What to know about air-to-air heat pumps in Southgate
Every property in Southgate is different, so the design starts from measurements rather than a rule of thumb. That keeps the system the right size and the running costs predictable.
A survey in Southgate covers indoor unit positions, pipe routes and hot water for homes across Greater London. Installers in Southgate 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.
- Rooms that get too hot in summer as well as cold in winter
- Flats and apartments with storage or panel heaters
- Extensions, conservatories and garden rooms
What's included
- Refrigerant pipe runs to each indoor unit, made and charged by an F-gas certified engineer
- Electrical supply and controls set up for each room
- Condensate drains and neat external pipe covers
- Outdoor unit and indoor units for each room
- Commissioning, MCS certificate and the air-to-air grant claim in England and Wales where eligible
Extensions and garden rooms in Southgate 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 Southgate 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.
Air-to-air heat pumps costs around Southgate
Guide prices for Southgate 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 Southgate?
Southgate has about 7 hours 48 minutes of daylight at midwinter and 16 hours 40 minutes at midsummer. That swing matters if you pair a heat pump with solar panels: summer generation can cover much of the hot water, winter generation far less.

Air-to-air heat pumps in Southgate: questions
Do you cover Enfield as well as Southgate?
Yes. We arrange surveys and installation in Enfield, which is about 2 miles north-east of Southgate, and across Greater London.
How soon can you survey a home in Southgate?
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.
How long does installation take in Southgate?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Southgate 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 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.
