Ducted air conditioning uses an indoor unit hidden in the ceiling void or a plant space, connected by ductwork to grilles or slot diffusers in the room.
London and surrounding areas
We cover all of London, including Brent, Islington, Bexley, Barking and Sutton. Each town below has its own page with local guide prices.
Postcode districts we cover include BR1, E16, EN5, N16, SE7, SW8, W1 and WC2R. Buildings across London range from converted period offices to modern units with deep ceiling voids, so we measure each site rather than relying on a standard package.
What we do
- Survey of void depth and duct routes
- Supply and return ductwork, plenums and grilles
- Access panel for servicing
- Pipework, condensate and controls
- Air-flow balancing and commissioning

From enquiry to handover in London
Survey and route
We check void depths and plan routes for supply and return ductwork.
Design the air side
Grille sizes and positions are chosen for even air flow and low noise.
Install unit and ducts
The unit is hung with access for servicing; ductwork and grilles are fitted. In London we agree timings around your opening hours.
Balance and commission
Air flows are measured and balanced, then the system is commissioned.
What to think about in London
Return air
Every ducted unit needs a return air path; we design it rather than rely on gaps under doors.
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.
Void depth
Low-profile ducted units can fit voids of around 250 mm, but ductwork adds depth. We measure the route as well as the unit position.
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.
Premises we work in around London
- Hotels and hospitality: quiet bedroom units, public-area cooling and heat recovery for hotels.
- Restaurants and cafés: dining rooms that stay comfortable next to a hot kitchen and a busy service.
- Warehouses and industrial: cooling for offices, mezzanines, control rooms and temperature-sensitive areas.
- Pubs and bars: cooling for busy bars, function rooms and cellars, sited with neighbours in mind.
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.

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.
Can one ducted unit serve several rooms?
It can, but every room then shares one thermostat. Rooms with different uses are better on separate units or zones.
Can ducted units bring in fresh air?
Some ducted units can accept a fresh-air connection; in other cases ventilation is provided separately.
