Drain Survey Cost

How Much Does a Drain Survey Cost?

You can expect to pay between £90 and £500 for a CCTV drain survey, depending on the type of survey needed. If the job is relatively straightforward, some surveyors will have a fixed cost, whereas in other instances they may need to visit the property to generate a quote.

Are CCTV Drain Surveys Expensive?

The standard cost of a drain camera inspection usually falls between £90 and £500, with the average price being £250 for a standard-size house inspection and mapping of all the drains. If you only need a basic drain survey to identify a specific problem, costs will be towards the lower end of the scale, although prices are generally higher in London and the South East.

Closed-circuit television (CCTV) drainage surveys were once costly, but the price of this technology has reduced considerably in recent years. Be wary of expensive survey prices — even a large drainage system should not cost more than a few hundred pounds.

What Are CCTV Drain Surveys Used For?

CCTV drain surveys are used to determine the condition of your existing pipework and identify any blockages. They're often used to diagnose drains that keep blocking even after being cleaned, and will return CCTV footage, a diagnostic report, pipe mapping, and repair recommendations where needed.

As a general rule, a standard CCTV drain survey cost won't include any physical drain cleaning, unblocking, or repair work unless specified within the quote.

Labour Costs and Timescales

As with many jobs, the cost and time required can vary depending on the size and complexity of the situation — particularly when it comes to any work required after the survey itself.

Labour Fees for a CCTV Drain Survey

A basic CCTV drain survey typically costs around £90, while a full CCTV drain survey may cost up to £350.

The exact cost will depend on the property, and in some cases a professional may need to visit before providing a quote. In other cases, a price can be given over the phone or by email. Location and access also play a role, with labour fees generally higher in London and the South East.

Timescale for a CCTV Drain Survey

The time it takes to complete a CCTV drain survey depends on the length and complexity of the home's drainage system. Larger properties tend to have more extensive drainage, which takes engineers longer to cover thoroughly.

Factors That Impact CCTV Drain Survey Costs

A CCTV drain survey will typically cost anywhere between £100 and £300, depending on several key factors. The size of the property and its drainage system is usually the primary driver of cost, but there are other variables to be aware of.

• Pre-Survey Cleaning and Jetting — If the drain or surrounding area is severely blocked or overflowing, a surveyor may not be able to get a clear picture of the wider situation. In these instances, you may be charged for cleaning and jetting separately, typically around £100 to £150.
• Property Type — Different property types require different drainage specifications. Homes with more intricate layouts, such as winding dips and sharp corners, may need a larger camera to inspect wider pipes, which can increase the overall cost.
• Length of Drain — Larger properties have more extensive drainage systems, which take longer for a camera to inspect. The average CCTV inspection cost on a larger property is between £350 and £450, and can take up to 4 to 6 hours.
• Ease of Access — Not all drains are easily accessible. If ground needs to be excavated or the drain entrance located, this can add £100 to £300 in additional costs, as well as extra time to the overall job.
• Number of Access Points — Multiple manhole covers extend the time needed to complete the survey, as each one needs to be lifted and inspected along with the drainage below. More access points also increase the level of detail required in the report, which adds to the overall labour cost.
• Location of Property — Your location in the UK can make a difference to your CCTV drain survey costs. Tradespeople may charge above the national average in London and the South East due to a higher cost of living.
• Emergency CCTV Drain Survey — If you need a CCTV drain survey carried out at short notice or as an emergency, you may be charged an additional call-out fee.

Pre-Purchase Drain Survey Costs for Home Buyers

The average pre-purchase CCTV drain survey cost when buying a new home is around £250 to £350 for a standard property.

When buying a property, you'll typically need a full pre-purchase drain survey. This provides a comprehensive CCTV drain survey report that gives you peace of mind about the condition of the drainage system before you complete the property purchase.

A pre-purchase CCTV drain survey covers the full extent of the property's drainage system, including:

• Underground pipework and connections to the main sewer.
• Manhole condition and access points.
• Any defects, root ingress, collapsed pipes, or serious deterioration.
• Recommended remedial work and estimated repair costs.

