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.
Working in Derby
Derby is one of the main commercial centres in Derbyshire, with city-centre offices, retail streets, hospitality venues and business parks on its edges.
Postcode districts we cover in Derby include DE1. We also cover Belper, Ilkeston and Heanor, all within easy reach of Derby. Buildings across Derbyshire 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 we do
- Fresh-air rate calculation for each space
- Supply and extract fans, ductwork and grilles
- Filters, attenuators and fire dampers where required
- Controls such as timers or CO2 sensors
- Air-flow measurement and balancing

How we work in Derby
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 Derby screened and tidy at the end of each day.
Balance
Air flows are measured and balanced to the design.
Before you book in Derby
Heat recovery
Bringing in cold air in winter costs energy. Heat recovery units reclaim much of it.
Leased premises
If your Derby 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.
Conservation areas
Historic streets and listed buildings in and around Derby are more likely to need planning permission for outdoor units on visible elevations. We check with the local planning authority before work is booked.
Typical premises in Derby

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).
