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.

Things to check in Colchester
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.
Fire
Ducts passing through fire-rated walls or floors need fire dampers.
Conservation areas
Historic streets and listed buildings in and around Colchester are more likely to need planning permission for outdoor units on visible elevations. We check with the local planning authority before work is booked.
Who we work with in Colchester
- Offices: zoned cooling and heating for open-plan floors, meeting rooms and comms rooms.
- Restaurants and cafés: dining rooms that stay comfortable next to a hot kitchen and a busy service.
- Salons and spas: comfortable salons and treatment rooms despite dryers, lamps and steam.
- Pubs and bars: cooling for busy bars, function rooms and cellars, sited with neighbours in mind.
Compliance in England: refrigerant work falls under GB F-gas rules, and buildings with more than 12 kW of air conditioning in total need a periodic energy inspection (often called TM44).
