Overview
The Energy Company Obligation (ECO4) and Great British Insulation Scheme (GBIS) are government energy efficiency schemes run by Ofgem.
They are both four-year schemes and are intended to run from 01 April 2022 to 31 March 2026.
The main aim of these schemes is to support low income and vulnerable households to:
- install energy saving measures
- improve the efficiency of the lowest rated homes
This is to help the government’s fuel poverty and net zero commitments.
Participating local authorities can refer households they consider to be:
- living in fuel poverty
- on a low income
- vulnerable to the effects of living in a cold home
