CCTV Drain Surveys in London

CCTV Drain Surveys



As CCTV drain surveys are a necessity to see what is going on in the underground pipework, our dedicated surveying teams carry out dozens of investigations each week. With Drainsmart’s CCTV drain survey in London, we include a full written report complete with a summary of our findings and recommendations to return the system to a free-flowing and watertight condition if needed, as well as a detailed computerised drainage layout diagram showing the positions of manholes and gullies, etc. Our plans are well received across a number of professional trades, especially when compared to our competitors' hand-drawn versions which we have found on many occasions do not reflect the actual building or configuration of the system - you can see an example of what you can expect to receive from us here. We will also provide a copy of the video recording if requested.

Our charge for a CCTV camera inspection of all of the accessible underground drainage at a domestic property is £230.00 plus VAT which allows for 3 manholes, or £245.00 plus VAT for our Architect Package which includes superimposing the drainage layout onto supplied General Arrangement (GA) plans. Most standard size properties have 1 or 2 manholes and we allow time to inspect a 3rd however any extra chambers found will be charged at an additional £60.00 plus VAT per manhole.

We are also able to inspect larger sites such as blocks of flats and housing estates, schools, churches and commercial premises which are usually based on a day rate – please feel free to contact us for more information.




CCTV drain surveys allow us to look into the drainage system with a small portable camera unit with no disruption to the ground providing there is adequate access, making this the best way to identify problems. This is watched live on site by our experienced engineers and their notes are compiled into a full detailed report by our office team and signed off by a survey manager with a summary explaining the findings and any concerns as shown on our sample page.

If there is not sufficient access to the drainage, e.g. a manhole or rodding access point, a small localised excavation or a cut into above ground external pipework may be required to gain entry and we will reinstate the pipework and the surface area upon completion. This will be a last resort as we have TrapJumper cameras which have been designed to bypass gully and WC rest bends however there is the odd occasion it is not successful as it is dependent on the angle of the bends.

"Very professional and a quick turnaround time on the report. Thanks guys."

When was the last time you thought about your drainage system? Maybe never up until now. The good news is that this is not uncommon. Many customers call Drainsmart because they suspect something is happening with their drains, maybe an odour appearing, slow draining water, damp walls or cracks in the building or rat activity all of which require investigating to decide the best course of remedial action. They are also necessary to obtain information for extensions and Build Over Agreements, regular monitoring for insurance purposes following a claim especially relating to subsidence, or ascertaining the condition of the system for a Home Buyers survey (see below). We also are called out to advise on how to protect the private drainage system from vermin infestation and sealing any points they may be using to escape from.

Unfortunately, there is no way of ascertaining the extent of any issues underground without a prior CCTV drain survey in London and as each drainage system and the level of damage discovered is completely different, we are unable to give an estimated cost of any necessary repairs until we have the information this will obtain.

"Quick and efficient service by Drainsmart. Would recommend."

The video footage captured during our CCTV camera inspections can be saved onto a DVD or USB hard drive and/or sent electronically after it has been analysed upon closer inspection. A report will then be issued demonstrating a schedule of remedial works should any defects be discovered together with a computerised drawing showing the drainage layout.

If you are considering or currently in the process of buying a new home, you should always consider a Home Buyers drain survey. These surveys will inspect the drainage system and make sure there are no current or potential issues with the pipework. If you disregard a Home Buyers survey and there are pre-existing issues, you may find it hard to negotiate with an insurer or the previous homeowner, meaning you may be liable for the damages to your property. A Home Buyer drain survey can locate and identify drainage issues from small blockages to extensive problems.

"I chose Drain Smart based on being registered with he National Association of Drainage Contractors and online reviews, and I feel I made the right decision. The team were really polite, helpful, honest and went the extra mile to help me resolve my problem. They showed me what they were doing, what they had found (thankfully nothing) and ways forward (useful practical day-to-day advice about my drains). They were so thorough on the day that I was able to plan my next steps there and then. The final CCTV report came super quick and is really helpful. Overall, I was very pleased by the service on offer."

We can schedule your appointments over the phone or by email and are happy to liaise with any agents to arrange access if needed. As we have many crews on the road and with a CCTV camera inspection of a standard size domestic property taking around an hour to complete, we can usually attend within 24-48 hours to carry out the investigation.

What to expect when having a CCTV drain survey in London

You can book a time for our team to visit your property by getting in touch, either via telephone, email or the contact page.

Our engineers will arrive on time at your property and will inspect your drains using our CCTV camera equipment, using access points such as manholes.

Our engineers will examine the footage, looking for any issues such as blockages, infestations, or fractures in the pipework.

We will make recommendations based on what we find - which you can choose to proceed with if you wish.

