Free Home Insulation Services

HIGH ENERGY BILLS? – Reduce them now!

Free Insulation grants are available to install Cavity Wall Insulation, Internal Wall Insulation, Loft Insulation and Room in Roof Insulation. All UK householders, in receipt of a qualifying income-related benefit can qualify.

EnergyLink can also help with grants of up to 25% for External Wall Insulation. You do not currently need to be receiving benefits to qualify. External Wall Free Insulation is also available in the KW, IV and PH areas of Scotland, as long as the property is not on the gas network.

Home Insulation Grants do not have to be paid back. As long as you qualify, an approved and trusted Installer will complete the work then claim the grant to cover the cost of the work.

The grants are part of the Energy Companies Obligation (ECO). Under ECO, energy suppliers including British Gas, EDF, E.ON, Npower, Scottish Power, and SSE are obliged to pay for insulation in domestic households. They must improve the ability of low income, fuel poor and vulnerable people to heat their homes cost effectively. Insulation must result in heating savings, an important factor with increasing gas and electricity prices. ECO is a key policy in protecting those struggling to heat their homes.

Launched in 2022, ECO4 is the current Government-backed energy efficiency grant scheme, and will run until 2026. The aim of the scheme is to help reduce carbon emissions and tackle fuel poverty.

ECO4 focusses on low income and vulnerable, and fuel poor households whose properties have an EPC energy rating of D*, E, F or G. To support households on the lowest incomes, those in receipt of means tested benefits will be eligible. In addition, since 2023, The GREAT BRITISH INSULATION SCHEME (GBIS) targets households not in receipt of income-related benefits. Please see our Great British Insulation Scheme page for more information.

As long as you own or rent the property and it is currently occupied i.e. not under renovation, you should qualify for a Free Insulation Grant. If you do not qualify, we can still arrange for an approved Installer to provide you with a quote for the work.

Note – 100% grants are subject to a free, no-obligation survey. In most cases it is free but you may be asked to pay a small contribution, depending on the size and efficiency of the property.

Which Benefits Qualify For Free Insulation?

If someone living in the property receives one or more of the benefits listed below then you should qualify to have Cavity Wall Insulation, Internal Wall Insulation, Loft Insulation and Room in Roof Insulation installed completely free of charge:

  • Child Tax Credit
  • Housing Benefit (not the single person’s 25% Council Tax reduction)
  • Income-Based Jobseekers Allowance
  • Income-Related Employment Support Allowance
  • Income Support
  • Pension Credit Savings Credit
  • Pension Guarantee Credit
  • Universal Credit
  • Working Tax Credit

You may still qualify for free insulation if no one in your household is in receipt of a qualifying benefit, or if your annual household income £31,000 or less. You may even qualify under the Great British Insulation Scheme.

There are a number of schemes running and the criteria for funding is complex. EnergyLink will allocate you to a company who is able to calculate which scheme is most appropriate for you, to ensure that you’ll need to pay very little for the energy efficiency measures, or even to get it for free.

Even if you are not entitled to a 100% free insulation grant, EnergyLink can still put you in touch with an approved local Installer who can provide you with a quote.

Cavity Wall Insulation Grants

All householders in receipt of a qualifying benefit can claim a 100% free Cavity Wall Insulation Grant, as long as the property is occupied and not under renovation.

Properties built of brick between 1924 and 1982 are generally suitable for Cavity Wall Insulation, although we can help with properties that were built up to 2005 without insulation.

Please see our Cavity Wall Insulation page for more information.

Loft Insulation Grants

The property must be owned or rented, currently occupied and not under renovation. If you currently receive one or more of the benefits listed above, then you should be entitled to a 100% grant.

There must be 100mm (4 inches) or less of insulation already installed to qualify for a grant. This will typically be level with or below the joists. If it is above this level, we can arrange a free survey and quote to top up to 270mm.

How Much Money Can I Save?

Cavity Walls that have not been insulated can cause up to 35% of the heat in a property to be lost. Cavity Wall Insulation can typically save up to £145 per year on bills.

Solid Wall Insulation fitted internally or externally can save households up to £270 each year on bills and stop 1.8 tonnes of CO2 emissions.

Installing Loft Insulation can save you up to £150 per year on heating bills as it prevents up to 25% of heat being lost via the roof.

Having insulated roof rooms can also reduce heating bills by as much as £150 per year by preventing heat being lost through the walls and the roof.

How can EnergyLink help?

EnergyLink have a network of approved Surveyors and Installers working throughout England, Scotland and Wales. All have access to grants and can carry out a free, no-obligation survey.

Our form will tell you which grant you are likely to qualify for. Once you have entered your contact details, we will allocate you to an approved local Surveyor/Installer who will contact you to arrange a free, no-obligation survey.

If you are happy to proceed after the survey, a date will be booked for the installation. Following the work, the Installer will claim the grant amount you are entitled to. If you need to pay towards the work, this will be invoiced on completion.
