Paying for insulation

How you pay for insulation jobs will depend on your individual circumstances and the cost of the job. 

You can do simple insulating jobs, such as draught proofing and loft insulation, yourself relatively cheaply. Others need a professional installer and can cost from about £450 for cavity wall insulation to about £10,000 for solid wall insulation.

Blanket insulation comes in roles and is fairly easy to install in your loft yourself

Insulation grants

Cavity wall insulation and loft insulation used to be free for most people, under a government-backed scheme called Cert. This scheme stopped at the end of 2012, but it might still be possible to get a grant towards insulation under the new ECO scheme. See below.

To see if you are eligible,  You can also get a loan to make your house more energy efficient: check our guide to the Green Deal.

Energy grants

Some other grants aimed at helping people to make their homes more energy efficient might help householders pay toward insulation. Check our guide to energy grants for more information.

Green Deal and ECO

Finally, the Green Deal might be a way to pay for insulation. The Green Deal is like a loan (it's not a grant), which is paid back through the savings made on your energy bills due to energy-efficient home improvements you've installed with the borrowed cash. You do not have to pay any money upfront, but you do pay interest rates on the loan. Find out more in our guide to the Green Deal.

There is some free cash available for energy-efficient measures under a grant scheme called ECO, if you meet certain criteria. Check our advice guide on ECO and call the Energy Saving Advice Service on 0300 123 1234 to find out if you could be eligible.

Credit card and mortgages

You can also pay for insulation using a 0%-on-purchases credit card and repaying it over the term of your credit-card deal. Or you could also consider increasing your mortgage to pay for larger and more expensive home improvements, such as solid wall insulation
