Information for suppliers and contractors

We have appointed Happy Energy Solutions Ltd (HESL) as our Managing Agent for ECO4 and GBIS Flex.

Only declarations submitted to and by HESL can be considered for funding. No declaration requests made directly to Essex County Council, by suppliers and contractors, will be accepted.

All interested suppliers must be onboarded with HESL before declarations can be made. Fees will apply. For full details of the onboarding process, visit the Heat Flex website.
