What affects air source heat pump costs in Northern Ireland
Tradespeople in Northern Ireland typically charge £145 to £195 a day, which is 12% below the UK average and the single biggest reason prices here differ from the national figure.
Northern Ireland has the highest rate of owner-occupation in the UK and a newer housing stock than most of Great Britain, with a large share of post-war and recent detached houses and bungalows outside Belfast. Belfast itself retains substantial Victorian terraced streets. The defining feature for heating work is fuel: around two thirds of homes are heated by oil rather than mains gas, far more than anywhere else in the UK.
Mild, wet and windy, with rainfall above the UK average and few extremes of temperature in either direction. The mild winters shorten the heating season and suit heat pumps well on paper. Wind is the more demanding factor for roofing and solar fixings, particularly along the north and east coasts.
Planning and building regulations in Northern Ireland
Northern Ireland has its own Building Regulations, separate from both England and Scotland, and its own planning system administered by the eleven councils. Guidance written for England does not apply. Several Great Britain funding schemes do not extend here at all, which changes the economics of energy work substantially.
Grants and schemes in Northern Ireland
There is no grant for air source heat pump work in Northern Ireland, so the figure above is what you would pay. Energy schemes are devolved, and this is one of the places where that matters most: the Boiler Upgrade Scheme covers England and Wales, Scotland runs its own grant of the same value, and Northern Ireland has neither.
Eligibility and scheme details change. Always check the official page before you commit to the work.
