Your checklist

Work through the list in order. Hide the notes when you know what to do.

  1. Shut off the water

    Your own stopcock first; the riser through the emergency service. You need to know where it is before, not during.

    The first minute decides the scale of the damage more than anything afterwards: water arrives faster than any investigation.

  2. Cut the power to the flooded areas

    Water and electricity together are dangerous. Switch it off at the consumer unit rather than unplugging with wet hands.

  3. Move devices, documents and valuables

    Out of the affected area and off the floor. Rescuing is easier than restoring, and you have minutes rather than hours.

  4. Call the emergency service and log the reference

    The time of the call, the reference number, what you were told. It is the first document and it fixes the timing.

  5. Tell the neighbours below

    They see the consequences before you do, and their flat is part of the damage. A calm warning saves weeks of argument.

  6. Find the source of the leak

    From above, from your flat, from the riser or from an appliance. If it is from above and nobody is home, that is the emergency service's job.

  7. Photograph and film everything, with the date

    Ceiling, walls, floor, furniture, appliances, stains. In a week the traces are gone and the money conversation is not.

    Filming in the first hour is the only proof of scale: a dried wall looks almost normal.

  8. Get the formal damage report drawn up

    The responsible organisation records the damage. Insist that everything is listed, including what appears later: damp, swelling, marks.

  9. Notify the insurer within the deadline

    If you have property or liability cover. Notification deadlines are usually short and stated in the policy.

  10. Talk to the neighbours in facts, not accusations

    Most floods are accidental. A calm conversation ends in compensation more often than months of correspondence.

  11. Do not sign off an amount immediately

    Some damage appears weeks later: swelling, mould, peeling. Assess the damage after drying.

  12. Start drying immediately

    Ventilation, a dehumidifier, removing soaked finishes. Mould starts within days, and that is a different job.

  13. Have the electrics checked before switching on

    Flooded wiring and appliances only go back on after a professional check. That is safety, not electronics.

  14. Note what would prevent a repeat

    Know where the valves are, replace hoses and connections on schedule, fit leak protection, do not run appliances unattended.

The first minutes are about water and electricity, not about blame

When water is coming in, the order is the same regardless of whose fault it is: shut the water off, cut the power to the affected areas, rescue what can be rescued, and only then work out where it came from and who pays. Conversations with neighbours and the building management do not stop water.

The second half is evidence. In a day there is less to see, and in a week nothing at all. That is why photographing and calling the responsible organisation happen immediately rather than after everything dries.

First actions

Step Why
Shut off the water Your stopcock is yours; the riser is the emergency service’s
Cut the power to flooded areas Water and electricity together are dangerous
Move devices and valuables out Rescuing beats restoring
Tell the neighbours below They see the consequences before you do
Call the emergency service And record the reference number and time

If it is coming from above, go up. If nobody is home, call the emergency service: entering a flat without its owner is their procedure, not yours.

Recording the damage

Photograph everything: ceiling, walls, floor, furniture, appliances, stains, swollen flooring, and the water still coming in if it is. Dated photos and video are the basis of every later conversation about money.

The formal damage report is drawn up by the responsible organisation; procedures and deadlines vary, but the principle is the same: the sooner and the more detailed, the better. Insist that the report lists all damage, including what will “appear later” — damp in the joints, swelling, ceiling marks.

Talking to the neighbours

A calm tone saves months. Most floods are accidental, and people are willing to compensate as long as the conversation is about facts rather than accusations. Still, record the agreements in writing — even with good neighbours.

Do not sign anything agreeing an amount before you know the extent: some damage appears weeks later.

Drying and consequences

Water must be removed and the space dried quickly: mould starts within days, and within a week come smells and damage to the substrate. Ventilation, dehumidifiers and removing soaked finishes work better than hoping it dries by itself.

Have the electrics checked before switching anything on: flooded wiring and appliances go back into use only after a professional has looked at them.

When the situation is under control

The water is off, power is cut where needed, the emergency call is logged, everything is photographed and filmed, the report is drawn up, the neighbours are informed, the insurer is notified, drying is under way, and money decisions wait until the damage is assessed.

Frequently asked questions

What should I do first if my flat is flooded?

Shut off the water, cut the power to the affected areas, move devices and valuables, call the emergency service and log the reference, and warn the neighbours below. Working out the cause and photographing everything comes right after that, not instead of it.
