Eligibility Criteria for Government Insulation Grants
Government insulation grants are designed to help UK residents improve their home’s energy efficiency. Here’s what you need to know about qualifying for these energy efficiency grants:
Great British Insulation Scheme (GBIS)
The Great British Insulation Scheme is a government initiative running from April 2023 to April 2026. It aims to improve energy efficiency in homes across Great Britain, focusing on low-income and vulnerable households.
Key features:
-
Targets properties with EPC ratings of D to G
-
Eligible for homes in Council Tax bands A to D in England and A to E in Scotland and Wales
-
Unlike ECO4’s “whole house” approach, GBIS focuses on single insulation measures such as loft insulation, cavity wall insulation, or solid wall insulation.
-
Can subsidise up to 75-100% of insulation costs for eligible households
Energy Company Obligation (ECO4)
ECO4 is the latest phase of the Energy Company Obligation scheme, running from April 1, 2022, to March 31, 2026. It places obligations on medium and large energy suppliers to promote energy-saving measures.
Key points:

-
Originally built with roof rooms or the loft has been converted
-
Minimal or no existing insulation is present
-
A fixed staircase leads to the room(s), rather than a pull-down loft ladder
For more information on this type of insulation and to see if your property qualifies, visit our Room in Roof Insulation page.
External and Internal Wall Insulation
External and Internal Wall Insulation grants are typically available for:
-
Properties with solid walls or system-built constructions that lack a cavity
-
May be considered for cavity wall properties if cavity wall insulation is not possible or practical
-
Grants covering up to 25% of the cost of external wall insulation may be available regardless of income or benefits
For more details on how these insulation types can improve your home’s energy efficiency, see our External Wall Insulation and Internal Wall Insulation pages.
Regional Variations
While most government insulation grant schemes are available across the UK, there are some regional differences to consider:
-
Council Tax band eligibility: A-D in England, A-E in Scotland and Wales
-
Northern Ireland has separate grant options; residents should consult local authorities
-
Western regions of England, Wales, and Scotland may have restrictions on cavity wall insulation due to exposure to wind-driven rain
-
Local councils may offer additional or alternative insulation schemes
Additional Considerations for Insulation Grants
Vulnerable Groups
Pensioners over 70 are classified as a “Priority Group” under most insulation grant schemes and receive preferential treatment in grant allocation. They can qualify for insulation grants through the Low Income Group or General Group criteria. For tenants aged 70 or over, or those whose main income is the state pension, they are likely to receive free insulation without any contribution.
Households with members suffering from health conditions exacerbated by cold homes may also qualify for grants without meeting income-based criteria. Qualifying health conditions include cardiovascular diseases, respiratory diseases like asthma or COPD, limited mobility conditions such as arthritis, and immunosuppression due to cancer treatment or autoimmune diseases.
Mental health conditions like severe anxiety, depression, or chronic fatigue syndrome can also qualify.
To demonstrate eligibility based on a health condition, applicants may be asked to provide one or more of the following:
-
A letter from a General Practitioner (GP) or other healthcare professional: This letter should confirm the diagnosis of a relevant health condition and state how the condition is negatively impacted by cold or damp living conditions.
-
A copy of a prescription: A recent prescription for medication related to a qualifying health condition can serve as evidence.
-
A discharge summary from a hospital stay: If the individual has recently been hospitalized due to a health condition exacerbated by cold weather, the discharge summary may be used as proof.
-
A care plan from a social worker or healthcare provider: A care plan outlining the individual’s health needs and how they are affected by their living environment can be submitted.
-
A disability living allowance or personal independence payment award letter: Receipt of these benefits can be used as evidence of a long-term health condition or disability.
Eligibility can be obtained through GP referrals or assessments by health boards. A medical assessment by an NHS GP can determine eligibility under the medical condition route for ECO4 grants.
Landlord Permissions for Private Renters
Private renters require landlord approval before applying for insulation grants. Landlords are encouraged to participate as it improves property value and tenant satisfaction. Tenants can apply on behalf of landlords for insulation grants, but landlords must provide written permission for the work to be carried out.
For single property rentals, landlords can complete the application form themselves with tenant information. For multiple properties, landlords can contact grant providers for assistance with applications on behalf of multiple tenants. In England and Wales, landlords cannot let properties with an EPC rating below E unless they have a valid exemption.
If a landlord refuses permission for insulation upgrades, the tenant, unfortunately, cannot proceed with the grant application under the current schemes. Tenants may wish to discuss the benefits of energy efficiency upgrades with their landlord, highlighting potential increases in property value, improved tenant satisfaction, and compliance with minimum EPC requirements.
What are the Benefits of Insulation Grants?
Insulation grants offer numerous benefits to homeowners and tenants, enhancing both financial savings and environmental sustainability.
Cost Savings
Insulation grants can significantly reduce energy bills by preventing heat loss from homes. For example:
-
Loft insulation can save up to £270 annually for a semi-detached house.
-
Detached houses can save up to £445 per year with proper loft insulation.
-
Cavity wall insulation can result in savings of up to £300 annually.
-
Overall, households could save between £630 to £730 per year on energy bills with comprehensive insulation measures.
These savings are particularly impactful given the rising energy costs in recent years. With a potential payback period of just a few years, energy efficiency insulation grants provide a cost-effective solution for improving home energy efficiency.
Environmental Impact
Insulation grants contribute significantly to reducing carbon emissions and improving overall energy efficiency:
-
Proper insulation can reduce a home’s carbon footprint by approximately 1.7 tonnes of CO2 emissions annually.
-
The Great British Insulation Scheme (GBIS) aims to retrofit 300,000 homes by March 2026, significantly reducing the UK’s overall carbon emissions.
-
Insulation plays a crucial role in the UK’s journey towards achieving its Net Zero by 2050 goal.
Additional Benefits
Beyond cost savings and environmental impact, insulation grants offer several other advantages:
-
Improved home comfort by reducing drafts and maintaining consistent temperatures.
-
Enhanced property value due to improved energy efficiency ratings.
-
Healthier living environments by reducing dampness and mold growth.
-
Support for vulnerable groups, including pensioners and those with health conditions exacerbated by cold homes.
With the upcoming Warm Homes Plan set to launch in spring 2025, even more comprehensive support for home energy efficiency improvements is on the horizon, further enhancing the benefits of insulation grants for UK households
