Notes

  • Measures installed in homes under each scheme, by the month of installation, as Ofgem notifies them to DESNZ: a home can receive more than one measure. Recent months rise as late notifications arrive. The schemes are separate and are never added up.
  • The Great British Insulation Scheme has ended: DESNZ published its final monthly figures in May 2026 and plans one more release for final revisions. Its figures are official statistics; ECO's are accredited.
