Lower your energy bills with free, government-backed, insulation upgrades.

Is your home hard to heat or losing warmth too quickly? The Great British Insulation Scheme (GBIS) could be the solution.

This government-backed scheme helps households across Britain reduce their energy bills with free insulation upgrades — including loft, cavity wall, and solid wall insulation — installed by trusted professionals.

Even if you don’t qualify for other support schemes, GBIS may still be available to you. With funding open now and available for a limited time, it’s the perfect opportunity to make your home warmer, greener, and more affordable to run.

The Great British Insulation Scheme (GBIS) is a government-backed programme designed to help households cut their energy bills by improving home insulation. It offers free upgrades to homes that are under-insulated or harder to heat.

You could receive support for:
Loft insulation
Cavity wall insulation
Solid wall insulation
Room-in-roof insulation

The scheme places a legal obligation on large energy suppliers to fund energy-saving home improvements for qualifying households. That means real upgrades, real savings, and real comfort, at no cost to you.

GBIS is designed to help households that are struggling with high energy costs, inefficient homes or low incomes. You could be eligible if:

Someone in your home receives a means-tested benefit (like Universal Credit or Pension Credit)
Your total household income is under £31,000 per year
Someone living in the property has a qualifying health condition
Your home has a low EPC rating (E, F or G — or D if it’s a solid wall property)

The scheme is open to homeowners and private tenants (with landlord permission). We’ll handle all checks and paperwork for you.

Am I eligible for ECO4 funding?

You might be eligible if:

Your home has an EPC rating of D, E, F, or G
You receive income-related benefits (e.g. low income, certain health issues, or household vulnerability). Not sure? Our eligibility checker makes it easy to find out.

What kind of upgrades could I get?

Depending on your home, you could receive:

Solar panels to reduce electricity bills
A new, efficient heating system
Wall, loft or cavity insulation
Smart controls and upgraded radiators

The exact improvements you get are tailored to your home’s needs and usually include a combination of upgrades, determined by the survey.

Is the ECO4 scheme backed by the government?

Yes. ECO4 is backed by the UK government through the Energy Company Obligation (ECO) programme. Funding comes from energy suppliers, but it's a government-led initiative that helps households improve energy efficiency and lower their energy bills. The government-backed ECO4 scheme has supported thousands of eligible households to install energy-saving upgrades such as insulation, boiler replacements, heat pumps, and solar panels.

Do I have to pay anything?

No. If you're eligible, the scheme covers 100% of the cost, including surveys, installation and equipment.

How long does it take?

Once approved, installations can typically happen within 4-6 weeks, depending on your home, location and installation recommendations.

I rent my home, can I still apply?

Yes! If you’re a tenant in a privately rented home, you can qualify. You just need to get your landlord’s permission before work begins.

Will this affect my benefits?

No. Getting ECO4 improvements doesn’t impact your benefits in any way.

How do I know if I have an EPC?

You can check your EPC rating here. If you don’t have one, we can address it as part of your application.
