The steps for a project in Chalfont St Peter
Check the void
We confirm void depth, grid size and any obstructions such as beams, sprinkler pipes or ductwork. For sites in Chalfont St Peter 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.
Points to plan for in Chalfont St Peter
Condensate
Most cassettes include a pump. The discharge still needs a route to a drain, which we design at survey.
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.
Void depth
Compact cassettes typically need around 250–300 mm of clear void; larger units need more. We measure before quoting.
Working hours
Most Chalfont St Peter businesses prefer noisy work outside trading hours. Early starts, evenings and weekends can be arranged and are priced up front.

Many cassettes have a knock-out for a fresh-air duct, so ventilation air can be connected. The ventilation system still needs designing separately.
