How it works in High Wycombe
Check the void
We confirm void depth, grid size and any obstructions such as beams, sprinkler pipes or ductwork.
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. We keep work areas in High Wycombe screened and tidy at the end of each day.
Test and commission
The condensate pump is water-tested, the system pressure tested and charged, and air directions set.
Things to check in High Wycombe
Void depth
Compact cassettes typically need around 250–300 mm of clear void; larger units need more. We measure before quoting.
Conservation areas
Historic streets and listed buildings in and around High Wycombe are more likely to need planning permission for outdoor units on visible elevations. We check with the local planning authority before work is booked.
Ceiling grid
Compact cassettes drop into a 600 mm grid; full-size units need the grid adapting around a larger panel.
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.

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.
