Professional CCTV camera inspections with detailed written reports — for homebuyers, landlords, insurance claims, and persistent drainage problems across London.
See exactly what’s inside your drainage system
A CCTV drain survey is the only reliable way to find out what is happening inside your pipes. HydraFlow uses professional push-rod and crawler cameras to inspect drainage systems across London, producing clear footage and written reports for homebuyers, landlords, property managers, and insurers.
If you have a recurring blockage, unexplained smells, suspected structural damage, or are buying a property — a CCTV survey gives you facts, not guesses.
What happens during a CCTV drain inspection
A waterproof camera head on a flexible push-rod is fed into your drainage pipes through an existing access point. The live footage is recorded in real time, then combined with a written defect log, location measurements, still images, and clear remediation recommendations.
When do you need a CCTV drain survey?
Buying a property
Standard building surveys skip the drains. Collapsed sections or root intrusion can cost thousands. A pre-purchase survey gives you negotiating power or peace of mind.
Recurring blockages
If the same drain blocks every few months, rods are not solving the real problem. The camera reveals exactly why — root growth, structural defects, or inadequate fall.
Subsidence investigation
Drain leaks wash away bedding beneath foundations, causing ground movement. A survey can confirm or rule out drainage as a contributing factor to cracks or uneven floors.
Insurance claims
Many insurers require video evidence when processing drainage-related claims. Our reports are accepted by major UK insurers and formatted to their requirements.
New build sign-off
Confirm new drainage is correctly laid, at the right gradient, and free of debris before the ground is reinstated — avoiding expensive excavation later.
Landlord due diligence
Periodic surveys identify developing issues before they become emergency callouts. A report also provides a baseline record for tenancy management.

Frequently Asked Questions – CCTV Drain Survey
How long does a CCTV drain survey take?
A typical residential survey takes between 1 and 2 hours. The written report is usually provided within 24–48 hours of the survey.
Do I need to be present during the survey?
It is useful if you are present so the engineer can explain findings in real time, but it is not essential. We will send a full written report regardless. For pre-purchase surveys on an empty property, we just need access or a key from your estate agent.
What happens if the survey finds a defect?
We will explain the defect, its severity, and your options in plain language. Not every defect requires immediate repair. Where repairs are needed, we provide a clear, itemised quote. You are never under any obligation to use us for the remediation work.
Can you survey drains under a concrete floor or driveway?
Yes — the camera is inserted through an existing access point and can traverse the pipe regardless of what is above it. We can inspect pipes beneath driveways, patios, and building slabs without any excavation.
