Keeping your home warm and your energy costs down

Home insulation will help you to stay cosy, save money and protect the planet. So what’s holding you back?

Did you know...?

  • Heat flows from a warm area to a cold area. Wall and loft insulation makes it difficult for heat to pass outside by providing a layer of material with air pockets that trap the heat.
  • Around half the heat lost in a non-insulated house is through the walls and loft.
  • Up to a quarter of the heat lost in a non-insulated home is through the roof.
  • Around a third of the heat lost in a non-insulated house is through the external walls.
  • Increasing your home insulation not only lowers your energy bills but helps reduce carbon emissions.
  • Home insulation is cost-effective and will pay for itself over and over.

Cavity wall insulation

Cavity wall insulation fills the space between your exterior walls with insulating material. It helps save energy and money, as well as making your home feel much warmer. Cavity wall installation can also reduce condensation in your house. Installation of cavity wall insulation is guaranteed for 25 years by the Cavity Insulation Guarantee Agency (CIGA)

Loft insulation

Insulating your loft can save you a fortune on annual energy bills, by adding insulation between the ceiling and the roof. The recommended depth of loft insulation for a home is 270mm, so if your loft is already insulated it pays to check that it’s adequately insulated

Draught proof your floors

Draught proofing floors and fixing gaps is an easy, affordable way to retain warmth in your home and cut down energy bills. And it’s a job that you can do yourself quite simply. DIY draught proofing costs under £100 yet can save you around £50 a year.

You can insulate beneath timber floors by lifting the floorboards and laying insulating material, supported by netting, between the joists. Use a tube sealant, such as silicon, to fill any gaps between the floorboards and skirting boards. Make sure you don’t block ventilation to your floorboards by sealing under-floor airbricks in external walls. And be aware that some rooms, such as bathrooms and kitchens need to properly ventilated.

Cheap and easy heat-saving devices

  • Use draught excluders at the bottom of doors and across your letter box to keep warmth in and cold air out.
  • Attach a sheet of tin foil behind radiators to reflect radiant heat back into the room. You can buy special radiator foil for this but household tin foil attached to cardboard is cheaper and just as effective.
  • A shelf above radiators helps to deflect heat to the middle of the room.
  • Block gaps on windows and around electrical fittings.

Top Tip

 

Get a grant. The government, local authorities and energy suppliers all offer some sort of funding if you have your home insulation installed by approved fitters. Some local authorities will also provide grants for do-it-yourself loft insulation. If you are on a low income, you may be eligible for free cavity wall insulation and loft insulation. Landlords with home insulation can also get an energy saving tax allowance on each property they own.
