CCTV Drain Survey Cost Guide 2026

CCTV drain surveys range from around £80 for a minimal residential inspection to over £1,500 for a comprehensive pre-purchase survey of a large property. The wide range reflects significant differences in what’s actually delivered. This guide explains what drives the cost, what you should expect at each price point, and how to evaluate whether a quote represents value.

Typical price ranges

Survey type	Typical cost range
Basic residential survey, single run, no report	£80–£130
Standard residential survey with written report	£150–£250
Pre-purchase full survey with WinCan report	£200–£350
Large residential or complex property	£300–£600
Commercial property, single drain system	£350–£800
Large commercial or industrial survey	£800–£2,000+

These figures are for the survey itself. If the pipes need to be jetted before the camera can pass (common for blocked or debris-filled drains), this may be quoted separately (£80–£200 for domestic jetting).

All prices should include VAT at 20%.

What’s included in a standard survey

Camera pass: HD camera (typically 60–200m range depending on equipment) is fed through the drain from an access point, usually an inspection chamber. The camera records footage continuously.

Condition assessment: The engineer identifies defects — cracks, displaced joints, root ingress, deformation, infiltration — and records their type, severity, and location (measured from the camera entry point).

Written report: A standard report includes a description of each pipe section inspected, the defects found, their severity grading (typically the WRc rating scale: D1–D5 for structural defects, F1–F5 for functional defects), and recommendations.

Footage: Most professional surveys deliver the recorded footage, either on a USB stick or via download link. This is important — if a defect is disputed later, the footage is the evidence.

What a WinCan report is and why it matters

WinCan is industry-standard drain survey software used by drainage contractors, local authorities, and water companies to produce consistent, structured condition reports. A WinCan-compliant report:

• Uses standardised defect codes (allowing any professional to interpret findings)
• Includes measured locations for every defect
• Produces a sorted defect schedule that identifies the most serious issues first
• Can be imported into local authority or water company systems if needed
• Is accepted by insurers, mortgage lenders, and legal professionals without translation

A contractor’s letter with verbal descriptions of “some cracking” is not the same as a WinCan report. For conveyancing, insurance, or commercial purposes, specify WinCan compliance before booking.

What affects the price

Length of pipe inspected: Most residential surveys quote up to a certain camera length (typically 30m). Additional length beyond this attracts a per-metre supplement. Longer properties, HMOs, or commercial premises with extensive underground drainage will cost more.

Pipe diameter: Larger pipes (commercial or industrial) require larger camera heads and are more expensive to survey.

Access: If there’s no accessible inspection chamber (common in older properties where chambers have been built over), a special access point may need to be created. This adds to the cost.

Pre-survey jetting: If the drain is blocked or heavily silted, the camera can’t pass until it’s cleared. Jetting is quoted separately if this is required.

Report format: A basic camera pass with no report or a verbal summary is at the low end. A full WinCan report with annotated footage, condition schedule, and remediation recommendations is at the high end — and the high end is worth the premium for anything other than a quick diagnostic check.

Urgency and location: Out-of-hours or expedited surveys, and surveys in London and the south east, typically attract a premium.

Questions to ask before booking

1. Does the survey include a written condition report, and in what format?
2. Is the footage included, and how will it be delivered?
3. Is the report WinCan-compliant?
4. What camera range is included in the base price, and what is the supplement per additional metre?
5. Is pre-survey jetting included or quoted separately?
6. What defect grading system do you use?
7. Is there an additional charge for the engineer to discuss findings with me?

A reputable surveyor answers all these questions before you book. Anyone who’s vague about report format or footage delivery should be questioned further.

What a cheap survey might be missing

Budget surveys (under £100) typically offer a camera pass from one access point with verbal findings or a basic summary document. They are appropriate for:

• A quick diagnostic pass when you know roughly what the problem is
• Confirming a single specific section of drain before a minor repair
• A basic condition check with no legal or insurance purpose

They are not appropriate for:

• Pre-purchase due diligence
• Insurance claims
• Planning drainage works
• Complying with a surveyor’s or solicitor’s recommendation

The cost difference between a basic survey and a full WinCan report is typically £80–£150. For the significant decisions — house purchase, insurance claim, major drainage works — this premium is immaterial compared to the consequences of acting on incomplete information.

After the survey: interpreting the results

Survey reports can be dense. Key things to look for:

• D-grades (structural defects): D4 and D5 indicate defects that require prompt attention. D1–D2 are noted but typically monitored rather than immediately remediated.
• Recommended actions: The report should include clear recommendations — is relining appropriate? Is excavation needed? Is the condition stable and monitor-only?
• Inspection limitations: Note what couldn’t be inspected (blocked sections, inaccessible branches) so you understand what is and isn’t covered.

If you’re unsure what the report means, ask the surveying contractor to walk you through the key findings. A good contractor will do this as part of the service.
