Insulation Installed

Save On Energy Bills

Can I really get a free insulation grant?

Yes, insulation grants are available to eligible households under the government-backed ECO4 scheme with funding coming from the UK’s main energy providers.

The scheme provides funding for households to help them improve the energy efficiency (EPC) of their homes, reduce their carbon footprint, and make savings on their heating bills.

Qualifying benefits include a number of income-based benefits, including Jobseekers Allowance and Income Support. However, there are several more ways you could be eligible for a grant without needing to be receiving benefits.

Do I have to pay the grant back?

No, you do not have to be pay anything back. As long as you are eligible under the terms of the scheme, an installer will carry out the work and the grant will be used to cover the cost of the installation. Under the ECO scheme the main energy suppliers, including British Gas, E.ON, Npower, Scottish Power, SSE, EDF plus others, have an obligation to provide the grants that pay for insulation in qualifying domestic households.

There have been some changes to eligibility, meaning that some people who were previously excluded, as they didn’t receive benefits may now qualify for a home insulation grant, especially if they are a low income household. Grants are also targeted at homes whose Energy Performance Certificate (EPC) puts them in the bands E, F or G.

How can I apply for a free loft insulation grant?

Applying is easy with our quick online form. Here is how you can apply for free loft insulation grant:

Find out whether you qualify or not by submitting an inquiry via our form. (You can check your EPC rating using the Gov.uk website if you reside in England or, you can use Scottish EPC Register if you reside in Scotland.)
Then a registered insulation installer will be in touch to arrange an appointment for a survey.
Assuming you are happy to proceed the work will then be scheduled at a time convenient for you.

The work will be completely free of charge if you receive certain income-related benefits, with the grant covering the entire cost of installing loft insulation. However, in certain cases, if the insulation installation is complex, then you may be required to make a small contribution.

Even if you do not qualify for a full house insulation grant it is still worth applying as you may be able to get a subsidised grant to partially cover the cost of your new insulation. You may also be able to claim a heat pump grant (see here) or a solar panel grant (see here).

By adding insulation to your home you will improve your energy efficiency, reduce your carbon footprint and reduce your energy bills. This allows low-income households to not only have the initial cost covered but to continue to save on their monthly bills.

You don’t need to be receiving benefits!

Helping you save up to £590 annually on your energy bills

Since insulation can make a significant difference in heat loss in the home, it has the potential to save you hundreds on your energy bills – particularly when the colder weather sets in! According to the Energy Saving Trust, an uninsulated detached property could enjoy annual energy bill savings of up to £590 once the loft or roof space has been insulated.

Annual savings that could be enjoyed by previously uninsulated properties having loft insulation installed for the first time have been estimated by the Energy Saving Trust as follows:

Detached house – £590
Semi-detached house – £355
Mid-terrace house – £330
Detached bungalow – £590

Estimated savings are based on insulating a gas-heated home with a totally uninsulated loft with 270mm of loft insulation and based on fuel prices as of October 2022.

The savings don’t just end there, as a typical loft insulation could also save many kilograms of CO2 emissions. Estimated annual savings (kgCO2/year) are as follows:

Detached house – 1000kg
Semi-detached house – 610kg
Mid-terrace house – 560kg
Detached bungalow – 1000kg

What types of insulation are covered by the schemes?

Cavity Wall Insulation

All private homeowners that are eligible can claim a cavity wall insulation grant, as long as the house is occupied and not having renovation work completed. Brick-built properties made between 1924-1982 are usually suitable for cavity wall insulation, although properties that were built up to 2005 without insulation can also receive help.

With energy costs rising year on year, cavity wall insulation is one of the best ways to reduce your heating bills. Research has shown that un-insulated cavity walls can cause up to 35% of the heat within a property to escape, and homes with cavity wall insulation can save up to £690 each year (based on a detached property and fuel prices as of October 2022).

For more information visit our cavity wall insulation grants page.

Loft insulation

To be eligible, the house must be owned or privately rented and currently occupied. If you are getting one of the benefits listed above, you should be entitled to a grant to cover the cost of loft insulation.

In order to qualify for loft insulation grants, the property should be uninsulated or have loft insulation of 100mm or less. Usually, this will be level with or below the joists. If it is over this level, you could have a survey and a quote to top up your insulation to 270mm.

Room in roof insulation

If you are receiving one of the qualifying benefits and you are the homeowner or private tenant, you should be able to get free room in roof insulation. To be able to have this type of insulation put in place, the home needs to have roof rooms from when it was first built or have undergone a loft conversion. There should be minimal or no insulation in the walls and ceiling and the property must have a fixed staircase to access the loft.

For more information visit our room in roof insulation grants page.

Internal wall insulation

If someone in your household is claiming a benefit, you might be entitled to free internal wall insulation for your home, if you are the owner of the property or are renting it from a private landlord. The building must have walls that are of solid construction type for you to be able to have internal solid wall insulation put in.

For more information visit our internal wall insulation grants page.

External wall insulation

For an external wall insulation grant, you can claim up to 25% of the cost. Prices for installing external wall insulation can normally range from £7,000 to £15,000. It is usually installed in properties that have solid brick or concrete walls, but it can also be fitted to homes with cavity walls that are not suitable for cavity wall insulation.

Loft Insulation FAQs

How Much Money Does Loft Insulation Save You?

One of the biggest benefits of having the full recommended levels of loft insulation installed is the cost-saving it can offer to homeowners each year.

Whilst the exact amount of money you can save if you install loft insulation in your home will vary based on factors such as the type of insulation used and the size of your property, you can expect to save at least £330 a year on energy costs (assuming your loft was previously uninsulated).

Depending on the size of your home, those with lots of heat lost through the roof can expect to save even more, in the region of up to £590 a year for a larger detached property because quality insulation can prevent up to 25% of heat from being lost through the roof.

How Long Does Loft Insulation Last?

If installed correctly, loft installation should last around 40 years before it is likely to need replacing.

How Long Does Loft Insulation Take to Install?

For an average size loft, it can take 1-1.5 hours to complete a loft insulation fitting. Your loft will need to be free of clutter so that our installers can have easy access to complete the installation.
