Wall & Loft Insulation

Home insulation is material that can be added to different areas of your house to help your house retain heat. Fitting insulation means that less of the heat your heating system produces leaves your house, meaning that less fuel is needed to heat your house to the same temperature. This saves you money on your energy bills – as much as several hundreds of pounds a year!

The most effective forms of insulation are:

  • Loft Insulation – This is generally easy and cheap to do and will result in an immediate saving; it’s like putting a woolly hat on your house! Typical saving: up to £175 a year.
  • Cavity Wall Insulation – This is a form of insulation which is injected into the air gap in some types of wall. This is a very cheap but effective way of insulating your house. Typical saving: up to £135 a year.
  • Solid Wall Insulation– If your walls do not have a cavity it is possible to add insulation either on the inside or outside of your house’s walls. This costs a little more but is very effective. Typically saving: around £445 – £475.

There is also funding available for wall and loft insulation under the ECO scheme. Under the HHCRO (Home Heating Cost Reduction Obligation) part of the scheme you could get loft insulation and cavity wall insulation installed totally free of charge – see if you qualify for free insulation and apply on our HHCRO Free Insulation page.

FAQs

How long does it take to install cavity wall insulation?
Most homes can be insulated in about 3 hours, but larger houses may take a whole day.
How do I know if I've got cavity walls or solid walls?
Most cavity walls are identified by two factors. They are about 10½ to 12 inches (270mm - 300mm) thick overall (You can measure this at a door opening) and all the bricks visible on the outside of the wall are all 9 inches (225mm) long (except at corners and openings) (i.e. are mounted lengthways, with 'headers' or the ends of the brick only visible at corners and openings). Solid walls have repeat patterns of 4 inch (100mm) wide bricks as well as 9 inches (225mm) long bricks over the main area of the wall. The walls are usually a little over 9 inches (225mm) thick, although in larger properties the walls can be 13½ inches (330mm) thick.
Are there any grants available for installing solid wall insulation?
The will be a grant scheme available for solid wall insulation under the ECO (Energy Company Obligation), the complementary grant scheme to the Green Deal. Under the ECO (Carbon Saving Obligation), any UK resident will be able to get their solid wall insulation installation either partially or fully funded. It's not yet clear how people should apply for this scheme, as the both the Green Deal and ECO have just launched. It's likely we'll know more in March (2013).
I have lots of rubbish in my loft. Do I need to clear it out or will the installer do this for me?
Yes, you will need to clear the roof of any rubbish or stored objects before the insulation is installed.
Is it true that everyone in the UK is entitled to subsidised insulation?
Yes, everyone is entitled to a subsidy and some people can even have free installation. Why? Because the UK Government is obligated to reduce greenhouse gas emissions by international environmental agreements. One of the easiest ways to achieve a large reduction in greenhouse gas emissions is through increased home energy efficiency. The Government has stated that cavity wall insulation and loft insulation are the most effective methods which is why they have legislated for power/energy utilities and power companies to provide subsidies.
