Boiler Installation & Replacement in London

Current building regulations state that any replacement or new gas-fired boiler installation must be done with a condensing boiler. Older boilers convert as little as 60% of the fuel they use into heat which has a big impact on your home heating bills and the environment. While modern condensing boilers improve efficiency to over 90% which could save you a minimum of 30% per year on your home heating bills, representing a big saving over the lifetime of your gas boiler.

We specialise in the replacement and installation of condensing boilers and renewable energy products from all leading manufactures, such as Worcester Bosch and Vaillant, using the latest technology available. We provide an 8 year parts and labour warranty on selected Worcester Bosch boilers and 7 years on selected Vaillant boiler installations.

Greenserve are the first company in your area to be awarded the Worcester Bosch platinum accredited installer title. This proves we are dedicated to installing quality boilers and components.

Depending on your heating and hot water demand there are different types of condensing boilers that are available, don’t hesitate to contact us with any questions you might have regarding the replacement of your old gas boiler and the installation of a new condensing boiler in your home.
