HD camera drain inspections across all 32 London boroughs — identify blockages, root ingress, and structural faults without excavation. Same-day surveys available.
Free, no-obligation — we'll call you back fast.
Across London properties, we attend a consistent set of issues for this service. We explain the cause clearly before recommending any work.
Every visit follows the same structured process. As a result, you receive a consistent standard of work whether the job is a quick clearance or a multi-stage diagnostic survey.
A CCTV drain survey uses a waterproof high-definition camera mounted on a flexible rod to inspect the interior of your drainage system from inside the pipe. The camera is fed through an access point — usually a manhole, inspection chamber, or rodding eye — and advances through the drain run, transmitting live footage to a monitor at ground level.
The engineer identifies defects as they appear: root infiltrations growing through joints in Victorian clay pipes, displaced or offset sections where ground movement has separated connections, cracks and fractures, scale and grease build-up, and blockages. Everything is recorded, and the report documents each defect with its location, severity grading, and recommended action.
The majority of London's residential drainage network consists of Victorian-era clay pipes, typically 100mm in diameter, installed between the 1860s and early 1900s. After 120–150 years, these pipes develop cracks, root intrusions, and joint displacements at rates far exceeding modern drainage. London Clay — the dense, expansive geological layer beneath most of inner London — shrinks in summer and swells in winter, applying lateral stress to buried pipes that accelerates joint separation.
According to Thames Water, approximately 60% of drainage call-outs in London involve structural pipe defects rather than purely blockage causes. This means clearing a drain without surveying it first often means the blockage will recur, because the underlying structural fault is never identified or repaired.
A standard building survey does not inspect underground drainage. For any London property built before 1960 — the majority of Victorian terraces, Edwardian semis, and inter-war homes that make up most of the capital's housing stock — a pre-purchase CCTV drain survey is strongly advisable before exchange of contracts.
A pre-purchase report is small relative to the repair bills that undisclosed drainage defects can produce: a collapsed lateral drain under a garden typically costs £2,000–£5,000 to repair; root infiltration along a shared run can require relining at £1,500–£4,000. A pre-purchase survey report is accepted by solicitors, mortgage lenders, and insurers as evidence of drainage condition.
We deliver written survey reports within 24–48 hours of the inspection, including HD video footage and still images of any defects. Reports are produced to WRCm grading standards, accepted by solicitors, insurers, and mortgage lenders. For homebuyers with tight exchange deadlines, same-day verbal reports are available on request.

We carry out CCTV drain surveys across London boroughs. For dedicated local coverage in South London, see our CCTV drain surveys in Croydon page, which covers homebuyer checks, recurring blockages, and pipe defect diagnosis for Croydon properties.
We identify the nearest suitable access point — manhole, inspection chamber, or rodding eye — and confirm the survey scope with you before introducing any equipment into the drain.
Our HD camera advances through the drain run at a controlled pace. Defects are noted with location and WRCm classification as they appear, and all footage is recorded.
We deliver a written WRCm-graded report with HD video and still images within 24–48 hours, with repair recommendations prioritised by severity.

Commercial CCTV drain surveys for London restaurants, offices, hotels, HMOs, care homes, and managed estates — written WRCm reports accepted by managing agents, insurers, and Thames Water.
A CCTV drain survey in London costs from £150 for a basic single-run inspection with verbal findings, to £300–£450 for a comprehensive pre-purchase survey with a solicitor-ready written report, HD video footage, and condition grading. The full price guide is on our CCTV drain surveys cost page.
A CCTV drain survey identifies root infiltrations, cracked or fractured pipe walls, displaced joints where ground movement has separated connections, scale and grease build-up, collapsed sections, and blockages. In London's Victorian clay drainage, root ingress and joint displacement are the two most common findings.
A basic survey of a single drain run typically takes 30–60 minutes on site. A comprehensive survey of a full drainage system at a London terrace or flat takes 60–120 minutes, depending on the number of runs, access points, and complexity of the layout. The written report is delivered within 24–48 hours.
For any London property built before 1960, a pre-purchase CCTV drain survey is strongly recommended. Standard building surveys do not inspect underground drainage. Victorian clay pipes are prone to root infiltration and joint displacement that can cost thousands to repair — a £300–£450 survey identifies these issues before exchange of contracts.
Yes. A CCTV drain survey report produced to WRCm standards is a recognised document in property purchase negotiations. If defects are found, the report provides clear evidence to request a price reduction or require the vendor to carry out remediation before exchange.
With London house prices among the highest in the UK, a CCTV drain survey costing a few hundred pounds can protect you from thousands in repair costs. Here's why it matters.
