Savings following cavity wall insulation depend on a number of different factors, such as:
See below for typical savings:
|Measure||Annual saving per year||Cost||Payback||CO₂ saving per year|
|Cavity wall insulation||Up to £160 (England, Scotland and Wales) Up to £230 (Northern Ireland)||£450 - £500||4 years or fewer||Around 650kg (England, Scotland & Wales), 790kg (Northern Ireland)|
|Solid wall insulation||Around £260 (England, Scotland & Wales) £380 (Northern Ireland)||£5,000 - £18,000 (external)|

Figures above are based on a gas heated semi-detached house (three bedrooms). All data obtained from the the Energy Saving Trust (EST).
Remember, these savings are made every single year, so making an investment in insulation now will save both energy and money, year in, year out.
The data we use to work out energy and water costs come from a range of reliable international sources to give an average figure. Figures are rounded up or down to the nearest whole number.
* Total amounts potentially saved do not include lighting in individual rooms, or use of secondary heating.
