Installing insulation will help you save money on your energy bills. Loft insulation can save you £180 a year, floor insulation could save you £85 a year, and - depending on the size of your home - cavity wall insulation can save you between £75 to £250 a year. 

Over time, insulation will pay for itself with the savings you make on your energy bills - so it's worth doing. If you need help with the initial cost of installing insulation, read on to find out what our experts recommend. 

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 £415 for cavity wall insulation to about £10,000 for solid wall insulation.

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.

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.

Energy Company Obligation

There is some free cash available for energy-efficient measures under a grant scheme called the Energy Company Obligation, ECO, if you meet certain criteria. Check our advice 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
