Short answer: A CCTV drain survey uses a camera passed through accessible pipework to inspect the inside of a drainage system. It can help identify the location and apparent condition of a blockage, crack, root ingress or other defect without excavating the pipe simply to look inside. The findings help determine what action, if any, is appropriate.
What does a CCTV drain survey check?
A drain camera inspection can show visible conditions inside the surveyed section of pipe. Depending on access and pipe condition, this may include debris or obstructions, cracks, displaced joints, root ingress, standing water or signs of wear. A survey is a visual inspection of the accessible drain, not a guarantee about every pipe or hidden part of the wider drainage system.
When should I book a CCTV drain survey?
A survey may be useful when blockages keep returning, several fixtures are affected, there is a persistent drain odour, or a repair needs to be planned. It can also help investigate suspected pipe damage or provide information about a drainage system before building work. For a first-time, straightforward blockage, a camera survey may not be necessary; the right next step depends on the symptoms and the technician’s assessment.
If slow drainage or repeat blockages are the issue, first consider blocked drain clearance. A survey can then be recommended if the cause is not clear or the problem returns.
How does a CCTV drain survey work?
- Access: The technician identifies a suitable access point, such as an inspection chamber, where available.
- Inspection: A camera is guided through the accessible pipe while the technician views the footage.
- Assessment: Visible issues are noted, and the survey may help locate where they occur along the inspected section.
- Next steps: The findings are explained so you can consider whether cleaning, repair, further inspection or no immediate work is appropriate.
Access, blockages, pipe condition and the layout of the system can affect how much of a drain can be inspected. Your technician should explain any limitations encountered during the survey.
What should a drain survey report include?
A useful report explains which sections were inspected, the visible findings and any limits to the inspection. It may include images or video and recommendations based on what was seen. Ask the provider to explain technical terms and distinguish observed defects from suggested follow-up work.
Does a CCTV drain survey clear a blockage?
No. A camera survey is an inspection, not a cleaning method. If debris is preventing the camera from progressing or the pipe needs cleaning, the obstruction may need to be cleared separately. Depending on the findings, suitable professional drain cleaning may be recommended before or after an inspection.
Will a CCTV drain survey mean my garden or driveway is dug up?
The camera inspection itself is designed to view accessible pipework from an access point and does not usually require excavation just to see inside. If a defect is found, the repair options depend on its position, extent, pipe condition and access. A survey can help inform that decision, but it does not guarantee that excavation will never be needed.
How do I arrange a CCTV drain survey?
Describe the symptoms, how long they have been happening and whether previous blockages have returned. That information helps the drainage team advise whether a camera inspection is a sensible next step.
