Free Loft Insulation and Free Boilers from Energy Suppliers

Can you get free insulation? Insulating your home is one of the most effective ways to cut your energy bills. Find out how your energy supplier could help.

Some energy suppliers offer free insulation and free boilers to eligible households. Read on to find out if you qualify.

You could save up to £130 a year on your energy bills by insulating your loft, and £145 with cavity wall insulation if you live in a semi-detached house. Both can costs hundreds of pounds upfront to install, so it's worth checking whether you can get free insulation from your energy supplier first.

Read about the different types of insulation available to make your home more cosy.

What free insulation can I get?

Some suppliers offer free insulation if you're eligible under the ECO scheme. For example, you may be eligible if you're 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 energy comparison price website, Which? Switch. If you're on a standard tariff with one of the Big Six energy suppliers – as most people are – you could save around £200 per year by switching to a better deal. Find out if you're on the cheapest energy deal.

EDF Energy – free insulation or subsidised boiler for customers

British Gas and Scottish Power

Neither British Gas nor Scottish Power currently offers free insulation or boilers.

Some companies’ schemes are currently on hold while the government finalises the legislation behind them. They are backed by the Energy Companies Obligation (ECO). The second phase of this has finished but the third has not yet been agreed by government.

Discounts on DIY insulation products

If you decide to install your own loft insulation, look out for the Energy Saving Trust Approved logo to ensure you're buying insulation products that have been through a quality-control process and comply with building regulations. 

You can buy loft insulation from shops such as B&Q and Homebase, and it typically costs between £14 and £25 for a roll.

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 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 – your living room while you watch TV in the evening, for example - you could consider an electric heater. Make sure you get one that doesn't rack up your energy bills using our guide on how to buy the best electric heater.
