<h2>Why Contractor Selection Matters More Than You Think</h2>

<p>When a commercial kitchen fire occurs and the insurer investigates, the first question they ask is not whether the extraction system was cleaned — it is whether it was cleaned to the correct standard, by a qualified contractor, at the correct frequency, and whether the documentation proves it. A cleaning certificate from a contractor who does not understand TR19 is worth nothing in that situation. Worse, it may give you false confidence that you are compliant when you are not.</p>

<p>The TR19 extraction cleaning market in the UK is fragmented. There are large national contractors, regional specialists, and sole traders, all offering "TR19 cleaning." The quality of their work, their understanding of the standard, and the quality of their documentation varies enormously. This guide will help you identify the contractors who will genuinely protect your business — and avoid those who will not.</p>

<h2>The Five Criteria That Matter</h2>

<h3>1. Evidence of TR19 Training and Competence</h3>

<p>The BESA TR19 standard does not require contractors to hold a specific licence or certification to carry out extraction cleaning. However, reputable contractors will be able to demonstrate competence through BESA membership, completion of TR19 training courses, or membership of a relevant trade body. Ask any prospective contractor to provide evidence of their TR19 training. If they cannot, or if they are vague about what training their operatives have received, that is a significant warning sign.</p>

<p>BESA (Building Engineering Services Association) is the primary trade body for extraction cleaning contractors in the UK. BESA members are required to adhere to the TR19 standard and are subject to audit. Choosing a BESA member contractor provides a baseline level of assurance that the work will be carried out to the correct standard.</p>

<h3>2. Adequate Public Liability Insurance</h3>

<p>Any contractor working in your kitchen carries risk. If they damage your equipment, cause a fire, or injure a member of staff, you need to know that they have adequate insurance to cover the loss. The minimum acceptable level of public liability insurance for a TR19 cleaning contractor is £5 million. Ask to see their certificate of insurance before work commences, and check that it is current and covers the type of work being carried out.</p>

<p>Be cautious of contractors who are reluctant to provide their insurance certificate, or whose certificate shows a lower limit than £5 million. Some contractors carry only £1 million or £2 million of cover — adequate for minor incidents, but potentially insufficient for a significant loss.</p>

<h3>3. The Quality of Their Service Report</h3>

<p>This is the most important criterion of all. A TR19 service report is the document that proves your extraction system has been cleaned to the correct standard. It is the document your insurer will ask to see at renewal, and the document that will determine whether a claim is paid or declined if a fire occurs. A good TR19 service report should include:</p>

<ul>

<li>Photographic evidence of the system before and after cleaning</li>

<li>Deposit thickness measurements taken at multiple points in the ductwork</li>

<li>A description of the areas cleaned and the method used</li>

<li>Confirmation that the system has been cleaned to TR19 standard</li>

<li>The contractor's name, qualifications, and insurance details</li>

<li>The date of the clean and the recommended date of the next clean</li>

<li>Any deficiencies identified (missing access panels, damaged components, etc.)</li>

</ul>

<p>Ask to see a sample service report before engaging a contractor. If the report is a single page with a few photographs and a tick-box checklist, it is unlikely to satisfy a rigorous insurer. A proper TR19 service report is typically 10–20 pages long and provides comprehensive evidence of compliance.</p>

<h3>4. Understanding of Insurance Requirements</h3>

<p>The best TR19 contractors understand not just the cleaning standard, but the insurance context in which it operates. They know which insurers require TR19 compliance certificates at renewal, what cleaning frequencies different insurers expect, and how to produce documentation that satisfies underwriter requirements. This knowledge comes from experience working alongside insurance professionals — not from reading the TR19 standard in isolation.</p>

<p>BlueTick Extraction Hygiene was founded by a CII-qualified insurance professional who works alongside Focus Insurance Services, an FCA-regulated commercial insurance brokerage. This means our service reports are designed to satisfy insurer requirements — not just to demonstrate that a clean has taken place.</p>

