Commercial Kitchen Ventilation
Professional kitchen ventilation systems across Essex & London
Effective commercial kitchen ventilation is essential for safety, comfort, and performance. At JLG Kitchens & Vent, we design, install, and maintain commercial kitchen ventilation systems in Essex, London, and areas within the M25, providing reliable extraction, fresh air supply, and full regulatory compliance. With more than 24 years of experience supporting the commercial catering industry, we help restaurants, takeaways, schools, hotels and food production businesses create cleaner, cooler and more efficient kitchens.
Fresh air, clear airflow, happier kitchens
Our commercial kitchen ventilation service covers everything from design to full installation and commissioning. We ensure every system meets health and safety legislation, and complies with key industry standards including BS6173, DW/172, DW/144, and TR/19. For added protection, we install gas interlock systems so gas automatically shuts off if the ventilation system fails — helping you stay compliant and keeping staff safe.
​
We design systems using accurate calculations for extraction airflow, provide mechanical supply (fresh air) systems, and complete full air balancing to ensure your kitchen has the right pressure and airflow. This prevents heat build-up, reduces odours and grease, and creates a comfortable working environment for chefs and catering staff.
Airflow solutions built for busy kitchens
​
A properly designed commercial kitchen ventilation system plays a critical role in maintaining a safe and productive working environment. By removing heat, smoke, grease-laden air, and odours at source, effective ventilation helps protect staff, equipment, and the building itself.
Our approach focuses on delivering ventilation systems that perform reliably under real service conditions while supporting long-term efficiency and compliance.
Commercial Kitchen Ventilation Designed Around Your Operation
​
No two kitchens operate in the same way. We design ventilation systems based on your cooking methods, equipment, layout, and service demands to ensure airflow is balanced and effective throughout the space.
Our ventilation design process considers:
​
-
Cooking equipment heat and grease output
-
Kitchen layout and ceiling heights
-
Extraction canopy positioning
-
Make-up air and fresh air supply
-
Noise control and energy efficiency
-
Future expansion or equipment changes
​
This tailored approach helps deliver consistent performance while improving comfort for kitchen staff.
Extraction & Airflow That Supports Compliance
​
Commercial kitchen ventilation systems must support current UK standards and best-practice guidelines. Our systems are designed and installed with careful consideration for hygiene, fire safety, and operational requirements.
We provide:
​
-
Grease extraction systems designed for commercial use
-
Appropriate ductwork routing and access for cleaning
-
Consideration for fire suppression and safety systems
-
Balanced airflow to prevent negative pressure issues
​
By addressing compliance at the design and installation stage, we help reduce issues during inspections and avoid costly remedial work later.

Frequently Asked Questions
Commercial Kitchen Ventilation Installation
What is commercial kitchen ventilation?
Commercial kitchen ventilation is a system designed to remove heat, smoke, grease, steam, and cooking odours from a professional kitchen. It helps maintain safe air quality, protects equipment, improves working conditions, and ensures compliance with UK regulations.
Why is proper ventilation essential in a commercial kitchen?
Proper ventilation protects staff health, reduces fire risk, and prevents grease build-up on surfaces and ductwork. Without adequate ventilation, kitchens can fail inspections, suffer equipment breakdowns, and create unsafe or uncomfortable working environments.
What regulations apply to commercial kitchen ventilation in the UK?
Commercial kitchen ventilation must comply with recognised industry standards, including DW/172 and DW/144 for ventilation design, TR/19 for ductwork cleanliness and fire safety, and BS6173 where gas appliances are used. Compliance is essential for legal operation and insurance validity.
Do commercial kitchens with gas appliances need ventilation interlock systems?
Yes. Where gas appliances are present, a ventilation interlock system is typically required under BS6173. The interlock ensures gas supply cannot operate unless the ventilation system is running correctly, helping to prevent dangerous build-ups of heat or combustion gases.
What is a ventilation interlock system and do I need one?
A ventilation interlock system links the kitchen’s gas supply to the extraction system. If the ventilation fails, the gas supply is automatically shut off. Most commercial kitchens using gas appliances are legally required to have one to meet safety regulations.
What are COâ‚‚ monitors and why are they used in commercial kitchens?
COâ‚‚ monitors measure carbon dioxide levels in a kitchen environment. Elevated COâ‚‚ levels can indicate poor ventilation or incomplete combustion from gas appliances. These monitors help identify air quality issues early and support safe working conditions.
What ventilation is required for a basement commercial kitchen?
Basement kitchens require carefully designed ventilation due to limited natural airflow. Systems must provide sufficient extraction and fresh air supply while meeting DW/172, DW/144, and TR/19 guidance. Poorly designed basement ventilation can lead to compliance failures and operational issues.
How do I know what size ventilation system my kitchen needs?
Ventilation requirements depend on kitchen size, ceiling height, equipment type, and cooking load. A site survey allows airflow calculations, canopy sizing, and ductwork routes to be accurately assessed to ensure compliance and performance.
How do I start a commercial kitchen ventilation project?
The first step is a site survey. This allows existing conditions, equipment, access routes, and compliance requirements to be reviewed. From there, a suitable ventilation design and installation plan can be developed.
Do you offer site surveys and quotations for kitchen ventilation?
Yes. A free site survey and quotation is provided. This allows ventilation requirements, measurements, and compliance considerations to be assessed before any work begins.
What measurements are needed for commercial kitchen ventilation?
Key measurements include kitchen dimensions, ceiling heights, cooking equipment layout, duct routes, and external discharge locations. These are typically captured during the site survey to ensure accurate system design.
How much does commercial kitchen ventilation cost?
Costs vary depending on kitchen size, equipment heat output, ductwork complexity, and access constraints. While budget is important, investing in compliant ventilation reduces long-term risks, maintenance costs, and potential enforcement issues.
Do you work with kitchen designers, engineers, and installers?
Yes. Ventilation systems are coordinated with designers, engineers, and installers to ensure layouts, airflow requirements, and interlock systems integrate correctly with the overall kitchen design.
How often does commercial kitchen ventilation need cleaning?
TR/19 recommends regular inspection and cleaning based on kitchen usage. High-use kitchens may require ductwork cleaning every 3–6 months, while lower-use environments may require annual cleaning to remain compliant.
What health and safety standards do you follow during ventilation installation?
All installations follow strict health & safety compliant practices, including safe access methods, working at height controls, and risk assessments. PASMA and IPAF principles are applied where required.
What areas do you cover for commercial kitchen ventilation?
Commercial kitchen ventilation services are available across London, Essex, and inside and around the M25, supporting both standalone businesses and large-scale catering operations.
Why choose a specialist in commercial kitchen ventilation?
Specialist ventilation contractors understand airflow calculations, fire risk, grease management, and regulatory compliance. This ensures systems are designed and installed to perform reliably, pass inspections, and support long-term kitchen operations.
