Everything you need to know about a CCTV Drain Survey

CCTV Drain Survey

What is a CCTV Drain Survey?

When you hear a gurgling sound coming from one of your drains, you know instantly that a problem is about to knock at your door. Most of the time, the problem is small in magnitude and can be handled with a little effort. But sometimes, it can be very difficult to find the source.

Blocked drains may be very aggravating, particularly if the reason is not discovered. It’s conceivable that you’ve already made unsuccessful efforts to fix your drain issues with normal methods. Not every drain issue can be found and repaired straight away. If the problem persists, a CCTV drain survey might be the way to go.

These surveys are developed to provide a comprehensive, in-depth inspection of your drainage network. Advanced Cameras are used to check up on your drains and transmit a live video back to the system. These surveys can be carried out for any size of drainage pipe.

What are the types of CCTV Drain Surveys?

Basic Survey:

A basic CCTV Survey is generally for exploration purposes only, The Surveyor will carry out the investigation and describe the issues.

Complete Survey

The complete survey includes the basic survey, but it also includes a complete report and CCTV footage as well. A complete drain survey generally includes:

Which Tools Are Used in a CCTV Drain Survey?

Waterproof Cameras:

These cameras are smaller in size with a torch mounted on them. They are connected to a system through a highly flexible pipe with a high tensile strength which houses the cables. These cameras, as per the requirement, are highly waterproof.

Access Rods

These rods are to push cameras down the drainage pipes. They are highly flexible and manoeuvre the camera through corners and curves.


They are specially designed rovers that can be remotely operated. They offer a good and fast visual of the sewer system.

Sonar System

Sonar system produces high-frequency (more than 20000Hz) sound waves that can map the sewer system and tell us where the blockage is.

Benefits of a CCTV Drain Survey

Time Saving

All of us want the drainage system’s issue to be sorted out quickly. You cannot simply disregard this problem as it grows to become intolerable. A CCTV drain survey assists in a quick evaluation of the primary reason and speeds up the repair work.


If you don’t know the magnitude of clogging, assuming the cause with limited data will not help. Using the Latest Cameras and Sonar, CCTV drain surveys provide highly accurate results. These surveys can tell the cause and the scale of the blockage, and you can take the necessary steps to resolve the problem.

Minimum Disruption

CCTV drain surveys cause a minimal degree of damage possible. Once the CCTV camera has located the problem, you can proceed to repair that specific area of the drain instead of a comprehensive excavation to find the issue.


Since CCTV surveys take less time to provide accurate results and need no repeated visits or big excavations, they can save a reasonable amount of money compared to conventional methods.

Best for new owners

If you want to buy a property, it will be a good idea to check the drainage system. A CTV drain survey can be of great help as it is time and cost-effective and provide precise results.

Cost of a CCTV Drain Survey

The cost of a CCTV drain survey can be effective by different factors, such as:

The complexity of the Drainage System:

It is an important factor to consider for the cost of a CCTV drain survey. As we know, drainage systems are different for different properties. Some properties may have a complex design which makes it difficult to navigate the CCTV camera inside the line. Furthermore, wider pipes require bigger cameras and crawlers, which ultimately affect the cost.

Length of the Drainage system:

The bigger the house is, the larger will be the drainage system, and it will take more time to carry out the survey. Hence, it will cost more to the landlord. The average cost for a CCTV survey for a larger house is £350 to £450.

Labour Charges:

If in case, you have to excavate to access the drainage system to eradicate the problem, it will cost you a little extra in the form of labour cost. This cost can range from £100 to £300 depending upon the quantity of the work.
