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

Does cavity wall insulation make a mess?
It shouldn't - all work is carried out externally through small holes in the brickwork joints. A small amount of dust is created when the holes are drilled. The cavity wall insulation is then blown into place using a hose, straight into the wall, so there are no spills.
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.
Why wasn't my house built with cavity wall insulation and the right amount of loft insulation?
Houses comply with the building regulations that apply at the time the property is built. Since the oil crisis in the early 1970s, the insulation standards in the Building Regulations have been progressively upgraded.
There is a lot of pipework in my loft space. Should I insulate the pipe work too?
Yes, it is a good idea and many insulation installers will do this for you - it usually involves fitting foam 'jackets' over the pipes.
What is loft insulation made of?
Typically, loft insulation is a mineral wool made out of glass or rock fibers. You can also get natural loft insulation made of sheep's wool, hemp or cellulose which will remove the need for protective equipment,
