No Water in London? Here's Why, and What to Check First
Total loss of water is either the network, the stopcock, or a freeze, and each has a different right answer.
Two minutes of checks usually says which, and saves a callout when it's the water company's problem, not yours.
No water at all in London: do this now, while you wait
- Ask a neighbourIf they're dry too, it's the network, check your water company's incident map and report it. No plumber required.
- Check both stopcocksThe internal one (make sure it hasn't been knocked closed) and the outside meter valve, water company work sometimes leaves them half-shut.
- In freezing weather, suspect a freezeCold water only, upstairs only, one bathroom only, partial loss patterns point at a frozen run, not the mains.
- If you hear water you can't see, stopcock offNo supply at the taps plus the sound of running water can mean the supply pipe has burst underground. Close the stopcock and call.
What causes no water at all in London
- 01Network outage or mains work
The water company's problem, and their compensation scheme, worth knowing about.
- 02Closed or failed stopcock
Stopcocks get knocked, seize half-open, or fail internally, the gate drops off old gate valves silently.
- 03Frozen supply pipe
The run from the boundary to the house freezes where it's shallow or exposed.
- 04Burst supply pipe
A soggy patch on the path or a hissing meter with dry taps, the leak is between the boundary and your kitchen.
Local conditions we work around
London runs on some of the hardest water in the country, roughly 280 to 320 ppm from the chalk that Thames Water draws on. Scale is the quiet cause behind a surprising share of the emergencies we attend: it narrows pipework, coats heat exchangers until a boiler overheats and locks out, and seizes the very stopcock you need at two in the morning. Add pipework that in much of the city dates to the Victorian or Edwardian build and was last touched in the 1960s, and the failures cluster in ways we can usually predict from the postcode before we arrive.
