MCS Charitable Foundation is an independent UK-wide charity. Our mission is to accelerate the widespread adoption of renewable energy and low-carbon technologies.

We look to fund retrofit-related projects as defined as energy efficiency or renewable generation measures to a domestic building. This is in line with our objective to make every UK home carbon free.

The maximum grant available for 2025 was £50,000 inclusive of VAT. A total funding pot of £300,000 was available and we therefore expect to be funding around six grants, if the maximum amount of funding is requested.

Projects will need to be one or both of the following types:

• Retrofit in action: projects demonstrating or experimenting with methodologies in the real world and actively evaluating results

• Retrofit research: research projects which aim to research a particular issue and better inform retrofit work in the future

Building on the Foundation’s knowledge of the sector and stakeholder consultation we are particularly interested in grants responding to one or more of the following questions:

1. What are effective grant and finance mechanisms to deliver measures?
2. How do we engage citizens in retrofit and then turn engagement into action?
3. How do we increase the numbers of people entering the retrofit supply chain?

The MCS Foundation may provide feedback on project ideas via email in the first instance. We can’t guarantee to provide feedback but will do our best to do so. Please provide us with a concise overview of the project idea and benefit.
