- Compared with October 2011, 370,000 more properties had loft insulation, 160,000 more had cavity wall insulation and 6,000 more had solid wall insulation.
- 14.1 million homes had loft insulation of at least 125mm (60 per cent of homes with lofts).
- 11.2 million homes had cavity wall insulation (59 per cent of homes with cavity walls)
- 122,000 homes had solid wall insulation (2 per cent of homes with solid walls).
