Insulating your home


Around a third of all the heat lost in an un-insulated home is lost through the walls and another 25% through the roof. Floors, walls, lofts, windows and hot water tanks can all be insulated to increase the energy efficiency of a home. Insulation can be one of the most cost-effective ways to cut energy loss and reduce harmful carbon dioxide (C02) emissions.

Each energy efficiency measure you install could save you a significant amount off your fuel bill and more importantly reduce your carbon footprint:

What could I save?
  • Cavity wall insulation can save you up to £115 each year and reduce your C02 emissions by 610kg.

  • Solid wall insulation can save you up to £400 each year and reduce your C02 emissions by 2,000kg for internal insulation and 2,100kg for external insulation.

  • Full loft insulation (270mm) can save you up to £150 each year and reduce your C02 emissions by 800kg.

  • Draught proofing can save you up to £25 each year and reduce your C02 emissions by 130kg.

  • Floor insulation can save you up to £50 each year and reduce your C02 emissions by 270kg.

There are grants and discounts available in your area to help install energy efficient measures.  If you’re over a certain age (typically 60 or 70) or receive certain benefits you may qualify for free or discounted insulation. 

Call 0800 512 012 or email advice@est-nyh.org.uk to ask any questions and to apply for any grants you may qualify for.

To search for grants and discounts in your area please view our grant information.

All measures, costs and savings are correct at time of publishing. However, financial savings will change as energy prices rise or fall. Please refer to energysavingtrust.org.uk for the most recent measure costs and savings.
