Government insulation grants are government schemes designed to provide homeowners or renters with financial assistance to increase the energy efficiency of their homes by installing insulation.
Due to the cost of living crisis, there is currently a great deal of financial assistance available, as well as ongoing assistance for those receiving benefits. Hundreds of millions of pounds are available to improve your home’s energy efficiency or help you pay your energy bills.
Knowing where to search is vital. This post will explain all the available government grants in the UK.
What insulation grants are available from the government?
There are several grants running that can provide financial assistance to homeowners who wish to install insulation:
- The Energy Company Obligation scheme (ECO4)
- Warm Homes Scotland
- LA Flex
- Nest (Wales)
- The Great British Insulation Scheme (closed on 31 March 2026)
Each of these schemes targets low-income and vulnerable households, which would gain the most from this financial assistance. Government insulation schemes can help low-income families improve home and energy efficiency.
What is the ECO4 scheme?
The Energy Company Obligation, or ECO4, is a government-supported energy efficiency scheme in the UK. This scheme seeks to reduce carbon emissions and combat fuel poverty by funding energy-efficient home improvements.
You may be eligible for a government insulation grant if you receive at least one of the following means tested benefits:
- Income based job seekers allowance
- Income related employment and support allowance
- Income support
- Pension credit guarantee credit
- Working tax credit
- Child tax credit
- Universal Credit
- Housing benefit

Nest scheme
People in Wales who meet specific conditions can install loft insulation through the government’s Nest scheme. Nest assists low-income and vulnerable individuals in Wales by providing financing for various home modifications and free, unbiased energy advice.

The Great British Insulation Scheme
The Great British Insulation Scheme, a new multibillion-pound energy efficiency scheme, has been the subject of research.
The Great British Insulation Scheme targeted the able-to-pay sector, focusing on people who could afford to increase the energy efficiency of their homes and were interested in contributing to these improvements.
It used many of the existing ECO administrative and delivery systems, but with partial household funding. The scheme began in April 2023 and closed on 31 March 2026.

The Warm Home Discount Scheme could save you £150 on your electricity bill from 2023 to 2024.

If you are eligible, you will usually receive the discount automatically.
Households can receive grants of up to 25% for installing external wall insulation, regardless of their income or eligibility for government assistance.
