Can I really get a free insulation grant?

Yes, insulation grants are available to eligible households under the government-backed ECO4  and Great British Insulation Schemes (formerly ECO+), with funding coming from the UK’s main energy providers.

The schemes 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. 

Eligibility is based on a number different criteria, with some on income-based benefits likely to qualify for ECO4 funding, while low EPC households in lower Council Tax bands may qualify for GBIS funding. 

Do I have to pay the grant back?

No, you do not have to pay anything back. As long as you are eligible under the terms of the relevant scheme, an installer will carry out the work and the grant will be used to cover the cost of the installation. Under the ECO and GBIS schemes, 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 of D, E, F or G and they are in a lower Council Tax property.

Helping you save up to £370 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 £370 once the loft or roof space has been insulated.

Did you know…

As much as 25% of heat loss in the home can be through an uninsulated loft or roof space.

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 – £370
  • Semi-detached house – £225
  • Mid-terrace house – £200
  • Detached bungalow – £360

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 April 2024.

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 – 620kg 
  • Mid-terrace house – 560kg
  • Detached bungalow – 1000kg

Who can qualify for a loft insulation grant?

Funding criteria differs for the GBIS and ECO4 schemes and so many more households are likely to be eligible for free funding. To qualify for loft insulation funding under the ECO scheme, you need to either own your home or privately rent it and have the landlord’s permission to make the necessary changes. 

If you meet the criteria, you should be eligible for a free grant that does not have to be paid back. Even if you are not entitled to a 100% grant, it is still worth enquiring as you could get a subsidy to save you money on your loft insulation.

There have been some changes to the ECO scheme meaning that some low-income households were previously excluded, as they didn’t receive benefits. Grants are also targeted at those homes that would most benefit from insulation and whose Energy Performance Certificate (EPC) puts them in the bands E, F or G.  

Social housing tenants should contact their council or housing association as they organise their own schemes to help improve energy efficiency in low-income households. If you own 50% or more of a housing association home, you can still apply for a grant.

Tanks and pipework are added on as part of the scheme, as well as fitting draught excluders around the hatch and a walkway to any tanks that are further than 1m from the hatch. Keep in mind that the insulation needs to cover 60% or more of the property. Extensions don’t usually qualify for grant funding for this reason.

Did you know…

The Climate Change Act has committed the UK to achieving net zero by 2050, compared to the previous target of an 80% reduction in emissions by 2050.

Qualify for free loft insulation?

Also, to qualify for free loft insulation under ECO4 , you need to be a household with an income of £31,000 or less, or someone in your household needs to be receiving one of the benefits listed below.

To qualify for free insulation under Great British Insulation Scheme funding you will need to be a low-income household, but not necessarily on benefits.

How can I apply for a free loft insulation grant? 

Applying for funding 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 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 to the costs.

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)

Alternatively you can visit Insulation Advisor to get an insulation quote.

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.

What different funding schemes are available for home insulation?

With multiple different funding opportunities available to you depending on where you live, there’s a good chance you could qualify for an insulation grant…

The £1 billion Great British Insulation Scheme (formerly known as ECO+)  is due to run until March 2026 and extends support to hundreds of thousands of households in energy inefficient homes in lower Council Tax bands, in an attempt to help some of the most vulnerable bring down their energy costs.

GB Insulation Scheme funding will help households who may not previously have been eligible for government support to upgrade the energy efficiency of their homes. The GBIS scheme builds on the existing £6.6 billion ‘Help to Heat’ energy schemes, including the Social Housing Decarbonisation Fund, Home Upgrade Grant and Local Authority Delivery Scheme.

Some of the main details of the GB Insulation Scheme are as follows:

  • Grants of up to £15,000 to eligible households
  • Will benefit households that do not currently benefit from government support to upgrade their home
  • 80% of the funding available for households who are in some of the least energy-efficient homes in the country
  • This includes homes with an EPC rating of D or below or those in the lower Council Tax bands.
  • Around 20% of the fund targeted to those who are the most vulnerable, including those on means tested benefits or in fuel poverty.

The Energy Company Obligation (ECO) scheme was introduced by the UK government in 2013 with the aim of reducing carbon emissions in domestic homes across the country. The scheme is now in its fourth iteration, ECO4, and obligates the large energy companies with the responsibility of supplying grants to qualifying households to cover the cost of energy efficient home improvements such as insulation.

By providing free grants for home insulation, those who are eligible can save hundreds of pounds on their energy bills, see improvements to the level of heat being retained in their properties, and they will become more environmentally friendly with lower carbon emissions. The latest and last version of the scheme, ECO4 was launched in autumn 2022.

Households in Scotland could take advantage of the available grant funding for home insulation through the Warmer Homes Scotland programme. This provides funding and financial assistance to homes that are considered most likely to be struggling with the cost of heating their homes. 

The scheme aims to help improve the energy efficiency of properties by covering the cost of installing a range of different home improvement measures, including insulation. The Scottish government grant is available to homeowners and private tenants who meet the eligibility criteria and have resided at the property for at least 12 months.

Read more about Warmer Home Scotland here.

The Welsh Government Warm Homes programme funds energy efficiency improvements and impartial advice to eligible households to help them receive free or substantially subsidised insulation to make their property more energy efficient.

Improvements are delivered through the Nest scheme, and had previously been through the Arbed scheme. The aim is to help fund energy efficient home improvements for low-income households and disadvantaged areas across the region to make their homes warmer and reduce energy bills.

Find out more about the Nest scheme Wales here.

The Green Homes Grant was created to fund eco-friendly installations to help UK households with the goal of reducing carbon emissions and to reduce their energy bills. The government established the voucher scheme, with these able to be redeemed for these energy-saving improvements, including insulation and low-carbon heating systems. The scheme was originally meant to run until March 2022, but was cancelled in March 2021.

The funding wasn’t limited to low-income households, but typically would have covered around two-thirds of the overall cost of any improvement, unless someone in the household received certain benefits, in which the full cost of the improvement would have been covered, up to a max of £10,000.

Various grants are available at a local level to help with the cost of insulating the home. The availability of grants will depend on the area you live in as there are different funding initiatives for insulation and other eco measures across the country.

Examples include London’s Warmer Homes Grant programme which provides grants of between £5,000 and £25,000 for free heating, insulation, and ventilation improvements for low-income households; Nottingham’s Healthy Housing Service funding a range of energy efficiency improvements for those over the age of 60, or families considered at risk due to cold-related illnesses; and York’s Home Upgrade Grant (HUG) that funds home improvements, including insulation and draught-proofing, for low-income households.

What types of insulation are covered by the schemes?

Insulation grants are available for  many different types of home insulation, providing you with the opportunity to get your home insulated for free, or at the fraction of the cost.

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 £485 each year (based on a detached property and fuel prices as of January 2024).

For more information visit our cavity wall insulation grants page. 

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.

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. 

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. 

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.

For more information visit our external wall insulation grants page.

Loft Insulation FAQs

Common  questions about loft insulation answered for 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 £225 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 £370 a year for a larger detached property because quality insulation can prevent up to 25% of heat from being lost through the roof. 

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

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.
