How we work in New Malden
Check the void
We confirm void depth, grid size and any obstructions such as beams, sprinkler pipes or ductwork. For sites in New Malden 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 New Malden
Condensate
Most cassettes include a pump. The discharge still needs a route to a drain, which we design at survey.
Leased premises
If your New Malden 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.
Neighbours and noise
Outdoor units near flats — common above shops — need careful siting so noise at neighbours' windows stays low. We choose positions and quieter units with that in mind.
Premises we work in around New Malden
- Healthcare and dental: clean, quiet cooling for surgeries, clinics, dental practices and care settings.

In England, systems holding 5 tonnes CO2 equivalent of refrigerant or more fall under GB F-gas rules, with regular leak checks and records; buildings with more than 12 kW of air conditioning in total also need a periodic energy inspection.

Which postcodes do you cover in New Malden?
All of them, including KT3. 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.
