Air-to-air heat pumps in Bromley: what to expect
Homes around Bromley range from older terraces to newer estates, and each needs a different design. That is why we survey before we quote.
Flats in Bromley on storage or panel heaters can often switch to air-to-air without fitting radiators or pipework. Top-floor rooms in Bromley 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
- Extensions, conservatories and garden rooms
- Flats and apartments with storage or panel heaters
What's included
- Outdoor unit and indoor units for each room
- Electrical supply and controls set up for each room
- Commissioning, MCS certificate and the air-to-air grant claim in England and Wales where eligible
- Condensate drains and neat external pipe covers
- Refrigerant pipe runs to each indoor unit, made and charged by an F-gas certified engineer
Extensions and garden rooms in Bromley 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 Bromley 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.
What to budget for air-to-air heat pumps in Bromley
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 Bromley 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.
Short winter days in Bromley and what they mean
Bromley 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.

- On installation days the old system is removed and the new one fitted and filled.
- We commission the heat pump, show you the controls and register the installation.
Air-to-air heat pumps in Bromley: questions
Do I need new radiators for a heat pump in Bromley?
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 Bromley home gives a room-by-room list.
What size heat pump does a Bromley 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 Bromley home.
How soon can you survey a home in Bromley?
Survey dates depend on how busy installers are in Greater London. We offer the next available dates when you enquire and confirm them in writing.
Are air-to-air heat pumps suitable for flats?
Often, yes. They need no radiators, pipework or cylinder, so they suit flats heated by storage or panel heaters. You need a position for the outdoor unit, such as a balcony, wall bracket or ground-floor yard, and leaseholders normally need the freeholder's or management company's consent. Planning rules for flats differ by nation, so we check what applies at survey.
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.
