- Priority given to vulnerable residents

How to Apply
The application process varies by scheme. For the Boiler Upgrade Scheme, your MCS-certified installer applies on your behalf. For ECO4, contact your energy supplier directly or use a scheme administrator. Local authority grants are applied for through your council.
Tips for Maximising Your Grant
- Get an up-to-date EPC (Energy Performance Certificate) — many schemes require one
- Check all schemes you might qualify for — some can be combined
- Use an MCS-certified installer for BUS applications
- Apply before getting the work done — most grants cannot be claimed retrospectively
- Keep all paperwork and certificates from the installation
