Home grants Free loft insulation from energy suppliers

House with money

Insulating your home's loft or walls will save money on your energy bills

Insulating your home is one of the most effective ways to cut your energy bills - you could save up to £140 a year by insulating your loft, and £160 with cavity wall insulation.

Here, we reveal how you can get free insulation from your energy supplier. Read on and find out whether you qualify.

What free insulation can I get?

Some suppliers offer free insulation if you are eligible under the ECO scheme. For example, you may be eligible if you are on government benefits, but suppliers will also take into account how much your home will benefit from insulation.

If you're concerned about your energy bills, it's worth seeing how much you could save using our free switching service, Which? Switch. If you're on a standard tariff with one of the Big Six energy suppliers - and most people are - you could save up to £240 a year by switching. Find out if you're on the cheapest energy deal.

What type of insulation do I need?

To work out which type of insulation is right for your home, read our guides to loft insulation and cavity wall insulation.

Before taking up any deal, you'll need to read the small print for each insulation offer to make sure you and your home are eligible. Companies typically need to be able to insulate at least two thirds of your loft space, and exclude properties with more than 60mm of loft insulation already in place. 

You may not be eligible if you live in a rented property, flat or maisonette, or a housing association or council property. Most deals apply only to people living in mainland Great Britain. You may need to pay towards the cost of your 'free' insulation if you live in a particularly large or unusual house.

Heating alternatives

You could also take a look at our guides to wood burning stoves, underfloor heating and solar panels to find out more about these alternative, and potentially cheaper, forms of heating. 

If you only need to heat a specific area - so your living room while you watch TV in the evening, for example - you could consider an electric heater. Find out more about how to get one that doesn't rack up your energy bills - see how to buy the best electric heater.
