The steps for a project in London
Check the void
We confirm void depth, grid size and any obstructions such as beams, sprinkler pipes or ductwork. For sites in London 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.
Things to check in London
Cleaning access
Filters need cleaning regularly, so cassettes should be reachable with a step ladder.
Access and parking
Town-centre jobs in London often come down to access — loading restrictions, parking for the van and getting equipment onto a roof. We check this at survey and plan deliveries around it.
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 London are more likely to need planning permission for outdoor units on visible elevations. We check with the local planning authority before work is booked.
Premises we work in around London
- Offices: zoned cooling and heating for open-plan floors, meeting rooms and comms rooms.
- Retail and shops: comfortable shop floors, stockrooms and entrances, even with the door open.
- Pubs and bars: cooling for busy bars, function rooms and cellars, sited with neighbours in mind.
- Schools and education: classroom cooling, ventilation and IT room cooling, installed in the holidays.
Two rules matter for most businesses in England: GB F-gas rules (leak checks from 5 tonnes CO2e) and the periodic energy inspection for more than 12 kW of air conditioning.
Common questions from businesses in London
How much does a ceiling cassette cost in London?
Guide prices in London run from about £2,750 to £6,350 per cassette, plus VAT. A typical job (shop or restaurant with 2–3 cassettes) costs £6,350–£17,295 plus VAT. We fix the price in writing after a free survey.
Do you also cover Surrey, Hertfordshire and Essex?
Yes. Alongside London, we also cover Surrey, Hertfordshire and Essex. Each has its own page with local guide prices.
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.
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.
