Professional CCTV drain surveys for residential properties and commercial sites across London. We inspect the drainage, identify defects and provide detailed reports and site plans.
A CCTV drain survey provides a detailed picture of the pipework beneath a property, allowing our engineers to identify serious defects and establish how the drainage system is laid out.
As part of our drainage services in London, we carry out CCTV drain surveys at residential and commercial properties for a range of reasons, including pre-purchase surveys, build-over and extension projects, rodent investigations, recurring drain problems and suspected subsidence.
Our surveys can identify the condition and type of drainage, including whether a drain carries foul water, surface water or combined flows. We also determine whether individual runs are private or shared, which is important when establishing who may be responsible for repairs.

From purchasing a property to investigating recurring drainage problems, there are many reasons to commission a CCTV drain survey in London. The right survey can help identify defects, establish the condition of the drainage and provide evidence for planning repairs or building works.
Buying a new home in London? A CCTV drain survey can reveal hidden drainage defects before you complete the purchase.
Planning building works? A drain survey can establish the location, condition and depth of drains near the proposed development.
Damaged drains and defective connections can provide entry routes for rats. A drain survey can help identify potential entry points.
Damaged or leaking drains can contribute to ground movement. A CCTV drain survey can identify possible causes of subsidence.
Repeated blockages in London properties may indicate hidden defects. A drain survey can help establish any underlying cause.
We carry out high-pressure jetting and CCTV drain inspections for property management companies and businesses across London.
Our CCTV drain surveys provide a detailed assessment of the condition of the underground drainage at properties across London.
Whether you're buying a new home, planning an extension or build-over, investigating rodent issues, concerned about subsidence, or experiencing recurring drainage problems, a CCTV drain survey can establish the condition of the drainage system and identify any defects.
Following the inspection, you will receive a detailed CCTV drain survey report and a site plan showing the inspected pipe routes and direction of flow. The report identifies whether drains are foul, surface water or combined, and whether individual runs are private or shared.
For build-over drain surveys, we also record the depth and location, providing information to support potential build-over agreements.
Where drainage defects are identified, we can recommend appropriate drain repairs and provide a quotation for any remedial works.

Many London terraced properties have drainage running close to the areas where homeowners want to extend. This is particularly common with rear and side-return extensions, creating large, open-plan kitchens.
Before building work begins, it is important to establish where the drains run, their condition and depth. A CCTV drain survey can help identify existing defects and provide all the information required.
Our build-over drain surveys include a detailed CCTV inspection and report. We also take measurements to establish drain depths at relevant points and distances from the building or boundary.
The accompanying drainage site plan records the inspected pipe routes, depths, pipe sizes and materials, direction of flow, and whether individual drains are private or public.
Our reports can support applications for build-over agreements, including those submitted to Thames Water, London's local water and sewerage authority, subject to the relevant authority's requirements.

From pre-purchase inspections to commercial drainage investigations, our engineers carry out CCTV drain surveys across London. Here are some examples of the types of work we undertake.
A CCTV drain survey of a semi-detached house for a prospective homebuyer to assess the condition of the underground drainage before purchasing the property. The drain inspection included a detailed report, drainage site plan and recommendations.
The customer needed to apply for a build-over agreement with Thames Water before they could build an extension. We inspected the existing pipework and recorded drainage routes, depths and locations of the drains in relation to the planned building works.
A homeowner had been advised by a pest control company to get a CCTV drain survey following concerns about rats entering the property. We inspected the underground drainage for damaged pipework, defective connections and potential entry points.
A terraced property was showing evidence of subsidence and the homeowner asked us to carry out a CCTV drain survey to investigate whether defects in the drainage system could be the cause of any ground movement. The CCTV survey report detailed all defects found.
We were working overnight carrying out a descale and CCTV drain survey at One Canada Square for the vertical stack pipes within the building. We supplied a comprehensive survey report with images and footage to show that the pipework was clear.
We were asked by a property management company to carry out a CCTV drain survey at an apartment block as they were having repeated issues with smells and slow running drains. The CCTV survey report identified the cause of the problems, which we rectified.
Answers to common questions about CCTV drain surveys, pre-purchase inspections, build-over agreements and drainage investigations across London.
The cost of a CCTV drain survey depends on the type of survey, whether the property is residential or commercial, and the amount of drainage to be inspected. Location and out-of-hours requirements can also affect pricing.
Our CCTV drain surveys cover residential and commercial properties across London and include an inspection of accessible underground drainage, a detailed condition report, drainage site plan, findings and recommendations.
Reports identify manhole depths, direction of flow, pipe diameters, pipe materials, any defects found, whether individual runs carry foul water, surface water or combined drainage, and whether drains are private or shared. CCTV footage can also be provided on request.
Buying a property in London is a big investment. A pre-purchase CCTV drain survey can identify hidden drainage problems before you commit to buying. It can reveal damaged pipes, displaced joints, root intrusion and other defects that may not be apparent during a normal property viewing or building survey.
If you're planning an extension within 3 metres of existing drainage, a CCTV drain survey may be required by Thames Water or the relevant sewerage undertaker. This is particularly relevant to extensions on London's terraced and semi-detached properties where drainage may run beneath or close to the proposed building works.
Our build-over CCTV surveys record the condition, layout, location and depth of the drainage, including whether drains are private or shared, providing the information typically required to support a build-over agreement application.
Rats can enter London properties through damaged underground drains, defective connections and redundant pipework, particularly where older drainage systems have deteriorated.
A CCTV drain survey can help identify these potential entry routes. If drainage defects are found, we can recommend appropriate repairs.
Leaking, cracked or collapsed underground drains can allow wastewater to escape into the surrounding soil, washing away fine particles or softening the ground. Over time, this can cause ground movement and potentially affect a building's foundations.
For London homeowners investigating suspected subsidence, a CCTV drain survey can identify damaged pipework and drainage defects that may be contributing to the problem, helping establish whether drainage repairs are required.
The time required depends on the size of the property, the number of drainage runs, access to the manholes and the condition of the pipework. A standard domestic CCTV drain survey may take just 1–2 hours, while larger commercial surveys can take considerably longer.
Yes. We regularly undertake CCTV drainage investigations for commercial premises, including industrial units, takeaway outlets, retail parks, hotels and apartment blocks throughout London. We use specialist crawler cameras to inspect larger-diameter pipework and can provide drainage site plans in CAD format where required.
If you have a specific drainage problem at your London property and don't require a full written report, we also offer a quick-look CCTV drain inspection. Our engineer can use a specialist drain camera to investigate the problem, show you the footage on site and explain any defects identified.
This is a simpler, lower-cost option for customers who want to understand what's happening inside their drains without commissioning a full drainage survey.
A quick-look inspection does not include the detailed written report, drainage site plan or formal documentation provided with our full CCTV drain surveys. It may therefore be unsuitable for pre-purchase investigations, build-over agreements or insurance purposes.
