Ductwork and Extraction System Cleaning

ProVent Kitchen Clean TR19-certified ductwork and extraction system cleaning service removes dangerous grease deposits from every component of your commercial kitchen ventilation system — including internal ductwork, extract ducts, risers, plenums, access panels, inline fans, and roof-mounted exhaust units. Every clean is carried out by BESA-trained engineers using specialist rotary brush systems, high-pressure steam, and industrial-grade degreasers to achieve full TR19 compliance.

Grease accumulation inside commercial kitchen ductwork is the single biggest cause of kitchen fires in the UK. Dirty extract ducts restrict airflow, drive up energy costs, create persistent odours, and put your insurance policy at serious risk. Environmental Health Officers (EHO) and fire inspectors actively check TR19 compliance records — without a valid certificate, you risk improvement notices, fines, or forced closure.

Our ductwork and extraction system cleaning covers restaurants, hotels, schools, hospitals, care homes, pub kitchens, dark kitchens, ghost kitchens, staff canteens, and any commercial catering premises across London and all of England.

TR19 Cleaning Frequency Guidelines (BESA):
Heavy use kitchens (12–16 hrs/day): every 3 months
