CCTV Drain Survey Costs UK — What to Charge for a Drainage Survey in 2026

What Is a CCTV Drain Survey and When Is One Needed?

A CCTV drain survey involves feeding a waterproof camera — either a push rod or a crawler unit on larger pipes — through the drainage system to record the internal condition of the pipework. The footage is reviewed on a monitor at the time and, on a paid survey, written up into a report with condition grading and recommendations. It tells you and the customer what no amount of guesswork can: where the pipe is damaged, where it's blocked, where roots have got in, and whether the run has collapsed.

The common triggers for a survey are worth knowing because they tell you how the customer values the work — and a pre-purchase survey for a buyer about to spend £400,000 on a house is a very different sale to a landlord chasing a recurring blockage. The main reasons a survey gets booked:

• Pre-purchase / homebuyer survey: A buyer's conveyancer or surveyor recommends a drainage survey before exchange, particularly on older properties or where there's a history of subsidence in the area.
• Recurring blockages: A customer who has paid to clear the same blockage three times wants to know why it keeps happening — usually a partial collapse, displaced joint or root mass.
• Subsidence and cracking: Cracks in the property or sinking ground often trace back to a leaking or fractured drain washing out the surrounding soil. Insurers frequently require a survey as part of a subsidence claim.
• Building over or near a drain: Anyone planning an extension over or close to a drain needs to know its exact route, depth and condition before they get a build-over agreement from the water company.
• Insurance claims: Escape of water, subsidence and drainage claims almost always need documented survey evidence before an insurer will authorise repairs.
• Root ingress and collapse: Identifying tree-root intrusion or a collapsed section is something only a camera can confirm — and confirmation is what unlocks the repair quote.

CCTV Drain Survey Prices and What to Charge

The single biggest pricing mistake in this trade is treating every survey the same. A quick camera look down a single chamber to confirm a blockage is a different product to a documented, mapped homebuyer survey that a conveyancer will rely on. Charge accordingly. Here's how the main survey types break down with current UK price ranges.

Basic CCTV Survey (Verbal, No Report)

A basic survey is a camera inspection where you view the footage on site, tell the customer what you've found, and that's it — no formal written report. This is the right product when you're diagnosing a known problem for a homeowner who just wants to understand what's going on before deciding on a repair. It's quick, and it's where most reactive drainage work starts.

• Basic single-run camera inspection: £80–£150

Many operators waive this fee if the customer goes ahead with the repair, and that can be a fair commercial decision — but make the waiver explicit and conditional in writing, otherwise you'll find yourself surveying for free for customers who were never going to buy the repair.

Standard Domestic Survey With Written Report

A standard survey covers the accessible domestic drainage run and is written up into a formal report with footage, condition grading and recommendations. This is the bread-and-butter paid survey: a customer with recurring problems who wants documentation, or a landlord who needs evidence for a managing agent. The report is what justifies the step up in price from the basic inspection.

• Standard domestic survey with report: £150–£350

Price toward the top of this range where the run is long, where multiple chambers need to be lifted, or where the customer needs the report turned around quickly. The labour difference between this and a basic survey is small — the value is in the documentation, so don't undercharge for it.

Pre-Purchase / Homebuyer Drainage Survey

A pre-purchase survey is the highest-value domestic survey and should be priced as such. The buyer (or their conveyancer) is relying on your report to make a decision worth hundreds of thousands of pounds, so it needs to be thorough: full inspection of the accessible system, a drainage plan showing the route, identification of who owns each section, and clear recommendations. The professional standard is sometimes called a Level 2/3 or homebuyer drainage survey.

• Pre-purchase / homebuyer survey with full report and plan: £200–£400

These jobs carry more professional responsibility — your report may be quoted in a property negotiation or relied on after completion — so make sure your professional indemnity cover is in place and your report scope and limitations are stated clearly.

Larger, Commercial and Shared-Drain Surveys

Anything beyond a single domestic run costs more. Commercial premises, blocks of flats, long shared drainage runs and adopted sewer interfaces involve more pipe, more access points, larger-diameter pipework that may need a crawler camera rather than a push rod, and far more reporting. These are quoted individually, not off a price list.

• Larger / commercial / shared-drain surveys: £350–£900+ depending on length, diameter and reporting

Always do a quick desktop check or site visit before quoting commercial work — guessing the run length and chamber count is how you lose a day's money on a job you thought was a quick survey.

Add-Ons and Extras

High-Pressure Water Jetting

You can't survey a pipe you can't see down. If the run is full of silt, grease, scale or a partial blockage, it has to be jetted clean before the camera will produce usable footage. This is the most common reason a survey ends up costing more than the customer expected — and it's why you should always lift a chamber and check before quoting a flat survey price. Jetting is also frequently sold as the fix in its own right once the survey confirms a soft blockage.

• High-pressure water jetting to clear before survey: £100–£250

Drain Mapping and Plans

A drainage plan showing the route, depth and chamber positions of the system is a genuine value-add and a legitimate extra charge. It's essential for build-over applications, useful for any future repair, and expected on pre-purchase surveys. Produced from your survey footage and on-site measurements, a clear plan turns a report from a list of defects into something the customer can actually use.