Once completed, the drain survey report is typically shared with:

• Mortgage lenders — Your mortgage lender may require it before approving a mortgage on older or non-standard properties.
• Solicitors — As part of the conveyancing process.
• Insurance providers — Insurers may request it before issuing a drainage insurance policy.

Many lenders and insurers will recommend or require a CCTV drain survey prior to approving a mortgage or policy, particularly for older or non-standard properties. It's worth checking with your provider before proceeding.

If significant issues come to light during the pre-purchase CCTV drain survey, the drain survey report gives home buyers the evidence they need to renegotiate the purchase price or request that repairs be completed before contracts are exchanged.

Insurance claims relating to drainage problems are also easier to make when a pre-purchase CCTV drainage survey has been carried out, as it establishes a clear baseline for the condition of the system at the point you took ownership.

What's Involved in a CCTV Drain Survey?

Technically, you can carry out a basic drain inspection yourself, but it's not usually recommended. Professional CCTV drain surveyors arrive fully equipped with industrial-grade cameras, access rods, and remote-operated crawlers — equipment that most homeowners would need to buy or hire, and then learn to use before even getting started. Without the expertise to interpret the footage accurately, a DIY attempt can quickly become a waste of time and money.

Because of this, most homeowners choose to find and hire a qualified CCTV drain survey specialist. With MyJobQuote, you can get quotes from professional CCTV drain survey specialists near you — fast, free, and with no obligation to go ahead.

Here's a broad overview of what to expect when a professional carries out a CCTV drain survey:

Before the Survey

• Access Point Identification — The specialist will locate manholes and access points to establish entry into the drainage system.
• Equipment Setup — All necessary equipment is prepared on site, including waterproof CCTV cameras, access rods, and remote-operated crawlers.

During the Survey

• Camera Insertion — The CCTV camera is fed into the drainage system via access rods and pushed through the pipework.
• Live Footage Review — Footage is fed back in real time to the engineer, who monitors the condition of the drain as the camera travels through.
• Issue Identification — The engineer notes any problems identified — including blockages, cracked or collapsed pipes, root intrusion, corrosion, and signs of pest activity.

After the Survey

• Findings and Recommendations — The specialist reports what was found and advises on next steps. If repairs are required, they'll outline what's needed and may arrange a follow-up.
• CCTV Drain Survey Report — A full written report is produced, documenting pipe diameters, materials, invert levels, flow direction, and drain usage, alongside video footage, images, and a site plan of the manholes.

What Are the Main Causes of Drain Issues?

Drain problems can develop gradually or appear without warning. If you've recently moved into a property and want to check the condition of the drainage system, or you're experiencing recurring issues — such as slow-draining sinks, gurgling toilets, or persistent bad smells — it's worth understanding what may be causing them before they escalate.

Below are the most common causes of drain problems, and the signs to look out for.

