Drainage field assessment and installation

A drainage field needs a suitable site and design. Repeated emptying may not resolve an underlying drainage problem. Ask a specialist to assess the complete system.

Before you book

  • Where the existing system discharges, if known.
  • Previous surveys or ground assessments.
  • Scope of excavation, testing and garden reinstatement.

Agree the scope of work

Explain your system type, the property location and what you want the visit to achieve. Ask whether the first appointment is an assessment, an emptying visit or the work itself. Get a written description so you can compare like-for-like quotes.

What affects the price?

Travel, access, waste volume, specialist equipment and the time needed can change the quote. Confirm VAT, disposal, additional visits and any charge if the tanker or engineer cannot gain access. For repair or installation work, agree who authorises extra parts or excavation.

Use the quote comparison checklist.

Do not enter a tank, lift heavy covers or handle sewage to investigate a fault. Keep people and pets away from a suspected overflow or damaged cover and contact a specialist. This directory is not an emergency response service.

Common questions

Does this book an appointment?

No. Contact your chosen contractor to agree a visit. The optional help-request form saves an enquiry for owner review, not a confirmed appointment.

Can I assume the same rules apply across the UK?

No. Regulatory requirements differ between England, Wales, Scotland and Northern Ireland. Use the relevant regulator’s guidance and ask the contractor to explain the requirements for your property.
