A CCTV drain survey sends a camera through your drainage pipes to record their condition. It sounds straightforward — and it is — but the cost varies depending on what you need and how much of the system needs inspecting. This guide breaks down the types of survey, what you pay, and the scenarios where commissioning one is clearly the right call.
Types of CCTV Drain Survey and Their Costs
Diagnostic Survey (Single Drain)
Purpose: Find the cause of a specific problem — a recurring blockage, an unexplained wet patch, or slow drainage.
Typical cost in Manchester: £150–£250
What you get: Camera inspection of the problem drain from the nearest access point. HD footage. Written report identifying any defects or debris. Recommendation for any remedial work.
Pre-Purchase Survey
Purpose: Check the condition of all drainage at a property you’re considering buying.
Typical cost in Manchester: £200–£350
What you get: Full inspection of all accessible drainage runs — foul water and surface water. Manhole inspection. HD footage for you to keep. Detailed written report suitable for use in property negotiations or insurance purposes.
Full-System Survey (Larger Properties or Commercial)
Purpose: Map and assess an entire drainage system — common for HMOs, commercial premises, housing associations, or properties with complex drainage.
Typical cost: £300–£600+
What you get: Full drainage map, condition grading to Water Research Centre standards, written defect schedule, and video archive.
When Is a CCTV Survey Worth It?
Before Buying a Property
This is the single most cost-effective use of a drainage survey. A pre-purchase CCTV survey costing £200–£300 can:
- Reveal collapsed pipes requiring £3,000–£10,000 of excavation
- Identify tree root ingress that will worsen every year
- Uncover illegal connections that create legal liability
- Give you negotiating leverage to reduce the purchase price
Several of our Manchester customers have reduced their purchase price by thousands after survey results were presented to the seller. On any property purchase, a drain survey is cheap insurance.
Recurring Blockages With No Obvious Cause
If a drain blocks repeatedly despite being cleared professionally, there is usually a structural reason — a broken pipe, a belly in the line, or root ingress. Each unblocking treats the symptom; a CCTV survey finds the cause.
Without the survey, you’ll keep paying for unblocking indefinitely. With it, you can assess whether a one-off repair — pipe relining or a targeted excavation — solves the problem permanently.
Before Laying a New Extension or Driveway
Building over or near drainage requires understanding where the pipes are and their condition. Laying a concrete slab over a deteriorating pipe will make future repairs vastly more expensive. A survey before construction protects you and satisfies any planning or building control requirements.
Insurance Claims
Insurers increasingly require a CCTV survey report before authorising drainage repair claims. Having footage and a written report that clearly shows the cause and location of the defect speeds up the claims process and prevents disputes.
Foul Smells With No Visible Blockage
Drain odours that persist after clearing can indicate a cracked or offset pipe allowing gases to escape into the soil and permeate into the property. A camera survey locates the source.
What the Survey Doesn’t Do
A CCTV survey diagnoses — it doesn’t repair. The survey tells you what’s there; remedial work is a separate cost. We always quote for any follow-on work separately and you decide whether to proceed.
What to Ask For When Booking
Make sure the company provides:
- HD video footage you can keep — essential for insurance and negotiations
- A written report with defect descriptions and GPS or measured locations
- WRC condition grading if required for insurance or planning
- No-obligation repair quote if work is needed

Frequently Asked Questions
How long does a survey take?
A single-drain diagnostic survey typically takes 45–90 minutes. A full pre-purchase survey of a three-bedroom house usually takes 1.5–2.5 hours.
Can I watch the survey being carried out?
Yes — we welcome customers watching the inspection. Seeing the footage in real time helps you understand the report and ask questions on the spot.
Do I need to prepare anything?
Make sure all manholes and inspection chambers are accessible before we arrive. If any are buried under decking or locked outbuildings, let us know when you book so we can advise.
