How we work in Southampton
Check the void
We confirm void depth, grid size and any obstructions such as beams, sprinkler pipes or ductwork. For sites in Southampton 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.
What to think about in Southampton
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.
Condensate
Most cassettes include a pump. The discharge still needs a route to a drain, which we design at survey.
Conservation areas
Historic streets and listed buildings in and around Southampton are more likely to need planning permission for outdoor units on visible elevations. We check with the local planning authority before work is booked.
Typical premises in Southampton
- Gyms and leisure: high-capacity cooling and fresh air for gym floors, studios and changing rooms.
- Schools and education: classroom cooling, ventilation and IT room cooling, installed in the holidays.
- 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.
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).

Which postcodes do you cover in Southampton?
All of them, including SO15. Give us your postcode when you enquire and we will confirm the visit details.
What size cassette do I need?
It depends on the heat load. As a guide, a compact cassette suits a room of up to about 40–50 m² of office space; larger spaces use bigger units or several cassettes.
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.
