How to Choose the Right Grease Trap for Your Commercial Kitchen

Running a commercial kitchen comes with strict hygiene, plumbing, and environmental responsibilities. One critical element in keeping everything running smoothly and legally is the grease trap.

Choosing the right grease trap isn’t just about compliance; it’s about efficiency, long-term savings, and odour control. In this guide, we’ll walk you through everything you need to know to make the best decision for your kitchen.

What Is a Grease Trap and Why Do You Need One?

A grease trap, also known as a grease interceptor, is a plumbing device that captures fats, oils, and grease (FOG) from wastewater before it enters the drainage system. Without one, FOG can cause blockages, odours, and compliance violations.

Key Benefits:

• Prevents blocked drains and plumbing issues
• Reduces foul kitchen odours
• Helps meet food hygiene and water authority regulations
• Minimises environmental pollution
• Reduces risk of costly fines or closures

Factors to Consider When Choosing a Grease Trap

Not all grease traps are made equal. The best one for your business depends on several variables:

1. Type of Kitchen and Volume of FOG

Start by assessing:

• Type of food you prepare (e.g., fried, grilled, oily)
• Number of meals served daily
• Size and type of kitchen appliances connected to wastewater

Tip: Higher FOG output requires a larger or automated system.

2. Type of Grease Trap System

There are three primary types:

Domestic Passive Grease Traps

• Ideal for small cafés, home kitchens, or light use
• Simple design, low maintenance

Commercial Passive Grease Traps – CE Range

• Suitable for medium to large commercial kitchens
• Stainless steel design with larger holding capacity
• Cost-effective and compliant with EN 1825 standards

Commercial Automatic Grease Traps

• Self-cleaning and programmable
• Includes heating, skimming, and timed drainage
• Best for busy commercial kitchens with high-volume FOG

3. Local Regulations and Compliance

Most UK and Ireland councils and water authorities require:

• Installation of CE-marked grease traps
• Regular cleaning and servicing records
• Proof of FOG management plan

Always check with your local environmental officer or water company to ensure you’re compliant.

4. Space and Location

Grease traps can be installed:

• Under-sink (internal) – Good for smaller systems with space under counters
• Externally (outdoor pits) – Ideal for large restaurants or facilities with heavy FOG
• In-ground or on-ground units – Depending on drainage and building layout

Work with a professional to determine the optimal installation point.

5. Ease of Maintenance

Even the best grease trap needs cleaning. When choosing:

• Look for units with easy-access lids or removable baffles
• Consider biological dosing to reduce FOG build-up and odour
• Choose reputable suppliers that offer maintenance contracts

Add-On Solutions to Boost Performance

Pairing your grease trap with accessories can enhance performance and lifespan.

• Grease Trap Odour Control (like FIX-60™): Neutralises foul smells at the source
• Biological Grease Trap Cleaners: Breaks down FOG and organic waste naturally
• Sink Strainers and Drain Covers: Prevents large solids from entering the system
