Interceptor Emptying & Maintenance
Petrol interceptors & grease traps — licensed, compliant, reliable
Professional interceptor emptying for fuel forecourts, car parks, commercial kitchens and food service businesses across Yorkshire. Licensed waste carriers with 30+ years of commercial tanker experience.
Commercial drainage compliance
What is an interceptor?
Interceptors protect the drainage network from harmful substances — and keeping them maintained is a legal requirement.
Interceptors are devices built into drainage systems at commercial sites. They trap harmful substances — waste oils and fuel at petrol forecourts, or fats, oils and grease at commercial kitchens — before those substances can reach the main drainage network or local watercourses.
As the trapped material builds up, the interceptor must be emptied to keep working. Neglected interceptors overflow, causing environmental contamination, drain blockages, and potential enforcement action from the Environment Agency or local authority.
We serve businesses across Yorkshire, including Wakefield, Huddersfield, Dewsbury, Barnsley, Pontefract, Bradford, Brighouse, Leeds and Halifax.
We are fully licensed waste carriers — all interceptor waste is handled and disposed of compliantly, with waste transfer documentation provided after every service.

Petrol Interceptor Emptying
Fuel forecourts, car parks & vehicle maintenance
Petrol interceptors are designed to stop waste oils and spilt fuel from reaching the main drainage network. Without regular emptying, trapped oils and silt build up until the system overflows — leading to environmental contamination and potential fines.
- Petrol stations and fuel forecourts
- Car parks and multi-storey car parks
- Vehicle maintenance workshops
- Fleet depots and haulage sites
Grease Trap Emptying & Cleaning
Commercial kitchens & food service businesses
Grease traps prevent fats, oils and grease from entering the drainage system where they solidify and cause blockages. Commercial kitchens are legally required to maintain working grease management systems — regular emptying keeps you compliant and your kitchen running.
- Restaurants and cafes
- Hotel and catering kitchens
- School and hospital kitchens
- Food production and processing sites
Why maintenance matters
The consequences of a neglected interceptor
Regular emptying is not optional — it is a legal requirement with real financial and environmental consequences.
Overflow and environmental risk
A full interceptor will allow oils, grease or fuel to bypass the system and enter watercourses — triggering Environment Agency enforcement action.
Legal and regulatory obligation
The Water Industry Act, Pollution Prevention Guidelines, and local authority grease management plans make regular emptying a legal requirement, not optional maintenance.
Operational and commercial cost
A blocked interceptor can shut down a kitchen or forecourt. Emergency callouts and remediation work cost significantly more than scheduled maintenance.
