We cover Larne and nearby Carrickfergus, Ballyclare and the rest of County Antrim. A heat pump is a whole-system change, so the survey looks at radiators, pipework, the hot water cylinder and the best spot for the outdoor unit.

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 Larne.
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.

Designing for Larne's winters
Larne sees roughly 7 hours 12 minutes of daylight in December and 17 hours 20 minutes in June. With a longer heating season than the south, the gains from low flow temperatures and good controls add up over the year.
Heat pumps in Larne: questions
Do I need new radiators for a heat pump in Larne?
Often some, not all. Heat pumps run best at lower water temperatures, so rooms with small radiators may need larger ones. The survey of your Larne home gives a room-by-room list.
Where would the outdoor unit go on a Larne house?
Usually at the side or rear, on a level base with space around it for airflow and servicing, away from bedroom windows where possible. The surveyor checks positions at your Larne home.
How long does installation take in Larne?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Larne home states the expected time.
How soon can you survey a home in Larne?
Survey dates depend on how busy installers are in County Antrim. We offer the next available dates when you enquire and confirm them in writing.
