What is a CCTV drain survey?
A CCTV drain survey is a structured camera inspection of the inside of an underground drainage system. A self-righting colour camera is pushed or driven along the pipe from a manhole, rodding eye or gulley, recording high-resolution video while a trained operator observes condition in real time. Every defect, deposit, lateral connection and structural feature is logged on the spot under the WRc Manual of Sewer Condition Classification (MSCC5) and the European coding standard BS EN 13508-2.
The output is two things: the raw video on USB or download link, and a written PDF report that lists every coded observation, severity-rated 1 to 5, with chainage (distance from the start point), still photographs, a sonde-traced route plan for mainline jobs and a written summary of recommended works. It is the only drainage inspection format accepted by Thames Water for adoption and build-over consent, by every major UK insurer for claim authorisation and by Building Control for new connections.
The cameras we run on London surveys are Pearpoint flexiprobe P340, Mini-Cam Solopro+ and full-size Wincan-controlled tractor crawlers for runs over 150mm. Sonde frequencies of 33kHz and 512Hz allow surface tracing through up to 2m of clay or concrete cover, which is essential for build-over evidence and for any extension that crosses a drain run.
When you need a CCTV drain survey in London
Four scenarios make up nearly all the CCTV survey work across London — and each one has a different reporting deliverable.
- Pre-purchase home buyer survey — done between offer and exchange. Output is a written WRc-coded report with photographs and recommended remedials, suitable for negotiation and for sharing with your solicitor and conveyancing surveyor. Typically £280–£420.
- Insurance claim documentation — done after a flood, foul backup, subsidence event or escape of water claim. Output is a WRc-coded report invoiced directly to the loss adjuster where authorised. £220–£380 typical.
- Diagnostic survey for recurring blockage or slow drainage — done when the line keeps blocking or smells of foul gas. Output is video footage and a fixed-price remedial quote. £140–£220 typical, often combined with a clearance jet.
- Build-over consent / Section 104 adoption — done either side of an extension that crosses a public sewer, or before a new drainage network is adopted by Thames Water. Output is BS EN 13508-2 coded video with sonde route plan, formatted to Thames Water's submission requirements. £420–£750.
- Commercial planned maintenance — done on restaurants, retail and offices on a 6 or 12-month cycle, often paired with high-pressure jetting under BS 7903. Output is a comparative report year-on-year tracking degradation. Quoted by site.
How the survey works — step by step
- 1. Booking and access (5 min) — call 0207 046 1363 with the property type, the reason for the survey and the access situation. We confirm a fixed price on the call. For pre-purchase work we co-ordinate access via the vendor or estate agent.
- 2. On-site setup (15 min) — locate manholes, rodding eyes and external gullies. Lift covers, take baseline photographs of chamber condition and confirm the run direction with a quick flow check.
- 3. Pre-clean if required (0–30 min) — if the line is heavily silted we run a quick flush with the jetter to clear sediment so the camera reads cleanly. This is included in the survey fee on standard jobs.
- 4. Camera run and live observation (30–90 min) — push the camera through the line at controlled speed, calling out and recording every observation under WRc MSCC5 and BS EN 13508-2. Sonde-trace the route at surface for mainline jobs.
- 5. Report write-up (24–48 hr) — observations transferred to PDF report, photographs extracted, route plan finalised, severity ratings reviewed by a second operator and the report emailed to the client (or loss adjuster) with the raw video as a download link.
CCTV drain survey cost London — 2026 prices
Pricing is fixed before we attend. The number that matters is what deliverable you need — video only, full WRc report, insurance-grade report or pre-purchase report. The price difference reflects the report write-up time, not the on-site time.

What we check on every CCTV drain survey
The survey methodology is consistent whether it's a domestic line under a Victorian terrace or a 300m mainline under a new-build estate. Every observation goes against the same WRc code table.
