Which CCTV Survey Do You Need For Your London Property?
Don’t just guess—know. We offer specialised surveys tailored to your specific project requirements.
Standard Look-See CCTV Inspection: Best for recurring blockages, bad smells, and slow drains in London. Our engineers provide an immediate on-site diagnosis to identify roots or collapsed pipes. Price Start from £168 (Applies to single domestic properties with a non-shared drainage system only). Note: This entry-level service provides a visual diagnosis only and does not include a written technical report, video file, or drawing.
Homebuyer & Pre-Purchase Surveys: Essential for Property Buyers, Mortgage Lenders, and Solicitors. Standard building surveys miss underground drains—don’t risk inheriting a £5,000 repair bill. Our structural check produces a WRC-Approved Technical Report and HD Video Footage accepted by all UK lenders and insurers. Price Start from: £225 (Includes Full Data Pack and drainage drawings)
Build-Over & Drain Mapping: Extensions, Architects, and New Builds. Building near a public sewer? Authorities like Thames Water require a “Build-Over Agreement” for approval. We use Sonar Drain Tracing to map the exact depth and direction of your pipes, providing the certified pre- and post-construction maps required for building control sign-off.
Commercial & Industrial Surveys: Site Handovers, Schools, and Developers. We provide comprehensive asset mapping for large-scale sites in London. From large-diameter culverts to manhole inspections, our team delivers the detailed data and CAD drawings you need to ensure your site is fully compliant with environmental and safety regulations.

All our reports are produced to WRC (Water Research Council) MSCC5 Standards—the gold standard required by UK insurance companies.
Full Technical Report (PDF): A written log detailing pipe materials, flow direction, and diameters.
Defect Coding: All issues are graded from 1 (minor) to 5 (collapse) using official WRC codes.
High-Definition Video: A link to the full digital footage of your sewer inspection.
Still Images: High-res photos of key defects (cracks, roots, obstructions).
Site Plan: A schematic layout of your drainage system (essential for future works).
The Solution: A clear, fixed-price quotation for any necessary repairs (lining, patching, or excavation).
Our 4-Step Inspection Process
Access & Setup: Our qualified engineer arrives at your property or site in London, assesses the site, and identifies the safest access point (manhole or rodding eye) to insert the camera.
The Inspection: We insert a push-rod or crawler camera, navigating the entire length of the pipework while recording in HD.
Sonar Tracing: If we find a defect, we use above-ground sonar tools to pinpoint its exact location and depth—meaning we know exactly where to dig or patch without guesswork.
Report & Recommendations: You receive your full data pack and a no-obligation quote for repairs.

5 Tell-Tale Signs You Need a CCTV Drain Survey in London
Don’t wait for a complete drainage failure. If you are experiencing any of the following recurring issues, a professional CCTV drain inspection is the most cost-effective way to pinpoint the exact cause before it escalates into a costly structural repair:
Persistent Foul Smells: Unpleasant sewage odours lingering around your bathrooms, kitchens, or garden often point to a cracked pipe or a deep-rooted blockage that standard drain unblocking chemicals cannot reach.
Slow-Draining Sinks & Recurring Blockages: If your water takes ages to clear or your toilets repeatedly back up despite plunging, there is likely a larger underlying issue—such as a collapsed pipe, fatberg, or heavy tree root intrusion blocking the flow.
Unexplained Rodent Infestations: Rats in drains are a highly common issue across London’s older Victorian sewer network. Rats frequently use compromised clay pipes and broken drainage systems as a highway to enter properties. A camera survey is the only definitive way to find and seal their hidden entry points.
Damp Walls & Localised Flooding: Leaking underground drains allow wastewater to escape into the surrounding earth. This can lead to rising damp on your interior ground-floor walls or persistent, foul-smelling puddles and waterlogged patches on your driveway or lawn.
Subsidence and Structural Cracks: This is the most severe consequence of a broken drain. If a leaking pipe is left unchecked, the escaping water can slowly wash away the soil supporting your property’s foundations, leading to ground movement (subsidence) and visible cracks in your brickwork.

