Check who owns the affected asset and who can authorise work. Public sewer, highway and landlord reports have separate direct routes. Do not rely on this form for emergency help. Local reporting contacts are below; this enquiry service does not provide emergency dispatch.
What is a CCTV drain survey?
A camera survey records accessible internal pipework. Specify the purpose before booking: recurring blockage, condition before buying, repair verification or location for planned works. Ask for the length, access points and reporting standard included. A camera cannot inspect beyond an obstruction or prove every concealed connection simply because it travelled through one run.
When do I need a CCTV drain survey?
A survey is useful when it answers a defined question that clearance or visible checks cannot settle. A repeat blockage may need the cause investigated; a planned extension may need the sewer route and ownership established. If sewage is currently overflowing, direct reporting and immediate containment come first. Agree whether cleaning is needed before usable images can be obtained.

What can a CCTV drain survey find?
Footage may show deposits, roots, cracks, joint displacement or standing water. Interpretation needs the pipe's position, direction and inspection limits. A defect somewhere in the system does not automatically explain the symptom. Ask for findings tied to a drawing or measured run and for uncertainty to be recorded instead of presented as a certain diagnosis.
CCTV drain survey cost
Compare surveyed scope and output: camera footage alone differs from a written condition report with a plan and recommendations. Ask about clearance, location equipment, lengths, inaccessible runs, VAT and follow-up explanation. For a purchase, agree the report with your adviser beforehand. Do not assume an inexpensive inspection includes every drain or public-sewer record.
How long does a CCTV drain survey take?
The time needed varies with access, cleaning, bends, surveyed length and the report required. Confirm whether the report comes separately and what happens if a run cannot be reached. Allow safe access without moving heavy covers yourself. An incomplete survey should identify the missing areas and explain how that changes the usefulness of its conclusions.
Drain survey before buying a house
Before buying, ask what the survey covers and which drains lie outside the seller's control. Read it alongside drainage searches and property information. Colchester's historic-centre designation makes proposed excavation a separate planning consideration; it is not evidence that the drains are faulty. Ask an adviser about material concerns before exchange rather than relying on a vague pass/fail label.
Homebuyer drain surveys
A useful homebuyer instruction names the property, access permission, drains to inspect and the intended report recipient. Ask for findings ranked by evidence and significance, repair options and any uninspected sections. The seller's access arrangements and sewer ownership can limit work. No report can guarantee a property will never develop a blockage or hidden defect.
Finding collapsed drains
A camera may stop at a suspected collapse. The report should distinguish what is seen from what is inferred and show the last confirmed position. Further locating or excavation may be needed to establish the defect. Ask how the next step avoids unnecessary digging and whether public assets, utilities or heritage-sensitive ground are involved.
Finding cracked drain pipes
Cracks should be shown with their position and context, not a cropped image without a run reference. Ask whether leakage or loss of service was assessed and what uncertainty remains. The significance of a crack depends on the actual pipe and fault. Repairs should follow an interpreted finding and ownership check rather than a generic age-based recommendation.
Finding tree roots in drains
Roots seen on camera identify intrusion into the inspected pipe, not necessarily the responsible tree or the remedy outside it. Ask how the entry point is recorded and what pipe repair is needed after removal. Confirm protected-tree and ownership constraints if external root work is proposed. Removing a tree should not be assumed to repair a leaking joint.
Finding recurring blockages
Keep previous clearance details so the survey can concentrate on why the fault returns. Clean enough of the run for meaningful inspection where safe and appropriate. Ask whether the report identifies deposits, structural defects or other limitations. The next maintenance or repair step should explain its connection to the repeat pattern rather than list every minor observation equally.

Locating underground drains
Camera distance readings alone may not give a reliable ground position. Ask whether a sonde or another locating method is included and what accuracy or limitations apply. Plans should distinguish confirmed routes from assumed connections. For excavation in Colchester, utility searches and heritage/archaeology checks remain separate; a camera survey does not clear every ground-work constraint.
CCTV survey after drain repairs
A post-repair survey should identify the repaired section, show its completed condition and record connections and flow observations within its scope. Compare the result with the agreed specification and original defect. Ask for remaining limitations and handover records. A photograph of equipment at the property is not the same as evidence that the relevant repaired run was inspected.
Useful next steps
Do I get a drain survey report?
Agree the deliverables in advance: dated footage, access points, direction, run lengths, a plan, findings and recommendations. The report should say what was not reached and why. Use the illustrated checklist below to compare offers. It is an editorial checklist, not a real Colchester survey or proof that a provider follows a particular reporting standard.
- Purpose and agreed surveyed runs.
- Plan reference, direction, length and access points.
- Dated footage and interpreted findings.
- Unreached sections and their effect on conclusions.
- Repair options with reasons, separate from the observation.
Do I need a CCTV survey before building an extension?
For an extension, establish public sewers, drain routes, proposed loads and access before design is final. Ask Anglian Water about build-over or nearby sewer requirements, and Colchester about the separate building-control and heritage questions. A CCTV report alone is not permission to build. Unmapped assets and restricted survey access may require additional investigation.
