How it works in SW15
What a CCTV drain survey involves
Camera insertion
A small waterproof camera on a flexible push rod is fed into the drain — typically through a manhole or rodding eye. The camera head transmits live footage to a monitor and recording unit above ground. Both drainage pipes serving sinks, baths, and showers and surface water drains can be inspected during the survey.
Defect location by sonde
As the camera travels through the pipe, the operator identifies and records every defect in real time. The camera sonde transmits a signal to a locator above ground, allowing the exact position and depth of any defect to be marked at the surface — enabling targeted excavation if repair requires access.
Written report and video
Every survey produces a written report with still frames and a full video recording of the drain run. Defects are identified with WRC Manual of Sewer Practice condition codes — the standard used by water companies and insurers. The report and video are delivered digitally or on USB for use in conveyancing, insurance, and repair quotes.
Reasons to book in SW15
When do you need a CCTV drain survey?
Recurring blockages
A blockage that returns within weeks of clearing is a structural problem, not a debris problem. CCTV reveals whether root intrusion, a collapsed section, or incorrect fall is the cause — issues that jetting alone cannot resolve permanently.
Pre-purchase drain survey
Drain surveys are increasingly standard in London property purchases, particularly for older terraced houses and Victorian conversions. A survey before exchange reveals defects the buyer can use to negotiate a price reduction or require the vendor to repair before completion.
Slow draining without obvious blockage
Slow drainage that does not respond to standard drain products often indicates a partial restriction from displaced joints, root intrusion, or a section of pipe with inadequate fall. CCTV confirms the cause and location so the correct repair can be specified.
Damp in walls or floors near drains
Cracked drain pipes allow wastewater to infiltrate the surrounding soil and eventually the building fabric. If damp appears near a drain run, CCTV survey confirms whether a broken pipe is the source before unnecessary damp-proofing works are commissioned.
Post-blockage condition check
After a blockage has been cleared by jetting, a CCTV survey confirms the pipe is fully clear and checks structural condition. A drain that has been jetted but not surveyed may re-block within weeks if the underlying defect is not identified and repaired.
Pre-lining assessment
Before committing to no-dig drain relining (CIPP), a CCTV survey confirms whether the pipe is suitable — adequate pipe wall remaining, no major collapses, correct dimensions for the liner. A survey prevents relining failures by verifying suitability in advance.

Services in SW15
CCTV drain survey services
Pre-Purchase Drain Survey
Essential before buying a London property. Victorian clay drains are prone to root intrusion, collapse, and joint displacement. A CCTV survey reveals defects before exchange of contracts, giving buyers leverage to negotiate repairs or a price reduction.
Recurring Blockage Investigation
When a blockage keeps returning after clearing, CCTV reveals why. Root intrusion, collapsed sections, and incorrect fall all cause recurring blockages that cannot be cleared permanently without structural repair.
Drain Survey and Written Report
Every CCTV drain survey produces a written report with still frames and video footage. Defects are coded to WRC Manual of Sewer Practice standards. The report is used for insurance claims, conveyancing, and as evidence for remedial work quotes.
Combined Jetting and CCTV
High-pressure water jetting first to clear the drain, then CCTV survey to confirm clearance and check pipe condition. The most comprehensive drain service — identifies both the cause of the blockage and any structural defects.
Drain Relining Assessment
If CCTV reveals cracked, displaced, or root-intruded pipes, we assess suitability for no-dig drain relining (CIPP). Relining repairs the pipe internally without excavation — particularly valuable in London where excavation is disruptive and expensive.
Rat Barrier Investigation
CCTV identifies rat runs in London drains — cracks, displaced joints, and unsealed inspection chambers provide entry points. We inspect the drain, identify ingress points, and install one-way rat flaps to prevent re-entry.
No-dig repair in SW15
Drain relining after the survey
If the CCTV survey reveals cracked, displaced, or root-intruded pipes, we assess suitability for no-dig drain relining using CIPP (cured-in-place pipe) technology. A flexible liner is inserted into the damaged pipe and inflated against the pipe wall, then cured to form a new structural pipe within the old one. The repaired section is guaranteed and restores the pipe to full structural integrity without excavation.
No-dig relining is particularly valuable in London where excavation in tight back gardens, under patios, or beneath driveways and extensions is expensive and disruptive. The CCTV survey report provides the evidence required to specify the correct liner size and length, and confirms that the surrounding pipe wall has sufficient strength to support relining.
Drain ownership in SW15
Who is responsible for the drain?
Private drains serving only your property are your responsibility to maintain and repair. Shared sewers serving two or more properties were adopted by water companies under the 2011 transfer, but private lateral drains connecting your property to the adopted sewer remain your responsibility.
Understanding drain ownership before committing to repair work prevents disputes and ensures costs are allocated correctly. The CCTV survey report identifies the precise location of any defect within the drain run, making it straightforward to determine whether the repair falls within private drain ownership or within the adopted sewer network maintained by the water company.
