About our air conditioning in East Hampnett
We approach an installation much as a doctor approaches a patient: survey first, install second, commission and hand over last. The sign-off includes testing every mode, showing you the controls and handing over the F-Gas records. A lot of the calls we get from East Hampnett are about one room that is too hot to sleep or work in. That’s normally a single wall-mounted split, from £1,200 + VAT.
A single room takes a day in most homes, with multi-room systems taking longer depending on pipe routes, and we leave the room clean and the controls explained.
In a village like East Hampnett, many homes are older, and some are listed. We check that first, because permitted development doesn’t apply within the grounds of a listed building.
Each manufacturer sets its own warranty period. Daikin, for example, gives a standard 2 years on split air conditioning, with longer extensions only on its air-to-water heat pumps. For any other brand, we explain the manufacturer’s terms on your quote.

What an install looks like in East Hampnett
VOA council tax data show about 35% of homes across East Hampnett and its surrounding area were built in 2000 or later, and about 71% of households live in detached or semi-detached houses, according to the 2021 Census. Newer homes usually have cavity walls and loft space that make pipe runs easier, though some estates have planning conditions or covenants worth checking. Detached and semi-detached houses normally have space for the outdoor unit, and several rooms can share one on a multi-split.
Living close to The Parish Church of St Mary? Some older properties in parts like that are protected, and the survey finds out whether yours is. About 2.4 miles north-west stands Goodwood House. Listed homes in any area need consent first, so tell us if yours is one.

Questions from East Hampnett
Do I need planning permission for air conditioning in East Hampnett?
That depends on the building and where the outdoor unit goes. Around 10 listed entries sit within 0.5 miles of central East Hampnett. Since 2025, an air-to-air heat pump on a house can count as permitted development if it meets the conditions and is not used only for cooling. Listed buildings still need consent, and in a conservation area a road-facing wall or roof isn’t allowed under those rules. If there’s any doubt, we ask the local planning authority (for East Hampnett, normally Chichester council).
Is East Hampnett within the area you cover?
Yes, and the size of the place makes no difference to how we work. Send a few details and pictures, and we reply the same working day.
Do you work for landlords and businesses?
Yes. From one rented home to commercial buildings, the approach is the same: survey or diagnosis, a fixed price and proper paperwork.
Can I fit air conditioning or a heat pump myself?
The refrigerant side has to be done by a qualified engineer working for an F-Gas certified company. That’s the law, not just our preference, and manufacturers expect it for their warranty too. We are happy to quote for the full job, supply to commissioning.
What does it cost to install air conditioning?
For one room, a split system is typically £1,200–£2,200 + VAT. Two rooms on a multi-split are typically £2,800–£4,500 + VAT, and three to five rooms £4,500–£8,500 + VAT, including supply, installation, commissioning and F-Gas documentation. The price is fixed before we start.
Is there a survey before the work?
Yes. For simple jobs, photos and a few details can be enough, while larger systems and faults that need testing are seen on site.
Can we book visits on a schedule?
Yes. Send details of the systems and how they’re used and we’ll propose a schedule and quote for it. That can include the leak checks the F-gas rules require for larger systems.
What owners can safely do
Do not move, re-route or disconnect units or pipework yourself. Moving a unit involves the refrigerant circuit, so it needs an F-Gas qualified engineer, and the electrics need care too. Ask us to quote for a move instead.
Owner care supports servicing; it doesn’t replace it. Clean filters and a clear outdoor unit help the system run as it should, but the refrigerant circuit, the electrics and the parts you can’t see still need an engineer at the interval the manufacturer recommends.
What we do, step by step
Protection comes first: dust sheets over floors and furniture near the work and nothing is moved without asking you. Then the electrics are made safe and the work begins. The work on site takes about a day for a single-room system, longer for multi-room and ducted systems, and we clear up before we go. For a place like East Hampnett, the timing is set with you and the travel is our side of the planning.
- First the diagnosis: a survey of the rooms, the walls, the outside and the electrics.
- Next, a recommendation for each room and a fixed price.
- The treatment: units fitted, pipework and drain routed, and the electrics installed.
- Testing: the circuit is pressure tested and evacuated before the refrigerant is released.
- The sign-off: commissioning, a walk through the controls, and the F-Gas records and warranty details.
How to prepare
- Mention any parking restrictions near the property
- Tell us about access, such as roof hatches, high walls or locked plant areas
- Let us know where the consumer unit is
