To ask the Scottish Government whether (a) it or (b) its agencies play any role in examining the effectiveness of cavity wall insulation following its installation.
Answered by: Kevin Stewart 6 June 2017
The Scottish Government offers a range of schemes to support people who have difficulty paying their fuel bills or keeping their home warm.
These schemes help to increase the take-up of home energy efficiency measures and reduce fuel poverty. As far as the effectiveness of individual installations of cavity wall insulation is concerned, Scottish Government and UK energy efficiency programmes each have their own arrangements in place for inspection and quality monitoring, which vary from scheme to scheme.
The Energy Saving Trust manages a number of these schemes for the Scottish Government. It also offers advice on the amount householders can save, on fuel bills and CO2, by making energy efficiency improvements, including installing cavity wall insulation. These saving figures are either calculated using models or are based upon evidence from field trials of products.
If a householder has concerns about the technical quality or effectiveness of cavity wall insulation installed in their home, they should in the first instance contact their installer. If they are unable to resolve the matter, or are unable to identify the installer, or the installer has gone into liquidation, they should contact Home Energy Scotland for advice. Where a guarantee is in place the next step would normally be for the guarantee agency to arrange for an independent inspection.
Householders who are considering energy efficiency improvements are encouraged to contact Home Energy Scotland, who can offer free, impartial advice on how they can save money and make their home warmer.