• Persistent bad smells — Foul odours from drains, sinks, or outside manholes are one of the most common early warning signs. They're usually caused by a build-up of organic matter, grease, or waste somewhere in the system that a CCTV survey can quickly pinpoint.
• Slow drainage or water backing up — If water is draining noticeably slowly from sinks, baths, or showers, or you're hearing gurgling sounds after flushing, there's likely a partial or full blockage restricting flow somewhere in the pipework.
• Grease, fat, and oil build-up — FOG (fats, oils, and grease) poured down kitchen drains solidifies on the inside of pipes over time, gradually narrowing the bore until flow is restricted or blocked entirely. It's one of the most frequently identified issues on domestic CCTV surveys.
• Non-flushable items — Wet wipes, sanitary products, and other non-biodegradable items that are flushed accumulate in the pipework and can cause serious blockages. Unlike toilet paper, they don't break down and tend to catch on any existing rough patches or joint defects.
• Tree root intrusion — Tree roots naturally seek out moisture and will exploit even the smallest crack or open joint in underground pipework. Once inside, they expand and restrict flow. This is particularly common in older properties with clay pipes and in areas with mature trees nearby.
• Displaced or open joints — Ground movement, settlement, or general age can cause pipe joints to shift out of alignment. Even a small displacement creates a ledge where debris accumulates and can allow groundwater or soil to enter the system, leading to further deterioration.
• Pipe deterioration and corrosion — Older drainage systems — particularly those with cast iron, clay, or early plastic pipework — are vulnerable to corrosion, cracking, and general wear. Once the structural integrity of a pipe is compromised, collapse or leakage becomes a matter of time rather than if.
• Scale and deposit build-up — In hard water areas, mineral scale accumulates on the inside walls of pipes over time, progressively reducing the internal diameter and restricting flow. CCTV surveys can assess how severe the build-up is and whether descaling is needed.
• Rodent ingress — Rats can enter drainage systems through cracked pipes, displaced joints, or redundant drain connections. A CCTV survey can identify the exact entry points, allowing rat blockers or repairs to be targeted precisely rather than guessing.
• Bubbling around plugholes — Bubbles forming around a plughole as water drains away indicate that air is trapped in the system — a sign that flow is being obstructed somewhere. If this is happening across multiple fixtures, it points to a blockage or structural issue further along the drain rather than a localised problem.

What Can a CCTV Drain Survey Find?

A CCTV drain survey and report is designed to identify exactly what's happening inside your pipes and drainage system. Below is an overview of the most common findings.

Blockages

Tree roots and debris are a common cause of drain blockages, entering through cracks or fractures in the pipe's surface. Slow-flowing water is often the first indicator, as the obstruction restricts the passage of water through the system.

Cleaning and unclogging drains may be required immediately following the survey, typically costing around £100 and taking between 1 and 2 hours.

Collapsed Drains

Collapsed drains can be difficult to detect without a survey, and are often caused by repeated blockages, flooding, or ground movement. Signs include bad smells, slow-running water, damp patches, and structural damage around the affected area.

If a collapse is confirmed, a professional will typically need to excavate the ground before fixing or replacing the affected pipes.

Surface Water Issues

If the survey identifies a surface water drainage problem, you may need to install a soakaway drain beneath your driveway. This is a more involved job, typically taking 1 to 3 days and costing around £500 to £1,000 depending on the size of soakaway required.

Corrosion

Corrosion, rust, and general wear and tear will affect most drainage systems at some point. Metal pipes are particularly susceptible to chemical reactions and temperature fluctuations, which can restrict water flow and cause odours.

If your water is running slowly, colder than usual, or with a foul smell, it's worth getting your pipes inspected.

Drain Line Damage

If the survey reveals damage to your drain line, you'll need to arrange a repair. Drain line repairs are a significant job, typically costing around £850 and taking between 1 and 2 days to complete.

Animal Infestation

Drains can attract rodents and other pests, particularly during colder months when animals seek warmth and shelter. Animals can carry diseases including salmonella and tuberculosis, and their presence can cause physical damage to pipework over time.

If you suspect an infestation, contact pest control first. Once the area is clear, a CCTV drain survey can confirm whether any further damage has been caused to the drainage system.

Checklist: Hiring CCTV Drain Survey Specialists

• Do they have the correct qualifications? Make sure your surveyor has the correct qualifications including a completed CCTV drain surveying training such as the NADC Certified Drain Surveyor (CDS) course.
• Can they show evidence of past work? Confirm that your surveyor is fully authorised to complete a CCTV drain survey and report, and has completed jobs like this in the past. Ask for previous pictures and references from their former clients and jobs.
• Do they have positive reviews? Check for any recent feedback on their MyJobQuote profile and look for consistent ratings and comments on reliability, quality of work, and value for money.
• Do they have public liability insurance? This helps protect you in case of property damage or injury during the job. Ask to see proof before work starts.
• What is included in the quote? Some companies will clear minor blockages free of charge while carrying out the survey, whereas others will charge extra, so ensure when comparing quotes you are doing so on a like-for-like basis.
• Is waste removal included? Some surveyors include this in their quote, others don't. Always confirm whether disposal of debris or old pipework is covered.
