Commercial Grease Trap

At Commercial Grease Trap, we deliver tailored grease management systems designed to control fats, oils, and grease (FOG) at source within commercial kitchens and food preparation environments. Our installation services focus on long-term performance, regulatory compliance, and operational efficiency, ensuring your drainage infrastructure remains protected and fully functional.

Commercial Grease Trap enables businesses to manage wastewater effectively by intercepting grease before it enters pipework, reducing the risk of system failure and supporting clean, compliant operations.

Why Choose Commercial Grease Trap?

Commercial Grease Trap provides a technically accurate and regulation-led approach to grease management. Commercial Grease Trap ensures systems are designed and installed in accordance with BS EN 1825 and local water authority requirements, which govern the separation and disposal of grease in commercial environments.

From a compliance standpoint, correct installation demonstrates that a business has taken appropriate steps to prevent FOG discharge into public sewers. This is critical under the Water Industry Act 1991, where failure to manage grease can lead to enforcement action or fines.

From an operational perspective, Commercial Grease Trap improves drainage reliability by preventing internal pipe blockages, reducing maintenance issues, and maintaining consistent wastewater flow. Systems are positioned and configured to optimise separation efficiency, ensuring maximum performance over time.

Safety is also improved through controlled waste handling, reduced risk of overflow, and proper system access for cleaning and servicing. Installation includes provision for safe maintenance access and airflow where required, ensuring the system can be managed without disruption or hazard.

By focusing on correct sizing, placement, and integration, Commercial Grease Trap delivers a robust and compliant solution that supports both day-to-day operations and long-term infrastructure protection.

How much does a Commercial Grease Trap Cost?

The cost of a commercial grease trap ranges from £1,000 to £15,000+.

The cost of Commercial Grease Trap installations depends on system specification, installation method, and site complexity.

Lower-cost installations generally involve compact internal units for smaller kitchens, while higher-cost projects include external or in-ground separators designed for high-volume operations.

Key cost factors include system capacity, flow rate requirements, location of installation, drainage modifications, and any groundwork or structural adjustments required.

Commercial Grease Trap provides long-term financial benefit by reducing emergency drainage repairs, avoiding regulatory penalties, and improving system longevity.

What does Commercial Grease Trap Include?

Commercial Grease Trap delivers a complete and technically detailed service:

• Flow rate assessment and system sizing – Calculation of wastewater output to ensure the grease trap meets operational demand and complies with BS EN 1825 requirements
• System selection and specification – Identification of the most suitable solution, including passive grease traps or automatic recovery units
• Internal and external installation options – Installation within plant rooms, kitchens, or externally with below-ground systems depending on site layout
• Drainage system integration – Connection into existing pipework with correct gradients, flow direction, and access points
• Groundworks and excavation – Preparation and installation for in-ground systems including structural support and reinstatement
• Ventilation and odour control considerations – Ensuring airflow and system design minimise odour build-up and maintain hygiene standards
• Commissioning and performance checks – Verification that the system operates correctly under expected load conditions
• Handover documentation – Detailed records including system specifications, maintenance guidance, and compliance information

Each installation is engineered to match the specific demands of the kitchen environment.

What is The Commercial Grease Trap Process?

The process begins with a technical survey of the site, including an evaluation of kitchen operations, equipment usage, and wastewater discharge patterns. Commercial Grease Trap determines the correct capacity and configuration required for compliance and performance.

A detailed installation plan is then developed, outlining system location, pipe routing, and any structural or groundwork requirements. Installation is carried out by experienced engineers, ensuring all connections, gradients, and components meet required standards.

Following installation, the system is commissioned and tested to confirm that grease separation is functioning effectively. Final documentation is issued to confirm compliance and provide a reference for ongoing maintenance.

Our structured approach ensures accuracy at every stage, from design through to operational readiness.

What Types of Businesses Require Commercial Grease Trap?

Commercial Grease Trap is essential for any operation producing grease-contaminated wastewater:

• High-volume restaurants – Continuous cooking processes generating significant grease output
• Hotel kitchens – Multi-service operations with large-scale food preparation
• Food manufacturing facilities – Industrial processing environments requiring high-capacity systems
• Quick service and takeaway outlets – Frequent use of fryers and oil-based cooking methods
• Institutional kitchens – Schools, hospitals, and catering facilities with regulated compliance requirements
• Shared commercial kitchens – Multi-user environments requiring reliable and scalable grease management

Each installation is adapted to the operational scale and compliance obligations of the business.

How Long does it Take to Install a Commercial Grease Trap?

Installation time typically ranges from one to five working days depending on system size, access conditions, and whether groundwork is required.

Internal installations are generally completed more quickly, while external or in-ground systems may require additional time for excavation, curing, and reinstatement.

Commercial Grease Trap ensures efficient scheduling to minimise disruption to kitchen operations.

How does Commercial Grease Trap Ensure Compliance and Safety?

Commercial Grease Trap ensures compliance by following recognised standards for system sizing, placement, and performance. Correct installation prevents untreated grease from entering the sewer network, supporting environmental protection and regulatory adherence.

From a safety perspective, properly installed systems reduce the risk of blocked drains, wastewater overflow, and hygiene issues within the kitchen. Access points are designed for safe maintenance, and system layouts minimise exposure to waste materials.

Documentation provided at completion supports inspections, audits, and ongoing compliance, ensuring that the system remains aligned with regulatory expectations throughout its lifecycle.

When Should You Work with Commercial Grease Trap?
