Insulation Grant Criteria

The two main considerations are whether the householder is likely to qualify for an Insulation grant and also whether the property is suitable to have insulation installed.

Grants to cover the entire cost are available to householders receiving income-related benefits or tax credits. You must also own the property or rent it from a private landlord.

Council or Housing Association tenants may be entitled to grant assistance providing they own half or more of the property.

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.

Who qualifies for an Insulation Grant?

Cavity Wall and Loft Insulation are generally free of charge to anyone in receipt of a qualifying income benefit or tax credits.

Roof Room and Internal Wall Insulation are also free to people receiving benefits.

Grants of up to 25% can be claimed towards the cost of installing External Wall Insulation, regardless of income or benefits.

The property must also be privately owned/rented, occupied at the time of the survey and there must be a gas or electricity bill in the occupier’s name.

Benefit Criteria

To qualify for free cavity, internal wall, loft or roof room insulation, someone living in the property needs to be in receipt of at least one of the benefits listed below:

  • 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
  • Child Benefit *

* Household income limits apply. See table below.

You could also qualify for grant funding if your gross annual household income is £31,000 or less.

Child Benefit Income Limits

If you are applying for a grant and using Child Benefit as the qualifying benefit, your income from all sources (before tax) must not exceed the limits shown below.  The amounts vary depending on whether you are a single claimant or part of a couple and the number of children for whom you are responsible.

Child Benefit Claim Type Income
Single & 1 Child £19,900
Single & 2 Children £24,800
Single & 3 Children £29,600
Single & 4+ Children £34,500
Couple & 1 Child £27,500
Couple & 2 Children £32,300
Couple & 3 Children £37,200
Couple & 4+ Children £42,000

What types of property qualify?

To qualify for a Cavity Wall Insulation grant, it may sound obvious but the property must have cavity walls. Typically, it will be brick-built and constructed between 1924 and 1982. Before 1924 it will more likely be solid brick and after 1982 it should already be insulated. However, we can help with uninsulated properties built up to 2005. See our Cavity Wall Insulation page for more details.

Loft Insulation Grants are for blankets of insulation laid on the floor of a loft. As long as you have a loft that is accessible and has less than 100mm of material already fitted then you should be entitled to a grant to have it insulated to a depth of 270mm. Visit our Loft Insulation page for further information.

You can apply for a Room in Roof insulation grant if the property was originally built with roof rooms or the loft has been converted. As long as there is minimal or no insulation present and there is a fixed staircase leading to the room(s), and not a pull-down loft ladder or similar, you should qualify for a grant. Visit our Room in Roof Insulation page for further information.

External and Internal Wall Insulation are typically installed in properties that have solid walls or those that are System Built. In other words, they do not have a cavity that can be insulated. It may be possible to have External Wall or Internal Wall Insulation in a cavity wall property if it is not possible or practical to install Cavity Wall Insulation. See our External Wall Insulation and Internal Wall Insulation pages for details.

What if you don't qualify?

If you do not qualify for a Cavity Wall, Loft, Internal Wall or Room in Roof Insulation grant, EnergyLink can still arrange for you to receive a free, no-obligation survey and quote from an approved local Installer. A grant of up to 25% can also be claimed towards the cost of External Wall Insulation.

Unfortunately, we are unable to help with grants for other types of insulation including the following:

  • Pitched/Sloping Roof Insulation

  • Flat Roof Insulation

How can EnergyLink help?

Our Application Form will let you know if you qualify for a grant and also whether it is likely to be 100% funded. After you have filled in the form, we will check to see if the property is likely to be suitable using the EPC register and/or Google Streetview.

Following initial checks, we will allocate you to an accredited Installer who operates in your area. If you provide an email address, we will send you the Installer's contact details. They will telephone you to organise a convenient date and time to carry out a free survey.

The Surveyor will confirm the grant amount and if your property can have insulation, an installation date will be arranged if you would like to proceed.
