Retrofit cost East of England (UK 2026): regional labour-rate premium, stock mix, regional scheme overlays, indicative deep-retrofit envelope.

Off-gas share

The East of England has a meaningful rural off-gas cohort. Oil and LPG households see the strongest case for an ASHP plus BUS; the £9,000 BUS rate from July 2026 for oil and LPG retrofits sharpens that case further.

Indicative envelope

Surveyed 22 June 2026. Ofgem Q3 2026 cap applied (gas 7.33p, elec 26.11p, gas standing 29.04p). Next scheduled review 26 September 2026 (Q4 cap publication). [ref R4]
