What to know about replacing an oil or LPG boiler with a heat pump in Coleraine
Homes around Coleraine range from older terraces to newer estates, and each needs a different design. That is why we survey before we quote.
Bungalows and detached houses near Coleraine running on LPG can move to a heat pump, with the tank collected by the supplier. Rural properties near Coleraine usually have garden space for the outdoor unit, sited away from windows and sheltered where possible.
Off-gas homes have a lot to plan when switching to a heat pump: the fuel tank, older walls, rural power supplies and higher heat loss.
- Detached houses and bungalows with garden space for the unit
- Rural and village homes off the mains gas grid
- Older oil boilers nearing the end of their life
What's included
- Oil tank draining and removal or making safe, as set out in your quote
- Network operator notification and electrical connection
- Free survey with a detailed heat loss calculation for older construction
- Help arranging LPG tank collection with your supplier
- Outdoor unit, heat pump cylinder, controls and radiator changes
For homes outside Coleraine reached by a long drive or narrow lane, delivery of the unit and cylinder is planned in advance.
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 Coleraine.
Installing heat pumps has been zero-rated for VAT in Northern Ireland since 1 May 2023, in line with the rest of the UK, until 31 March 2027. Northern Ireland has its own permitted development rules and building regulations, and we confirm what applies to your Coleraine property at survey.

Designing for Coleraine's winters
Coleraine sees roughly 7 hours 08 minutes of daylight in December and 17 hours 24 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.
What happens after you enquire in Coleraine?
- Tell us about your home: postcode, property type and current heating.
- We book a survey in Coleraine; the surveyor measures rooms, windows and radiators and looks at cylinder space.
- The design and quote arrive in writing, including radiator changes and the outdoor unit position.
- On installation days the old system is removed and the new one fitted and filled.
- We commission the heat pump, show you the controls and register the installation.
Replacing an oil or LPG boiler with a heat pump in Coleraine: questions
Do you cover Portstewart as well as Coleraine?
Yes. We arrange surveys and installation in Portstewart, which is about 4 miles north-west of Coleraine, and across County Londonderry.
Do I need new radiators for a heat pump in Coleraine?
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 Coleraine home gives a room-by-room list.
How long does installation take in Coleraine?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Coleraine home states the expected time.
How much is the grant for replacing an oil boiler with a heat pump?
In England and Wales, the Boiler Upgrade Scheme grant is £9,000 when an air-to-water heat pump replaces oil or LPG heating, for installations from 21 July 2026 to 31 March 2027. Otherwise the standard £7,500 applies. The installer claims it and deducts it from your quote. Scotland's Home Energy Scotland funding works differently and includes extra for eligible rural homes; Northern Ireland has no dedicated homeowner scheme at present.
Will I need bigger radiators in an older cottage or farmhouse?
Often in some rooms, because thick solid walls and older windows lose more heat, and heat pumps work at lower water temperatures than oil boilers. The survey checks each room. Rooms with high ceilings or large windows are common candidates for a larger radiator. Where swapping radiators is impractical, a high-temperature unit can be considered, with lower efficiency as the trade-off.
