About Kensa

The UK’s heating system is outdated, costing both people and the planet too much. At Kensa, we’ve been leading the charge since 1999, manufacturing and installing affordable, green heating solutions with minimal impact on the electricity grid. We’re responsible for over half the ground source heat pumps installed in the UK. Our networked heat pumps are the cheapest, cleanest way to heat and cool millions of homes and businesses, and even entire towns. By 2040, up to 8,000 homes a week could be connecting to these heat networks, eliminating 17Mt of CO2 a year, equivalent to that of over half of all UK flights. In leading the networked heat pump sector, Kensa will expand to install 50,000 heat pumps a year and employ 1,500. It’s time to leave high bills and emissions behind.

We’re making heating better - for people, for the planet, and for the future.
