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.
March and surrounding areas
March is a smaller town in Cambridgeshire, with independent shops, offices, surgeries, pubs and local business units. Peterborough is about 23 km away.
That includes premises in PE15 and the surrounding districts. Nearby, we also cover Wisbech (about 14 km), Ely (about 21 km) and Peterborough (about 23 km). Buildings across Cambridgeshire 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 you get
- Fresh-air rate calculation for each space
- Filters, attenuators and fire dampers where required

From enquiry to handover in March
Assess
We work out how many people use each space and the fresh-air rate needed.
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. We keep work areas in March screened and tidy at the end of each day.
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.
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.
Noise
Fans and grilles are selected and attenuated to keep noise down.
Working hours
Most March businesses prefer noisy work outside trading hours. Early starts, evenings and weekends can be arranged and are priced up front.
