Air-to-air heat pumps in Littlehampton: what to expect
Every property in Littlehampton 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 Littlehampton covers indoor unit positions, pipe routes and hot water for homes across West Sussex. For terraced homes in Littlehampton, 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.
- Homes where fitting radiators and pipework would be very disruptive
- Extensions, conservatories and garden rooms
- Households that already have, or will add, a separate source of hot water
What's included
- Outdoor unit and indoor units for each room
- 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
- Free survey covering rooms to heat, unit positions and hot water options
- Electrical supply and controls set up for each room
Installers in Littlehampton plan condensate drains and pipe covers so indoor and outdoor runs stay neat.
Grants and rules for heat pumps in England
Homes in Littlehampton 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.
Guide prices for air-to-air heat pumps in Littlehampton
Here are typical prices for air-to-air heat pumps in West Sussex, installed and including VAT. Use the guide price tool for a figure based on your home, then a survey confirms it in writing.
| 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.
Short winter days in Littlehampton and what they mean
Littlehampton sees roughly 7 hours 56 minutes of daylight in late December against 16 hours 31 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.

Air-to-air heat pumps in Littlehampton: questions
Can you service a heat pump in Littlehampton that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Littlehampton, whoever fitted them. Tell us the make and model when you book.
Where would the outdoor unit go on a Littlehampton 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 Littlehampton home.
How long does installation take in Littlehampton?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Littlehampton home states the expected time.
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.
