Commercial Duct Cleaning & Ventilation Hygiene

Commercial ventilation systems gather dust, debris, biofilm and — in kitchen extract systems — combustible grease deposits from the moment they are commissioned. Without a structured ventilation hygiene programme, internal cleanliness degrades steadily, indoor air quality falls, energy consumption rises as fans work harder against fouled coils and dampers, and the building moves out of compliance with the BESA TR19 standard for internal cleanliness of ventilation systems.

VentilationHygiene.uk delivers specialist duct cleaning, HVAC hygiene, AHU cleaning, grease extract cleaning and ventilation system inspection across the UK. Every project is scoped against TR19, evidenced with pre- and post-clean photography and, where required, quantitative deposit thickness testing and post-clean verification (PCV) reporting suitable for landlords, insurers and the fire risk assessor.

Our clients include facilities managers, FM companies, commercial landlords, property managers, healthcare estates, schools, offices, hospitality groups and industrial operators. The brief is always the same: bring ductwork back to a measurable, compliant standard of cleanliness and keep it there with a planned duct hygiene programme.

Whether you need a one-off TR19 duct clean ahead of an insurance inspection, an AHU hygiene survey on a large commercial estate, or a long-term commercial duct cleaning contract for a portfolio of buildings, the engagement starts the same way — an honest site survey, a clear scope of works and a written quotation you can put in front of the board.