• Report with drainage mapping / plan: £50–£150 extra

Locating With a Sonde

Most survey cameras carry a sonde — a transmitter in the camera head — which you trace from the surface with a locator wand to pinpoint the exact position and depth of a defect or the route of an unknown pipe. This is what lets you mark a collapse on the driveway with a tin of marker paint so the excavation goes straight to it rather than digging blind. Charge for it where it's needed.

• Locating / pinpointing with sonde: £50–£120 extra

What Affects the Price of a Survey

Two surveys on two different houses can legitimately differ by £200, and customers who've been quoted £90 by someone else need to understand why. The main factors are:

• Length and accessibility of the run: A short run off an accessible chamber is a quick job; a long run, or one accessed only through an internal stack or a buried chamber, takes far longer.
• Whether jetting or cleaning is needed first: A silted or partially blocked run has to be cleared before the camera can see anything — this is the single most common cost driver.
• Number of access points and chambers: More inspection chambers means more pipe to survey, more lids to lift, and more to report on.
• Depth and pipe diameter: Deep chambers and large-diameter pipe may need a crawler camera and more setup than a domestic push rod.
• Formal report vs verbal: Writing up footage, grading defects and producing a plan adds time and is the main difference between an £80 look and a £350 survey.
• Distance and call-out: Travel time and fuel to rural or out-of-area jobs has to be priced in.
• Homebuyer or insurance-grade documentation: Surveys that a third party will rely on demand more rigour, carry more professional responsibility, and are worth more.

What a Good Survey Report Includes

The report is the product on a paid survey — the customer is buying documentation, not just a camera being pushed down a pipe. A report that justifies your fee and protects you professionally should include:

• Recorded footage: The full video of each run surveyed, supplied to the customer along with still images of key defects.
• Condition grading: Defects classified consistently — many engineers reference a structural and service grading system so a customer or insurer can see severity at a glance.
• Clear recommendations: What needs doing, what can be monitored, and what is normal wear — not just a list of faults.
• A drainage plan: The route, chamber positions and approximate depths, especially on pre-purchase and build-over work.
• Ownership and responsibility: A note of which sections are the homeowner's private drain, which is a shared lateral drain, and which is public sewer.

That last point matters more than most engineers explain to customers. Since the 2011 private sewer transfer, most lateral drains and shared sewers that were previously private became the responsibility of the regional water company — the boundary is roughly where the drain leaves the property or joins a shared run. Defects on the public side are the water company's problem to fix, not the homeowner's, so flagging where the private drain ends can save your customer a repair bill entirely. Being the engineer who explains this clearly builds trust that wins the follow-on work where it genuinely is the customer's responsibility.

Turning a Survey Into Follow-On Repair Work

The survey fee is rarely where the money is. A survey that confirms a cracked joint, root ingress or a collapsed section is the gateway to repair work worth far more — and because you've got the footage, the customer has already accepted there's a problem. The common follow-on jobs are:

• Patch lining: A resin-impregnated patch cured in place over a cracked or open joint — a no-dig repair, typically £400–£900 per patch depending on access and diameter.
• Re-rounding and full lining: Reshaping a deformed pipe and installing a cured-in-place liner along a longer run, often £1,000–£3,000+ for a domestic run.
• Excavation and replacement: Digging down to a collapsed section and replacing the pipe — the most expensive option and the one where your sonde locating earns its keep by keeping the dig small.

Position the repair while you're on site with the footage on screen. Show the customer the defect, explain the no-dig options first (they're cheaper and less disruptive, which the customer will appreciate, and they protect your margin), and put the repair on a separate quote line from the survey. Where it's an insurance or subsidence matter, make clear your report supports their claim — that's often what gets the repair authorised and paid for by someone other than your customer.

Quoting Tips — What to Check Before You Price

Survey quotes go wrong when the engineer prices off a phone description rather than a quick look on site. Before you commit to a flat survey price, check the following:

• Lift a chamber first: Standing water or silt means the run needs jetting before you can survey it. Quote jetting separately or as a conditional extra so a blocked run doesn't eat your margin.
• Count the access points: Walk the property and find the chambers. More chambers and a longer run means more time — don't assume one quick look will cover it.
• Clarify the deliverable: Verbal, written report, or full homebuyer report with a plan? These are three different prices. Pin it down before you quote.
• Check who's paying and why: A buyer's pre-purchase survey, an insurance claim and a landlord's recurring-blockage diagnosis are all priced differently. Know the motivation.
• Confirm pipe size and depth: Large-diameter or deep runs may need a crawler camera rather than a push rod — make sure you're bringing the right kit.
• State your scope and limitations: Note any sections you couldn't access in writing, so you're not held responsible for defects in pipe you never saw.

Bundle the survey, any jetting and the repair quote into one clear document with separate lines. It shows the customer exactly what they're paying for, makes the follow-on repair feel like the obvious next step, and stops you being undercut by an operator who quoted a survey-only price and then hit the customer with surprise jetting charges.
