Spread the news

When your home has the recommended 270mm of loft insulation you will be warmer in the winter, cooler in the summer and saving £175, as well as 720kg of CO2 a year (every year)[1].

Installing (or topping up your existing) loft insulation is the single most effective measure for improving the energy efficiency of your home.

25%

of heating energy disappears through the roof of an uninsulated house.

Why?

Snug

Snug as a bug in a rug? That’s how your house will feel after wrapping it in a nice thick layer of insulation.

Thermal loft insulation reduces heat loss (and heat gain) by providing a barrier between the inside and outside of your home. It helps to reduce the amount of heat that escapes from it in the winter and protects it from getting too warm in the summer.

Smug

You will be saving in the region of a whopping 720kg of CO2 a year every year when you insulate your loft.

If everyone in the UK installed the recommended 270mm loft insulation, we could save nearly £500 million – and 2.7 million tonnes of carbon dioxide every year, the equivalent of taking nearly 100,000 cars off the road[2].

 

And a little bit richer

Your loft insulation could pay for itself within a couple years and will continue to save you energy for more than forty years.

The Energy Saving Trust estimates that insulating your loft will cost between £50 and £350 and save you about £175 a year on your energy bills. 

How?

There are two routes to getting your loft well insulated: You can do it yourself or you can get a specialist installer to do it for you.

DIY:

Installing your own loft insulation can be done in a day, no matter how experienced or otherwise you are at DIY.

It is important to go for an approved material, one that has been properly tested to ensure it is safe to use in your loft. Look out for Energy Savings Trust recommended products.

Thinkinsulation.com has some useful tips and a video on DIY loft insulation. 

Bring in the professionals:

There are a lot of professional energy efficiency advisers and installers for you to choose from, go to the National Insulation Association website to find a registered installer in your area 

Funding:

And before you make any decisions, why not have a quick word with your energy supplier or local authority to find out what deals are available locally. The energy companies have carbon emission targets they have to meet and as a result they may be subsidising or even giving away loft insulation.

Support:

Make My Home Green gives detailed and impartial advice on ways to make money-saving green improvements to your home – including loft insulation. And better still they have been nice enough to give DoNation users a 15% discount on their Advanced Home Energy Report service so mention discount code 'Do Make My Home Green' when you give them a call.
