Air-to-air heat pumps in Hailsham: what to expect
The question for a Hailsham 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.
Extensions and garden rooms in Hailsham that are hard to connect to the main heating can have their own air-to-air unit. For terraced homes in Hailsham, the outdoor unit can often sit in a rear yard with tidy pipe runs to each room.
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.
- Flats and apartments with storage or panel heaters
- Households that already have, or will add, a separate source of hot water
- Extensions, conservatories and garden rooms
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
- Outdoor unit and indoor units for each room
- Condensate drains and neat external pipe covers
- Refrigerant pipe runs to each indoor unit, made and charged by an F-gas certified engineer
Flats in Hailsham on storage or panel heaters can often switch to air-to-air without fitting radiators or pipework.
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 Hailsham 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 Hailsham
The ranges below are typical installed prices for homes in East Sussex, including VAT. A survey sets the exact figure, because two similar-looking houses in Hailsham can need quite different radiators and pipework.
| System | Installed guide price |
|---|---|
| Air-to-air heat pump, 1–2 rooms | £2,450–£5,150 |
| 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 Hailsham and what they mean
On the shortest day Hailsham gets about 7 hours 56 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 Hailsham: questions
Do I need new radiators for a heat pump in Hailsham?
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 Hailsham home gives a room-by-room list.
Where would the outdoor unit go on a Hailsham 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 Hailsham home.
How soon can you survey a home in Hailsham?
Survey dates depend on how busy installers are in East Sussex. We offer the next available dates when you enquire and confirm them in writing.
Is there a grant for air-to-air heat pumps?
In England and Wales, yes: the Boiler Upgrade Scheme includes a grant of £2,500 for air-to-air heat pumps in homes, from 28 April 2026. The MCS-certified installer applies to Ofgem and deducts it from your quote, subject to the scheme's conditions. The scheme does not cover Scotland or Northern Ireland; in Scotland, Home Energy Scotland has its own rules.
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.
