Best Areas for Heat Pumps in the UK

Not every area benefits equally from a heat pump. The best locations share a few characteristics: a high percentage of homes off the gas grid (where oil and LPG costs are steep), milder climates that boost COP efficiency, decent insulation levels, and access to competitive electricity tariffs.

We ranked every postcode district in the UK by overall heat pump value — factoring in installation cost after the £7,500 BUS grant, annual running cost savings, COP performance, and off-gas grid percentage. The result is an honest picture of where heat pumps make the most financial sense.

Where Heat Pumps Make Less Sense

These postcode districts see the smallest savings from heat pumps — often because homes are already on cheap mains gas, have poor insulation driving up electricity use, or sit in colder regions where COP drops. This doesn't mean heat pumps won't work — just that the financial case is weaker without off-peak tariffs or better insulation.

Highest Off-Gas Grid Areas

These areas have the highest percentage of homes without mains gas. Households on oil or LPG boilers stand to save the most from switching to a heat pump — often £300-600 per year in running costs, on top of the £7,500 BUS grant covering most of the installation.
