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 Hertford and nearby
Hertford has a compact centre of shops, cafés and offices, with business units on its outskirts. Luton is about 25 km away.
That includes premises in SG13 and the surrounding districts. We also work in nearby Hoddesdon, Welwyn Garden City and Hatfield. Buildings across Hertfordshire 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 the job covers
- Fresh-air rate calculation for each space
- Filters, attenuators and fire dampers where required
- Controls such as timers or CO2 sensors

- Commissioning records

From enquiry to handover in Hertford
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 Hertford screened and tidy at the end of each day.
Balance
Air flows are measured and balanced to the design.
What to think about in Hertford
Fire
Ducts passing through fire-rated walls or floors need fire dampers.
Access and parking
Town-centre jobs in Hertford 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.
Heat recovery
Bringing in cold air in winter costs energy. Heat recovery units reclaim much of it.
Roof and height work
Flat roofs, high walls and atriums need the right access equipment and edge protection. We plan towers, MEWPs or scaffold before the job, not on the day.
Typical premises in Hertford
- Restaurants and cafés: dining rooms that stay comfortable next to a hot kitchen and a busy service.
- Schools and education: classroom cooling, ventilation and IT room cooling, installed in the holidays.
- Pubs and bars: cooling for busy bars, function rooms and cellars, sited with neighbours in mind.
- Healthcare and dental: clean, quiet cooling for surgeries, clinics, dental practices and care settings.
In England, systems holding 5 tonnes CO2 equivalent of refrigerant or more fall under GB F-gas rules, with regular leak checks and records; buildings with more than 12 kW of air conditioning in total also need a periodic energy inspection.
