The benefits of Wall & Loft Insulation

It is pretty much universally agreed that around a quarter of the heat in your home is lost through the roof and a further third is lost through the walls – maybe more! The more that this heat loss is reduced the easier – and cheaper – it will be to heat your home.

You can even get your walls and loft insulated FREE if you meet certain criteria.

Some of the main benefits for insulating your walls and loft are:

  • Optimal Temperature - Comfort is improved year-round as it will be easier to control the temperature of your home, both keeping it warm in winter and cool in summer
  • Reduces Energy Bills - by over 40% and it pays for itself in around two to four years, and keeps paying for itself year after year for over 40 years
  • Reduce Carbon Emissions – Saves non-renewable resources as less energy is need to heat your home, reducing greenhouse gas emissions
  • Reduced Condensation – When fitted well it will virtually eliminate condensation on walls and ceilings
  • Sound Proofing - Insulation materials are often very effective at sound proofing
  • Improve your Home Efficiency Rating - The EPC (Energy Performance Certificate) is used whenever a home is sold or rented to measure its energy performance - insulation will improve its rating

Overall the savings for insulating your walls and loft could be £265 per year and 1.4 tonnes of carbon! This could be even more if you have solid walls.

Few investments are this good!

You can even get your loft and cavity wall insulation installed for free through the HHCRO scheme, part of the ECO, the grant scheme running alongside the Green Deal. The scheme is paid for by the energy companies. You can check whether you qualify for free insulation and apply through us by heading to our HHCRO Free Insulation page.

There are also grants available for solid wall insulation through another part of the ECO. It’s not yet clear how customers will be able to apply for this scheme. It’s likely we’ll know more in May 2013 – we’ll update this page when we do.

FAQs

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.
How do I find out how much loft insulation I have?
Simply push a tape measure or ruler down the side of a piece of loft insulation until it hits the plasterboard ceiling and read off the depth.
I want to use my loft for storage, how can I do that if it is insulated to the depth recommended?
You or your installer can instead lay down innovative loft boards called Space Board. These are insulation boards made from Polyfoam extruded polystyrene designed to be placed on top of the ceiling joists instead of the 170mm mineral wool insulation. You should still aim to lay down 100mm of standard insulation between the joists.
Is it true that everyone in the UK is entitled to subsidised insulation?
Yes, everyone is entitled to a subsidy and some people can even have free installation. Why? Because the UK Government is obligated to reduce greenhouse gas emissions by international environmental agreements. One of the easiest ways to achieve a large reduction in greenhouse gas emissions is through increased home energy efficiency. The Government has stated that cavity wall insulation and loft insulation are the most effective methods which is why they have legislated for power/energy utilities and power companies to provide subsidies.
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,
