How it works in Kent
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.

Balance
Air flows are measured and balanced to the design.
Things to check in Kent
Fire
Ducts passing through fire-rated walls or floors need fire dampers.
Leased premises
If your Kent premises are leased, the landlord's written consent is usually needed for external units, wall penetrations and roof access. We provide drawings and data sheets for the request.
Noise
Fans and grilles are selected and attenuated to keep noise down.
Access and parking
Town-centre jobs in Kent 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.