<h3>5. Transparency About Access and Limitations</h3>

<p>A TR19-compliant clean requires access to the entire extraction system — canopy, ductwork, risers, fans, and any other components. If access panels are missing or incorrectly positioned, sections of the ductwork cannot be cleaned, and a TR19-compliant service report cannot be issued for those sections. A reputable contractor will identify access deficiencies before or during the clean and advise you on how to rectify them. A less reputable contractor may issue a service report that does not acknowledge the access limitations — leaving you with documentation that appears compliant but is not.</p>

<h2>Red Flags to Watch For</h2>

<p>The following are warning signs that a contractor may not deliver the standard of work you need:</p>

<ul>

<li><strong>Unusually low prices:</strong> TR19 cleaning is labour-intensive and time-consuming. A price that seems too good to be true usually means corners are being cut — either in the thoroughness of the clean or the quality of the documentation.</li>

<li><strong>Reluctance to provide a sample report:</strong> If a contractor cannot or will not show you a sample service report before you engage them, that is a significant warning sign.</li>

<li><strong>No mention of access panels:</strong> A contractor who does not ask about access panel provision before quoting has either not thought about it or does not intend to clean the full system.</li>

<li><strong>Vague about cleaning frequency:</strong> A contractor who quotes a single annual cleaning frequency for all kitchens without asking about your cooking hours does not understand the TR19 standard.</li>

<li><strong>No public liability certificate available:</strong> Any legitimate contractor should be able to provide their insurance certificate on request.</li>

</ul>

<h2>Questions to Ask Before Engaging a Contractor</h2>

<ol>

<li>Can you provide evidence of TR19 training for your operatives?</li>

<li>Are you a BESA member or affiliated with a relevant trade body?</li>

<li>Can I see a sample service report from a recent job?</li>

<li>What is your public liability insurance limit, and can I see the certificate?</li>

<li>How do you determine the appropriate cleaning frequency for my kitchen?</li>

<li>What happens if you identify missing access panels during the clean?</li>

<li>Will your service report satisfy my insurer's requirements at renewal?</li>

</ol>

<h2>Frequently Asked Questions</h2>

<h3>Do I need a BESA-registered contractor for TR19 cleaning?</h3>

<p>The TR19 standard does not legally require you to use a BESA-registered contractor. However, BESA membership provides assurance that the contractor adheres to the standard and is subject to audit. Many insurers prefer or require BESA-registered contractors.</p>

<h3>How much should TR19 cleaning cost?</h3>

<p>Pricing varies depending on the size and complexity of the extraction system, the cleaning frequency required, and the contractor's location. As a rough guide, a straightforward canopy and short duct run clean for a small commercial kitchen might cost £200–£400. A full system clean for a large restaurant or hotel kitchen with extensive ductwork could cost £800–£2,000 or more. Be cautious of prices significantly below these ranges.</p>

<h3>Can I use any cleaning company for TR19 cleaning, or does it need to be a specialist?</h3>

<p>TR19 extraction cleaning requires specialist equipment, training, and knowledge. A general commercial cleaning company is unlikely to have the equipment or expertise to carry out a TR19-compliant clean. Always use a specialist extraction cleaning contractor.</p>

<h3>How do I know if my current contractor is producing compliant documentation?</h3>

<p>Ask your insurer or insurance broker to review your current TR19 service report. They will be able to tell you whether it meets their requirements. Alternatively, contact a specialist TR19 contractor and ask them to review the report — most reputable contractors will do this as a free service.</p>

<h3>What should I do if my contractor cannot access part of the extraction system?</h3>

<p>If access panels are missing or incorrectly positioned, the contractor should identify this in their service report and advise you on how to rectify the situation. You should then arrange for access panels to be installed before the next clean. Do not accept a service report that claims full TR19 compliance if the contractor was unable to access part of the system.</p>
