Grants For Insulation: A Guide To What’s Available 2022

Want to reduce your energy bills?

Improving your insulation is one of the best ways to achieve this, but what government grants are currently available to assist? Read on to find out more….

The cost of living is at its highest level in a decade, and home energy bills are one of the biggest contributors.

Approximately 22 million people saw their energy bills rise on April 1, 2022 after Ofgem announced a price cap increase of 54%. Some customers' bills have risen by £708 to more than £2,000 per year.

In October 2022, the price cap will be raised again, further compounding the problems.

If you want to lower your energy bills and reduce your carbon footprint, installing insulation and draught proofing are the most effective measures that will reduce heat loss and therefore save you money.

Grants are available to access finance for installing insulation across the UK, depending on your location and circumstances. Read our handy guide to find out what grants are available in your area.

Energy Company Obligation (ECO) Insulation Grants

ECO is the main national scheme for supporting energy efficiency improvements in low income and vulnerable households.

ECO is not a government grant; it’s an obligation placed on the large energy suppliers to assist in the installation of energy efficient measures such as improved insulation and more efficient heating.

There are many improvements that can help energy companies achieve their ECO goals, but in practice, most companies focus on cavity wall and loft insulation. It is also possible to get financial help when replacing an inefficient boiler or other heating system.

A list of measures can be seen below:

Loft Insulation

Cavity Wall Insulation

Upgrade from Single to Double Glazed Windows

Boiler Replacement

To qualify for ECO if you need to be eligible for benefits and meet specific requirements. However there are some specific situations where can access an ECO grant even if you are not claiming benefits.

The Energy Saving Trust has lots of useful information including energy saving tips.

UK insulation grants are constantly changing and new ones are likely to appear in the next few months as the government attempts to tackle the cost of living crisis. For an up-to-date source of information the UK government website is worth checking out before starting any energy saving projects.

The Green Homes Grant Local Authority Delivery Scheme

As well as national grants there are lots of local insulation grants available to access in England depending on your postcode.

Local authorities will provide homeowners, tenants and people in social housing with up to £10,000 in wall and attic insulation incentives if the home has an Energy Performance Certificate (EPC) rating of D or below and there is an annual combined gross income of less than £30,000 and have less than £16,000 in savings.

You may also be eligible if you do not have a current EPC or earn more than £30,000 a year but receive certain benefits.

To find out what grants are available in your area, for your circumstances, click here and enter your postcode.

If you and your property are eligible, the following energy efficient measures can be covered by the grants:

  • Insulation (solid wall insulation, loft insulation, cavity wall insulation, room in roof insulation and underfloor insulation)

  • Renewable heating technologies (air source heat pumps, solar PV and Solar thermal)

  • Energy efficient external doors and window upgrades (single glazed to double glazed)

If your house is currently heated by Gas Central Heating it is not eligible for the scheme so an application would be rejected.

No Grants Available?

If you cannot find any suitable insulation grants in your area, it is possible to install loft insulation and draught-proofing measures yourself. Both are relatively inexpensive projects and will provide immediate significant energy saving benefits.

Both projects will pay for themselves in a short amount of time.

For more information on installing loft insulation see our blog here. And the costs involved here.

Loft Insulation and Storage

If you manage to get an insulation grant, or you decide to fund the installation yourself, and it includes fitting loft insulation make sure once it’s installed you do not compress it.

Compressing insulation squeezes the air from the system and can reduce its thermal performance by up to 50%. The last thing you want to do is spend money insulating your loft to then reduce its effectiveness.

If you want to use, or continue to use, your loft for storage then adding Loft Legs will allow a storage platform to be created above the insulation.

Loft Legs simply screw into the ceiling joists or roof trusses enabling a raised boarded area to be created.

Find out more on creating storage in a loft above insulation here.
