Air-to-air heat pumps in Croydon: what to expect
In Croydon, 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.
Flats in Croydon on storage or panel heaters can often switch to air-to-air without fitting radiators or pipework. A survey in Croydon covers indoor unit positions, pipe routes and hot water for homes across Greater London.
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.
- 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
- Flats and apartments with storage or panel heaters
What's included
- Condensate drains and neat external pipe covers
- Free survey covering rooms to heat, unit positions and hot water options
- Outdoor unit and indoor units for each room
- Electrical supply and controls set up for each room
- Refrigerant pipe runs to each indoor unit, made and charged by an F-gas certified engineer
Extensions and garden rooms in Croydon 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 Croydon 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.
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.
Guide prices for air-to-air heat pumps in Croydon
Guide prices for Croydon and the rest of Greater London 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 | £2,700–£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.
How long is the heating season in Croydon?
Croydon sees roughly 7 hours 51 minutes of daylight in late December against 16 hours 37 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 Croydon: questions
What size heat pump does a Croydon 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 Croydon home.
Where would the outdoor unit go on a Croydon 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 Croydon home.
How long does installation take in Croydon?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Croydon home states the expected time.
How much sound do the indoor units make?
Indoor units are designed to run quietly, with a fan you will hear most when heating or cooling at full output. Lower fan settings and night modes reduce sound in bedrooms. Siting matters for the outdoor unit too: it needs airflow and a position that passes the MCS noise assessment. Ask to see the sound levels of the proposed units at survey.
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.
