Air source heat pump installation for Coleraine homes
Most homes can run on a heat pump if the system is designed properly, and Coleraine is no different. The key is matching the heat pump and radiators to the home's heat loss.
Terraced streets in Coleraine often mean a compact unit position at the rear, so siting and sound levels are checked carefully. For older properties in Coleraine, the heat loss calculation looks closely at solid walls, single glazing and draughts before any unit is sized.
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.
- Households with room for a hot water cylinder
- Houses with reasonable insulation, or a plan to improve it
- Owners who want one contract covering design, fitting and paperwork
What's included
- Radiator and pipework changes where the design needs them
- Commissioning, handover and a walk-through of the controls
- MCS registration and certificate, plus network operator notification
- Free home survey and room-by-room heat loss calculation
- Removal of the old boiler or heaters
Many homes in Coleraine have a side passage or rear garden with room for an outdoor unit, and the survey checks airflow and distance from neighbouring windows.
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.

- 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.
Air source heat pump installation in Coleraine: questions
Can you service a heat pump in Coleraine that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Coleraine, whoever fitted them. Tell us the make and model when you book.
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.
What size heat pump does a Coleraine 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 Coleraine home.
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.
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.
