What to know about air-to-air heat pumps in Morden
Every property in Morden 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.
Installers in Morden plan condensate drains and pipe covers so indoor and outdoor runs stay neat. Extensions and garden rooms in Morden that are hard to connect to the main heating can have their own air-to-air unit.
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
- Flats and apartments with storage or panel heaters
- Homes where fitting radiators and pipework would be very disruptive
What's included
- Free survey covering rooms to heat, unit positions and hot water options
- Outdoor unit and indoor units for each room
- Condensate drains and neat external pipe covers
- Refrigerant pipe runs to each indoor unit, made and charged by an F-gas certified engineer
- Electrical supply and controls set up for each room
A survey in Morden covers indoor unit positions, pipe routes and hot water for homes across Greater London.
Grants and rules for heat pumps in England
Homes in Morden 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.
What to budget for air-to-air heat pumps in Morden
The ranges below are typical installed prices for homes in Greater London, including VAT. A survey sets the exact figure, because two similar-looking houses in Morden can need quite different radiators and pipework.
| System | Installed guide price |
|---|---|
| Air-to-air heat pump, 1–2 rooms | £2,700–£5,600 |
| Air-to-air heat pump, multi-room 3–4 bedroom home | £4,500–£8,950 |
Installed, inc VAT. Air-to-air systems heat (and can cool) rooms but do not provide hot water. In England and Wales the Boiler Upgrade Scheme gives £2,500 towards an air-to-air system in a home, deducted from your quote where eligible.
Winter daylight and heating in Morden
On the shortest day Morden gets about 7 hours 51 minutes of daylight, and the winter sun reaches only around 15° above the horizon at noon. Winters this far south are milder than in most of the UK, which helps a heat pump run at low flow temperatures for much of the season.

Air-to-air heat pumps in Morden: questions
Do I need new radiators for a heat pump in Morden?
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 Morden home gives a room-by-room list.
How long does a heat pump survey take in Morden?
A home survey in Morden usually takes one to two hours. The surveyor measures every heated room, checks windows, walls and radiators, and looks at where the outdoor unit and cylinder can go.
Where would the outdoor unit go on a Morden 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 Morden home.
Can air-to-air heat pumps cool as well as heat?
Yes. Most air-to-air systems can reverse their cycle to cool and dehumidify rooms in summer, which makes them useful for loft rooms, south-facing extensions and home offices that overheat. Cooling uses electricity, so running costs rise if it is used heavily. You control heating and cooling for each room separately.
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.
