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.
- What guarantee of workmanship should I look out for in a cavity wall insulation installer?
- Cavity wall insulation installers can sign up to a professional code of practice, such as those provided by the Cavity Insulation Guarantee Agency, which guarantees the work for 25 years. The installer should carry out post-installation checks on both the inside and the outside of the property, and you will be asked to sign a form to show you are happy with the work.
- I'd like to make my period home more energy efficient, but will internal wall insulation ruin my original features, and will I lose floor area?
- Internal wall insulation is a fantastic solution for period properties or listed buildings that would require planning permission for any changes made to the outside, or where the owner wants to maintain the authentic exterior appearance of the property. You don't need to worry about losing your original features or significant amounts of floor space, though. Modern internal wall insulation systems are extremely slim, yet ultra-efficient, and lead to minimal loss of usable floor area. Installing internal wall insulation does mean that fittings such as plug sockets and skirting boards need to be repositioned, so you'll need to make sure that any decorative features like cornicing or picture rails are carefully removed and refitted following the installation. Insulating the walls could reduce the annual carbon dioxide emissions associated with your home by around 2 tonnes and save £400 per year on your energy bills.
- How long does it take professionals to install loft insulation?
- It takes professional installers about 2 hours to install loft insulation in an average sized loft.
- 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.
