What to know about air-to-air heat pumps in Harlow
The question for a Harlow 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.
Top-floor rooms in Harlow that overheat in summer gain from the cooling an air-to-air system provides. A survey in Harlow covers indoor unit positions, pipe routes and hot water for homes across Essex.
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.
- Extensions, conservatories and garden rooms
- Homes where fitting radiators and pipework would be very disruptive
- Flats and apartments with storage or panel heaters
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
- Condensate drains and neat external pipe covers
- Outdoor unit and indoor units for each room
- Electrical supply and controls set up for each room
For terraced homes in Harlow, 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 Harlow 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 Harlow
Guide prices for Harlow and the rest of Essex 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.

| 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.
Short winter days in Harlow and what they mean
On the shortest day Harlow gets about 7 hours 47 minutes of daylight, with the noon sun around 15° up. The heating season runs from autumn into spring, so a heat pump that is sized correctly and set up with weather compensation does most of its work in steady, cool conditions.

Air-to-air heat pumps in Harlow: questions
Where would the outdoor unit go on a Harlow 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 Harlow home.
How long does installation take in Harlow?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Harlow home states the expected time.
How long does a heat pump survey take in Harlow?
A home survey in Harlow usually takes one to two hours. The surveyor measures every heated room, checks windows, walls and radiators, and looks at where the outdoor unit and cylinder can go.
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.
