FAQs
Commercial Duct Cleaning & TR19 Questions
Common questions from facilities managers and estates teams about TR19 ventilation hygiene, kitchen extract cleaning and marine HVAC works.
- What is TR19 duct cleaning?
- TR19 is the UK industry guidance on ventilation hygiene, with TR19 Grease covering kitchen extract systems. Deduct carries out inspection, cleaning and reporting in line with relevant TR19 requirements across commercial, healthcare, industrial and marine sites nationwide.
- How often should commercial ductwork be cleaned?
- TR19 guidance sets cleaning frequencies according to system use and risk. Kitchen extract systems in heavy-use commercial kitchens typically require cleaning every 3–6 months; general supply and extract ventilation in offices and healthcare is usually inspected annually.
- Do Deduct Ltd cover the whole UK?
- Yes. Deduct Ltd has provided nationwide commercial ventilation hygiene services across England, Scotland and Wales since 2015, with directly employed engineers and a national fleet.
