Recent changes
Octopus's earlier 'from £500' headline was ruled misleading by the ASA in Aug 2025 (fewer than 6% of installs met it); it now publishes a typical (median) post-survey price as its anchor and rolls the quote window forward each quarter. That figure fell from £4,459 (quotes 1 Sep 2025 to 28 Feb 2026) to £4,064 on the 1 June to 30 September 2026 window, checked 1 Oct 2026; the same page cites a national average install of £5,408 for comparison. BUS grant is £7,500 for ASHP/GSHP, plus a £1,500 off-gas-grid oil/LPG uplift (£9,000 total) from 21 Jul 2026 to Mar 2027. ~40k cumulative installs by end-2025; vertically integrated R&D facility (Slough) shipping the own-brand Cosy 6 unit.
