What to do if…
you suddenly have no running water in your home

Short answer

First, check whether it’s just your home (stopcock/inside plumbing) or a wider supply interruption (neighbours/water company). Then contact the right party quickly: your water company for network issues, or your landlord/plumber if it’s internal.

Do not do these things

  • Don’t assume it’s a regional outage without checking your stopcock/inside stop valve first.
  • Don’t keep turning taps on full and walking away (you can miss the moment supply returns and cause overflow somewhere).
  • Don’t drink water from unsafe sources (for example, heating systems/radiators/boilers).
  • Don’t try to force a jammed stopcock/valve with excessive force if you’re not confident (it can snap and cause a leak).
  • Don’t delay telling your landlord/letting agent if you rent—waiting can make damage and responsibility disputes worse.

What to do now

  1. Check the “is it just me?” basics (2 minutes).

    • Turn on the cold kitchen tap (often the mains-fed tap).
    • Ask a neighbour in the same building/street if they also have no water or very low pressure.

  2. Check your internal stop valve/stopcock is open.

    • Locate the inside stop valve/stopcock (often under the kitchen sink or where the supply enters).
    • Make sure it hasn’t been knocked partially shut. If you’re unsure or it feels stuck, stop and move to Step 5.

  3. If you’re in a flat or shared building, check for shared controls.

    • Some buildings have a communal shutoff or a management-controlled valve. If neighbours are affected, contact the building manager/caretaker/management company.

  4. If neighbours are affected, treat it as a water company issue.

    • Check your water company’s service updates for “no water/low pressure” incidents.
    • If you can’t find clear info, call the water company to report “no supply” and ask:
      • whether there is a known incident,
      • what they want you to do right now,
      • whether there is any drinking-water notice you must follow (for example, boil water advice).

  5. If it seems limited to your home, treat it as internal plumbing.

    • If you rent: report it to your landlord/letting agent immediately (in writing if possible) and ask what emergency repair route they want you to use.
    • If you own: contact an emergency plumber if you can’t restore supply by checking obvious valves and the issue is urgent (for example, no toilet use possible for the household).

  6. If the supply is out for a while, ask about alternative water supplies.

    • Ask your water company what replacement water is being provided (for example, bottled water, bowsers, or standpipes) and where/when to collect it.
    • If anyone in the home needs extra support, ask about the Priority Services Register (PSR) and what help they can provide during interruptions.

  7. Make safe, minimal arrangements for drinking and hygiene.

    • Use bottled water (or safe stored water) for drinking, brushing teeth, and preparing food.
    • Prioritise hand hygiene: use alcohol hand gel if you can’t wash with soap and running water.
    • For toilets: if you have safe non-drinking water (for example, stored water), you can often keep toilet flushing going by adding water carefully—go slowly to avoid overflow.

  8. If you’re on a private supply (well/spring) rather than mains.

    • Treat it as an on-site fault and contact a qualified local engineer.
    • If you’re unsure about water safety when it returns, your local council environmental health/private water supplies team (where available) can typically advise on next steps.

What can wait

  • You don’t need to diagnose the exact cause immediately—focus on confirming whether it’s network vs internal and getting the right party involved.
  • You don’t need to deep-clean appliances or flush systems right now; wait until supply is stable and you’ve checked any official notices.
  • You don’t need to pursue complaints/compensation in the moment—log times and facts first.

Important reassurance

It’s common for this to be a straightforward cause (a closed stopcock, a local burst main, planned works you missed, or a temporary pressure drop). Your job right now is simply to reduce risk (safe drinking water and hygiene) and get the problem routed to the correct responder.

Scope note

These are first steps to stabilise the situation and avoid damage or illness. Once you have basic water access (or clear updates), you can handle follow-up tasks like complaints, insurance questions, or longer outages.
