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 it works in Southampton
Assess
We work out how many people use each space and the fresh-air rate needed. For sites in Southampton 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
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.
Heat recovery
Bringing in cold air in winter costs energy. Heat recovery units reclaim much of it.
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.
Types of premises we cover in Southampton
- Pubs and bars: cooling for busy bars, function rooms and cellars, sited with neighbours in mind.
- Gyms and leisure: high-capacity cooling and fresh air for gym floors, studios and changing rooms.

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.
