ECO4 and GBIS help UK homes become more energy efficient. ECO4 is a government scheme that gives free upgrades like insulation and heat pumps to low-income families. GBIS, or Great British Insulation Scheme, focuses on adding insulation to save energy and cut bills. Both programs aim to lower carbon emissions and make homes warmer, cheaper to heat, and better for the environment.
What is ECO4?
ECO4 stands for the Energy Company Obligation, Phase 4. It’s the latest version of a long-running government program designed to enhance energy efficiency in homes across England, Scotland, and Wales. ECO4 started in July 2022 and is set to run until March 2026.
The Key Goals of ECO4:
-
Help low-income and vulnerable households
-
Improve the energy efficiency of the UK’s least energy-efficient homes (especially those rated EPC E, F, or G)
-
Support the UK’s net-zero carbon emissions target
What Does ECO4 Offer?
Eligible households can receive free or subsidised home improvements, including:
-
Loft insulation
-
Cavity wall insulation
-
Solid wall insulation
-
Heating upgrades (like new heat pumps or efficient boilers)
-
Solar panels in some cases
The aim is to make homes warmer, more affordable to run, and better for the planet.
What is the Great British Insulation Scheme?
Formerly known as ECO+ during its consultation phase, the Great British Insulation Scheme was launched in 2023. While ECO4 targets low-income households, GBIS casts a wider net, helping more people reduce energy waste. The solar industry is rapidly growing with support from ECO4 and GBIS, helping homeowners access sustainable energy solutions.
The Main Features of GBIS:
-
Focuses primarily on insulation measures
-
Available to households in council tax bands A–D in England, and A–E in Scotland and Wales
-
Includes people who aren’t on means-tested benefits, expanding access beyond ECO4
Types of Insulation Covered:
-
Loft insulation
-
Cavity wall insulation
-
Solid wall insulation (internal or external)
-
Floor insulation (in some cases)
GBIS is about quick wins: simple measures that can have a big impact on reducing energy use and cutting costs.
How Do I Know If I’m Eligible?
ECO4 prioritises:
-
Households receiving means-tested benefits
-
Properties with poor energy performance
-
Social housing and privately rented homes (with landlord consent)
GBIS eligibility is broader:
-
Homeowners or private renters in eligible council tax bands
-
No need to be on benefits (though low-income households are still prioritised)

Lower energy bills, especially in the face of rising prices
-
Reduced carbon emissions, which support climate goals
-
Creating greener, healthier living spaces
Plus, insulation is often one of the most cost-effective ways to make a lasting difference.
