Running a busy kitchen means juggling a thousand priorities at once – but there’s one area that often goes unnoticed until it becomes a serious problem: your kitchen extract system.
From fire risks to staff wellbeing, the cleanliness of your extract, ducting and canopy systems is more than just a box-ticking exercise. It’s a duty of care, a legal obligation, and a vital part of keeping your operation running smoothly.
What is Kitchen Extract Cleaning?
Your extract system is the set of components that remove airborne grease, smoke and heat from your kitchen. Over time, it becomes coated in grease, oil vapour and carbonised debris – the kind of stuff that isn’t just unpleasant, but highly flammable.
A proper clean involves every part of the system – from canopies and risers to fans and ductwork – ensuring it’s safe, hygienic and performing as it should.
Why It Matters
- Fire risk: Grease build-up is highly flammable and can spread flames rapidly through ducting.
- Staff wellbeing: Poor airflow affects working conditions and air quality.
- Compliance: Dirty systems risk breaching TR19, which can void insurance.
- Performance: Blocked ducts reduce airflow and affect kitchen efficiency.
What Is TR19 – and Why Does It Matter?
TR19 is the recognised industry standard for ventilation hygiene in commercial kitchens. Developed by BESA, it lays out what needs to be cleaned, how often, and to what standard.
At BCS, we follow TR19 to the letter. Every clean we carry out is done to meet or exceed these standards – so you can have confidence in your compliance and your cover.
