Welcome to 
Green Heat Coop

Building community and supporting efficient, low carbon home heating in and around North Herts

Gas and oil heating for homes is the largest single contributor to carbon emissions in North Hertfordshire, making up nearly one quarter of our region's emissions (BEIS, 2020)


Green Heat Coop is a non-profit, co-operative company focused on the transition away from fossil-fuels to high efficiency, low carbon, high comfort home heating systems.  We offer a local and personalised approach to support householders through this change.  We can help you understand and navigate the options for your home, including heat pumps and energy efficiency measures.


We are based in Royston and serve Herts, Cambs, and surrounding areas. We are keen to have the involvement of residents, heating engineers, and building professionals.