- Internal pipe condition along the full surveyed length, recorded to BS EN 13508-2
- Cracks, fractures and pipe deformation graded with WRc structural codes
- Root intrusion classified by ingress type (mass roots, fine roots, tap root)
- Open joints, displaced joints and lateral connection condition
- Scale, encrustation, fat/grease and silt deposits with percentage cross-section loss
- Hydraulic flow observation — standing water, partial blockage, surcharge evidence
- Lateral connection identification, including illegal misconnections to surface-water
- Pipe material identification — vitrified clay, pitch-fibre, cast-iron, UPVC, HDPE
- Inversion and gradient observation with sonde-traced run on mainline jobs
- Manhole condition — benching, chambers, step irons, cover and frame
- Backdrop chambers, interceptor traps and rodding eyes
- Surface-water vs foul-water separation and any cross-connection
Standards we report against
Reports without a recognised coding standard are routinely rejected by insurers and water companies. Every survey we issue is coded against the standards below — these are the references your loss adjuster or solicitor will recognise on first reading.
WRc Manual of Sewer Condition Classification (MSCC5)
The Water Research Centre's MSCC5 is the UK industry standard for grading drain and sewer defects from CCTV footage. Every observation in our reports is coded against MSCC5 categories — structural, service and construction — with severity ratings 1 to 5. Insurers, councils and water companies all read MSCC5 reports without further explanation.
BS EN 13508-2:2003+A1:2011
The European standard for the visual inspection coding of drains and sewers. BS EN 13508-2 sits underneath the WRc MSCC5 codes and ensures observations are repeatable across operators and survey companies. Reports we issue for adoption with Thames Water, Section 104 agreements or local authority highways drainage are coded to BS EN 13508-2 by default.
BS 7903:2020 Guide to selection and use of cleaning methods for drains and sewers
Where we recommend remedial cleaning after a CCTV survey — high-pressure jetting, root-cutting, descaling — the recommendation is made against BS 7903. This keeps cleaning specification, nozzle choice and working pressures within accepted limits and protects fragile pitch-fibre and old vitrified clay runs from over-jetting.
Sewerage Sector Guidance (SSG) and the Building Regulations Approved Document H
For build-over consent, drainage adoption (Section 104) and self-lay applications we follow Sewerage Sector Guidance and Approved Document H. CCTV evidence accompanies build-over applications to Thames Water and the pre/post-build re-survey is the most common reason a build-over consent is granted at first submission.
Worked examples — recent London surveys
Real jobs from the last 12 months, anonymised. The pattern repeats: clear coded observation on site, fixed-price remedial quote, no surprises for the client.
Victorian terrace, SE15 — recurrent blockage
3-bed Peckham terrace blocking every 6 weeks. Standard CCTV survey from the rear gulley revealed a displaced clay joint at 6.4m with a major root mass (MSCC5 RI-B, severity 4). Quote issued for patch lining and root cutting — £680 fixed, completed 4 days later. Re-survey confirmed clear.
Pre-purchase, NW3 — £1.6m Hampstead flat
Home buyer drain survey ahead of completion. CCTV identified a hidden lateral run under the basement extension that was not on the title plan. Buyer used the report to negotiate £4,800 off the asking price for future relining works. Total survey cost: £340.
Insurance claim, E14 — kitchen flood
Tenant flat in Canary Wharf flooded by foul backup. WRc-coded report issued to Aviva within 24 hours showed a collapsed pitch-fibre lateral at 11m. Insurer accepted the claim under the accidental damage clause — full reinstatement covered including no-dig repair.
Commercial restaurant, W1 — Westminster grease blockage
Soho restaurant with repeat kitchen drain blockages and an environmental health complaint. Full system survey identified a partially seized grease trap and 60% cross-section loss from FOG (fat, oil, grease) buildup in the underground run. Survey package included a planned-jetting schedule and a re-survey at 6 months.
Section 104 adoption, IG11 — new-build block
Pre-adoption survey on a 24-unit Barking development. Tractor-camera mainline survey at 140m, sonde traced and exported to PDF for Thames Water. Two minor defects flagged at handover and remediated by the developer before adoption certificate issued.
Build-over consent, SW18 — Wandsworth side return
Loft and side-return extension over a Thames Water-mapped public sewer. Pre-build CCTV showed the existing sewer in serviceable condition. Post-build re-survey confirmed no construction damage. Build-over consent issued by Thames Water at first submission.
