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.

From enquiry to handover in Lancashire
Assess
We work out how many people use each space and the fresh-air rate needed. For sites in Lancashire 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
Noise
Fans and grilles are selected and attenuated to keep noise down.
Leased premises
If your Lancashire 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.
Fire
Ducts passing through fire-rated walls or floors need fire dampers.
Access and parking
Town-centre jobs in Lancashire 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.
Types of premises we cover in Lancashire

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).
