The MCS Foundation Main Grant Call is now open for 2026. The closing date is midday on Tuesday 31st March. The maximum grant available is £50,000 inclusive of VAT.  

We are looking to fund projects that have a close strategic fit to our mission:  

‘To transform the way our homes are heated, cooled and powered by reducing carbon and increasing electrification, energy efficiency and affordability.’  

Our vision is that every UK home benefits from being carbon free.  

In particular we are looking for applications which address one of our four themes, however applications outside of these themes which still work towards our vision are welcome. 

The four themes are:

• The role of heat pump system efficiency and flexibility
• How to better utilise data
• Ways to support commissioning organisations to deliver low carbon heating
• How to use comfort as a driver for retrofit demand
