The average spend on home improvements carried out over the last 12 months is £5344. The average value perceived to be added to a property as a result of these home improvements is £6466, with an average return on investment of 120%.
Home improvements that respondents perceived not to recoup the actual outlay cost were laminate flooring, new carpets, improvements to the central heating system, new windows and double glazing and new fitted bedrooms.
