What to do if…
your building water is being shut off for emergency repairs

Produced and maintained by PanicStation.org Published: Last reviewed: Editorial policy UK guide

Short answer

Confirm the shut-off time and where updates will come from, then store water now for drinking, handwashing, baby needs, medicines, pets, and toilet flushing. Avoid water-using appliances until supply is back and any official water-quality notice has been cleared.

Do not do these things

  • Don’t assume the water will be back exactly on time; plan for the stated window to change.
  • Don’t run washing machines, dishwashers, ice makers, water filters, or appliances that need a steady mains supply during the shut-off.
  • Don’t drink, cook with, or brush teeth with water if an official notice says to boil it or not use it.
  • Don’t use discoloured water for drinking unless your water company says it is safe.
  • Don’t forget anyone nearby who may struggle to collect or store water, including older people, disabled people, people with babies, and people with medical needs.

What to do now

  1. Verify the notice: Check the start time, expected duration, affected flats or floors, and whether the notice is from the water company, building management, landlord, or managing agent. Take a photo or screenshot.
  2. Find the update route: Check your water company’s service updates and your building’s noticeboard, app, concierge, managing agent, or landlord contact. Ask where bottled water, a bowser, or a standpipe would be placed if alternative water is provided.
  3. Store drinking water before the shut-off: Fill clean containers with lids where possible. Prioritise drinking, brushing teeth, medicines, baby formula, pets, and food that cannot wait.
  4. Store non-drinking water separately: Fill a washing-up bowl, bucket, or bath part-way for handwashing, basic cleaning, and toilet flushing. Keep it away from drinking-water containers and keep children away from open water.
  5. Set up one hygiene point: Put soap, hand sanitiser, wipes, a bowl of stored water, and a towel near the bathroom or kitchen so people are not searching once the taps stop.
  6. Reduce water demand now: Pause laundry, dishwashing, ice making, and filter use. Avoid turning on hot taps during the shut-off; if you are unsure about a boiler, cylinder, pump, or filter, follow the appliance instructions or building management’s instructions.
  7. Cover specific needs first: Store extra water for infants, pregnancy, illness, disability, medical equipment, carers, and pets. If someone in the home needs extra support during interruptions, tell the water company or building contact now, and ask about priority services for ongoing support.
  8. Check nearby support safely: Message a neighbour, carer, or building group if someone may not have seen the notice or may be unable to collect water. Keep it practical: share the shut-off time, update route, and water collection point if one is announced.
  9. When supply returns: Run the cold tap nearest your stopcock, if you can identify it, until the flow is steady and any discolouration clears. If the water remains cloudy, brown, has an unusual smell, or there is a boil-water or do-not-use notice, follow the water company’s instructions before using it for drinking or food.

What can wait

  • You do not need to decide about complaints, rent issues, or long emails now.
  • You do not need to buy special equipment if you can store water safely in clean containers.
  • You do not need to deep-clean pipes or appliances immediately when water returns; start with cold-tap flushing and follow official instructions.
  • You do not need to solve the whole building issue yourself; focus on safe water, hygiene, toilets, updates, and vulnerable people.

Important reassurance

A sudden water shut-off notice can feel alarming, especially in a block of flats, but the first steps are simple: store clean water, reduce appliance use, keep checking the official update route, and wait for clear water-quality instructions before drinking the supply again.

Scope note

These are first steps for the first hours of an urgent building water shut-off. If the outage becomes prolonged, someone has medical or care needs, or you receive a water-quality notice, follow your water company’s instructions and ask for specialist support where needed.

Important note

This is general information, not legal, medical, financial, therapeutic, or professional advice. Water-company duties and support arrangements can vary by supplier and by part of the UK, so check your own water company’s instructions for the current incident.
