TR19 Compliant Ventilation & Kitchen Extract Cleaning — Scotland-Wide
TR19 Ventilation Hygiene & Your Legal Obligations
As the Responsible Person or Duty Holder for your premises, you have a legal obligation to ensure your ventilation and extract systems are maintained to a safe and hygienic standard. Failure to do so is not just a compliance issue — it is a criminal liability.
Deep Clean Scotland has extensive experience delivering TR19-compliant ventilation hygiene services across Scotland — including full system tracing to ensure every section of ductwork is accounted for, inspected, and documented. As members of the Vent Hygiene Register, our work is carried out to a verified industry standard you can rely on.
Who Is the Responsible Person?
Under the Regulatory Reform (Fire Safety) Order 2005 and the Fire (Scotland) Act 2005, the Responsible Person is the employer, owner, or any person who has control of the premises. In a commercial kitchen or managed building, this is typically the business owner, head chef, facilities manager, or building manager.
The Responsible Person must carry out — or arrange — a suitable and sufficient fire risk assessment, and implement and maintain appropriate fire precautions. This explicitly includes the maintenance of extract ventilation systems, ductwork, and canopies to prevent the accumulation of grease and other combustible deposits.
The TR19 standard, published by the Building Technicianing Services Association (BESA), provides the recognised benchmark for ventilation hygiene compliance. Holding a valid TR19 certificate demonstrates that your legal duties have been discharged — and provides critical evidence in the event of an insurance claim or enforcement investigation.
Our technicians carry out full system tracing as part of every survey — mapping the complete ductwork layout to ensure no section is overlooked, undocumented, or left unchecked. As members of the Vent Hygiene Register, our services are independently verified against industry standards, giving you and your insurer confidence in the work carried out.

Relevant Legislation & Regulations
Ventilation hygiene obligations arise from multiple pieces of legislation. The Responsible Person must be aware of all of them.
Places a legal duty on the Responsible Person to take general fire precautions and ensure the premises are safe. Failure to maintain extract ventilation systems in a clean condition is a breach of this Order and can result in enforcement notices, prohibition orders, unlimited fines, and imprisonment.
The Scottish equivalent of the RRO. Requires the Duty Holder to carry out and act upon a fire risk assessment. Contaminated ductwork and extract systems are a recognised fire hazard that must be controlled. Non-compliance can result in criminal prosecution.
Requires employers to provide and maintain a safe working environment. Poorly maintained ventilation systems that harbour bacteria, mould, and contaminants directly affect the health of employees and building occupants.
Regulation 6 specifically requires that enclosed workplaces are ventilated by a sufficient quantity of fresh or purified air. Systems must be maintained in an efficient state, in efficient working order, and in good repair.
Requires food business operators to keep all articles, fittings, and equipment that come into contact with food clean and, where necessary, disinfected. This extends to the ventilation systems above and around food preparation areas.
What We Can Include
Remedial Works
Inspection does not always result in a clean — but it may identify deficiencies that must be addressed before a system can be certified as compliant. We carry out a range of remedial works in line with DW144, TR19, and associated regulations.
Where ductwork lacks adequate access for inspection or cleaning, we install access doors in line with DW144 (HVCA/BESA specification for sheet metal ductwork) and TR19 requirements. Access doors must be positioned at intervals specified by the standard — typically no more than 1.5m from any change of direction, obstruction, or item of plant — to allow full inspection and cleaning of every section. Inadequate access is one of the most common reasons a system cannot be certified as compliant.
Damaged, leaking, or poorly sealed ductwork compromises both hygiene and fire containment. We carry out repairs and re-sealing to DW144 standards, ensuring ductwork integrity is restored and the system performs as designed. Leaking joints can allow contaminated air — or in the event of a fire, smoke and flame — to spread beyond the extract system.
Where existing grease traps or filters are inadequate for the cooking load or system classification, we can advise on and install appropriate replacements. Correctly specified filtration reduces grease accumulation rates, extends the interval between cleans, and supports compliance with TR19 cleaning frequency requirements.
Extract fans that are underperforming or operating outside design parameters reduce the effectiveness of the entire system. We carry out fan and motor servicing to restore correct airflow, which is essential for both hygiene and fire safety — a system that cannot move air at the design rate will accumulate deposits more rapidly.
TR19 and DW144 require that ductwork is labelled to indicate cleaning dates, access point locations, and system classification. We apply compliant labelling as part of every service visit, ensuring your system records are accurate and auditable.
