How it works in Blackheath
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 Blackheath 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.
Points to plan for in Blackheath
Ceiling grid
Compact cassettes drop into a 600 mm grid; full-size units need the grid adapting around a larger panel.
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.
Conservation areas
Historic streets and listed buildings in and around Blackheath are more likely to need planning permission for outdoor units on visible elevations. We check with the local planning authority before work is booked.

Which postcodes do you cover in Blackheath?
All of them, including B65, CO2, GU4 and IP19. Give us your postcode when you enquire and we will confirm the visit details.
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.
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.
