Is it possible to get free insulation?

Is it possible to get free insulation?

Adding or upgrading insulation is one of the best ways to improve energy efficiency and reduce costs. High upfront costs can be a major barrier, but there are grants and schemes available to help reduce these if your home qualifies.

Over time, the insulation will pay for itself through savings on your energy bills. It will also make your home cozier and put you in a good position if you ever decide to switch to a low carbon heating system. So it’s worth doing, especially if you can get a grant to help.

We’ve rounded up the schemes currently available offering free or cheaper insulation in England, Scotland, Wales and Northern Ireland.

Assess the energy efficiency of your home

Before you look for grants you may be eligible for, it’s worth assessing the current state of your home’s energy efficiency. Think about any insulation you may already have in your attic, roof, walls or floor.

You can use our home energy planning tool to speed up the process and keep track of the updates you make:

Other helpful things to do before searching for grants that will help you in your search and application:

  • Find and read your Energy Performance Certificate (EPC) rating
  • Find out your council tax band
  • Write down all government benefits you receive.

For more information on different types of insulation and how to interpret EPCs, read our guide to how to insulate your home.

Great British Lockdown Scheme

The Great British Insulation Scheme (GBIS) offers cheaper or free roof, loft, cavity or solid wall insulation.

This is the latest phase of the Energy Company Obligation (ECO) scheme, which requires energy suppliers to help households improve energy efficiency.

Eligible properties must have an energy efficiency rating of D or lower and be in council tax bands AD in England or AE in Scotland and Wales. GBIS is not available in Northern Ireland.

Homeowners, landlords or tenants can apply, but tenants will need to ask their landlord for permission before anything can be installed.

You can try out the tool to become eligible for the Great British Lockdown Scheme. on the government website. You can also call 0800 098 7950 or speak to your electricity supplier directly about this.

The tool will ask questions like how you heat your home, whether it has solid or cavity walls, and whether you get any benefits.

After using the tool, you will be referred to your energy supplier for further support.

For more information about the types of home improvements available and which energy suppliers are participating in the scheme, read our guide to Energy Company Obligations (ECO).
