What is a Grease Trap and Why is It Important?
Understanding Grease Traps
A grease trap is a container that intercepts wastewater before it enters your drainage system. It captures FOG and solids while allowing cleaner water to flow out, protecting pipes from blockages and preventing FOG discharge into the sewer.
How Grease Traps Work
As wastewater enters the trap, fats and oils float to the top, while heavier solids sink to the bottom. A baffle system slows the flow and separates materials effectively. Regular emptying and maintenance are key to ensuring it continues working efficiently.

Grease Trap Cleaning & Maintenance
Routine Cleaning & Emptying
Regular grease trap cleaning is essential to prevent overflows, bad odours, and system failures. We follow the 25% FOG rule, cleaning the trap when grease reaches a quarter of its volume.

All FOG waste is collected and disposed of using licensed waste carriers. We issue waste transfer notes and maintain full compliance with duty-of-care requirements under UK environmental law.
Enzyme Dosing System Supply & Maintenance
For high-output kitchens, we supply, install, and service enzyme dosing units. These systems release natural enzymes into the pipework, helping break down FOG between cleanings.

Frequently Asked Questions
What is a grease trap and what does it do?
A grease trap captures fats, oils, grease, and solids from wastewater before it enters the main drainage system, preventing blockages and contamination.
How often should a grease trap be cleaned?
Typically every 2–4 weeks, or when grease reaches 25% of the trap’s depth. High-use kitchens may need more frequent cleaning.
Do I need a grease trap in my commercial kitchen?
Yes, most UK water authorities require grease management systems in food businesses under Building Regulations and trade effluent consent rules.
What size grease trap do I need?
The correct size depends on your kitchen’s wastewater output and grease load. We carry out site assessments to specify the right unit.
Is grease trap maintenance a legal requirement in the UK?
While not always a legal mandate, proper maintenance is essential to avoid fines, blockages, and environmental violations. Most water companies include it in consent agreements.
What are the signs that my grease trap needs cleaning?
Bad smells, slow drains, or backups in sinks are common signs. Regular maintenance prevents these issues.
