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 Marlow
In a town like Marlow, a single wall unit for a shop or a cassette for a surgery makes a real difference in summer. High Wycombe is about 7 km away.
That includes premises in SL7 and the surrounding districts. Neighbouring towns we cover include Maidenhead, High Wycombe and Slough. Buildings across Buckinghamshire range from converted period offices to modern units with deep ceiling voids, so we measure each site rather than relying on a standard package.
Included as standard
- Fresh-air rate calculation for each space
- Supply and extract fans, ductwork and grilles
- Controls such as timers or CO2 sensors
- Air-flow measurement and balancing
- Commissioning records

Before you book in Marlow
Building Regulations
New or altered ventilation in England must meet Approved Document F. We design to it and hand over the commissioning records.
Conservation areas
Historic streets and listed buildings in and around Marlow are more likely to need planning permission for outdoor units on visible elevations. We check with the local planning authority before work is booked.
Noise
Fans and grilles are selected and attenuated to keep noise down.
Access and parking
Town-centre jobs in Marlow 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.
