If your home loses heat quickly, poor insulation could be one reason. Insulation Grants UK schemes may help with the cost of improving your home in 2026. The options are not the same for everyone. Your postcode, property and the funding available in your area will affect what help you can get.
Some government-backed and local schemes may help cover work such as loft, cavity wall or solid wall insulation. Not every home or household will qualify, and funding may be limited.
This guide explains who may be eligible, which work may be covered, and how to check the rules and apply. Always check with the scheme provider before work starts.
An insulation grant helps pay for approved work to keep a home warm. Some schemes cover the full cost, while others pay only part of it. Insulation Grants may help eligible households improve their homes, but each scheme has its own rules.
Home Insulation Grants can help pay for work that keeps heat inside your home. This can help you reduce heat loss, keep rooms warm and use less energy for heating.
Before work starts, your home may need a check. This helps show which type of insulation is suitable. Meeting the grant rules does not mean every type of work will be approved. The final decision depends on the scheme and your property.
Grant rules vary across the UK. To qualify, your home and household must meet the rules of a scheme in your area.
Your home’s Energy Performance Certificate (EPC) may matter. Some schemes focus on homes rated D to G. Wall type and the heating system can affect which work is suitable.
Homeowners and private tenants may qualify, but the rules vary. Your postcode can also matter, as some councils only fund homes in set areas. For example, England’s Warm Homes: Local Grant has its own EPC and property rules.
Yes. Some schemes help people on a low income or those who get certain benefits. Under England’s Warm Homes: Local Grant, household income is usually £36,000 a year or less. Some homes may also qualify through a set postcode or benefit route.
These rules do not apply to every grant, and getting a benefit does not ensure approval. You may need proof of your income or benefits. If you rent, ask your landlord for permission and check whether they must pay part of the cost. A home check may also be needed before work is approved.
Funding depends on your home’s design, condition and the scheme’s rules. Not every grant covers every type of insulation.
Solid walls have no gap between inner and outer layers. Solid wall insulation grants may help eligible homes add insulation inside or outside these walls. Both methods can help to reduce heat loss.
Internal insulation is done inside the building, such as in rooms and may require sockets and radiators to be moved.
External insulation changes the building’s outside. So it looks different, and planning rules may matter. Before work starts, a qualified surveyor should check for damp, wall damage and ventilation needs. The right option depends on the home and scheme.
Loft insulation slows heat loss through the roof. Cavity wall insulation fills a suitable gap between wall layers. Underfloor insulation helps reduce heat loss through floors.
A survey can show which option suits your home. Check that the grant covers the work before installation begins.
The insulation grants UK options depend on where you live, your home and whether a scheme is taking applications. Check the rules before you apply.

Use this checklist:
Get the terms in writing before work begins. Ask questions if anything is unclear.
