Commercial Grease Trap Cleaning
Grease traps and interceptors prevent fats, oils, and grease (FOG) from entering the drainage system. Regular professional cleaning is a legal requirement under the Water Industry Act 1991 and a condition of most commercial kitchen insurance policies.
Protecting Your Drainage System from FOG Contamination
A grease trap (also called a grease interceptor or grease separator) is a plumbing device installed in commercial kitchen drainage systems to intercept fats, oils, and grease (FOG) before they enter the main sewer network.
Without regular cleaning, grease traps become saturated and cease to function, allowing FOG to enter the drainage system. This causes sewer blockages, environmental pollution, and can result in enforcement action from your local water authority.
Under the Water Industry Act 1991, businesses are legally responsible for preventing FOG from entering the public sewer. Failure to maintain a functioning grease trap can result in fines and prosecution.
Legal Requirement
Under the Water Industry Act 1991 and the Environmental Protection Act 1990, commercial kitchen operators are legally required to prevent grease from entering the public sewer. Thames Water, Anglian Water, and other water authorities enforce this requirement and can prosecute operators whose discharges block the sewer.
How Often Should a Grease Trap Be Cleaned?
Frequency depends on kitchen volume, menu type, and trap capacity. We assess your system and recommend the correct schedule at your free site survey.
How We Clean Your Grease Trap

All accumulated grease, solids, and wastewater are pumped out using specialist vacuum equipment. The trap is then thoroughly cleaned.
Inspection & Report
We inspect the trap for damage, check baffles and inlet/outlet pipes, and provide a written service report.
