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.
Covering Weymouth and nearby
Weymouth has a compact centre of shops, cafés and offices, with business units on its outskirts. Poole is about 35 km away.
We work across Weymouth's postcode districts, including DT3 and DT4. Nearby, we also cover Poole (about 35 km), Yeovil (about 38 km) and Bournemouth (about 43 km). Buildings across Dorset 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
- 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
- Commissioning records

How a job in Weymouth works
Assess
We work out how many people use each space and the fresh-air rate needed.

Install
Ductwork and fans are installed and connected to controls. In Weymouth we agree timings around your opening hours.
Balance
Air flows are measured and balanced to the design.
Points to plan for in Weymouth
Heat recovery
Bringing in cold air in winter costs energy. Heat recovery units reclaim much of it.
Leased premises
If your Weymouth 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.
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 Weymouth are more likely to need planning permission for outdoor units on visible elevations. We check with the local planning authority before work is booked.
Types of premises we cover in Weymouth
- Offices: zoned cooling and heating for open-plan floors, meeting rooms and comms rooms.
- Gyms and leisure: high-capacity cooling and fresh air for gym floors, studios and changing rooms.
- Pubs and bars: cooling for busy bars, function rooms and cellars, sited with neighbours in mind.
- 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).
