Oil and LPG homes in England and Wales with no mains gas get £9,000 off an air source heat pump until March 2027, £1,500 more than the standard grant. These homes are often larger and older, so we rank models of 7 kW and up by flow temperature: the LG Therma V R290 Monobloc 12kW leads at 75°C.

SCOP and sound power from MCS product listings and manufacturer data; maximum flow temperature as the maker publishes it. Installed prices are modelled before the grant; your quote depends on your home. Last checked 2026-10-20.
What to look for
- Oil and LPG prices make the switch pay back faster than from mains gas, before the higher grant.
- Rural homes are often larger with higher heat loss, so the right size from a proper heat-loss survey matters more than the brand.
- Your MCS-certified installer claims the grant for you and deducts it from the quote.
