What Is a CCTV Drain Survey?
A CCTV drain survey involves inserting a specialist high-definition camera into your drainage system to inspect the internal condition of pipes, joints, and connections. The camera transmits live footage to a monitor, allowing our engineers to identify blockages, cracks, root ingress, displaced joints, corrosion, and structural collapse in real time.
Surveys are used for diagnostics (finding the cause of drainage problems), pre-purchase inspections (assessing the drainage condition before buying a property), build-over surveys (required by water authorities before constructing over or near a drain), and planned maintenance (monitoring pipe condition over time).
The footage is recorded and used to produce a detailed written report documenting the condition of each section, including measurements, defect classifications, and recommendations. For homebuyer surveys, this report forms part of your due diligence and can be used in price negotiations.
CCTV surveys are non-invasive. No digging, no disruption, no damage to your property. The camera enters through existing access points — manholes, rodding eyes, or internal openings — and can inspect pipes from 50mm to 600mm in diameter.
Why Guessing at Drain Problems Costs You More
Without a CCTV survey, you are working blind. A slow-draining sink could be caused by a simple grease buildup, a collapsed pipe, tree root infiltration, or a displaced joint 20 metres from your property. Each cause requires a different solution at a vastly different cost.
Homebuyers who skip a drainage survey before purchase inherit problems they cannot see. Collapsed drains under driveways, root-damaged pipes beneath gardens, and shared drainage defects can cost £5,000–£15,000 to repair. A £200–£350 survey before exchange gives you negotiating leverage or the chance to walk away.
Developers and builders who proceed with construction near existing drains without a build-over survey risk prosecution by the water authority, mandatory demolition of the offending structure, and reinstatement of the drainage at their own cost. The survey costs a fraction of the potential consequences.
Repeated drain blockages are a symptom, not a diagnosis. Clearing the same blockage every few months without understanding the underlying cause wastes money and delays the permanent fix. A CCTV survey reveals whether you need a simple cleaning schedule, a targeted repair, or a section replacement — and stops the cycle of reactive spending.
How We Conduct a CCTV Drain Survey
Pre-Survey Consultation
We discuss the reason for the survey — diagnostic, pre-purchase, or build-over — to determine the scope, access requirements, and reporting format you need.
Access & Preparation
Our engineer locates and opens available access points. If drains are blocked or heavily silted, we clear them first to ensure the camera can travel the full length of each section.
Camera Inspection
We insert the HD camera and systematically inspect each drain run, recording footage of pipe condition, joint integrity, gradients, connections, and any defects encountered.
Report Compilation
We compile a detailed written report with annotated screenshots, defect descriptions, pipe measurements, and condition classifications. Homebuyer reports include a summary assessment suitable for solicitors and surveyors.
Recommendations & Next Steps
We explain the findings in plain language, outline any remedial work required, provide cost estimates for repairs, and answer your questions. You receive the full report and footage electronically.
Why Property Owners Trust Our CCTV Surveys
Accurate Diagnosis
HD footage reveals exactly what is happening inside your drains. No guesswork, no assumptions, no unnecessary work recommended without evidence.
Detailed Written Reports
Every survey produces a comprehensive report with annotated images, defect classifications, and clear recommendations — suitable for solicitors, insurers, and building control.
Homebuyer Protection
Our pre-purchase surveys have saved buyers thousands in hidden repair costs. Know exactly what you are buying before you commit.
Build-Over Compliance
We provide surveys that satisfy water authority requirements for building near or over existing drains, helping you avoid planning delays and enforcement action.
Non-Invasive
No digging, no disruption. The camera enters through existing access points and inspects your entire system without touching your property, garden, or driveway.
Same-Day Availability
For urgent diagnostics — ongoing flooding, pre-exchange deadlines, or insurance claims — we offer same-day survey availability where possible.
CCTV Drain Surveys: Methods, Equipment & Applications
We use two primary camera systems depending on pipe diameter and survey requirements. Push-rod cameras are flexible, high-definition units mounted on a semi-rigid cable that can navigate bends, junctions, and changes in direction within pipes from 50mm to 225mm diameter. These are the standard tool for domestic drainage inspections.
For larger-diameter pipes (225mm–600mm), commercial drainage systems, and long survey runs, we deploy crawler cameras — remote-controlled tracked units that travel independently through the pipe, providing stable, high-resolution footage over distances of 100 metres or more.
Survey types include condition surveys (assessing pipe structural integrity and defect severity), diagnostic surveys (locating the cause of a specific problem such as recurring blockages or subsidence), homebuyer surveys (pre-purchase assessments with solicitor-ready reports), and build-over surveys (mapping drain positions and conditions before construction).
We classify defects using industry-standard WRc (Water Research Centre) coding, which grades each defect by type and severity. This standardised system ensures our reports are understood and accepted by water authorities, building control, insurers, and other drainage professionals.
Common defects identified during surveys include fractured pipes, displaced joints, root ingress, scale buildup, deformation (particularly in pitch fibre pipes), corrosion in cast iron systems, void formation around pipes, and incorrect connections. Each defect type has specific remedial options ranging from targeted spot repairs to full section replacement.
For homebuyers, we recommend surveying all accessible drain runs before exchange of contracts. The survey identifies existing defects, estimates repair costs, and provides evidence for price renegotiation. In our experience, approximately 40% of pre-purchase surveys reveal defects that were not disclosed or identified by the standard building survey.
Build-over surveys are a legal requirement when constructing within 3 metres of a public sewer. The survey confirms the position, depth, and condition of the drain, and the resulting report is submitted to your local water authority as part of the build-over agreement application. Without this survey, your planning application will stall.
