How much does a CCTV drain survey cost in 2026? A standard CCTV drain survey costs £120-£350 in the UK, depending on the length of pipework inspected and whether a written report is included. A basic camera inspection of a single run starts from around £120, while a full pre-purchase survey of every accessible drain on a property, with a recorded video and engineer’s report, typically costs £200-£350. Prices include VAT from reputable firms.
At TrueFlow, CCTV drain surveys start from £120 including VAT, and we agree the exact price with you before any camera goes into the pipe.
What You’re Actually Paying For
A CCTV drain survey sends a waterproof camera through your drains to show, rather than guess, what is happening underground. The cost covers more than the camera time:
- The inspection itself. An engineer feeds a camera through each accessible run, watching a live feed and recording it.
- Locating equipment. A sonde transmitter on the camera head lets the engineer trace the exact line and depth of the pipe from the surface, which matters if repairs are ever needed.
- The report. For homebuyer and insurance work you should receive a written report with footage, defect locations, pipe material and sizes, and a recommendation. If a firm’s price seems low, check whether a report is included at all.
- Cleaning first, if needed. A camera cannot see through standing water or grease. If the drain is partially blocked, it may need jetting before the survey; combined jetting-and-survey visits (from £220 with us) cost less than booking the two separately.
CCTV Survey Costs by Situation
Recurring blockage investigation: £120-£200. One or two runs inspected to find why the same drain keeps backing up. This is the most common survey and the cheapest, because the area of interest is already known.
Pre-purchase homebuyer survey: £200-£350. Every accessible drain on the property inspected, with a full recorded report you can send to your solicitor or surveyor. Worth it on any house older than the 1970s, since a collapsed or root-damaged drain can cost thousands to excavate and is invisible to a standard building survey.
Insurance claim survey: £150-£300. When subsidence or water damage may be drain-related, insurers usually want CCTV evidence with a written report before approving works.
Build-over survey: £150-£300. If you are extending over or near a public sewer, the water company requires proof of the pipe’s condition before and sometimes after the build.
When a Survey Is Worth It (and When It Isn’t)
Pay for a survey when a drain blocks repeatedly, when you are buying an older property, when you can smell drains but find no obvious cause, or when a builder needs to know where pipes run before digging. One £120 survey that catches a failing clay joint early is cheap against a £1,500+ excavation later.
Skip the survey for a first-time blockage with an obvious cause. A one-off clog from wipes or fat just needs clearing, and any honest firm will tell you so. Costs for clearance work are covered in our drain unblocking price guide.
Questions to Ask Before You Book
Ask whether the price includes VAT, whether a written report and footage are included, how many metres or runs are covered, and whether jetting is extra if the pipe needs cleaning first. Fixed pricing agreed before work starts should be the norm; be wary of open-ended hourly rates for survey work.
CCTV Drain Survey Cost FAQs
How long does a CCTV drain survey take?
Most residential surveys take 1 to 2 hours. A single problem run can be inspected in under an hour, while a full pre-purchase survey of a larger property with several access points can take half a day.
Do I need a CCTV drain survey when buying a house?
It is not legally required, but a standard building survey does not look inside the drains. On homes built before the 1970s, where clay pipework and decades of ground movement are common, a £200-£350 drain survey can reveal defects that would cost far more to repair after completion, and the report can be used to renegotiate the price.
Will my home insurance pay for a drain survey?
If the survey is part of a valid claim, for example investigating subsidence or escape of water, insurers often cover it. A survey booked purely for peace of mind or a house purchase is not covered. Check your policy wording for drainage investigation cover.
Can a blocked drain be surveyed?
Not properly. The camera needs a reasonably clear pipe to see the walls and joints, so a blocked or heavily greased drain is usually jetted first. Combined visits keep the cost down, which is why we price jetting plus survey from £220 together.
