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.
Gravesend and surrounding areas
Businesses in Gravesend range from independent shops and restaurants to offices, clinics and warehouses. Gillingham is about 14 km away.
That includes premises in DA12 and the surrounding districts. We also work in nearby Grays, Strood and South Ockendon. Buildings across Kent 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

Points to plan for in Gravesend
Building Regulations
New or altered ventilation in England must meet Approved Document F. We design to it and hand over the commissioning records.
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.
Heat recovery
Bringing in cold air in winter costs energy. Heat recovery units reclaim much of it.
Leased premises
If your Gravesend 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.
Types of premises we cover in Gravesend
- Salons and spas: comfortable salons and treatment rooms despite dryers, lamps and steam.

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).
