Our mission is to change the nature of energy ownership in the UK and put people at the heart of it. We are majority owned by the community energy groups we work with.

Mongoose brings together local people and commercial developers to identify, develop, finance, build and manage community-owned, clean energy projects.

Project development

We provide the specialist expertise community energy groups need to bring renewable assets like solar parks and wind farms into community ownership.

Community partners

We work with community groups around the United Kingdom who are making clean energy projects happen. New and established groups are welcome to join us.


From wind and solar to biogas and hydro, there are thousands of community power projects popping up all around the world. In the UK alone there are more than 600 community-owned renewable energy projects and that number is growing.
