Air source heat pump installation in Belfast: what to expect
In Belfast, as anywhere in the UK, the heat pumps that perform well are the ones designed around low flow temperatures and sized from a proper heat loss calculation.
For older properties in Belfast, the heat loss calculation looks closely at solid walls, single glazing and draughts before any unit is sized. Terraced streets in Belfast 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
- Owners who want one contract covering design, fitting and paperwork
- Houses with reasonable insulation, or a plan to improve it
What's included
- Removal of the old boiler or heaters
- Free home survey and room-by-room heat loss calculation
- Radiator and pipework changes where the design needs them
- Outdoor unit, hot water cylinder and weather compensation controls
- Commissioning, handover and a walk-through of the controls
Installers working in Belfast plan the order of work so heating and hot water are off for as short a time as practical.
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 Belfast.
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 Belfast's winters
On the shortest day Belfast gets only about 7 hours 15 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.

Air source heat pump installation in Belfast: questions
Do I need new radiators for a heat pump in Belfast?
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 Belfast home gives a room-by-room list.
Can you service a heat pump in Belfast that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Belfast, whoever fitted them. Tell us the make and model when you book.
How long does a heat pump survey take in Belfast?
A home survey in Belfast 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.
Can I cancel after accepting the quote?
Nothing is ordered until you accept the written quote. Where the contract is agreed away from our premises, for example at your kitchen table, you can cancel within 14 days under the Consumer Contracts Regulations 2013. If you ask us to start sooner and then cancel, you pay only for work done up to that point.
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.
