Commercial ventilation brings outdoor air into a building and removes stale air, using fans and ductwork to supply and extract air at the rates needed for the number of people and the activity.

How a job in London works
Assess
We work out how many people use each space and the fresh-air rate needed. For sites in London we confirm access and parking beforehand.
Design
Fan, duct and grille sizes are designed for air flow, noise and energy use.
Install
Ductwork and fans are installed and connected to controls.
Balance
Air flows are measured and balanced to the design.
Local points to consider
Fire
Ducts passing through fire-rated walls or floors need fire dampers.
Working hours
Most London businesses prefer noisy work outside trading hours. Early starts, evenings and weekends can be arranged and are priced up front.
Building Regulations
New or altered ventilation in England must meet Approved Document F. We design to it and hand over the commissioning records.
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.
Who we work with in London
- Offices: zoned cooling and heating for open-plan floors, meeting rooms and comms 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.
- 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.
