Quick Answer: What Is a CCTV Drain Survey?

A CCTV drain survey uses a small waterproof camera to inspect the inside of a drain or sewer. It helps identify blockages, damage, or ownership issues.

When you need one: - Before buying or selling a property - For insurance claims (evidence of damage) - To investigate recurring blockages - To resolve disputes over drain ownership

The survey produces a detailed report with video footage and recommendations.

Legislation and standards: - Building Regulations Part H (England & Wales) - Drainage design and installation requirements - Private Sewers Transfer Regulations 2011 - Defines ownership of shared drains - WRc Sewerage Rehabilitation Manual - Industry-standard defect coding (used in reports)

How CCTV Drain Surveys Work

The process:

1. A specialist contractor feeds a waterproof camera into the drain via an access point (manhole, gully, or rodding eye)

2. The camera travels through the pipework, capturing live video footage

3. The contractor identifies any defects such as cracks, root intrusion, collapsed sections, or blockages

4. A survey report is produced with images, video, and a recommended action plan

What the report includes: - Video footage of the entire inspection - Photos of any defects or damage - Defect coding (industry-standard classifications) - Recommendations for repairs - Drain mapping (optional)

Reports can be used for maintenance decisions, insurance claims, property transactions, or legal documentation.

When You Might Need One

Property purchase or sale: - Highly recommended before buying, especially older properties - Reveals hidden problems not visible in a standard homebuyer survey - Can save thousands in unexpected repair costs

Insurance claims: - Provides evidence of drain damage for claims - Documents the cause and extent of problems - Often required by insurers before approving repairs

Recurring blockages: - Identifies the root cause (literally, if tree roots are involved) - Helps determine if repair or replacement is needed - Prevents ongoing costly callouts

Disputes over ownership: - Clarifies whether a drain is private or shared - Provides evidence for discussions with neighbours or water companies - Can support legal claims if needed

Before building work: - Required for extensions near existing drainage - Helps plan connections to existing systems - Documents pre-existing condition

What Does a CCTV Drain Survey Cost?

Typical costs:

- Basic survey (camera inspection): £100–£150 - Full survey with report: £200–£350 - Survey with mapping: £300–£500+ - Emergency/same-day: Add 25–50%

Cost factors: - Length and complexity of drainage system - Access difficulties - Whether mapping/tracing is included - Location (London and South East tend to be higher) - Urgency of the work

Worth noting: The cost of a survey is usually far less than the cost of unexpected drainage repairs. A £250 survey could save you thousands in repair costs or prevent you buying a property with major drainage problems.
