Before you book: air-to-air heat pumps in Cranleigh
Most homes can run on a heat pump if the system is designed properly, and Cranleigh is no different. The key is matching the heat pump and radiators to the home's heat loss.
Installers in Cranleigh plan condensate drains and pipe covers so indoor and outdoor runs stay neat. Top-floor rooms in Cranleigh that overheat in summer gain from the cooling an air-to-air system provides.
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.
- 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
- Homes where fitting radiators and pipework would be very disruptive
What's included
- Commissioning, MCS certificate and the air-to-air grant claim in England and Wales where eligible
- Electrical supply and controls set up for each room
- Free survey covering rooms to heat, unit positions and hot water options
- Refrigerant pipe runs to each indoor unit, made and charged by an F-gas certified engineer
- Outdoor unit and indoor units for each room
Extensions and garden rooms in Cranleigh 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
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 Cranleigh 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 costs around Cranleigh
These are guide prices for Surrey, installed and including VAT. Your final price is fixed in a written quote after the survey and depends on the heat loss of the house, the radiators that need changing and where the unit goes.
| 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.
Designing for Cranleigh's winters
Cranleigh sees roughly 7 hours 53 minutes of daylight in late December against 16 hours 34 minutes in June. Milder southern winters suit heat pumps well, though the system is still sized for a cold snap rather than an average day.

Air-to-air heat pumps in Cranleigh: questions
Do I need new radiators for a heat pump in Cranleigh?
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 Cranleigh home gives a room-by-room list.
How long does installation take in Cranleigh?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Cranleigh home states the expected time.
What size heat pump does a Cranleigh 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 Cranleigh 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.
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.
