Leak Detection in Tower Hamlets
Tower Hamlets residents in postcodes E1–E4 deal with Thames Water's hard-water supply, which causes pinhole corrosion in older copper pipes — a leading cause of hidden leaks in Victorian and Edwardian properties. Separate sewer systems across Tower Hamlets also mean surface-water escape can go unnoticed until structural damage appears. Leak detection work in Tower Hamlets focuses on finding water loss before it damages walls, floors and utilities.
Tower Hamlets leak detection uses thermal imaging and pressure testing to find pinhole corrosion in copper pipes, common in Victorian and Edwardian properties supplied by hard-water Thames Water. Early detection stops structural damage and high water bills.
Drainage in Tower Hamlets — what local engineers know
Thames Water supplies hard water to Tower Hamlets, and the postcode zones E1–E4 see recurring issues with pinhole corrosion in copper pipework. Tower Hamlets Council's water-efficiency drive has made leak detection a priority; undetected leaks can inflate bills by 30% or more. The borough's separate sewer infrastructure (surface and foul drains run independently) means that leaks in external pipes may flow into the wrong system, masking water loss. Victorian terraces and Edwardian mansion blocks dominate the area, and their original cast-iron and copper supply lines are particularly vulnerable to corrosion in hard-water zones.
- Hard water supply causes limescale accumulation in boilers, radiators and soil pipe joints — powerflush and descaling demand is high across Tower Hamlets
- Separate sewer system across most of Tower Hamlets: 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 Tower Hamlets 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 Tower Hamlets?
In Tower Hamlets, 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 Tower Hamlets.
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 Tower Hamlets affects where these boundaries typically fall, and our local engineers know the E1, E2, E3 networks well enough to identify ownership quickly.

However, 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. Request your free quote and we'll confirm the price and your engineer's ETA in the callback.
