When it comes to TR19 extraction cleaning, this creates a layered accountability structure that, if not managed carefully, can leave both the caterer and the client exposed.</p> <p>The BESA TR19 standard — formally titled "Guide to Good Practice for the Design, Installation, Inspection and Maintenance of Kitchen Ventilation Systems" — requires that extraction systems are cleaned at intervals determined by the volume and type of cooking. For a contract caterer operating in a corporate office canteen, a hospital kitchen, a school, and a factory canteen simultaneously, each site will have a different [cleaning frequency](/blog/how-often-should-commercial-kitchen-extraction-be-cleaned "How Often Should a Commercial Kitchen Extraction System Be Cleaned?") requirement, a different system configuration, and potentially a different insurer expecting different documentation.</p> <h2>What TR19 Requires of Contract Caterers</h2> <p>The TR19 standard does not distinguish between owner-operators and contract caterers. If your team is operating the kitchen, you are responsible for ensuring the extraction system is cleaned to the required standard and that a compliant service report is produced after each clean. The fact that you do not own the building is not a defence against an [insurance claim](/why-tr19-matters "Why TR19 Compliance Matters for Insurance") being declined or an enforcement notice being issued.</p> <p>For contract caterers, the key obligations are:</p> <ul> <li><strong>Cleaning frequency:</strong> Heavy-use kitchens (operating 12–16 hours per day) require quarterly cleaning. Moderate-use kitchens (6–12 hours per day) require six-monthly cleaning. Light-use kitchens (under 6 hours per day) require annual cleaning. These are minimum intervals — your client's insurer may require more frequent cleaning.</li> <li><strong>Documented service reports:</strong> Each clean must be accompanied by a TR19-compliant service report that includes photographic evidence, deposit thickness measurements, and a description of the work carried out. This report must be retained and made available to the client, their insurer, and any regulatory authority on request.</li> <li><strong>Access panel compliance:</strong> The extraction ductwork must have access panels installed at intervals that allow the entire system to be cleaned and inspected. If access panels are missing or incorrectly positioned, the system cannot be cleaned to TR19 standard and the service report cannot be issued.</li> <li><strong>Contractor qualifications:</strong> The cleaning contractor must be able to demonstrate competence. BESA membership, TR19 training certification, and adequate public liability insurance (minimum £5 million) are the standard benchmarks.</li> </ul> <h2>Building a Compliance Framework for Multiple Sites</h2> <p>The most effective approach for contract caterers is to treat [TR19 compliance](/services "TR19 Kitchen Extract Cleaning Services") as a scheduled maintenance programme rather than a reactive task. This means creating a compliance calendar at the start of each contract that maps out the required cleaning frequency for each site, assigns responsibility for booking and overseeing each clean, and establishes a document management system for storing service reports.</p> <p>A practical framework for a contract caterer managing ten or more sites would include the following elements:</p> <h3>1. Site Audit at Contract Commencement</h3> <p>Before taking on a new catering contract, commission a TR19 [site survey](/request-quote "Request a Free Site Survey") of the extraction system. This establishes the baseline condition of the system, identifies any access panel deficiencies, and determines the appropriate cleaning frequency. The survey report also provides a record of the system's condition at the point you took over the contract — important if a dispute arises later about pre-existing issues.</p> <h3>2. Cleaning Schedule Aligned to Cooking Hours</h3> <p>Map each site's cleaning schedule to its actual cooking hours, not a blanket annual programme. A corporate canteen operating five days a week for four hours per day is a light-use kitchen requiring annual cleaning. A hospital kitchen operating 18 hours per day, seven days a week, is a heavy-use kitchen requiring quarterly cleaning. Using a single cleaning frequency across all sites will either leave high-use kitchens under-cleaned (a compliance and insurance risk) or over-clean light-use kitchens (an unnecessary cost).</p> <h3>3. Centralised Document Management</h3> <p>All TR19 service reports, site survey reports, and access panel installation records should be stored in a centralised document management system accessible to your operations team, your clients, and your insurance broker. Cloud-based systems work well for this purpose. When a client's insurer requests evidence of TR19 compliance at renewal, you should be able to produce the relevant documents within minutes, not days.