Wall Insulation

You could save around £475 per year

Check List:

  • Go into your loft and see if you have insulation on the floor
  • Find out when your house was built
  • Stand near doors and windows to detect breezes

So how does insulation save money?

Insulation helps trap heat within your home by not allowing it to escape. 

It’s important to insulate your entire property not just your walls. 

Why do I need to insulate my walls?

British houses were mostly built early in the last century. We have some of the oldest properties in Europe. 

While well built, they did not feature many of the modern technologies used today to ensure heat isn’t lost. 

Many of us live in homes which literally have holes in them leaking heat.

If our car leaked petrol we wouldn’t be driving it on the road.


The main types are:

  • Wall insulation – there are two sorts depending on the property type. Modern houses (after 1950) have cavities between the external walls. These should be filled. It’s a simple and safe job that effectively injects insulation into your walls. It costs around £350 to do and can save you £135 per year. If your house is older it will probably only have one wall layer, called solid wall. This is particularly inefficient. This should be clad with insulation, either internally or externally. It is a big job, but modern insulation techniques mean the cladding is thinner than it used to be. The cost is upward of £10,000 but there should be some financial assistance in the 2013 with the Green Deal. It can save you around £475 per year.
  • Loft insulation – This is found, not surprisingly, in your loft. It’s the fluffy stuff that can be found up there. It should be around 30cm thick. If you have none or not enough you should top it up. It costs up to around £300 to fit but can save you around £175 every year.
  • Draught proofing – This is a simple technique that just fills in the various small gaps in your house that leaks air. This can be simple measures like letter boxes, key holes, unused chimneys and small holes in the floor. It can cost £120 to have these holes filled in, but can save you around £55 per year. 
  • You can also have floor insulation to help block up the gaps in your timber floors. This can save around £60

Where do I get insulation from?

You can do some yourself, like loft insulation. But energy companies are currently obligated by the government to help you with the cost, so you should start by contacting your energy provider.  Some of them will even clear your loft for you.
