Air-to-air heat pumps in Sandwich: what to expect
In Sandwich, as anywhere in the UK, the heat pumps that perform well are the ones designed around low flow temperatures and sized from a proper heat loss calculation.
Top-floor rooms in Sandwich that overheat in summer gain from the cooling an air-to-air system provides. Installers in Sandwich plan condensate drains and pipe covers so indoor and outdoor runs stay neat.
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.
- Homes where fitting radiators and pipework would be very disruptive
- Households that already have, or will add, a separate source of hot water
- Rooms that get too hot in summer as well as cold in winter
What's included
- Commissioning, MCS certificate and the air-to-air grant claim in England and Wales where eligible
- 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
For terraced homes in Sandwich, the outdoor unit can often sit in a rear yard with tidy pipe runs to each room.
Grants and rules for heat pumps in England
In England the Boiler Upgrade Scheme gives £7,500 towards an air source heat pump (£9,000 if it replaces oil or LPG, from 21 July 2026 to 31 March 2027), and since 28 April 2026 a valid EPC is no longer needed. The grant is applied for by the MCS-certified installer and shown as a deduction on your Sandwich quote.
Installing heat pumps is zero-rated for VAT across the UK until 31 March 2027. Since 29 May 2025, permitted development in England allows up to two air source heat pumps on a house, each up to 1.5 m³, with no blanket 1 m boundary rule — the installation must still meet the MCS planning standards, including the noise check. Listed buildings, flats and some conservation-area positions need extra consent, which we check at survey.
Air-to-air heat pumps prices in Sandwich
Guide prices for Sandwich and the rest of Kent are shown below, installed and inc VAT. We publish ranges rather than a single figure because design details move the price, and the written quote after survey fixes it.
| System | Installed guide price |
|---|---|
| Air-to-air heat pump, 1–2 rooms | £2,450–£5,150 |
| Air-to-air heat pump, multi-room 3–4 bedroom home | £4,100–£8,250 |
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 Sandwich?
On the shortest day Sandwich 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 Sandwich: questions
Where would the outdoor unit go on a Sandwich 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 Sandwich home.
What size heat pump does a Sandwich 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 Sandwich home.
Do I need new radiators for a heat pump in Sandwich?
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 Sandwich home gives a room-by-room list.
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.
