Septic Local editorial · 8 October 2026
Start with the system you know
Tell the business whether the property uses a septic tank, cesspit or sewage treatment plant. If you are unsure, say so. Existing paperwork, past invoices and an accessible plant label can be useful. Do not lift a cover to identify the system. Give the approximate capacity or plant model only if it is already known; guessing can lead to a poorly specified visit.
Explain why you are calling
Distinguish a planned empty from a new problem. You might need routine waste removal, a manufacturer-scheduled service, a survey for a house purchase or an assessment of a fault. Describe what you have noticed, when it began and whether other work has already been done. An emptying contractor and a plant-service engineer may provide different services, even when they work for the same business.
Describe access before the appointment
Provide your full postcode and practical information about the approach. Mention narrow gates, low branches, restricted parking, soft ground and the approximate distance from safe parking to the tank. Describe only what you can see safely. Let the contractor decide whether its equipment is suitable and whether a preliminary visit is needed. Ask who will arrange access if the system is on shared land.
Have existing records ready
A previous emptying invoice, service report or installation plan can help explain the system and the work already completed. Share only information needed for the job. If several properties share the system, establish who can authorise work and who will handle the bill before arranging a visit. Do not assume that a tenant, neighbour or managing agent has the authority to approve an installation change.
Agree the first step and its cost
Ask what the first appointment includes: waste removal, diagnosis, maintenance or a written report. Confirm whether there is a call-out fee, volume allowance, disposal charge, VAT or an extra cost for difficult access. Ask what happens if the job cannot proceed. Agree how extra work will be approved, and keep the written quotation and appointment details.
Use a short call brief
You can say: “The property is at [postcode]. We have [system type, or not sure]. We need [service or symptom]. The last visit was [date, if known]. Access involves [restrictions]. Can you confirm coverage, what the first visit includes and the total charge?” There is no need to send bank details, identity documents or unrelated personal information. A clear brief is more useful than an attempted diagnosis.
