Air-to-air heat pumps for Redhill homes
The question for a Redhill home is rarely whether a heat pump can work, but what needs to change to make it work well: radiator sizes, pipework, controls and where the unit goes.
Installers in Redhill plan condensate drains and pipe covers so indoor and outdoor runs stay neat. Extensions and garden rooms in Redhill 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.
- Flats and apartments with storage or panel heaters
- Extensions, conservatories and garden rooms
- Households that already have, or will add, a separate source of hot water
What's included
- Free survey covering rooms to heat, unit positions and hot water options
- Commissioning, MCS certificate and the air-to-air grant claim in England and Wales where eligible
- Outdoor unit and indoor units for each room
- Condensate drains and neat external pipe covers
- Electrical supply and controls set up for each room
Top-floor rooms in Redhill that overheat in summer gain from the cooling an air-to-air system provides.
Grants and rules for heat pumps in England
Homes in Redhill 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.
Air-to-air heat pumps prices in Redhill
The ranges below are typical installed prices for homes in Surrey, including VAT. A survey sets the exact figure, because two similar-looking houses in Redhill can need quite different radiators and pipework.
| System | Installed guide price |
|---|---|
| Air-to-air heat pump, 1–2 rooms | £2,550–£5,350 |
| Air-to-air heat pump, multi-room 3–4 bedroom home | £4,300–£8,550 |
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.
How long is the heating season in Redhill?
On the shortest day Redhill gets about 7 hours 52 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 Redhill: questions
How soon can you survey a home in Redhill?
Survey dates depend on how busy installers are in Surrey. We offer the next available dates when you enquire and confirm them in writing.
Where would the outdoor unit go on a Redhill 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 Redhill home.
What size heat pump does a Redhill 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 Redhill home.
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.
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.
