Most drain faults are out of sight. A CCTV drainage survey puts a camera through every run and records it. You see the problem and where it sits.
FS Group has surveyed London drains since 1998. A Look and See camera check starts from £130.00 + VAT, with no call-out fee.

I recently had a CCTV drainage performed by FS Drainage to satisfy Thames Waster Build Over Agreement required for a rear extension. The service was fantastic at a reasonable price and great advice provided by the engineer for future reference. I would not hesitate to use any their services again and highly recommend to anyone looking to have a CCTV drainage survey performed.
We had a drainage survey done for a house we are potentially looking to buy. The property had a man hole at the back of the house and our surveyor had recommended to check it to see if there are any cracks (as it could apparently be costly to fix this). Jordan from FS drainage came well equipped to do our CCTV drainage survey and very patiently explained how the drainage works and the current condition, which was very useful since we are first time buyers and had no idea how this works. He gave us quick quotes for potential works that needs to be done in the near future. FS also sent us a report shortly after the work was completed (within a couple of hours). Even booking for an appointment on short notice was very seamless with FS. Highly appreciate it and can’t recommend them enough!
I would without hesitation recommend FS drainage. Integrity and honesty are always a great trait for any company. This morning FS Drainage sent a drainage agent Mitch, who had both in spades. We had called them for a cctv report, Mitch took one look at it and said this is a main drain problem and if we can find the main drain ( which was no mean feat in our street ) he could maybe fix the problem. We went out to explore, this young man’s determination to help me was a real credit, not just to him but the company in general.For the price of our initial report our problem was fixed, I would like to add at this point two other companies who had been called for this problem did not rectify.
Very professional, fs drainage attended promptly and were excellent during inspection process . I would highly recommend. Guided us through the inspection explaining in detail as progressed. Very pleased and so much better than our insurers drainage company by far.
Absolutely brilliant service. Called at 10am and the team arrived by 1:15pm. Went above and beyond to get our drain unblocked, very detailed with the CCTV and explaining the issues with the drain. Very professional and personable. Highly recommended!
We have just had a drain survey done by your engineer Josh. He arrived on time, was very polite and incredibly helpful explaining and showing us everything as he did it and discussing possible options to achieve our requirements. Highly recommendable. Well done
Josh came today to screen my drains, he was great, really knows his job very well, he was so patient and helpful, It was an absolute pleasure. He did his job way and beyond !
I originally called out Thames Water for two badly blocked drainage gullies. The two Thames Water operatives were very unprofessional and lazy. After saying that they needed to find the main manhole drain, they gave up after 15 minutes of looking. They advised me to get a drainage company with camera equipment. Luckily FS Drainage were recommended to me by a family member and they turned up on site within an hour of Thames Water leaving. Josh from FS Drainage was very professional and curtious in comparison to Thames Water. Josh used the hi tec camera equipment to exam the drains and make a quick assessment. After a bit more exploration and digging, we were able to find the main manhole drain. It had been buried by shingle and earth. Josh did not hesitate to enter the drain and clear years of built up debris and tree root growth. You can see the issue on the attached video. I am so pleased that he persevered, despite the fact that it was raining heavily with a bit of lightning. If he had not cleared the debris then it would eventually have blocked the main sewer. The price was very reasonable and discussed as the job progressed. Gabriel from head office co-ordinated the job report, invoice etc very professionally and swiftly. The job report was delivered within hours of leaving site. It was very informative and professionally written. I would not hesitate to recommend FS Drainage.
Jordan came over to do a look and see with a camera down our soil pipe. Really good customer service, I'd be happy to recommend FS drainage to friends/family. All staff I've spoken to have been very helpful and friendly. Thank you!
On the day
Most homes take one to two hours on site. Larger buildings and long runs take longer.
Call or ask for a callback. Tell us why you need the survey, so the right kind is booked. Mention any deadline, such as an exchange date.
The engineer lifts the manholes, locates the rodding eyes and checks which way the water flows. Our blog explains what an inspection chamber is.
A camera cannot see past a blockage, so any blocked run is cleared first, at our unblocking rates. Then a self-lit camera records each run, with pipe size, material and distance.
Before leaving, the engineer explains the faults, what caused them and what fixing them would involve. The written report follows.





What the camera sees
The same six faults account for most of what we record. Knowing them helps you read your own report.
Victorian and Edwardian streets still drain through salt-glazed clay. It cracks with age, ground movement and the weight of parked cars.
When joints shift, they leave a lip that catches paper and grease. Many repeat blockages start at one displaced joint.
Roots find their way in through hairline gaps and then grow. Gardens with mature trees, and streets lined with planes, see this most.
Kitchen grease sets hard on the pipe wall and narrows it. Scale does the same in hard-water areas. Jetting usually clears both.
Terraces and converted flats often share one drain, and nobody has a plan of it. The survey shows whose section a fault is on.
A dip holds standing water and silt. A collapse stops flow entirely. Both show clearly on camera, with the distance from the chamber.

Send Thames Water the footage instead of paying for the repair yourself. The report says where the fault sits.
Drain ownership
A survey often ends with a fault on a pipe that is not yours to fix. The footage shows which side of the line it is on.
