How to get Free Cavity Wall Insulation Grants?

If you live in the UK, you can get a free Cavity Wall Insulation Grant as part of our comprehensive home energy efficiency scheme. It’s for everyone using benefits such as Universal Credit, Pension Credit, ESA, etc. Getting wall insulation funding is especially beneficial if you own a house (because it is pretty expensive to fund it on your own).

Energy is getting more expensive. So saving on heat is good for you and everyone else.
As part of a suite of energy-saving measures, insulation can cut your energy bill by up to 30%.

But be quick. Because as winter comes, it’s harder to get this free offer.

** The Cavity Wall Insulation Grant is part of the ECO4 Scheme – you can also check other government energy grants on our website.

How to get Free Cavity Wall Insulation Grants?

What is Cavity Wall Insulation?

A cavity wall is two layers of brick with a cavity between them. Cavity wall insulation or CWI is a process of inserting insulation into a small space between them. Depending on the type of cavity, different materials can be used for the insulation, such as foam, bead, or mineral wool.

But you don’t have to worry about figuring out which one will suit your home. We will send a surveyor to determine whether your property is suitable for government cavity wall insulation (including finding out if cavity wall insulation removal will be needed to replace old insulation in some circumstances) and which one will be most appropriate.

Most homes built with a cavity wall between 1924 and 1982 are likely not filled with any cavity wall insulations. If that is your home, you may be eligible to get cavity insulation entirely for free at no cost to you!

How does Cavity Wall Insulation reduce heat loss?
Cavity wall insulation works by reducing the amount of heat loss from walls. To increase thermal efficiency of the wall, insulation material is blown between the bricks to decrease heat transfer outside the wall.

The air circulation is reduced within cavity walls which are filled with fibreglass insulation. As a result the temperature is significantly better compared to uninsulated walls. Effective insulation will make your home drought resistant and use less energy for heating. It will also reduce your carbon footprint.

Is my House suitable for Free Cavity Wall Insulation?

There is a chance that cavity wall insulations won’t be suitable for your home, but here’s how you can tell if your home is suitable:

  • The external walls are unfilled cavity walls.
  • It has at least a 5cm wide cavity.
  • It was built before 1982 and in some cases 2005.
  • Your home is capable of heating efficiency in the long run.
  • Your property’s brickwork, outer wall or masonry is in good condition.
  • There is little risk of your house flooding.
  • The walls are not exposed to too much driving rain or extreme weather.
  • It is still possible to have it installed even if adjoining properties don’t.
Building regulations changed after 1982 where insulation was required to be fitted on any houses built from that point, but some of them weren’t. The properties built after 1982 that didn’t have cavity insulation fitted could be insulated for free with government funding if they were built before 2005.

Some homes can also need cavity wall insulation removal. In some cases, it may be necessary to extract the cavity wall insulation because the insulated cavity walls were done incorrectly and cause moisture.
You could be suffering from internal damp problems or vermin infestations. Perhaps the insulation was installed incorrectly or is deteriorating. If the insulation was not suitable for your home, then the installation should have been avoided altogether.

If you are still unsure, we could help you! Simply answer some questions, and we will give you a call for some advice and a brief assessment.

Can I Get Cavity Wall Insulation for Free even if I’m Not on Benefits?

Individuals can get wall cavity insulation grants because of the GBIS and ECO4 scheme, as previously mentioned. Unfortunately, housing association tenants do not qualify unless they own 50% of their rented home, though it could be beneficial to contact Pure Environs anyway to see what we can do! Suppose you are not on benefits and believe you are not entitled to receive cavity wall insulation grants (which you can check below). In that case, you may be eligible to get it through your local council or perhaps there are other heating measures Pure Environs can install for you. Get in touch, we may be able to help.

Who qualifies for ECO4 home improvements grant?

Homeowners and private tenants with low incomes  are likely to be eligible for the ECO4 grant and have their heating measures upgraded.

FAQ’s

Why should I do Room in Roof Insulation?

A quarter of heat is lost through the roof in an uninsulated home. Insulating your loft, attic or flat roof is an effective way to reduce heat loss and reduce your heating bills.

Room in Roof Insulation involves insulating the space between the rafters and the room’s interior, transforming your attic or loft space into a comfortable, energy-efficient living area. This process helps maintain a consistent temperature, reducing the need for excessive heating or cooling.

Insulating your room on the roof can significantly enhance your home’s thermal efficiency, leading to reduced energy bills, increased property value, and a more comfortable living environment. It also contributes to reducing your carbon footprint.

Most homes with attic or loft spaces can be suitable for RIR, especially those with traditional rafters and accessible loft areas. Our experts can conduct a free assessment to determine your property’s eligibility.

Yes, installing Room in Roof Insulation can significantly improve your home’s energy efficiency rating by reducing heat loss, which is reflected in your home’s Energy Performance Certificate (EPC).

Homeowners may be eligible for government grants or schemes like the ECO4 to cover or contribute towards the cost of insulation. Visit our Grants page or contact us to find out if you qualify.

We use high-quality, durable insulation materials such as PIR board or mineral wool, chosen for their thermal efficiency, longevity, and compliance with building regulations.
