Commercial Grease Traps & Grease Interceptors

A grease trap is a plumbing device that captures fats, oils and grease (FOG) from wastewater before it enters the sewer system, helping to protect commercial drainage systems from costly blockages and damage.

Most grease traps work using gravity separation, allowing grease to rise to the surface while heavier solids settle below, leaving cleaner wastewater to flow into the drainage system.

Choosing a grease trap with the correct flow rate ensures wastewater can pass through efficiently while allowing fats, oils and grease to separate effectively.

Choosing the Right Grease Trap

Different grease trap designs offer varying levels of grease retention, so selecting the correct size and type is essential for maintaining effective grease management and protecting your drainage system. Selecting the right grease trap involves more than choosing the correct tank size. Factors such as hydraulic capacity, expected flow rates and grease production all influence how effectively the system will perform. Choosing an EN 1825 compliant grease trap helps ensure the system meets recognised European standards for the separation of fats, oils and grease from wastewater.

Our range of commercial grease traps includes a variety of capacities, materials and installation options to suit different kitchen layouts and wastewater volumes.

Whether you need an above-ground or below-ground system, an automatic grease removal unit or a manual grease trap, we can help you choose the right product based on available space, expected flow rates and grease production. Every system is designed to deliver reliable performance and consistent grease retention, helping protect commercial drainage while supporting compliance in busy commercial kitchens.

Our systems are suitable for a wide range of food service establishments, from cafés and pubs to restaurants, hotels and large catering facilities. Selecting a unit with the appropriate flow rate and capacity helps maximise grease trap performance, reduce maintenance requirements and extend the lifespan of your drainage system.

Depending on the type of system, grease traps may use gravity separation, automatic grease removal or a combination of both to effectively remove FOG from wastewater.

7 Key Benefits of Commercial Grease Traps

1. Prevents Drain Blockages

The first key benefit of grease traps is that they capture fats, oils, and grease from wastewater before they enter the plumbing system, reducing the risk of clogs/expensive blockages & disruption to your commercial drainage system.

By using gravity separation & other technologies to remove grease before it reaches your drainage system, blockages can often be prevented before they become costly problems.

2. Protects Sewer Systems

By preventing FOG from entering commercial drainage and sewer systems, grease traps help reduce infrastructure damage and costly maintenance.

3. Environmental Protection

Grease traps remove FOG from wastewater, protecting aquatic ecosystems and complying with environmental regulations.

4. Regulatory Compliance

Many food service establishments are required to install and maintain grease management systems to help comply with UK drainage and wastewater regulations. Choosing an EN 1825 compliant grease trap provides confidence that your system has been designed in line with recognised standards for grease separation. Ensuring that your kitchen has one will help you avoid fines and closures due to non-compliance.

5. Cost Savings

Another key benefit of using a grease trap is cost savings. Preventing grease blockages and backups reduces emergency plumbing calls, pipe repairs, and downtime, saving your business money over time.

6. Reduces Odours

Properly maintained fat traps reduce any foul odours caused by decomposing food waste and grease.

7. Supports Grease Recycling

The final benefit is that they often support grease recycling. Collected grease can often be recycled, supporting sustainability efforts.
