Cambridge Retrofit

CAMBRIDGE RETROFIT was a landmark community-scale energy efficiency initiative to retrofit buildings over the next 30 years, helping make the Cambridge area the first to reach national (UK) carbon reduction targets, reduce energy bills and improve the quality of our buildings. It ended in 2017 as a formal project and organisation. However, its resources and methods live on in a new set of activities we call Project Cambridge, and more specifically Project Cambridgeshire.

This Project Cambridge website (with black bars at top on all of its pages) contains the archived materials from Cambridge Retrofit as it developed between 2012 and 2017. The Cambridge Retrofit programme and organisation is now out of operation, although activities continue through ambitious projects of Cambridge City Council, Cambridgeshire County Council, the University of Cambridge and other community organisations that were so crucial in supporting Cambridge Retrofit. These materials show how Cambridge Retrofit was organised, administered and supported.

Through our network of businesses, estate firms, building owners, local authorities, financiers, academics, national government, contractors and tenants, we mobilised the aspirations and resources of the entire community, stimulating and facilitating suites of retrofit projects. This drives down costs, attracts finance and ensures we keep to our ambitious timetable. Our projects focused on all aspects of energy in buildings from thermal envelopes to energy supply to lighting to plug load, and can be linked to more general refurbishments aimed at improving the quality, value and comfort of buildings.

Cambridge Retrofit was one of three programmes working to reduce the carbon footprint of the city and surrounding county. Together, they covered the range of public and private sector organisations, and retrofits and low carbon energy production.


Cambridge Retrofit as a programme and organisation ended formally in 2017. However, interest remains high in continuing many of the resources and activities that we had put in place, especially with the declaration of climate emergencies by local groups in Cambridgeshire. Therefore CCR are joining with these groups to once again support ambitious community-scale carbon reduction projects in the city and surrounding towns and villages.

Go to the new effort we call Project Cambridgshire. This link will take you to the part of the site we call Taking Action (Go for the Gold). Before you do that, be sure the explore the other parts of this website to lay a foundation for understanding what you will be asked to do in Taking Action.

This website explains the process followed in creating Cambridge Retrofit, provides the data and tools needed to assess targets, identify the most effective retrofit strategies and monitor progress, and to mobilise people and organisations to work together in delivering a low carbon future for the Cambridge area. You can explore these lessons through the navigation bar at the top of the page.

Now for a travel break. This picture is of our home in Cambridge, on Portugal Place (ours was the first home you see on the right). The building was begun in the 17th century, and is in a historic conservation district, so making changes requires a long process of approval by City Council. But even such an old home is able to be given a significant retrofit.
