ECO Flex for suppliers

You may be able to get free or low‑cost insulation or heating improvements through the ECO4 Scheme or the Great British Insulation Scheme. These UK Government schemes help people on low incomes or in hard‑to‑heat homes stay warm, reduce energy bills and improve comfort. 

What the schemes offer

ECO4 Scheme

ECO4 is a government scheme that requires energy suppliers to fund energy efficiency improvements in homes that need them most. It mainly helps households who are on a low income or who may be affected by living in a cold home.

ECO4 often provides more than one improvement, such as insulation and heating upgrades, to make homes warmer and cheaper to heat.

Great British Insulation Scheme

The Great British Insulation Scheme focuses on improving homes with poor energy ratings. It usually provides single insulation measures, such as loft or wall insulation, to help lower energy bills.

ECO4 Flex and GBIS Flex

Some households do not meet the standard rules for these schemes but still need help. ECO4 Flex and GBIS Flex allow us to confirm eligibility for extra households, such as people on a low income or with health conditions made worse by cold homes.

We only confirm whether you meet the eligibility rules. The energy supplier decides:

• whether work goes ahead
• what measures are installed

Any work must improve your home’s energy performance certificate rating.
