CCTV Drain Surveysin Stowmarket.

What is a CCTV drain survey?

Quick answer

Request a CCTV drain survey for a house purchase, repeated blockage or proposed building work, with a report suited to your purpose.

A CCTV survey examines accessible drain interiors using a camera. Specify whether you need a diagnostic check, a formal report, location mapping or evidence for planned work.

When do I need a CCTV drain survey?

Consider a survey for persistent blockages, suspected damage, a property purchase or planned works affecting drainage. Tell the surveyor the question you need answered. An inspection commissioned to locate a blockage may not meet the reporting needs of a buyer or building proposal.

What can a CCTV drain survey find?

A useful survey records visible condition and limits such as obscured or inaccessible lengths. It cannot certify ground bearing, present flood risk or ownership simply from footage. Tell the surveyor whether the question is condition, recurring blockage or proposed building clearance.

CCTV drain survey cost

Ask whether the quote includes…

Specify whether locating, cleaning needed for camera access, interpretation and a written report are included. A camera pass is not automatically a complete mapped drainage survey; ask who can use the deliverables and what further checks may be needed.

• All relevant accessible drain runs.
• Cleaning needed for camera visibility.
• Footage and a written report in the format you need.
• Location mapping and VAT.

How long does a CCTV drain survey take?

The time depends on the network, access and whether cleaning is required for visibility. Tell the surveyor about locked gates, concealed covers and previous extensions. Confirm when the written report will arrive as well as how long the visit is expected to take.

Drain survey before buying a house

Before a purchase, agree the extent of inspection and deliverables with your adviser. Request a record of accessible runs, defects, uncertainty and any recommended further work. A visually clear pipe is not proof that all drainage responsibilities have been resolved.

Homebuyer drain surveys

Give the surveyor the property, purchase deadline and questions raised by the conveyancer or building survey. Check whether tracing, footage and a written report are included. Keep uninspected lengths explicit rather than assuming a complete drainage plan.

Finding collapsed drains

Quick answer

If a camera cannot pass an obstruction, ask what supports a diagnosis of collapse. The report should state where inspection stopped and how the suspected defect was located.

Finding cracked drain pipes

Ask for images, location and an explanation of the significance of a reported crack. Visibility can be limited by deposits or water. Confirm whether the pipe was clean enough to assess and whether the defect is linked to the symptom that prompted the survey.

Finding tree roots in drains

A report should show the roots, the affected distance and any visible entry point. Discuss clearance and repair separately. If roots prevent a complete inspection, a further survey after removal may be needed to understand the remaining pipe condition.

Finding recurring blockages

Give the surveyor dates, affected fixtures and earlier clearance records. Inspection is often most informative once sufficient flow and visibility have been restored. Ask for recommendations that explain why blockages return rather than just a list of visible observations.

Locating underground drains

Quick answer

Camera inspection does not automatically include locating or a drainage plan. Agree whether depth, route marking and mapping are included before relying on the survey for building work.

CCTV survey after drain repairs

After repair, ask for evidence that the specified area has been treated and flow checked. Agree this in the original scope so it is not an unexpected extra. Keep the footage and written record alongside the repair invoice and warranty.

Do I get a drain survey report?

Confirm the deliverables

Check any required format with your builder, insurer or conveyancer before commissioning the survey.

This fictional example shows how to read survey findings. Your surveyor’s report may use a different format; check what you will receive before commissioning the survey.

Notice how the example separates what was seen from what could not be inspected. A distance along a pipe is useful, but it may need route locating to identify where that point lies under a garden or driveway. A recommendation should explain the remaining uncertainty rather than converting every observation into an immediate repair order.

• Footage and findings you can understand.
• Inspected lengths and any inaccessible sections.
• Location information, where commissioned.
• Limitations and recommendations.

Do I need a CCTV survey before building an extension?

Establish sewer position and ownership early in an extension design. Ask the designer what location and condition evidence is needed; a CCTV inspection and Anglian Water’s build-over assessment are different steps.
