What Is a CCTV Drain Survey?
A CCTV drain survey uses a specialist camera to inspect the inside of the accessible drainage pipes at your home or business. This allows us to see what is happening below ground without immediately excavating the pipework.
The camera can help identify visible problems such as:
- Blockages and accumulated waste
- Grease, scale and other build-up
- Tree-root intrusion
- Cracked or fractured pipes
- Collapsed or deformed sections
- Displaced, open or misaligned joints
- Corrosion and general pipe deterioration
- Visible leaks or water infiltration
- Poorly installed or misaligned pipework
Once your drain CCTV survey in London is complete, we will explain what we found, answer your questions and recommend the most appropriate next step.
What Happens During a CCTV Drain Survey?
1. We discuss why you need the survey
You tell us what has prompted the inspection, whether it is a recurring blockage, suspected damage, property purchase or planned building work.
2. We inspect the pipework
We guide the camera through the accessible drains and review the footage in real time to locate visible blockages, damage or other faults.
3. We explain what we find
We talk you through the footage, answer your questions and explain whether cleaning, repair, drain lining or further investigation may be needed.
4. You receive a detailed drainage report
Your report records what was inspected, the faults identified and the recommended next steps, giving you a clear record of the drain’s condition.
5. You decide how to proceed
Where repairs or drain cleaning are needed, we can provide a separate quotation and explain the available options. No remedial work is carried out until you understand the recommendation and give us the go-ahead.
Reasons to Book CCTV Drain Surveys in London
A Drain Problem Keeps Coming Back
If a drain keeps blocking after it has been cleared, there may be a deeper problem inside the pipe. Our CCTV Drain Surveys London service allows us to inspect the drainage system and identify what may be causing the issue.
A survey may be useful if:
- The same drain repeatedly blocks or runs slowly
- Several sinks, toilets or showers are affected
- Wastewater backs up into another fixture
- Gurgling noises or unpleasant smells keep returning
- Previous drain cleaning only solved the problem temporarily
- You notice unexplained wet patches or signs of a possible leak
The CCTV footage gives us a clearer picture of what is happening inside the drain. This makes the drainage investigation more accurate and helps us decide whether cleaning, repair or drain lining is the right next step.
Buying a Home or Commercial Property
Drainage problems are often hidden underground and may not be identified during a standard property viewing. A pre purchase drain survey gives you a clearer understanding of the accessible drainage system before you commit to the purchase.
Without one, you could inherit problems that may lead to:
- Recurring blockages and wastewater backing up into the property
- Unpleasant smells or damp caused by leaking or damaged drains
- Unexpected repair costs soon after moving in
- Disruption from excavation, drain lining or other remedial work
- Delays to planned renovations or extensions
- Disputes over who is responsible for existing drainage defects
Our home buyers’ drain survey includes a detailed drainage report explaining what was inspected, any faults found and the recommended next steps. This helps you understand the likely work involved and make a more informed decision before proceeding with the purchase.
Property Extensions
Before extending or altering your property, it is important to understand where the drains run and whether the proposed work is close to a public sewer or lateral drain.
For properties served by Thames Water, a build-over application is likely to be required when building within 3 metres of a public sewer or 1 metre of a public lateral drain. The exact requirements depend on the drainage layout and the type of project.
A camera drain inspection can help you:
- Check the condition of accessible drains before construction begins
- Identify damage that may need attention before it is built over
- Provide drainage information for the application or project team
- Record the condition of the pipework before and, where required, after the work
- Reduce the risk of unexpected drainage problems disrupting the project
Where the project is close to a public sewer or lateral drain, additional information or approval may be required before construction begins.
CCTV Drain Surveys for Landlords and Managing Agents
A drainage problem in a rental building can disrupt tenants, affect shared areas and, in some cases, cause wastewater damage or damp. A targeted drainage investigation can help you establish where the problem is and whether it affects one property or a shared section of the system.
