How ECO5 Funding Works

The ECO5 Scheme is entirely funded by the UK’s major energy suppliers as part of their obligation to support carbon reduction.

For eligible households, this means:

  • No upfront cost
  • No repayments
  • Work carried out by TrustMark-accredited installers

Funding levels are based on your home’s existing condition and the improvements needed to reach SAP targets. If you do not receive benefits, you may still qualify through Local Authority Flex (LA Flex).
