<h2>What Are Access Panels and Why Do They Matter?</h2>

<p>An access panel — sometimes called an inspection hatch or cleaning hatch — is an opening cut into the ductwork of a commercial kitchen extraction system to allow cleaning operatives to reach the interior of the duct. Without access panels positioned at the correct intervals, it is physically impossible to clean the entire ductwork to TR19 standard. Sections of duct that cannot be accessed will accumulate grease deposits over time, creating a fire risk that no amount of cleaning at accessible points can mitigate.</p>

<p>The BESA TR19 standard specifies that access panels must be installed at intervals that allow the entire ductwork to be cleaned and inspected. In practice, this means a panel every 1.5 to 3 metres on horizontal runs, at every change of direction, and at the fan inlet and outlet. The exact positioning depends on the duct dimensions and configuration — but the principle is clear: if a cleaning operative cannot reach a section of duct, that section is not compliant.</p>

<h2>The Access Panel Problem in Existing Kitchens</h2>

<p>Many commercial kitchens — particularly those in older buildings or those that have been refitted without specialist input — have extraction systems with inadequate or absent access panels. This is one of the most common deficiencies identified during TR19 site surveys. The problem typically arises in one of three ways:</p>

<h3>1. Original Installation Without Access Panels</h3>

<p>Some extraction systems were installed before the TR19 standard became widely adopted, or by contractors who were not familiar with the standard's access requirements. These systems may have no access panels at all, or panels positioned only at the fan — leaving long runs of ductwork inaccessible.</p>

<h3>2. Access Panels Covered During Refurbishment</h3>

<p>Kitchen refurbishments frequently involve boxing in or plastering over ductwork for aesthetic reasons. In the process, access panels that were originally installed may be covered over and rendered inaccessible. The ductwork is still there — and still accumulating grease — but the cleaning contractor can no longer reach it.</p>

<h3>3. Incorrect Panel Positioning</h3>

<p>Even where access panels are present, they may be positioned incorrectly — too far apart, on the wrong face of the duct, or at locations that do not allow the operative to reach the sections of duct where grease accumulates most rapidly. A panel on the top of a horizontal duct run, for example, may allow access to the top of the duct but not to the bottom, where grease pools and solidifies.</p>

<h2>TR19 Access Panel Specifications</h2>

<p>The TR19 standard sets out minimum specifications for access panels. Key requirements include:</p>

<ul>

<li><strong>Size:</strong> Access panels must be large enough to allow a cleaning operative to insert their arm and cleaning equipment into the duct. The minimum size for a rectangular duct is typically 200mm × 150mm, though larger panels are preferable for wider ducts.</li>

<li><strong>Positioning:</strong> Panels must be positioned at intervals that allow the entire duct run to be cleaned. On horizontal runs, this typically means a panel every 1.5 to 3 metres. Panels must also be positioned at every change of direction, at the fan inlet and outlet, and at any point where the duct changes dimension.</li>

<li><strong>Construction:</strong> Access panels must be constructed from the same material as the ductwork (typically galvanised steel or stainless steel) and must be capable of being resealed after cleaning to maintain the fire resistance of the duct.</li>

<li><strong>Sealing:</strong> Panels must be fitted with a gasket or sealant to prevent grease leakage and maintain the integrity of the duct. After cleaning, the panel must be resealed to the same standard.</li>

<li><strong>Labelling:</strong> Access panels should be clearly labelled to identify them as cleaning access points. This helps cleaning operatives locate all panels quickly and ensures that none are overlooked.</li>

</ul>

<h2>What Happens If Access Panels Are Missing?</h2>

<p>If your extraction system does not have adequate access panels, the consequences are significant:</p>

<h3>The System Cannot Be Cleaned to TR19 Standard</h3>

<p>A cleaning contractor cannot issue a TR19-compliant service report for sections of ductwork they cannot access. If they attempt to do so, they are producing fraudulent documentation. A reputable contractor will identify the access deficiencies in their report and recommend remedial action — but they cannot certify compliance for areas they have not cleaned.</p>

<h3>Your Insurance May Be Void</h3>

<p>If a fire starts in a section of ductwork that could not be cleaned because access panels were absent, your insurer will investigate whether the extraction system was maintained to the required standard. If the investigation reveals that sections of ductwork were inaccessible and therefore uncleaned, the insurer may decline the claim on the basis that the policyholder failed to maintain the system in a safe condition.</p>

<h3>You May Face Enforcement Action</h3>

<p>Environmental health officers and fire safety inspectors have the authority to require commercial kitchen operators to bring their extraction systems into compliance with relevant standards. A system without adequate access panels may be subject to an improvement notice or, in serious cases, a prohibition notice requiring the kitchen to cease operation until the deficiency is rectified.</p>

<h2>Installing Access Panels: What to Expect</h2>

<p>Access panel installation is a specialist task that should be carried out by a qualified extraction system engineer. The process involves cutting openings in the ductwork at the required positions, fitting the panel frames, installing the panels, and resealing the ductwork to maintain its fire resistance. The work typically takes one to three days depending on the size and complexity of the system.</p>

<p>BlueTick Extraction Hygiene offers access panel installation as part of our TR19 compliance service. We carry out a site survey to identify all access deficiencies, provide a detailed quotation for remedial work, and install panels to TR19 specification. Once the panels are installed, we carry out the initial TR19 clean and issue a compliant service report covering the entire system.</p>

<h2>Frequently Asked Questions</h2>

<h3>How do I know if my extraction system has adequate access panels?</h3>

<p>The most reliable way to determine whether your system has adequate access panels is to commission a TR19 site survey from a qualified extraction cleaning contractor. They will inspect the entire system and identify any access deficiencies. Alternatively, you can ask your current cleaning contractor to confirm in writing that they were able to access and clean the entire ductwork during their last visit.</p>

<h3>Who is responsible for installing access panels — the building owner or the kitchen operator?</h3>

<p>This depends on the terms of the lease or occupancy agreement. In most cases, structural modifications to the building (including ductwork modifications) are the responsibility of the building owner, but the kitchen operator may be required to obtain the owner's consent and fund the work. If you are a tenant, check your lease before commissioning access panel installation.</p>

<h3>How much does access panel installation cost?</h3>

<p>The cost depends on the number of panels required, the accessibility of the ductwork, and the complexity of the installation. As a rough guide, individual access panels typically cost £80–£200 each to supply and install, including resealing the ductwork. A kitchen requiring five or six new panels might expect to pay £500–£1,200 for the installation work.</p>

<h3>Can I install access panels myself?</h3>

<p>Access panel installation requires cutting into the ductwork and resealing it to maintain fire resistance. This work should be carried out by a qualified engineer who understands the TR19 standard and the fire resistance requirements for kitchen extraction ductwork. DIY installation is not recommended and may invalidate your insurance if the work is not carried out to the required standard.</p>

<h3>Do access panels need to be replaced after each clean?</h3>

<p>No. Access panels are permanent fixtures that are opened for cleaning and resealed afterwards. They do not need to be replaced after each clean, though the gaskets and sealants should be inspected and replaced if they show signs of wear or damage.</p>
