How long does a drain survey take—and when do you get the report?

If a solicitor, surveyor or designer needs the findings by Friday, ask when they need the completed report, not just when an engineer can attend. Allow time for that person to read it and raise questions.

A Monday visit with an unspecified report date does not establish that you can rely on the document later that week. Ask for both dates in the booking confirmation and say explicitly if a purchase or building decision depends on them.

DASA identifies longer pipe runs, difficult access and clearance as reasons a domestic survey may take longer than its typical one-to-two-hour estimate. Ask the contractor to estimate your job from the property details rather than copying that range into your diary.

Tell the contractor about extensions, outbuildings, known covers, earlier blockages and any area that cannot be accessed. If you have a previous plan, offer to send it before the appointment.

For a house purchase, coordinate the appointment with the seller or agent and establish who is giving permission. Confirm how the engineer enters the property and reaches the agreed inspection points.

Keep pets away from the working area and tell the contractor about locked gates or covers hidden by stored items. Leave lifting heavy or suspect covers to the contractor. Ask what you can safely clear in advance instead of attempting drainage work yourself.

Ask whether a blockage needs clearance before the camera can continue and who authorises the additional work. Agree whether the contractor should call you before incurring extra cost.

If part of the system remains inaccessible, ask for that limitation in the report and an explanation of the next step. A short visit could mean a straightforward job, but it could also mean the camera was stopped early. Duration alone does not establish coverage.

Confirm whether the booking includes a written report, footage, photographs and any drawing you need. A verbal explanation at the property is different from a document another professional can review.

Ask how files will be delivered, whether download links expire and who answers follow-up questions. DASA distinguishes a basic inspection from its full report package; check your contractor’s own inclusions rather than assuming every CCTV booking is identical.

If the report recommends work, leave room to review the evidence and obtain a defined repair quote. Do not book a large non-urgent repair solely because a contractor is already on site.

Where shared-pipe responsibility is uncertain, contact the sewerage company before treating the recommendation as your private bill. Our quote comparison helps record missing information; it does not rank contractors or turn unknown extras into a final total.
