Insulation is invaluable when it comes to helping your home feel warmer as well as lowering your energy bills. However, it can be costly to install, so it is always worth seeing if you can qualify for funding to cover the cost of installing insulation on your property. 

Certain energy companies will offer free spray foam insulation grants to help make your home more energy efficient and reduce carbon emissions, thanks to the government’s ECO (Energy Company Obligation) scheme. Below are some figures (according to the Energy Saving Trust and based on fuel prices as of October 2022) of how much money you potentially could save with insulation:

  • Loft insulation (270mm): £330-£590 a year
  • Floor insulation: £75-£180 a year
  • Cavity wall insulation: £235-£690 a year


The exact amount you could save will depend on the size and type of your home, as well as how energy efficient it already was. Over time, the insulation will give you a great return on investment with the savings you make on your heating bills, so it is certainly worth the initial spend. If you are looking for guidance with the upfront cost of insulation, read on to find out what help is available to you.

Are there spray foam insulation grant schemes running now?

The latest version of the ECO scheme, ECO4, is open to new applicants. If you meet the eligibility criteria you could access a spray foam insulation government grant through this scheme. Keep in mind there are some changes in the eligibility criteria from ECO3 to the new ECO4, so be sure to check your eligibility with us before starting an application for a free insulation grant.

Which energy suppliers are offering spray foam grants?

Large energy providers  – considered those with 150,000+ customers – are obligated to offer energy efficient home improvement grants as part of the ECO scheme. However, the number of measures they will fund comes down to their share of the market, meaning smaller energy companies will typically have limited availability. Suppliers that are obligated to provide funding for the scheme include the likes of British Gas, E.ON, EDF Energy, Scottish Power, SSE, and Ovo,  plus a number of medium-sized providers.

Free loft and cavity wall spray foam insulation

Loft and cavity wall insulation can take hundreds of pounds off your energy bills every year. Through the ECO scheme, you could get it installed for free, as long as you own your own home and meet the other eligibility criteria. However, you should ensure it is suitable for your home first.

What is loft and cavity wall insulation?

Loft insulation

Up to a quarter of the heat within your home escapes through the roof. Loft insulation can limit this by having mineral wool placed under the rafters.

Cavity wall insulation

The majority of houses built between 1920 and 1990 have a gap between the internal and external walls, this is called a cavity wall. By filling this gap with insulating material, you can keep the cold air out and the warm air in, but it is not suitable for every home.

Who is eligible for spray foam insulation grants?

It is likely you will qualify for a grant if:

  • You are a homeowner (or in certain cases, are a private renter) and
  • You or someone in your household is claiming certain eligible benefits. Some examples include universal credit, pension credit, income support, and more.

How can you apply for free spray foam insulation?

Before you think about applying for free insulation funding, you need to check whether you are eligible. If you get in touch with us we can help you determine your eligibility for the ECO scheme and put you in touch with experts that will handle the entire application process for you from start to finish.

Paying for insulation

If you do not qualify for a spray foam insulation government grant, how you pay for insulation installation will depend on your personal circumstances and the total cost of the work involved. You might be able to do small, simple insulating jobs yourself fairly inexpensively, like draught-proofing. Larger scale jobs that require a professional installer can cost upwards of around £345 for cavity wall insulation in a flat to roughly £7,400 for internal wall insulation.
