CCTV Drainage Survey

The time required depends on the property size, drainage layout, number of pipe runs and ease of access. A straightforward domestic system can often be inspected during one visit, but larger or more complex networks take longer. Blockages, restricted access or heavily soiled pipework may also delay the inspection. UKDP confirms the survey requirements before the visit and explains if any additional investigation is needed.

Not always. A camera can inspect pipework when the route is sufficiently clear and the internal surface is visible. However, standing waste, grease, scale or a substantial blockage can obstruct the camera or hide defects. In these circumstances, cleaning may be required before the survey can continue. UKDP will explain whether clearance is needed and why it would improve the quality of the inspection.

The camera may be unable to continue if it reaches a blockage, collapsed section, tight bend or inaccessible connection. The survey will record how far the camera travelled and what prevented further inspection. UKDP can then recommend the appropriate next step, such as clearing the obstruction, using another access point or carrying out further investigation before the remaining pipework can be assessed.

The camera records where a defect appears within the inspected pipe run and its distance from the access point. Confirming the precise position above ground may require additional tracing equipment, especially where drainage plans are unavailable or the pipe route is unclear. UKDP will explain what the footage establishes and whether tracing or another investigation is required to confirm the defect’s location and depth.

Yes, provided the damaged section remains accessible to the camera. The footage may reveal severe fractures, deformation, displaced pipework, soil entering the drain or a section the camera cannot pass. A blockage can sometimes prevent a complete view of the suspected collapse. UKDP assesses the available evidence and explains whether it confirms structural failure or whether cleaning or further investigation is needed.

Yes. The camera can show roots that have entered accessible pipework through a crack, damaged joint or another opening. The survey records the location and extent of the visible root ingress, along with any damage around the entry point. UKDP can then explain whether the roots should be removed and whether lining, excavation or another repair is needed to reduce the risk of regrowth.

A CCTV survey can identify visible defects that may allow water to escape, including cracks, fractures, open joints and displaced connections. However, the camera may not always show water passing through a small or concealed defect. UKDP will explain what the footage confirms and may recommend another test or investigation when a leak is suspected but cannot be established from the camera inspection alone.

A CCTV survey can provide recorded evidence of visible drainage damage and help an insurer assess its cause and extent. Customers normally pay for the survey themselves because its cost often falls within the policy excess. The insurer may cover the survey when it has appointed UKDP directly to investigate reported damage, subject to the terms of the individual policy.

In many cases, yes. Patch lining or full-length lining can create a new internal layer within suitable existing pipework, avoiding the need to dig up the entire drain. However, lining is not appropriate for every defect, particularly where a pipe has completely collapsed or lost its shape. The CCTV findings allow UKDP to assess the damage and recommend lining, excavation or another suitable repair method.

Private drains within the property boundary are generally the owner’s responsibility. Shared sewers and pipework beyond the boundary are often the responsibility of the local water company. Ownership can depend on where the defect is located and which properties the pipe serves. A CCTV survey can help establish the position of the problem, while drainage plans or water company records may be needed to confirm responsibility.

Only pipework that is accessible and can be safely navigated by the camera can be inspected. Blockages, collapsed pipes, tight bends, inaccessible chambers or the drainage layout may restrict some sections. The report will identify what was inspected and record any limitations encountered. UKDP can then advise whether cleaning, another access point or further investigation is needed to examine the remaining pipework.
