What to know about air-to-air heat pumps in Derry/Londonderry
Most homes can run on a heat pump if the system is designed properly, and Derry/Londonderry is no different. The key is matching the heat pump and radiators to the home's heat loss.
Top-floor rooms in Derry/Londonderry that overheat in summer gain from the cooling an air-to-air system provides. A survey in Derry/Londonderry covers indoor unit positions, pipe routes and hot water for homes across County Londonderry.
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
- Rooms that get too hot in summer as well as cold in winter
- Households that already have, or will add, a separate source of hot water
What's included
- Refrigerant pipe runs to each indoor unit, made and charged by an F-gas certified engineer
- Condensate drains and neat external pipe covers
- Outdoor unit and indoor units for each room
- Electrical supply and controls set up for each room
- Free survey covering rooms to heat, unit positions and hot water options
Flats in Derry/Londonderry on storage or panel heaters can often switch to air-to-air without fitting radiators or pipework.
Grants and rules for heat pumps in Northern Ireland
The Boiler Upgrade Scheme covers England and Wales only, and there is currently no dedicated heat pump grant for homeowners in Northern Ireland. Our quote for a Derry/Londonderry home is therefore shown without a grant deduction; if support becomes available we will tell you how it applies.
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 Derry/Londonderry property at survey.

Air-to-air heat pumps in Derry/Londonderry: questions
Do you cover Limavady as well as Derry/Londonderry?
Yes. We arrange surveys and installation in Limavady, which is about 15 miles east of Derry/Londonderry, and across County Londonderry.
How long does a heat pump survey take in Derry/Londonderry?

How soon can you survey a home in Derry/Londonderry?
Survey dates depend on how busy installers are in County Londonderry. We offer the next available dates when you enquire and confirm them in writing.
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.
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.
