How it works in Surbiton
Check the void
We confirm void depth, grid size and any obstructions such as beams, sprinkler pipes or ductwork. For sites in Surbiton 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
Void depth
Compact cassettes typically need around 250–300 mm of clear void; larger units need more. We measure before quoting.
Leased premises
If your Surbiton premises are leased, the landlord's written consent is usually needed for external units, wall penetrations and roof access. We provide drawings and data sheets for the request.
Cleaning access
Filters need cleaning regularly, so cassettes should be reachable with a step ladder.
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 Surbiton
- Gyms and leisure: high-capacity cooling and fresh air for gym floors, studios and changing rooms.
- Pubs and bars: cooling for busy bars, function rooms and cellars, sited with neighbours in mind.
- Healthcare and dental: clean, quiet cooling for surgeries, clinics, dental practices and care settings.
- Retail and shops: comfortable shop floors, stockrooms and entrances, even with the door open.
Compliance in England: refrigerant work falls under GB F-gas rules, and buildings with more than 12 kW of air conditioning in total need a periodic energy inspection (often called TM44).

At normal fan speeds modern cassettes are quiet enough for offices and restaurants. We select fan speeds and unit sizes so they are not working flat out.