A CCTV drain survey can help you:
- Understand whether a fault could affect more than one flat or unit
- Address recurring problems before they cause further disruption or property damage
- Plan necessary maintenance or repairs based on evidence rather than assumptions
- Keep a detailed record of the drainage condition and any faults identified
You will receive a detailed drainage report setting out what was inspected, what was found and the recommended next steps. Where cleaning or repairs are needed, we can provide a separate quotation for you to review before approving any further work.
A Real Example of Our CCTV Drain Survey Work
The Problem
Kati’s shower drain kept filling with water while she showered, creating a risk of it overflowing into the bathroom. The cause of the blockage was not clear from the surface.
What We Did
Chris carried out a CCTV drain inspection to locate the obstruction and check the condition of the pipe. The camera footage showed a build-up of hair and soap scum inside the drain, confirming that the problem was caused by an obstruction rather than damaged pipework.
Once the cause had been identified, Chris cleared the blockage and tested the shower to make sure the water was draining away properly.
The Result
The shower was draining freely again, and Kati was pleased with Chris’s punctuality, professionalism and clear advice.
“Chris is professional and was there on time. I am very happy with his work and advice and will certainly recommend him.”

Most CCTV drain surveys take around one to two hours, although this can vary depending on the size and layout of the drainage system, available access and whether blockages make parts of the pipework difficult to inspect.
Larger properties, commercial sites or more complex drainage systems may take longer. Additional time may also be needed to prepare your detailed drainage report.

Yes, a CCTV drain survey is worth it when you need to understand the cause or condition of a drainage problem before deciding what to do next. It can identify visible blockages, cracks, root intrusion, displaced joints and other faults without immediately excavating the pipework.
It is especially useful when a drain keeps blocking, you are buying a property, planning building work or assessing drainage at a rental or commercial property. The findings can help you avoid unnecessary work, understand the likely repair requirements and make a more informed decision.
Yes, a drain survey is usually worth having before buying a property, particularly if the building is older, the drains have a history of problems or you are planning renovations. Standard property surveys do not normally provide a detailed inspection of underground drainage pipes.
A pre-purchase drain survey can identify visible blockages, cracks, root intrusion, displaced joints and other faults before you commit to the purchase. The drainage report can help you understand potential repair costs, raise questions with the seller and make a more informed decision.
Yes. CCTV surveys are commonly used to locate blockages and identify what is causing them. Once we have diagnosed the problem, we can clear the blockage and continue feeding the camera through the pipework to confirm that it has been fully removed.
This allows us to find and address the underlying cause, helping prevent the blockage from returning. We can also check for damage such as cracks, displaced joints or tree-root intrusion.
If you booked the survey for another reason and we encounter a blockage, it may need to be cleared before we can inspect the rest of the drainage system. This will depend on the type and severity of the blockage, as the camera may be able to pass through some partial obstructions. We will explain what we have found and discuss any additional work or cost with you before proceeding.
A CCTV drain survey checks the internal condition of your drains, while drain mapping shows where the drains run and how the different sections connect.
During a CCTV survey, a camera is fed through the pipework to identify blockages, cracks, root intrusion, displaced joints and other visible faults. Drain mapping uses the survey findings and access points to create a plan of the drainage network, including the route and connections between pipes.
A standard CCTV survey is usually suitable when investigating a drainage problem or checking pipe condition.
Drain mapping may be needed for extensions, construction work or projects where the exact layout of the drainage system must be understood.
A drain survey is strongly recommended before building an extension and may be required if the work will be over or close to a public sewer or lateral drain. It helps establish where the drains run, checks their condition and identifies any damage that should be repaired before construction begins.
For properties in the Thames Water area, building work within 3 metres of a public sewer or 1 metre of a public lateral drain may require a build-over agreement. Depending on the sewer and proposed work, CCTV surveys may be required before and after construction to confirm its condition and check that the building work has not caused damage.
If the CCTV survey finds damaged pipework, we will explain the fault, show you the relevant footage and recommend the most appropriate next step.
Depending on the type and extent of the damage, this may involve drain cleaning, a localised repair, drain lining or replacing the affected section. You will receive a separate quotation for any remedial work, and nothing will proceed until you understand the options and approve the work.
