What to do if…
part of your ceiling collapses without warning

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

Short answer

Leave the affected room immediately and keep everyone and all pets away. Call 999 from a safe place if anyone is trapped or seriously injured, or if further collapse appears likely and people may be in danger.

Do not do these things

  • Do not stand beneath the damaged ceiling or return for belongings.
  • Do not touch hanging material, exposed wires, wet electrical fittings or loose debris.
  • Do not push, pull or tap the remaining ceiling to test it.
  • Do not climb a ladder or attempt an immediate repair.
  • Do not sweep, vacuum or bag unknown ceiling material.
  • Do not enter the area directly above the collapse until it has been assessed.
  • Do not operate electrical switches or use a flame if you smell gas.
  • Do not move someone with a possible serious head, neck or back injury unless they are in immediate danger.

What to do now

  1. Move everyone and all pets out of the affected room. Close the door only if you can reach it without approaching the damaged area.
  2. Move to a safer part of the property or leave the building if material is still falling, you hear repeated cracking, nearby walls or floors appear to be moving, or there is another sign of further collapse.
  3. Call 999 if anyone is trapped, unconscious, having difficulty breathing, bleeding heavily or otherwise seriously injured. Call 999 as well if part of the building may collapse and someone is at immediate risk.
  4. Prevent anyone from entering the affected room. Where you control the space, also keep people away from the area directly above it.
  5. If water is leaking and the main stopcock is safely accessible away from the damage, turn off the water supply.
  6. If wiring or electrical fittings are exposed, damaged or wet, do not touch them. Switch off the electricity at the consumer unit only if you can reach it safely without entering the damaged or wet area.
  7. If you smell gas or hear hissing, leave the property without operating electrical switches or using a flame. From outside, call 0800 111 999 in Great Britain or 0800 002 001 in Northern Ireland.
  8. Contact the person responsible for the property now. This may be your landlord, letting agent, housing provider, building manager or home insurer. State clearly that part of the ceiling has already collapsed and mention any water, exposed wiring, gas smell or continuing movement.
  9. Contact your local council’s dangerous structures, building control or building standards service if the damage may endanger another home, a shared area, a neighbouring property or the public.
  10. Leave the debris undisturbed. If the building was built or refurbished before 2000, asbestos-containing material may be present and should not be swept, vacuumed or handled before competent advice is obtained.
  11. Once you are safely away from the affected area, take photographs from a distance and note when the collapse happened, what you observed and who you contacted.

What can wait

You do not need to identify the cause, choose a repair method, decide who is responsible or resolve an insurance claim now. Cleaning, retrieving belongings, obtaining repair quotes and completing non-urgent paperwork can wait until a competent person has confirmed that the area is safe.

Important reassurance

A partial ceiling collapse does not necessarily mean the entire building will collapse. The safest response is still to keep clear because the remaining ceiling and any hidden water, electrical or structural damage need to be assessed directly.

Scope note

This guide covers immediate safety and contact steps only. Decisions about repairs, temporary accommodation and whether the property can be occupied may require help from the emergency services, your local council, a competent contractor, a chartered structural engineer, your landlord or your insurer.

Important note

This is general safety information, not a structural, electrical, plumbing, medical, insurance or legal assessment. Follow instructions from emergency services and qualified professionals who can inspect the property directly.
