This research project aimed to assess the nature and underlying causes of the relationship between solid wall insulation and property price.
Properties were valued before and after solid wall insulation was installed, with the change in average property price being compared against the change in average price of a control group. Qualitative interviews were used to investigate the key drivers of the change in price, and surveyors’ attitude to- and understanding of- solid wall insulation and its potential to reduce energy bills.
Key findings of the project are that solid wall insulation tends to lead to an increase in property price, although the average change in price was not significantly different to that of the control group. The change in price was most strongly related to perceived improvement to the properties’ aesthetic appearance.