Why Choose Drain 247 For Your Drainage Surveys In London?
We Are Local: We aren’t a lead-generation site or a national franchise. We have been serving London since the early 90s. We know the local Victorian drainage systems and the heavy clay soil better than anyone. London’s aging sewer network is prone to collapse and root intrusion from tree-lined streets. Our crawler cameras are specifically calibrated to navigate these older, tighter clay pipe systems.
We Fix What We Find: We are full-service drainage experts. If our survey finds a break, we can fix it using “No-Dig” technology (structural lining) often on the same day, saving you the hassle of finding a second contractor.
Fully Accredited: We hold certifications from CHAS, Constructionline, and ISO. You are hiring vetted, insured, and qualified professionals.
What Our Customers Say
FAQs for Homebuyers & Residential Properties
1. How much does a CCTV drain survey cost in London?
Our pricing is fully transparent. A standard “Look & See” survey to diagnose recurring blockages or bad smells starts from £168 (ideal for single domestic properties). If you are buying a property, our comprehensive Homebuyer Survey, which includes a WRC-approved technical report and drainage maps, starts from £225. We provide fixed-price quotes with no hidden fees.
2. Why do mortgage lenders and insurance companies insist on a drain survey?
Standard building surveyors do not inspect underground drainage. If you purchase a property with collapsed pipes, severe root ingress, or subsidence issues, you could inherit repair bills exceeding £5,000. Lenders and insurers require our Homebuyer Survey because it produces a WRC MSCC5 standard report—the official industry benchmark—proving the structural integrity of the drainage system before you exchange contracts.
3. What are the common signs that I need a CCTV drain inspection?
You should book an inspection if you notice recurring issues such as slow-draining sinks, foul sewage smells indoors or outdoors, localized damp patches on walls, gurgling sounds from your plumbing, or unexplained rodent infestations. In London, rats often enter properties through compromised Victorian clay pipes. A camera survey is the only way to definitively find the source.
4. What is a Build-Over drain survey, and do I need one for my extension?
If you are planning an extension, a new build, or any structural work within 3 metres of a public sewer, local water authorities (like Thames Water) legally require a “Build-Over Agreement.” To get approval, you need a pre-construction and post-construction CCTV survey. We use sonar drain tracing to map the exact depth, condition, and direction of the pipes so your project can get Building Control sign-off without delays.
5. Can you map the drainage assets for large-scale commercial sites and new developments?
Yes. For developers, schools, and industrial site handovers, we provide comprehensive asset mapping. Our engineers can survey large-diameter culverts and complex manhole networks. We provide detailed CAD drawings and schematic layouts alongside the WRC-coded technical report, ensuring your site is fully compliant with environmental and safety regulations.
6. Can your crawler cameras navigate London’s older Victorian clay pipes?
Absolutely. We have been serving London since 1986 and understand the local infrastructure intimately. London’s aging sewer network, often laid in heavy clay soil, is highly prone to root intrusion and ground movement. Our crawler cameras are specifically calibrated to navigate these older, tighter clay pipe systems safely and effectively.
7. Will a commercial drainage survey cause disruption to my business operations?
We understand that businesses cannot afford downtime. Our CCTV drain surveys are highly efficient and non-invasive. We typically access the network via existing manholes or rodding eyes, meaning there is no excavation or major disruption required. If needed, we can schedule commercial audits during off-peak hours to ensure zero impact on your staff or customers.
8. What happens if the survey discovers a collapsed pipe or severe defect?
We are a full-service drainage company, meaning we fix what we find. If our survey identifies a structural defect, we will provide a clear, fixed-price quotation for the repair. Whenever possible, we use “No-Dig” technology (structural pipe lining or patching) to repair the pipe from the inside. This often allows us to fix the issue on the same day without digging up your car park, driveway, or garden.
9. How long does a standard CCTV drain survey take?
For a standard domestic property, a CCTV drain inspection usually takes between 1 to 2 hours. Larger commercial sites, complex build-over surveys, or full topographical drain mapping will take longer depending on the size of the network and the number of manholes that need to be accessed.
10. What exactly is included in your WRC-Approved Technical Report?
We provide a comprehensive, industry-standard data pack. This includes a PDF technical report detailing pipe materials and flow directions, official WRC defect coding (graded 1 to 5), high-definition video footage via a secure cloud link, high-resolution still images of any defects, and a schematic site plan of your drainage system.
