Local knowledge
How Tower Hamlets properties leak
Tower Hamlets housing is dominated by high-rise apartments, warehouse conversions and Victorian terraces. Tower blocks around Canary Wharf run boosted risers and communal heat networks, leaks here need correlator kit and coordination with building management.
Knowing the local building stock matters: it tells us where the pipework usually runs, which materials to expect, and which detection method will get to the answer fastest, before we arrive.
Covered in Tower Hamlets
- Hidden leaks under floors and in walls
- Underground supply pipe leaks
- Central heating and boiler pressure loss
- Underfloor heating loop leaks
- Flat-to-flat leak origin investigations
- Trace & access reports for insurance claims
Three methods, one marked point
Acoustic survey
Ground microphones and correlators follow the sound of escaping water through floors and ground.
Thermal imaging
Infrared cameras reveal wet patches and buried heating runs through the floor surface.
Tracer gas
A safe hydrogen mix escapes through the exact failure point and rises to our surface detector.
What fails here
Common leak problems in Tower Hamlets
01
Boosted riser leaks in high-rise blocks
Tower Hamlets has more tall residential blocks than most London boroughs, and their cold and hot supplies run on pressure-boosted risers that sit well above normal mains pressure. A weeping joint or pinhole on a riser pushes water sideways into party walls and drops several floors before anyone upstairs notices. We trace these with acoustic correlators clamped to the riser, then coordinate isolation with building management so the whole stack is not shut off unnecessarily.
02
Slow losses on communal heat networks
Many newer developments run communal heat networks, with insulated flow and return pipes serving dozens of flats from a central plant. Buried runs in service voids and basements lose water slowly through corroded fittings, and the make-up valve masks it until pressure keeps dropping. We use thermal imaging and tracer gas to pin the loss to a specific run, so the managing agent repairs one section rather than excavating the whole corridor.
03
Push-fit failures hidden in voids
Fast-build flats across the borough rely heavily on push-fit plastic fittings buried in stud walls, ceiling voids and riser cupboards. A fitting that was never fully engaged can hold for years, then release under pressure and soak the plasterboard below. Because the water tracks along joists, the damp patch rarely sits under the actual fault. Moisture mapping and acoustic tracing let us open one panel rather than stripping a whole ceiling.
04
Stacked-bathroom leaks passing between flats
Bathrooms are stacked vertically in apartment blocks to share soil stacks and supplies, so a failed shower tray seal or waste connection two floors up appears as a stain on someone else's ceiling. Establishing which flat is the source needs controlled testing and access agreements between leaseholders. We produce a clear trace and access report that names the source flat, which freeholders and managing agents use to direct the repair and settle the insurance claim.
What the data says about Tower Hamlets
How leaks behave in Tower Hamlets, and why
Tower Hamlets is one of the most flatted places in the country
80.7% of Tower Hamlets homes are in a purpose-built block, more than double the London median of 36.6% and 2nd of 331 local authorities nationally. Water leaving a pipe on an upper floor does not surface on that floor. It runs along a joist, drops through a service void, and shows up in a different flat entirely.
At this density the question is almost never "where is the water" but "whose pipe is it", and that argument is settled by a survey rather than by whoever complains loudest. We isolate and pressure test before a ceiling is opened, because here the cost of a wrong guess lands on a neighbour.
Communal heating changes what a pressure drop means
8.3% of households here run on a district or communal heat network, more than double the London median of 2.3% and 5th of 331. On a communal system a falling pressure reading is not your boiler, and often there is no boiler in the flat to look at. The loss can be anywhere on a shared circuit, including outside your own front door.
Isolating your section from the riser answers that inside the first hour, which is worth knowing before anyone lifts a floor you may not be responsible for.
When the repair is your landlord's to arrange
35.9% of Tower Hamlets households are social rented, well above the London median of 21% and 4th of 331. Where that applies the repair is usually the landlord's or the housing association's, and what moves it up a queue is a written location and cause. A report naming the pipe, the position and the evidence is much harder to defer than a phone call about a damp patch.
Who supplies the water in Tower Hamlets
Water here is supplied by Thames Water, so a high-usage letter, the four-week repair window and any leak allowance claim all run through them. The pipe from the boundary stop tap into the property is yours, including the length under a garden or driveway.

Leak detection in Tower Hamlets, FAQs
How quickly can you attend a leak in Tower Hamlets?
Same-day appointments are usually available in Tower Hamlets, and next-day almost always. If water is actively escaping, tell us when you book, live leaks are prioritised and we can talk you through isolating the supply while an engineer travels.
Do you charge if you can’t find the leak?
No. Every detection visit in Tower Hamlets is covered by our no find, no fee promise: if we attend a confirmed live leak and cannot locate it, the detection fee is waived.
Can you provide a report for my insurer?
Yes, trace and access reports documenting the cause, precise origin and affected areas are available for every Tower Hamlets detection visit, typically within 48 hours. They are structured the way UK loss adjusters expect.
Which parts of Tower Hamlets do you cover?
All of it, including Canary Wharf, Bethnal Green, Bow, Wapping, Whitechapel, Stepney. We cover every London borough and out to the M25, so coverage never depends on which side of a postcode line you live.
A leak is affecting several flats in my Canary Wharf tower. How do you trace it across floors?
On boosted risers and communal pipework, water often appears floors below the actual fault. We use acoustic correlation along the riser to narrow the source before anything is opened, and coordinate with concierge or the managing agent for access to the affected flats. You get an insurer-ready report identifying the location, which helps settle who is responsible under the lease.
Do you produce reports managing agents can use for communal leak claims?
Yes. At a fixed hourly rate, usually £320–£640 in total, our non-invasive trace produces a written report with findings and images suitable for managing agents, block insurers and leaseholders. That matters in Tower Hamlets blocks where a leak in shared risers or a heat network affects multiple demises and responsibility needs documenting before any repair or finishes are disturbed.