</p> <h3>4. Contractual Clarity with Clients</h3> <p>Your catering contract should clearly define who is responsible for commissioning TR19 cleaning — you as the caterer, or the client as the building owner. In practice, most contract caterers take responsibility for this as part of their service offering, but the contract should make this explicit. It should also specify the cleaning frequency, the standard to which cleaning will be carried out, and the documentation that will be provided.</p> <h2>Insurance Implications for Contract Caterers</h2> <p>Contract caterers typically carry their own public liability and employers' liability insurance, but the building owner's property insurance is also relevant. If a fire starts in an extraction system that has not been cleaned to TR19 standard, the building owner's insurer will investigate whether the cleaning obligation was met. If the contract caterer was responsible for TR19 compliance and failed to meet it, the insurer may seek to recover their losses from the caterer.</p> <p>This is not a theoretical risk. Commercial kitchen fires caused by grease accumulation in extraction systems are a well-documented cause of loss in the UK hospitality and catering sector. The Association of British Insurers and the Fire Protection Association have both published guidance linking inadequate extraction cleaning to fire risk. Insurers are increasingly requiring TR19 compliance certificates at renewal, and some are including TR19 cleaning obligations as a policy condition — meaning a failure to comply could invalidate cover entirely.</p> <p>Contract caterers should also be aware that their own public liability policy may contain conditions relating to kitchen hygiene and fire prevention. A claim arising from a kitchen fire in a site where TR19 cleaning was overdue could be declined on the basis that the caterer failed to take reasonable precautions to prevent loss.</p> <h2>Choosing a TR19 Contractor for Multi-Site Work</h2> <p>When selecting a TR19 cleaning contractor for multi-site work, the key criteria are consistency, documentation quality, and geographic coverage. A contractor who can service all of your sites to the same standard, using the same reporting format, and within a consistent timeframe is far more valuable than a collection of local contractors with varying quality levels.</p> <p>BlueTick Extraction Hygiene works with contract caterers across [Peterborough](/blog/tr19-kitchen-extract-cleaning-peterborough "TR19 Kitchen Extract Cleaning in Peterborough"), Cambridgeshire, Lincolnshire, and Northamptonshire, providing TR19-compliant cleaning services with standardised documentation that satisfies insurer requirements. [Our founder](/about "About BlueTick Extraction Hygiene")'s CII qualifications mean we understand exactly what insurers need to see in a compliance report — and we produce it as standard on every job.</p> <h2>[Frequently Asked Questions](/faq "TR19 Compliance FAQ")</h2> <h3>Who is responsible for TR19 cleaning — the contract caterer or the building owner?</h3> <p>This depends on the terms of the catering contract. In most cases, the contract caterer takes responsibility for TR19 cleaning as part of their service. The contract should make this explicit. If the contract is silent on the point, both parties may have exposure.</p> <h3>How often does a contract catering kitchen need to be cleaned to TR19 standard?</h3> <p>Cleaning frequency is determined by cooking hours. Heavy-use kitchens (12+ hours per day) require quarterly cleaning. Moderate-use kitchens (6–12 hours per day) require six-monthly cleaning. Light-use kitchens (under 6 hours per day) require annual cleaning. Your client's insurer may require more frequent cleaning.</p> <h3>What documentation does a TR19 clean produce?</h3> <p>A TR19-compliant service report includes photographic evidence of the system [before and after](/gallery "TR19 Cleaning Photo Gallery") cleaning, deposit thickness measurements, a description of the work carried out, and confirmation that the system has been cleaned to TR19 standard. The report should be signed by the cleaning contractor and retained by both the caterer and the client.</p> <h3>Can a contract caterer be held liable for a kitchen fire caused by grease in the extraction system?</h3> <p>Yes. If the contract caterer was responsible for TR19 cleaning and failed to meet the required standard, they may be liable for losses arising from a fire caused by grease accumulation. Their public liability insurer may also decline to cover the claim if TR19 compliance was a policy condition.</p> <h3>What should I look for when choosing a TR19 contractor for multi-site work?</h3> <p>Look for BESA membership or TR19 training certification, a minimum of £5 million public liability insurance, a standardised reporting format that satisfies insurer requirements, and geographic coverage across all of your sites. Experience with contract catering clients is a significant advantage.</p>
