What is A CCTV Drain Survey?
A CCTV drain survey is an internal inspection of a drainage system using specialist camera equipment. The camera is passed through accessible pipework to inspect its condition and record defects, restrictions, connections and other features that cannot be seen from the surface.
Rather than relying on assumptions or excavation, the survey provides clear evidence of what is happening underground and where any issues are located. CCTV surveys can identify:
Cracks and fractures
Displaced joints
Root ingress
Blockages and debris
Deformation
Collapsed pipework
Scale and deposits
Standing water and restrictions
What You Receive

Your survey can include:
WRc/MSCC5-coded drainage report
A professional record of the survey findings, with defects and observations clearly documented.Complete condition assessment
Identification of structural and service defects, including cracks, fractures, displaced joints, root ingress, deposits, restrictions and other issues.Annotated drainage map
A clear plan showing surveyed pipe runs, chambers, connections and direction of flow where these can be established.High-definition CCTV footage and images
Recorded survey footage with supporting images of significant defects and observations.Clear identification of significant issues
Important defects are highlighted so you can quickly understand what requires attention.Practical recommendations
Straightforward advice on whether cleaning, repair, monitoring or further investigation is recommended.
Where access is restricted or a section of drainage cannot be surveyed, this will also be clearly recorded within the report.
When Do You Need a CCTV Drain Survey?
You may need a CCTV drain survey when there is a risk of hidden issues within your drainage system or when confirmation of condition is required before making a decision.
If you are unsure whether you need a CCTV drain survey, our team can advise based on your situation and property type.
Most common reasons include:
Buying a property
A CCTV drain survey is highly recommended when purchasing a property. Standard building surveys do not assess underground drainage, meaning defects can go unnoticed.
We regularly find issues during homebuyer surveys, that would cost thousands if missed. A survey helps you:
Identify hidden issues before committing
Avoid unexpected repair costs
Support price negotiations where problems are found
Building Works or Extensions
Before carrying out construction or extensions, a drain survey helps you understand the location and condition of existing pipework and is required to get sign-off from your water authority.
This is important for:
Avoiding damage during works
Supporting build-over approvals
Reducing risk during construction
Recurring Blockages or Drainage Issues
If you are experiencing repeated blockages, slow drainage, or foul odours, a CCTV survey identifies the root cause.
This ensures:
Accurate diagnosis of the problem
Targeted repairs rather than temporary fixes
Mortgage or Insurance Requirements
Some lenders and insurers may request a drainage survey to confirm the system is in good condition. A professional report provides reassurance and can help prevent delays.
After Flooding or Ground Movement
If you suspect damage within your drainage system, a CCTV survey provides a clear diagnosis. Identifying issues early helps prevent more serious and costly problems.
How does a CCTV drain survey work?
We keep the survey process straightforward, with the scope agreed around the property, site and reason for the inspection.
1. Agree the survey scope
We review the available information and confirm which areas of drainage need to be inspected, along with any specific reporting or mapping requirements.
2. Carry out the CCTV inspection
Our engineer accesses the drainage system through suitable chambers and inspection points, then uses specialist CCTV equipment to inspect the accessible pipework internally.
3. Record the drainage system
During the survey, we record defects, pipe condition, chambers, connections, flow direction and other relevant drainage information where these can be established.
4. Review and report the findings
The survey footage is reviewed and the findings are presented within a clear drainage report, supported by CCTV images, footage and an annotated drainage map.
5. Explain the next steps
Any significant defects or restrictions are highlighted, with practical recommendations for cleaning, repair, monitoring or further investigation where required.
If access is restricted, drainage is heavily blocked or part of the system cannot be inspected, this will be clearly identified within the report.
How much does a CCTV drain survey cost?
The cost of a CCTV drain survey depends on the size of the drainage system, the reason for the survey and the level of reporting or mapping required.
As a guide:
Localised CCTV inspections: from £150 + VAT
Residential CCTV drain surveys: from £250 + VAT
Commercial and larger site surveys: quoted based on scope
Factors that can affect the price include:
The number of drains and chambers to be inspected
The overall length and complexity of the drainage system
Site access and working conditions
Whether drainage mapping is required
The level of reporting needed
Any cleaning or clearance required before the drainage can be fully inspected
We provide a clear quotation before attending so you know exactly what is included.
Comparing Drain Survey Quotes
Not all CCTV inspections provide the same level of information.
A basic camera inspection may identify an immediate problem, but a full drainage survey should provide a clear record of the system, supporting footage and images, condition information and practical recommendations.
When comparing quotations, it is worth checking whether the price includes professional reporting, drainage mapping, recorded footage and a full assessment of the findings.
