What is the ECO4 Scheme in the UK?
ECO4 is the fourth addition in the Energy Company Obligation (ECO) program, which began in 2023 and will end in March 2026. The scheme aims to fund low-income, fuel-poor, and vulnerable households to improve energy efficiency, reduce energy bills, and lower carbon footprints. The scheme has already installed around 3.6 million energy-efficient measures while improving more than 2.4 million houses in the UK.
The ECO4 scheme targets the least energy-efficient homes that cause high energy costs for the homeowners. Through these fundings, the homeowners can take big discounts on the insulation and green heating systems.
Up to now, the UK government has provided 4 billion pounds in funding to support home insulation, boiler, and heating upgrades.

Energy Efficient
ECO4 encourages insulated walls, which cut 35% of heat loss and help to keep the house warm and comfortable.
Carbon Control
By reducing 200,000 tons of carbon emissions, ECO4 has made homes more environmentally friendly.
Value boost
ECO4 makes homes energy-efficient, which sells fast with a significant increase in their value.
Enhanced Comfort
From chilly winters to hot summers, ECO4 upgrades keep your home perfectly comfortable for the whole year.
What is the GBIS scheme?
Another Funding scheme known as the Great British Insulation Scheme was launched in April 2023 to enhance the energy efficiency in Great Britain.
Managed by Ofgem, GBIS targets homes suffering from fuel poverty, high energy bills, and emitting CO2. This scheme treats these issues with efficient solutions like cavity, wall, and loft insulation.
Who can we apply?
- Homeowners, tenants(private or housing associations), or landlords can benefit from GBIS.
Having an EPC rating between D and G also makes you eligible for this scheme.
Homes included in Council Tax bands falling between A-D in England and A-E in Wales and Scotland.

Do I Still Qualify If I’m Receiving Government Benefits?
Yes, of course, receiving benefits already doesn’t restrict you from qualifying for the ECO4 scheme. It is designed to help:
If you have a critical EPC rating (D, E, F, or G), you are eligible to apply for the ECO4 program. This eligibility criterion shows the government’s commitment to efficient homes and healthy living.
Remember that eligibility criteria are not the same for everyone; it’s better to contact the company managing ECO4 to confirm the eligibility.
