Air-to-air heat pumps in Holywood: what to expect
Homes around Holywood range from older terraces to newer estates, and each needs a different design. That is why we survey before we quote.
Flats in Holywood on storage or panel heaters can often switch to air-to-air without fitting radiators or pipework. A survey in Holywood covers indoor unit positions, pipe routes and hot water for homes across County Down.
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.
- Flats and apartments with storage or panel heaters
- Extensions, conservatories and garden rooms
- 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
- Condensate drains and neat external pipe covers
- Electrical supply and controls set up for each room
- Outdoor unit and indoor units for each room
- Refrigerant pipe runs to each indoor unit, made and charged by an F-gas certified engineer
For terraced homes in Holywood, the outdoor unit can often sit in a rear yard with tidy pipe runs to each room.
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 Holywood.
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 Holywood property at survey.
What to budget for air-to-air heat pumps in Holywood
These are guide prices for County Down, installed and including VAT. Your final price is fixed in a written quote after the survey and depends on the heat loss of the house, the radiators that need changing and where the unit goes.
| System | Installed guide price |
|---|---|
| Air-to-air heat pump, 1–2 rooms | £2,350–£4,850 |
| 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.
Winter daylight and heating in Holywood
On the shortest day Holywood gets only about 7 hours 14 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-to-air heat pumps in Holywood
- Tell us about your home: postcode, property type and current heating.
- We book a survey in Holywood; the surveyor measures rooms, windows and radiators and looks at cylinder space.
- 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-to-air heat pumps in Holywood: questions
How long does installation take in Holywood?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Holywood home states the expected time.
What size heat pump does a Holywood 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 Holywood home.
How soon can you survey a home in Holywood?
Survey dates depend on how busy installers are in County Down. We offer the next available dates when you enquire and confirm them in writing.
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.
Is there a grant for air-to-air heat pumps?
In England and Wales, yes: the Boiler Upgrade Scheme includes a grant of £2,500 for air-to-air heat pumps in homes, from 28 April 2026. The MCS-certified installer applies to Ofgem and deducts it from your quote, subject to the scheme's conditions. The scheme does not cover Scotland or Northern Ireland; in Scotland, Home Energy Scotland has its own rules.
