Free government cavity wall insulation grants

Cavity wall insulation

Remarkably, about one third of all the heat lost from homes disappears straight through the walls. Don't worry though, cavity wall insulation grants are available to help you keep a lot more of the heat in where it belongs and make your house cosy. Providing you're in receipt of certain benefits, you could be eligible for free cavity wall insulation.

Who is eligible for an insulation grant?

Under the government's Energy Company Obligation (ECO), recipients of certain benefits could benefit from a free grant towards loft insulation. If you receive any of the below benefits you could be eligible for the scheme:

  • Child Tax Credit
  • Working Tax Credit
  • Income Support
  • Income-based Job Seeker's Allowance
  • Income-Related Employment Support Allowance
  • Universal credit
  • Pension Guarantee Credit.

It is important to note that there are other criteria to meet (such as your current home status and income level) but the best place to start is to fill in our simple online form and let us assess your eligibility.

You'll need to check if your property has the correct type of walls for this insulation. If you're not sure if your home has cavity walls, there's an easy way to tell. Take a look at the external brickwork on your home. If all the bricks run in the same direction, without any half bricks, then it is very likely a cavity wall. This is called stretcher bond brickwork.

Who funds the scheme for these insulation grants?

The scheme is funded by the Big Six energy companies. Improving home insulation for low income households helps to reduce the amount of energy wasted through heating that escapes through roofs and walls. The government is trying to reduce our energy usage in line with targets set by the EU.

Are there any costs involved?

The cavity wall insulation isn't guaranteed to be free, although in some cases you can get a 100% grant (making it completely cost free). You may have to make a contribution towards the cost of the work. It's also important to note that the grant itself is completely free and you would never pay any of it back.

Do you really need cavity wall insulation?

If your home was built between 1924 and 1982, then the answer is probably going to be a yes.

A cavity wall is made of two layers of masonry bricks with a gap of at least 50mm in between. The cavity wall design with masonry bricks was chosen for its damp-proofing properties, but doesn't provide great insulation. It wasn't until the early 1980s that Building Regulations specified that properties with a cavity should be filled. So if your home was built between those dates, you really should take advantage of the cavity wall insulation grants that may well be due to you.

Cavity wall insulation can prevent up to 35% of heat escaping through your walls. In monetary terms, you could be looking at savings of up to £145 a year for a typical family home. You can also cut your carbon emissions by up to 610kg a year. If you're eligible, the whole cost of cavity wall insulation could be paid by a government grant. You'll also get a 25-year CIGA guarantee from the Certified Insulation Guarantee Agency.

The installation process

Cavity wall insulation is a very quick and straightforward process. It'll just take two or three hours to insulate a typical family home. The insulation process needs to be carried out by an expert. If you're eligible for one of the cavity wall insulation grants, you'll get an approved professional to do the job.

They bore a series of small holes into the mortar around the brickwork and inject the insulating material through the halls where it expands to fill the cavity. When it's all done, they'll patch up the holes for a nice neat finish.
