In any commercial kitchen, cleanliness is non-negotiable—not just for compliance but for the health and safety of staff and customers alike. At Cater Clean 24 Seven, we understand that one of the most critical components of maintaining kitchen hygiene is the ductwork. Regular kitchen extract cleaning of your system are vital, but without proper access, they can be near impossible. That’s where access hatches come in.
Why Are Access Hatches Essential for Kitchen Extract Cleaning?
Access hatches are designed to provide technicians with entry points into your kitchen’s ducting system. These hatches allow for thorough internal inspections, degreasing, and full kitchen extract cleaning, all of which are essential to prevent fire risks and ensure compliance.
Before you install access hatches, however, there are several key considerations you need to keep in mind.
Duct Size & Hatch Dimensions Importance for Kitchen Extract Cleaning
Hatches must be appropriately sized for the ductwork they serve. Oversized hatches may compromise duct integrity, while undersized hatches limit technician access.
-
- Standard guidelines:
- For ducting less than 500mm, install a hatch no smaller than 300mm x 200mm.
- For ducting over 500mm, hatches should be at least 450mm x 300mm.
- Custom solutions: In tight spaces, bespoke hatches may be necessary to provide safe and effective access.

Future-Proofing for Kitchen Extract Cleaning
Think long-term. Installing access hatches now will make future inspections and deep cleans faster, safer, and more cost-effective.
- Reduced downtime: Well-planned hatches reduce disruption during scheduled cleans.
- Lower maintenance costs: Easier access = less labour-intensive work.
Location, Location, Location
The placement of access hatches is crucial for enabling a complete clean of the ductwork. Poorly positioned hatches can result in hard-to-reach areas where grease and contaminants accumulate over time.
- Best Practice: Install hatches at regular intervals (typically every 3-4 meters) and near key components like bends, risers, and fans to allow full reach during cleans.
- Consider obstacles: Think about surrounding infrastructure, such as walls or equipment, which may limit access to certain ducting sections.
Sealing & Fire Safety
Improperly sealed hatches can compromise your duct system’s fire integrity and air-tightness.
- Gasket seals: Ensure hatches come with high-quality, heat-resistant gaskets to prevent air and grease leakage.
- Compliance: Install hatches that meet the fire-resistance rating of the ductwork system, maintaining protection in the event of a fire.
Regulatory Compliance
Access hatch installation must align with industry standards for fire safety compliance. Non-compliance can not only void insurance but also pose serious health and safety risks.
- Tip: Always engage qualified professionals who understand these regulations inside-out.
Material Compatibility
The access hatch material must be compatible with the ductwork to ensure durability and maintain fire resistance.
- Stainless steel: Often recommended for its corrosion resistance and strength, especially in high-temperature or high-grease environments.
- Galvanised steel: A common choice for general commercial applications but may not be suitable for all environments.
Always ensure that any hatch installed complies with relevant industry standards.
