Commercial kitchen extraction: a buyer's guide
Kitchen extraction guide
A commercial kitchen extraction system needs a canopy that overhangs the cooking, grease filters, a correctly sized fan and ductwork, make-up air, and a gas interlock where gas appliances are used. Expect £5,950 to £11,950 excluding VAT for a café or takeaway system.
How big should the canopy be?
Large enough to overhang the cooking equipment on the open sides, so rising heat and grease are captured rather than spilling out.
What is a gas interlock?
A control that stops the gas supply to cooking appliances unless the ventilation is running, normally required for commercial gas kitchens following BS 6173.
Do I need planning permission?
New external flues or discharges often need planning permission, and conditions commonly cover odour control and noise.
What is make-up air?
Fresh air brought back in to replace extracted air, so the kitchen does not go into strong negative pressure.
How often must it be cleaned?
To TR19 Grease: every 3, 6 or 12 months depending on usage.
