Air-to-air heat pumps in Lisburn: what to expect
Most homes can run on a heat pump if the system is designed properly, and Lisburn is no different. The key is matching the heat pump and radiators to the home's heat loss.
Extensions and garden rooms in Lisburn that are hard to connect to the main heating can have their own air-to-air unit. A survey in Lisburn covers indoor unit positions, pipe routes and hot water for homes across County Antrim.
An air-to-air heat pump warms rooms directly with air, and can cool them in summer, but it does not heat your hot water.
- Households that already have, or will add, a separate source of hot water
- Homes where fitting radiators and pipework would be very disruptive
- Rooms that get too hot in summer as well as cold in winter
What's included
- Free survey covering rooms to heat, unit positions and hot water options
- Refrigerant pipe runs to each indoor unit, made and charged by an F-gas certified engineer
- Condensate drains and neat external pipe covers
- Electrical supply and controls set up for each room
- Outdoor unit and indoor units for each room
Flats in Lisburn on storage or panel heaters can often switch to air-to-air without fitting radiators or pipework.
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 Lisburn.
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 Lisburn property at survey.

| Air-to-air heat pump, multi-room 3–4 bedroom home | £3,900–£7,750 |
Installed, inc VAT. Air-to-air systems heat (and can cool) rooms but do not provide hot water.

- We commission the heat pump, show you the controls and register the installation.
Air-to-air heat pumps in Lisburn: questions
Can you service a heat pump in Lisburn that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Lisburn, whoever fitted them. Tell us the make and model when you book.
Do you cover Belfast as well as Lisburn?
Yes. We arrange surveys and installation in Belfast, which is about 7 miles north-east of Lisburn, and across County Antrim.
What size heat pump does a Lisburn 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 Lisburn home.
Can air-to-air heat pumps cool as well as heat?
Yes. Most air-to-air systems can reverse their cycle to cool and dehumidify rooms in summer, which makes them useful for loft rooms, south-facing extensions and home offices that overheat. Cooling uses electricity, so running costs rise if it is used heavily. You control heating and cooling for each room separately.
Can an air-to-air heat pump heat my water?
No. An air-to-air heat pump heats and cools the air in rooms but does not produce hot water. You need a separate source, such as an existing immersion cylinder, a hot water heat pump or an electric water heater. If you want one system for heating and hot water, an air-to-water heat pump with a cylinder is the alternative.
