Specialist survey
CCTV drain survey cost when buying a house
A CCTV drain survey sends a camera through underground drains to identify cracks, collapse, roots, blockages, displaced joints and hidden repair liabilities that a normal house survey cannot see.
Typical buyer budget: about GBP150-GBP500 for a domestic CCTV drain survey, with higher costs for large plots, poor access or complex shared drainage.

Run a free previewWhen to book it
- The survey flags drainage issues or repeated blockage signs.
- The property is older with clay drains, mature trees or signs of ground movement.
- An extension may sit over or near a public sewer.
- You need repair evidence before renegotiating.
What it checks
- Pipe condition, cracks, root ingress, displaced joints, collapse and blockages.
- Drain route, access points and whether repair access is practical.
- Evidence for lining, excavation, clearance or further investigation.
- Whether defects are urgent or routine maintenance.
What it does not cover
- It does not replace the water and drainage conveyancing search.
- It does not certify legal ownership or responsibility for shared drains.
- It may not access every run if chambers are buried or blocked.
CCTV drain survey cost triggers
| Trigger | Inspection value | Next step |
|---|---|---|
| Older clay drains | Medium | CCTV if other risk signs exist. |
| Repeated blockages | High | CCTV before exchange. |
| Extension over drain | High | CCTV plus solicitor build-over check. |
| Simple blocked gully | Low | Clearance may be enough. |
Questions to ask before you pay
- Will I receive the video, plan and written defect schedule?
- Can you identify whether defects are urgent before exchange?
- Will the quote separate lining, excavation and clearance options?
- Are any runs inaccessible, and why?

Frequently asked questions
How much does a CCTV drain survey cost?

Should I get one before buying?
Consider one for older homes, blockage signs, trees, extensions over drains or surveyor recommendations.
Can the seller refuse a drain survey?
They can refuse access. If they do, you must decide whether the uncertainty is acceptable before exchange.
Does the drainage search check pipe condition?
No. It checks records and sewer context, not the physical condition of underground pipes.

Editorial owner: BiteRight Ltd, operator of MyPropertyScan. We review buyer guides against UK public property datasets, RICS survey wording, lender requirements, and common buyer questions.
Pages are updated when source coverage, property-risk guidance, survey cost assumptions, or product checks materially change. Methodology and dataset limitations are explained on the MyPropertyScan methodology page.
Sources used
We use UK public and specialist sources where they are available. Public datasets can be incomplete, delayed, or missing for some addresses. Treat them as a starting point, not as a replacement for professional advice.
Source standard: preference goes to official government datasets, statutory bodies, professional standards, and primary dataset publishers. We cite the source family on the page and explain coverage limits rather than filling gaps with unsupported estimates.
