Grants and rules for heat pumps in Northern Ireland
Northern Ireland does not have a dedicated heat pump grant for homeowners at present, and the Boiler Upgrade Scheme does not apply here. Heat pumps have sometimes been funded through the Northern Ireland Sustainable Energy Programme, so it is worth checking what is open when you enquire about a home in Newcastle.
There is no VAT on installing a heat pump in Northern Ireland until 31 March 2027, the same as in Great Britain. Planning and building control here follow Northern Ireland's own rules, so the survey checks the unit position against them.
Heat pump guide prices in Newcastle
The ranges below are typical installed prices for homes in County Down, including VAT. A survey sets the exact figure, because two similar-looking houses in Newcastle can need quite different radiators and pipework.

| 2–3 bedroom terrace or semi | 5–7 kW | £10,200–£13,100 |

Short winter days in Newcastle and what they mean
On the shortest day Newcastle gets only about 7 hours 20 minutes of daylight and the noon sun sits around 12° above the horizon. Northern winters tend to be longer, so a well-designed, efficient system matters more here because it runs for more of the year.
Heat pumps in Newcastle: questions
How long does a heat pump survey take in Newcastle?
A home survey in Newcastle usually takes one to two hours. The surveyor measures every heated room, checks windows, walls and radiators, and looks at where the outdoor unit and cylinder can go.
How long does installation take in Newcastle?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Newcastle home states the expected time.
Can you service a heat pump in Newcastle that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Newcastle, whoever fitted them. Tell us the make and model when you book.
What size heat pump does a Newcastle home need?
It depends on the heat loss, not the postcode. As a rough guide, a 3 bedroom semi often needs 6–9 kW, but the room-by-room survey sets the actual size for your Newcastle home.
