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.
- I've got a timber framed house - can I still get cavity wall insulation installed?
- It's not possible to install cavity wall insulation into timber framed houses.
- 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.
- I live in a rented property, can I still get my walls and loft insulated?
- Yes, people living in rented property can get their homes insulated, whether you fund it yourself, your landlord funds it or you get it funded through the Green Deal, but you must get the permission of the owner or landlord. There could also be a tax benefit to your landlord if he covers the cost - look at our LESA (Landlord’s Energy Saving Allowance) page to find out more detail.
- I already have some loft insulation - do I need to install more?
- If your loft insulation is 100mm or less you would certainly benefit by having it topped up with more insulation to make it up to a 270mm thickness. The Energy Saving Trust estimates that top-up loft insulation can save the average householder as much as £60 per year at current energy prices.
