Postcode districts we cover include BN5, BN14, BN42, BN99, PO10, PO22, RH14 and RH77. In West Sussex, outdoor unit positions are often the deciding factor: a rear flat roof or yard is usually straightforward, while a front elevation may need landlord or planning consent first.

From enquiry to handover in West Sussex
Check the void
We confirm void depth, grid size and any obstructions such as beams, sprinkler pipes or ductwork. For sites in West Sussex we confirm access and parking beforehand.
Set positions
Cassettes are placed against the lighting and grid layout so air reaches the whole space.
Hang and connect
Units are hung on drop rods, connected to pipework and the condensate line.
Test and commission
The condensate pump is water-tested, the system pressure tested and charged, and air directions set.
Local points to consider
Cleaning access
Filters need cleaning regularly, so cassettes should be reachable with a step ladder.
Roof and height work
Flat roofs, high walls and atriums need the right access equipment and edge protection. We plan towers, MEWPs or scaffold before the job, not on the day.
Void depth
Compact cassettes typically need around 250–300 mm of clear void; larger units need more. We measure before quoting.
Shared buildings
In multi-let buildings, roof space, risers and plant areas are often controlled by a managing agent. We work to their permits and method-statement requirements.
Types of premises we cover in West Sussex
- Pubs and bars: cooling for busy bars, function rooms and cellars, sited with neighbours in mind.

In England, systems holding 5 tonnes CO2 equivalent of refrigerant or more fall under GB F-gas rules, with regular leak checks and records; buildings with more than 12 kW of air conditioning in total also need a periodic energy inspection.
Common questions from businesses in West Sussex
How much does a ceiling cassette cost in West Sussex?
Guide prices in West Sussex run from about £2,450 to £5,695 per cassette, plus VAT. A typical job (shop or restaurant with 2–3 cassettes) costs £5,695–£15,500 plus VAT. We fix the price in writing after a free survey.
Do you also cover East Sussex, Surrey and Hampshire?
Yes. Alongside West Sussex, we also cover East Sussex, Surrey and Hampshire. Each has its own page with local guide prices.
Do I need a suspended ceiling for a cassette?
Yes, or a ceiling void with access. In solid ceilings a wall-mounted or ducted unit is usually the better option.
Can a cassette bring in fresh air?
Many cassettes have a knock-out for a fresh-air duct, so ventilation air can be connected. The ventilation system still needs designing separately.
