Air-to-air heat pumps in Durham: what to expect
Every property in Durham is different, so the design starts from measurements rather than a rule of thumb. That keeps the system the right size and the running costs predictable.
Flats in Durham on storage or panel heaters can often switch to air-to-air without fitting radiators or pipework. For terraced homes in Durham, the outdoor unit can often sit in a rear yard with tidy pipe runs to each room.
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.
- Extensions, conservatories and garden rooms
- Homes where fitting radiators and pipework would be very disruptive
- Flats and apartments with storage or panel heaters
What's included
- Commissioning, MCS certificate and the air-to-air grant claim in England and Wales where eligible
- Condensate drains and neat external pipe covers
- Refrigerant pipe runs to each indoor unit, made and charged by an F-gas certified engineer
- Free survey covering rooms to heat, unit positions and hot water options
- Outdoor unit and indoor units for each room
Extensions and garden rooms in Durham that are hard to connect to the main heating can have their own air-to-air unit.
Grants and rules for heat pumps in England
Homes in Durham can use the Boiler Upgrade Scheme, which takes £7,500 off the cost of an air source heat pump when it replaces fossil-fuel or electric heating. Replacing oil or LPG heating qualifies for £9,000 for installations from 21 July 2026 to 31 March 2027, and air-to-air systems for £2,500. The MCS-certified installer named in your quote applies for the grant and deducts it from the price.
There is no VAT on installing a heat pump anywhere in the UK until 31 March 2027. In England most houses can have an air source heat pump under permitted development, provided the unit meets the MCS noise and siting standards; the old 1 m boundary limit was removed on 29 May 2025. We flag listed buildings, flats and sensitive conservation-area positions at survey.

Designing for Durham's winters
Durham sees roughly 7 hours 13 minutes of daylight in December and 17 hours 19 minutes in June. With a longer heating season than the south, the gains from low flow temperatures and good controls add up over the year.

Air-to-air heat pumps in Durham: questions
How long does installation take in Durham?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Durham home states the expected time.
Do I need new radiators for a heat pump in Durham?
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 Durham home gives a room-by-room list.
Where would the outdoor unit go on a Durham house?
Usually at the side or rear, on a level base with space around it for airflow and servicing, away from bedroom windows where possible. The surveyor checks positions at your Durham home.
How do I look after an air-to-air system?
Clean the indoor unit filters regularly, typically every few weeks during heavy use and following the manufacturer's guidance, and keep the outdoor unit clear of leaves and snow. Annual servicing is recommended and is often a condition of the manufacturer's warranty. Any work on the refrigerant circuit must be done by an F-gas certified engineer.
Are air-to-air heat pumps suitable for flats?
Often, yes. They need no radiators, pipework or cylinder, so they suit flats heated by storage or panel heaters. You need a position for the outdoor unit, such as a balcony, wall bracket or ground-floor yard, and leaseholders normally need the freeholder's or management company's consent. Planning rules for flats differ by nation, so we check what applies at survey.
