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 County Antrim.
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 property at survey.

Questions
What if my home is listed or in a conservation area?
If your home is listed, you will usually need listed building consent before fitting a heat pump, because the work can affect the building's character. In a conservation area, some positions, especially those facing a road, may need planning permission, depending on the rules in your nation. We check what applies at survey and suggest positions that keep the outdoor unit and pipework discreet. Older and protected homes can still suit a carefully designed heat pump.
Do air source heat pumps work in cold weather?
Yes, air source heat pumps are designed to keep working well below freezing and can heat your home through a UK winter. The system is sized for a cold design day in your area, so it is designed to cope on the coldest days. Efficiency falls as the outside temperature drops, and the unit periodically defrosts its outdoor coil, when a little vapour is normal. See how air source heat pumps work.
Can I have a heat pump in a flat or a small home?
Yes, many flats and small homes can have a heat pump, usually a smaller unit of around 4–5 kW. For a flat, the key questions are where the outdoor unit can go, such as a balcony, wall or yard, and whether the freeholder agrees. Flats may also need planning permission, depending on the rules in your nation, which we check at survey. In small homes the usual limit is cylinder space. Where a wet system will not fit, an air-to-air heat pump can heat individual rooms.
What is included in the guide price for a heat pump system?
Our full-system guide price covers the outdoor heat pump unit, a hot water cylinder, controls, commissioning and typical minor pipework. Extras are priced separately only when your home needs them: a replacement radiator sized for a heat pump is a guide price of £250–£450 each, and a pipework upgrade is typically £1,500–£3,500. All are guide prices, installed and including VAT. Your written quote lists exactly what is included before you decide.
