CCTV Survey in Barnet
Barnet's separate sewer system and Victorian clay drainage mean root ingress and blockages are common. We inspect with high-definition CCTV to diagnose blockages, assess pre-purchase property condition, and produce reports accepted by mortgage lenders and insurers across EN5, EN6, EN7 and EN8.
CCTV drain surveys in Barnet use colour high-definition cameras to inspect clay, salt-glazed and plastic pipes. Reports diagnose root ingress, blockages, and structural faults. Results are encoded in WinCan format and accepted by mortgage lenders and home insurers.
Drainage in Barnet — what local engineers know
Thames Water manages Barnet's water supply, but drainage infrastructure falls to Barnet Council. With 32% of properties built before 1920, salt-glazed clay pipes and lead-solder copper joints are routine findings. The separate sewer system means surface water drains are easily misconnected—kitchen waste, washing machines, and detergent spills poison what should be clean water. Grease, wipes and tree roots blocking clay sewers remain the leading cause of call-outs across Barnet.
- Hard water supply causes limescale accumulation in boilers, radiators and soil pipe joints — powerflush and descaling demand is high across Barnet
- Separate sewer system across most of Barnet: misconnections (e.g. washing machines plumbed into surface water drains) are a known local issue and can result in environmental enforcement action
- Ageing infrastructure in parts of Barnet means drain blockages from grease, wipes and root ingress remain the most common call-out reasons
- With 32% of properties built before 1920, salt-glazed clay drainage and lead-solder copper pipework are common — pipe collapse, root ingress and joint failure are recurring call-out drivers.

Who's responsible for drains in Barnet?
In Barnet, responsibility for a blocked or damaged drain depends on where the fault sits. As a homeowner you are responsible for the drains within your property boundary that serve only your home. Since the 2011 private sewer transfer, Thames Water is responsible for shared sewers and lateral drains beyond your boundary — even where they run under private land. Road gullies and highway drainage are maintained by Barnet.
This matters because it determines who pays. If our engineer's CCTV inspection shows the fault is in a shared sewer, we'll tell you — and you can report it to Thames Water rather than paying for the repair yourself. The separate sewer layout that dominates Barnet affects where these boundaries typically fall, and our local engineers know the EN5, EN6, EN7 networks well enough to identify ownership quickly.

Every Barnet job is quoted as a fixed price before work starts — what we quote is what you pay, with no call-out fee for providing the quote. The final price depends on access (an external inspection chamber is quicker than internal-only access), the pipe material and condition , and how established the blockage or fault is.
