What to know about air-to-air heat pumps in Petworth
Homes around Petworth range from older terraces to newer estates, and each needs a different design. That is why we survey before we quote.
Flats in Petworth on storage or panel heaters can often switch to air-to-air without fitting radiators or pipework. A survey in Petworth covers indoor unit positions, pipe routes and hot water for homes across West Sussex.
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
- Commissioning, MCS certificate and the air-to-air grant claim in England and Wales where eligible
- Refrigerant pipe runs to each indoor unit, made and charged by an F-gas certified engineer
- Outdoor unit and indoor units for each room
- Free survey covering rooms to heat, unit positions and hot water options
For terraced homes in Petworth, 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
Homes in Petworth 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.
What to budget for air-to-air heat pumps in Petworth
The ranges below are typical installed prices for homes in West Sussex, including VAT. A survey sets the exact figure, because two similar-looking houses in Petworth can need quite different radiators and pipework.
| System | Installed guide price |
|---|---|
| Air-to-air heat pump, 1–2 rooms | £2,500–£5,200 |
| Air-to-air heat pump, multi-room 3–4 bedroom home | £4,150–£8,300 |
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.
Winter daylight and heating in Petworth
On the shortest day Petworth gets about 7 hours 55 minutes of daylight, and the winter sun reaches only around 16° above the horizon at noon. Winters this far south are milder than in most of the UK, which helps a heat pump run at low flow temperatures for much of the season.

Air-to-air heat pumps in Petworth: questions
How long does a heat pump survey take in Petworth?
A home survey in Petworth 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.
Do I need new radiators for a heat pump in Petworth?
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 Petworth home gives a room-by-room list.
Can you service a heat pump in Petworth that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Petworth, whoever fitted them. Tell us the make and model when you book.
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.
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.
