Prepare the same scope for every bid. Compare methods, exclusions and handover evidence before price.
Inventory the equipment
Record the type and capacity of each trap or interceptor, location and available service history. Identify access covers and constraints without opening unsafe equipment. Explain kitchen hours and any delivery restrictions.
Define what is included
Ask whether the quote covers pumping, cleaning internal components, inspection and documented waste handling. Do not treat used cooking oil collection as automatically equivalent to grease trap service.
Agree the schedule
The appropriate programme depends on the equipment and applicable local requirements. Ask the provider to explain the proposed frequency and how findings will be recorded. Confirm the responsible utility rather than copying another city’s interval.
Compare the complete cost
Separate access, travel, after-hours work, blockage response and extra volume. Ask what documentation is supplied and who handles a missed visit or an incomplete service. Confirm area coverage directly with the operating company.
What to verify
- Trap or interceptor inventory and size
- Access and operating restrictions
- Full pump-out versus limited service
- Waste transport and service records
- Local utility requirements to confirm
- Frequency, extras and re-service terms
