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.
- Can I install cavity wall insulation myself?
- No, this is because specialist equipment is needed to install the insulation into the cavity and it's important that the cavity is fully filled with the correct density of insulation. This is why only trained and approved installers are used, and this allows a guarantee can be given on the work. You will also need the work to be professionally done if it is being funded by any government grants.
- I live in a flat, can I get cavity wall insulation installed?
- It's not practical to insulate a single flat in a block. If the property has cavity walls, the whole building should be insulated.
- 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.
- My loft has been fitted with floorboards - will this cause a problem?
- Not necessarily. You can lay the insulation once the floorboards have been taken up, and put the floorboards back over the insulation, or, if you prefer, you can have your insulation lain directly over the floorboards.
- Do I need to provide extra ventilation to my loft space if I insulate it?
- That depends on whether it is adequately ventilated at the moment. Increasing the amount of insulation in the loft can lead to condensation of water vapour on any timber there. If your loft is not properly ventilated your installer will advise you, and can install simple vents that will ensure an adequate air flow through the loft.
