United Kingdom summary
Gas boilers dominate in urban areas; oil, LPG, and direct electric remain common off-grid.
The UK has a mild but damp heating season, with local variation between coastal, urban, rural, and northern homes.
Heat pump suitability depends strongly on fabric condition, radiator output, electricity tariffs, and installer design.
Typical heating context
- Mains gas boilers
- Oil boilers in rural homes
- Direct electric heating
- LPG in off-grid homes
Energy cost assumptions (planning ranges)
- Electricity: GBP 0.22-0.34 per kWh (Ofgem regional cap spread and available tariffs)
- Gas: GBP 0.05-0.11 per kWh (Ofgem cap benchmark and regional/tariff variation)
- Heating oil: GBP 0.09-0.13 per kWh equivalent (kerosene supplier tracking, delivery-size and season dependent)
Electricity/gas benchmarks align with Ofgem's 1 April to 30 June 2026 cap context (24.67p/kWh electricity and 5.74p/kWh gas GB average, Direct Debit) and broader tariff variation. Heating-oil range uses UK supplier-tracked kerosene pricing converted to kWh-equivalent planning values.
Grant and support schemes
Boiler Upgrade Scheme: typically GBP 7,500 for eligible ASHP/GSHP installs in England and Wales
The Boiler Upgrade Scheme may support eligible heat pump installations in England and Wales. Devolved rules and support can differ.
Heat pump suitability notes
Best outcomes are usually in homes with improved fabric, lower flow temperatures, and time-of-use electricity optimisation.
Worked example (illustrative)
If electricity is GBP 0.28/kWh and gas is GBP 0.08/kWh, a heat pump with SCOP 3.2 has delivered-heat energy cost near GBP 0.09/kWh versus about GBP 0.09/kWh from a 90% gas boiler before standing charges.
