Commercial ventilation, Kent
Ductwork installation in Kent
Spiral and rectangular galvanised ductwork, hung, insulated and sealed, across Kent.
- From £50 + VAT per metre
- Free survey
Ductwork carries air between the fan or unit and the rooms it serves, and how it is sized, hung and sealed decides how well the whole system performs. We supply and install spiral and rectangular galvanised ductwork, fittings, dampers, insulation and access panels.
Across Kent the job is priced the same way wherever you are: what is fitted, how long it takes and how far we travel. Towns we cover include Ashford, Canterbury, Maidstone, Gillingham and Chatham.

How we do it
Undersized or leaky ductwork forces fans to work harder and makes systems noisy. We work to recognised sheet-metal ductwork specifications, seal joints, fit access panels for cleaning and insulate ducts that run through cold spaces or carry cold air. We install for our own ventilation systems and for other contractors, from short runs in a shop to full warehouse and office distribution.
Insulation and fire dampers
Thermal insulation and dampers where ducts pass through compartments, as designed.
Access panels
Fitted for future cleaning and inspection.
Spiral ductwork
Round galvanised ductwork for supply and extract runs.

Questions about ductwork installation in Kent
Is the survey free in Kent?
For new installations on the UK mainland, yes. The survey is free and the quote that follows is fixed and in writing. Servicing, testing and repair visits are charged, and we confirm the cost before booking.
Spiral or rectangular duct?
Spiral duct is quicker to install and leaks less; rectangular duct fits shallow ceiling voids and larger airflows.
Do ducts need insulation?
Ducts carrying cold or warm air through unheated spaces usually need insulation to prevent heat loss and condensation.
Which rules apply to ventilation in Kent?
In England, ventilation in new and altered homes is covered by Approved Document F of the Building Regulations. Landlords also have duties under the Housing Health and Safety Rating System, and workplaces must be ventilated under the Workplace (Health, Safety and Welfare) Regulations 1992.
