Energy UK Explains: Great British Insulation Scheme


  • The Great British Insulation Scheme (GBIS) sees energy suppliers deliver grant funding for insulation measures (such as cavity wall insulation) to eligible households. GBIS was announced by the UK Government in 2022 in response to the unprecedented increase in international wholesale gas prices.
  • The scheme is likely to reach a total of 300,000 households over three years.