We will present you with a report of the findings and computerised drawing showing the layout of the accessible system.

  • What are CCTV Drain Surveys?
    A CCTV Drain Survey or CCTV Camera Inspection involves a small portable camera unit being inserted into the drainage system which allows us to see inside the underground pipework and report on our findings. There are many reasons for investigations and we tailor our reports to each individual property. Find out more about CCTV Drain Surveys.
  • Are your computerised drawings to scale?
    Our drawings are not to scale and are for indicative purposes only however we can superimpose the drainage layout onto supplied architect GA plans for more accurate reading. Dependant on the access available, it is not always possible to determine the route or configuration of the drainage system and an assumption may be made based on our findings but this can be confirmed with electronic sonde tracing.
  • Do you provide the depth of the pipework?
    The survey does not include invert levels back to a datum but we will provide you with the invert depth of each chamber in millimetres which you could add to your levelling survey.
  • Do Drainsmart provide drain cleaning services?
    If so, how long does a blockage clearance or high pressure water jetting take? Unfortunately we cannot put a time frame on this as it is all dependant on the level and type of deposits found. A standard domestic blockage can usually be cleared within one hour but we cannot guarantee this and will not be able to know until we have the jetting hoses in the system and start moving the deposits. Find out more about this here.
  • I require drain repairing, can you help? How much do repairs cost?
    As each drainage system and the extent of damage which dictates the schedule of remedial works is completely different, this could drastically vary. Once we have carried out a CCTV camera inspection, we will provide you with a quotation for the remedial works but until further information has been obtained we will not provide a ball park figure. Learn more about drain repairs.
  • How long do your repair works take to complete?
    Again, this is dependant on the level of damage that was discovered and the remedial works that are instructed which could vary from a couple of hours to a couple of weeks. Where possible, we will try to send multiple crews specialising in different aspects of the trade to try to keep time on site to a minimum but this is not always practical.
  • Can you work on Thames Water sewers?
    Following the “Transfer of Sewers” Act in 2011, private contractors are not permitted to work on any Local Water Authority’s drains without their full permission, excluding CCTV surveys. It is common for these assets to run through your property and even if you are willing to pay for the necessary repairs, any contractor found to carry out work to these sections will be heavily fined and therefore we will not proceed without confirmation of their written consent.
  • Who do Drainsmart provide drainage services in London for?
    We work with numerous professional trades on a regular basis as well as schools, local councils and other authorities. See more on our Area pages.

A recent CCTV camera inspection by Drainsmart Ltd

A CCTV camera inspection of the underground drainage system at a property we visited revealed this earthenware pipe is severely fractured and it will be allowing the loss of water into the surrounding ground. As you can see in the video recording from the drainage survey, the fractures are over a long length of the drain and the extent of the water loss could contribute to damp or structural movement.


Although the damage is severe and needs to be addressed, this drain could be repaired by structural soft felt lining if there is adequate access to work from. If the access to the drainage system is insufficient, at least one excavation would be necessary to gain access to the underground pipework and we would be able to install structural soft felt liners from this point. 


Structural soft felt lining would be the better choice over structural patch lining as one sleeve would be able to repair the length of the drain instead of a high number of patches in precut lengths and is therefore more cost-efficient.


The client of this particular project did ask if it would be more beneficial to replace the whole length of pipework however as this drain runs under the house, the works would be very disruptive and the costs significantly higher. As structural soft felt liners and structural patch liners have a life expectancy exceeding 50 years, we would always recommend the installation of these over the replacement of drains wherever possible.


You will also see that there is a loose piece of broken pipework being pushed along the drain. This will be restricting the free flow of waste and could cause an overflowing blockage. We recommend removing this using a Picote Mechanical Grabber followed by high-pressure water jetting to flush through the remaining debris deposits.

Comments from Drainsmart customers

Below are some of the drain repairs reviews we have had from Drainsmart customers.

"This was an urgent short notice request to complete and report on a CCTV drain survey in connection with a property purchase in Wimbledon following on from a Building Surveyor's recommendation. Drainsmart could not have been more understanding and helpful throughout. They fitted the survey at short notice, completed it with minimal disruption for the current property owner and sent me a high quality (and - important for a lay person - readily digestible) report on the same day which enabled us to exchange contracts the following week. We will now do the work recommended."

Jan G., CCTV Drain Survey in London Customer

"Drainsmart had perfect customer service. They were efficient, polite and when things didn’t quite go to plan (an equipment failure totally out of their control) they dealt with it in the perfect way. They got in touch, rebooked at my convenience and expedited the report free of charge. I love companies with customer service like this. I will always recommend you Drainsmart for my experience! Thanks!!"
