Air Source Heat Pump Cost in Antrim, NI

Antrim (BT41) is a sizeable town in Northern Ireland with a cooler northern climate with cold snaps and frosty mornings. An air source heat pump here typically costs £8,050 to £14,050 fully installed (in line with the regional average; indicative, June 2026). Northern Ireland has no Boiler Upgrade Scheme equivalent, so that is the full price, though 0% VAT on residential installations until 31 March 2027 is already reflected in quotes. This is one of the UK's cooler heating climates, so specification matters more here. Modern units hold useful output well below freezing, but ask your installer about low-temperature performance and defrost behaviour, and expect the MCS heat-loss survey to drive the sizing decision. Radiator upgrades are more commonly recommended here so the system can run at efficient, lower flow temperatures.

Antrim is a sizeable town in the wider Northern Ireland urban area. Several MCS-certified installers service this part of Northern Ireland, and that competition helps keep air source heat pump quotes in check. Comparing two or three quotes is still the best way to land at the right price.

Mains gas is patchy around Antrim: a sizeable share of homes heat with oil, LPG, or electric storage instead. Those are the systems a heat pump beats hardest on running cost.

Compared to nearby Randalstown, Antrim is slightly more affordable for air source heat pump installation. Getting quotes from installers who cover both areas can help you find the best price.

The heating picture in Northern Ireland

Northern Ireland is a genuinely different market: most homes heat with OIL, not mains gas, and there is currently no Boiler Upgrade Scheme equivalent - the £7,500 grant does not apply here. The 0% VAT relief still does. Heat pump economics rest on oil-price exposure and running-cost savings rather than grants; limited efficiency support exists via NI schemes (see nidirect.gov.uk).

Northern Ireland is a different market from Great Britain: most homes heat with oil, and there is currently no Boiler Upgrade Scheme equivalent, so the installed price is the full price. What still applies is 0% VAT on residential heat pump installations until 31 March 2027, and the running-cost case against oil. Limited efficiency support exists through NI schemes (see nidirect.gov.uk).

Grants and Support in Antrim

The straight answer: Northern Ireland currently has no Boiler Upgrade Scheme equivalent, so the installed price above is the full price. 0% VAT on residential installations (until 31 March 2027) is already reflected in quotes, and limited efficiency support exists through NI schemes on nidirect.gov.uk. Accurate as at June 2026.

Heat pump grants

No Boiler Upgrade Scheme equivalent in Northern Ireland

The £7,500 grant available in England and Wales does not apply here. If a website or salesperson promises it for a Antrim postcode, they are describing the scheme in England and Wales. Limited efficiency support is listed on nidirect.gov.uk.

UK-wide tax relief (automatic)

0% VAT on heat pump, solar and battery installations

Residential installations of heat pumps, solar panels and home batteries are zero-rated for VAT until 31 March 2027 (then 5%). Applied automatically by the installer - typically worth £1,000-3,000 on a heat pump job versus standard 20% VAT.

Frequently Asked Questions

How much does an air source heat pump cost in Antrim?
An air source heat pump in Antrim typically costs £8,050 to £14,050 fully installed (indicative, June 2026). Northern Ireland has no Boiler Upgrade Scheme equivalent, so that is the full price, although 0% VAT applies to residential heat pump installations until 31 March 2027 and is already reflected in quotes. The final price depends on the heat-loss survey, whether a hot water cylinder needs adding, and any radiator upgrades.
What heat pump grants are available in Antrim?
Northern Ireland currently has no Boiler Upgrade Scheme equivalent: the £7,500 grant available in England and Wales does not apply here. Two things still help: 0% VAT on residential heat pump installations until 31 March 2027 (typically worth £1,000 to £3,000 versus standard VAT), and limited efficiency support through NI schemes listed on nidirect.gov.uk. Budget the full installed price of £8,050 to £14,050 (indicative, June 2026).
Do air source heat pumps work in Antrim's climate?
Antrim has a cooler northern climate with cold snaps and frosty mornings. This is one of the UK's cooler heating climates, so specification matters more here. Modern units hold useful output well below freezing, but ask your installer about low-temperature performance and defrost behaviour, and expect the MCS heat-loss survey to drive the sizing decision. Radiator upgrades are more commonly recommended here so the system can run at efficient, lower flow temperatures.
Is a heat pump cheaper to run than a gas boiler in Antrim?
On the Ofgem price cap (electricity around 25p per kWh, gas 5.74p rising to 7.33p per kWh on 1 July 2026), a heat pump running at a seasonal efficiency (SCOP) of 3.8 to 4.5 delivers heat at roughly the same cost as a 90%-efficient gas boiler or below it, and the 27% gas rate rise tilts the comparison further toward the heat pump. Households on heat-pump time-of-use tariffs typically do better again, though tariffs change so compare current offers. These are estimates: your actual costs depend on your tariff, your home's heat loss and how the system is set up.
How does the installation process work in Antrim?
Every professional installation starts with a heat-loss survey of your home, which determines the heat pump output, the radiator sizing and whether your hot water cylinder needs upgrading or adding. The installer then fits the outdoor unit, cylinder and controls, commissions the system and walks you through it. If a gas boiler is being removed, that part of the work must be done by a Gas Safe registered engineer. Timescales are usually measured in days, not weeks; your installer will confirm after the survey.
What size air source heat pump do I need in Antrim?
Sizing in the UK is driven by your home's heat loss, not just bedroom count: the heat-loss survey calculates it room by room. As a rough guide from the current UK model ranges, smaller well-insulated homes suit units around 5 to 8kW of heat output, typical 3 to 4 bed homes around 8 to 12kW, and large or older properties may need more. In a cooler climate like yours, the survey matters even more: low-temperature output and radiator upsizing are the difference between a system that just works and one that works efficiently.
Which air source heat pump brand is best for Antrim?
In Antrim's cooler climate (zone 5 on our 1-7 scale), cold-weather output matters most. Mitsubishi Electric Ecodan (assembled in Livingston, Scotland) and Daikin Altherma both have strong cold-weather pedigrees, and Vaillant aroTHERM Plus and Viessmann Vitocal use R290 refrigerant to reach high flow temperatures, which suits radiator retrofits. Whichever brand you choose, ask the installer for low-temperature output figures.
