You spend less warming your house up when you keep the heat in, so a well-insulated home can really lower your bills.
As part of that, we’re offering free insulation to homes across the country. You don’t have to be a British Gas customer and you don’t need to buy anything from us. You can get free insulation for free even if you’re renting. Just ask your landlord first.
|Cavity wall insulation||£275||£160||£105||£110|
|Loft insulation (0-270mm)||£240||£140||£135||£200|
This is what the Energy Saving Trust estimate. You can find out more at energysavingtrust.org.uk
If your loft looks like this, it’s not insulated yet – we could help.
If you can see your beams, your home might benefit from more insulation.
(if your home has solid walls, you may need solid wall insulation instead.)
If your walls looks like this, we might be able to insulate them.
If your walls look like this, they're already well insulated.
If your house was built before the 1920s, it probably has solid walls. These houses tend to let more heat escape than ones with cavity walls.
You can fix that with solid wall insulation: a layer of insulation fixed to the outside of your home. It helps stop heat travelling through the walls – so your home will be warmer in the winter and cooler in summer.
Your home could still benefit from free insulation, if you privately rent your home.
 There are a few areas of the country we can’t reach, to check if you live in one of them just give us a call. We’ll cover the cost of the insulation itself but if your house needs more vents than usual, or we need to use scaffolding, you may need to help with the cost. But don’t worry, we’ll tell you in advance if this applies to your home.
