Most drainage issues start small, a build-up of grease, a cracked pipe, or a few tree roots sneaking into a joint. But left unnoticed, these small problems can lead to serious damage, flooding, and expensive repairs. That’s where CCTV drain surveys come in.
These advanced inspections allow engineers to look deep inside your drains without any digging, helping homeowners, landlords, and businesses spot issues before they escalate. In this blog, we’ll explore how CCTV drain surveys work, when to get one, and why they’re one of the smartest investments for maintaining your property.

What Is a CCTV Drain Survey?
A CCTV drain survey involves inserting a high-definition camera into the drainage system. The camera sends a live video feed to a monitor, allowing trained engineers to identify:
• Cracks or collapsed pipes
• Tree root intrusion
• Blockages or build-ups
• Displaced joints
• Corrosion or structural damage
The technology used today is incredibly precise. United Drains uses professional-grade equipment that records the inspection and provides a full report, complete with footage, images, and recommendations.
How Does the Process Work?
Here’s what you can expect when booking a CCTV drain survey:
1. Initial Assessment – Engineers assess access points and the layout of your drainage system.
2. Camera Insertion – A waterproof camera attached to a flexible cable is inserted into the pipework.
3. Live Monitoring – Real-time footage reveals the internal condition of the drains.
4. Analysis & Reporting – Engineers review the recording, pinpointing problem areas.
5. Recommendations – A detailed report and cost estimate for any repairs are provided.
The process is clean, non-invasive, and often completed in under an hour for residential properties.
When Should You Get a Drain Survey?
CCTV surveys aren’t just for emergencies, they’re a valuable preventive measure. Consider booking one if you’re:
• Buying a new property – Ensure there are no hidden drainage problems before you commit.
• Experiencing slow drainage or foul smells – These are early signs of a blockage or structural issue.
• Managing commercial premises – Routine inspections help maintain compliance and reduce downtime.
• Planning building or extension work – Understanding the layout of existing drains prevents costly mistakes.
Many homebuyers now request CCTV surveys before finalising a purchase, and insurers often recommend them after flooding or repeated blockages.
The Benefits of CCTV Drain Surveys
CCTV drain surveys offer several key advantages:
1. Early Detection of Problems
Identifying damage early can prevent thousands of pounds in repair costs. For example, a minor root intrusion can be fixed easily if caught in time — but left untreated, it can cause a full pipe collapse.
2. No Guesswork
Rather than digging up your garden or driveway, engineers can pinpoint the exact location of a fault using the camera feed and tracking equipment.
3. Full Transparency
After the survey, you’ll receive a detailed report and video footage, so you know exactly what’s going on beneath your property.
4. Cost-Effective Maintenance
Routine inspections save money long-term by preventing emergencies that require immediate, more expensive repairs.
5. Peace of Mind
Knowing your drains are in good condition gives you reassurance, especially before buying or selling property.
How CCTV Technology Has Evolved
Modern CCTV drain cameras offer crystal-clear imagery and real-time analytics. Older systems only provided grainy visuals, but today’s high-definition cameras can identify even the smallest cracks or obstructions.
Many systems also use sonar mapping and remote-controlled crawlers, which can travel long distances through pipes of various diameters. This technology enables engineers to inspect complex commercial drainage systems with precision and minimal disruption.
Common Problems Found During Surveys
CCTV drain surveys frequently uncover hidden issues that traditional inspections would miss. Common findings include:
• Fat, oil, and grease build-up (especially from kitchens)
• Displaced or misaligned joints caused by ground movement
• Cracks and fractures in older clay or concrete pipes
• Root ingress from nearby trees
• Collapsed sections from age or vehicle pressure
When these problems are detected, United Drains can provide immediate solutions, from drain unblocking to drain repairs, ensuring minimal disruption to your property or business.
Why Businesses Should Prioritise Drain Surveys
Commercial properties often handle larger volumes of wastewater, so preventive maintenance is crucial. For restaurants, hotels, and factories, a blocked drain can mean lost revenue and potential hygiene breaches.

Regular commercial drain maintenance keeps systems compliant with health and safety standards, while reducing the risk of downtime.
The UK Health and Safety Executive (HSE) recommends routine inspections for any business managing waste or water systems, especially in sectors like hospitality, construction, and manufacturing.
The Environmental Impact
Well-maintained drains prevent pollution and flooding, protecting local ecosystems. When wastewater escapes through damaged pipes, it can contaminate soil and waterways.
By scheduling CCTV surveys and addressing damage early, property owners play a part in reducing environmental harm and supporting sustainable drainage management.
The Environment Agency regularly highlights how responsible drain management helps prevent watercourse pollution and flooding.
