The heating picture in South East England

Most homes here heat with a mains-gas boiler, and the Ofgem price cap gas rate jumps 27% on 1 July 2026 (5.74p to 7.33p/kWh). With £7,500 off through the Boiler Upgrade Scheme and 0% VAT until March 2027, replacing the boiler with an air source heat pump at end-of-life is now cost-competitive up front and on running costs. Off-gas villages across Kent, Sussex and Hampshire heat with oil - those homes qualify for the higher £9,000 grant from 21 July 2026.
