Make one system file
- Keep the manufacturer manual, model, installation information and site plan if available.
- Keep authorisation, registration, consent or permit documents and any conditions.
- Store service reports, emptying dates, invoices and the faults or repairs reported.
- Note the company’s public contact details and the registration used for waste collection.
Use a competent service company
England’s ground-discharge guidance says anyone carrying out maintenance must be competent. Ask the firm to explain its experience with your specific system rather than relying on a broad advertising claim.
- Ask what routine tasks the manufacturer specifies.
- Ask which tasks are for a trained service engineer. This guide gives no electrical, tank-entry or lid-removal instructions.
Separate routine care from a fault
- If a service report identifies a defect, ask for a clear explanation of the finding and proposed remedy.
- Request a separate repair scope and price where work is outside the planned service.
- Record changes to equipment or discharge arrangements and check the nation-specific permission implications.
Before a change of occupier
- Make the records easy to hand over.
- Ask who is responsible if a system serves more than one property.
- Give a buyer or new occupier the provider and regulator links needed to check unclear points.
This guide does not decide whether a particular installation meets every condition. Check unclear rules with your nation's regulator, and service, design or price questions with the firm.
