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 Essex works
Assess
We work out how many people use each space and the fresh-air rate needed. For sites in Essex 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.
What to think about in Essex
Fire
Ducts passing through fire-rated walls or floors need fire dampers.
Access and parking
Town-centre jobs in Essex 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.
Noise
Fans and grilles are selected and attenuated to keep noise down.
Shared buildings
In multi-let buildings, roof space, risers and plant areas are often controlled by a managing agent. We work to their permits and method-statement requirements.
Typical premises in Essex
- Offices: zoned cooling and heating for open-plan floors, meeting rooms and comms rooms.
- Salons and spas: comfortable salons and treatment rooms despite dryers, lamps and steam.
- 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.
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).
