Analysis for WWF and UK-GBC: achieving minimum EPC standards in housing

This research, conducted by Parity Projects, examined 3,000 properties rated as EPC band “F” or “G” and modelled the improvements that would be needed to reach EPC band “E”.

It found that:

  • The average cost of reaching band “E” was only £1,421 per home
  • The average annual energy bill saving by reaching band “E” was £409 per annum
  • More than 70 per cent of the properties were able to reach band “E” for less than £1,000.

All of the properties examined were also able to comply without resorting to measures which may require planning permission, such as external wall insulation or solar PV.
