A CCTV drain survey is one of the most useful diagnostic tools available to Swindon homeowners, buyers, and landlords — a small camera that shows you exactly what is happening inside your pipes instead of guessing. This guide covers what a CCTV drain survey is, when you need one, how long it takes, what it costs, and what the report you receive actually contains.
What is a CCTV drain survey?
A CCTV drain survey is a visual inspection of your drainage system using a small, waterproof camera fed through an existing access point on a flexible cable. The camera records high-definition footage of the pipe interior as it travels through the system, and the engineer watches it live, pausing and marking any defect found.
Nothing is dug up just to look. The camera goes in through a manhole, rodding eye, or drain opening that already exists, and everything it records is saved to form the basis of your written report.
When should you get a CCTV drain survey?
Get a CCTV drain survey before buying a property, if a drain keeps blocking despite clearing, if you have an unexplained sewage smell, or as planned maintenance on a commercial site. In Swindon, where pitch fibre and clay pipework from the 1960s–1980s is common, a survey is often the only way to know whether it is already failing.
Before buying a property
This is the single most valuable time to commission a survey. Standard homebuyer surveys and even full building surveys do not inspect underground drainage, so a pre-purchase CCTV survey is the only way to know what you are actually buying. In Swindon, pre-purchase surveys regularly find:
- Collapsed pitch fibre pipes in properties from the 1960s and 1970s
- Root intrusion in tree-lined streets near the Old Town and Highworth Road
- Joint displacement caused by clay shrinkage in central Swindon
- Incorrect connections and illegal drainage configurations in older properties
Recurring blockages
If your drains block repeatedly despite regular clearing, there is usually an underlying structural problem. A CCTV survey identifies whether the cause is scale and grease build-up, root ingress, pipe deformation, joint displacement, or a combination of factors.
Persistent smells
Unexplained sewage smells inside or outside a property usually indicate a cracked pipe, a collapsed section, or a displaced joint. A CCTV survey locates the problem precisely, avoiding unnecessary excavation.
Planned maintenance
Commercial property managers and landlords with multiple drainage systems often commission annual CCTV surveys as part of a planned maintenance programme. Catching problems early is consistently cheaper than emergency repairs.
How long does a CCTV drain survey take?
A CCTV drain survey typically takes 30 minutes to 4 hours depending on scope: a single-run inspection takes 30–60 minutes, a full domestic survey takes 45–90 minutes, a pre-purchase survey takes 1–2 hours plus a written report within 24 hours, and a commercial survey takes 2–4 hours.
| Survey type | Typical duration |
|---|---|
| Single-run inspection | 30–60 minutes |
| Full domestic survey | 45–90 minutes |
| Pre-purchase / homebuyer survey | 1–2 hours + report within 24 hours |
| Commercial survey | 2–4 hours |
What does a CCTV drain survey cost?
A CCTV drain survey in Swindon typically costs £90–£160 for a single-run inspection, £180–£320 for a full domestic survey, £220–£380 for a pre-purchase or homebuyer survey, and £300–£650 for a commercial network survey. See our CCTV drain survey cost guide for what drives the price within each band.
Against the cost of discovering a collapsed pipe after you have already moved in, a survey is extremely worthwhile — many Swindon buyers use survey results to negotiate a price reduction or walk away from a property with serious hidden defects.
What does the report contain?
Every CCTV drain survey report includes HD video of each pipe run, screenshots of any defects found, and a written condition grade for each section using the WRc defect coding system, the standard grading scale used across the UK drainage industry, plus a no-obligation quote for any repairs required.
Where defects are found, we can often carry out drain repairs and pipe relining on the same visit or at a follow-up appointment, using trenchless methods that avoid unnecessary excavation.
