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.
- Are there grants available for cavity wall insulation and are there strict criteria as to who is eligible, like with loft insulation?
- There are grants available for cavity wall insulation available through the CERT (Carbon Emissions Reduction Target) scheme, which is available through the energy suppliers. You can apply to any of the larger suppliers regardless of whether you're a customer of theirs. The scheme is now only available through British Gas and Scottish Power, as most of the scheme shave run out - apply now if you could benefit. The ECO (Affordable Warmth) scheme is due to replace CERT, and is currently operating, but has stricter criteria on who's eligible, focusing on less well off customers.
- 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.
- 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.
- 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.
