroom, it features a modern new design, an easy to use full colour text display and it’s quiet too. The Greenstar 4000 has a wide power range to meet all of your heating and hot water needs, whilst doing so efficiently.
* Up to a 10 Year guarantee when installed by a Worcester Accredited Installer. Terms and conditions apply.
Our entire gas boiler range is able to run on a 20% hydrogen blend – so you can be confident it will run on gas for it’s lifetime.
