Air source heat pump installation for Lisburn homes
Every property in Lisburn is different, so the design starts from measurements rather than a rule of thumb. That keeps the system the right size and the running costs predictable.
For older properties in Lisburn, the heat loss calculation looks closely at solid walls, single glazing and draughts before any unit is sized. Terraced streets in Lisburn often mean a compact unit position at the rear, so siting and sound levels are checked carefully.
We survey your home, design a heat pump system around its real heat loss, and manage the installation from the first visit to the MCS certificate.
- Homes replacing a gas, oil, LPG or electric heating system
- Houses with reasonable insulation, or a plan to improve it
- Households with room for a hot water cylinder
What's included
- Outdoor unit, hot water cylinder and weather compensation controls
- MCS registration and certificate, plus network operator notification
- Radiator and pipework changes where the design needs them
- Free home survey and room-by-room heat loss calculation
- Commissioning, handover and a walk-through of the controls
In Lisburn, cylinder space is planned with you, often in an airing cupboard, utility room or garage.
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.
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.
What to budget for air source heat pump installation in Lisburn
The ranges below are typical installed prices for homes in County Antrim, including VAT. A survey sets the exact figure, because two similar-looking houses in Lisburn can need quite different radiators and pipework.

Winter daylight and heating in Lisburn
On the shortest day Lisburn gets only about 7 hours 16 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.
The steps for air source heat pump installation in Lisburn
- Send your postcode and a few details, or use the guide price tool.
- A surveyor visits your Lisburn home, measures every room and checks where the outdoor unit can go.
- You receive a heat loss design and a fixed written quote, with any grant shown where it applies.
- Installers fit the unit, cylinder and any radiator changes, typically over 2–4 days on site.
- The system is commissioned, set up with weather compensation and handed over with the paperwork.
Air source heat pump installation in Lisburn: questions
How long does a heat pump survey take in Lisburn?
A home survey in Lisburn 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 Lisburn?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Lisburn home states the expected time.
How soon can you survey a home in Lisburn?
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.
Will an air source heat pump be noisy?
Heat pumps are designed to run quietly, but where the unit sits makes a real difference. The survey looks for a position away from bedroom windows and neighbours, with clear airflow, and the installation must pass the MCS noise assessment. The fan is most noticeable on very cold days when the unit works hardest, and a little vapour during the periodic defrost is normal.
Do I need new radiators for a heat pump?
Not always; many homes keep most of their radiators and change only a few. Because a heat pump runs at a lower water temperature than a boiler, each radiator gives out less heat, so the survey checks every room against its heat loss. Rooms where the existing radiator falls short get a larger one, with a guide price of £250–£450 each, installed and including VAT.
