Short answer

Keep people away from wet ceilings, walls and nearby electrics, then report the problem or contact a competent guttering or roofing contractor urgently. Do not climb a ladder or go onto the roof while conditions are wet, windy or slippery.

Do not do these things

Do not stand beneath a bulging, sagging, cracking or waterlogged ceiling.
Do not touch wet switches, sockets, light fittings, electrical equipment or the consumer unit.
Do not use a ladder or climb onto the roof in rain, strong wind or slippery conditions.
Do not lean out of a window to reach the gutter.
Do not drill, puncture or press a swollen ceiling or wall.
Do not place a bucket where you must remain beneath an unstable ceiling.
Do not assume that wiping, drying or repainting the wall has dealt with the source.
Do not make permanent alterations to a rented or shared building before contacting whoever is responsible for repairs.

What to do now

Move people, pets, furniture and valuable items away from the affected wall or ceiling. Close off the area if plaster is sagging, cracking, bulging or falling.
Check from a safe distance whether water is near a socket, switch, light fitting, consumer unit or electrical appliance. Do not touch anything in the wet area.
If you can reach the consumer unit without stepping into water or touching anything wet, switch off the electricity supply. Otherwise keep clear and contact a registered electrician for urgent advice.
Leave the affected area and call 999 if there is fire, smoke, sparking, a burning smell, a ceiling appears likely to collapse, or anyone is in immediate danger.
From ground level or another safe position, note where the gutter is overflowing. Look for an obvious blocked outlet, detached joint, sagging section or downpipe that is not carrying water, but do not try to reach it during bad weather.
Use buckets, towels or waterproof sheeting to contain indoor drips only where the ceiling appears stable and there is no electrical risk. Do not work directly beneath the leak.
Contact a competent guttering or roofing contractor and explain that rainwater is running down or entering the wall. Mention any ceiling movement, damaged masonry, electrical fittings or difficult access.
If you rent, report the problem promptly to your landlord, letting agent or housing provider using any emergency repair route provided. Send a written description and photographs, and keep a copy.
If the gutter serves a flat or shared building, contact the managing agent, freeholder, housing provider or other person responsible for the exterior.
Photograph or record the overflow and visible damage from a safe position. Note when it began and whether it happens only during rain.
Contact your buildings or contents insurer promptly if the building or belongings have been damaged. Follow its instructions before arranging non-emergency permanent work.
If water continues after the rain has stopped, the source may not be the gutter alone. Contact an appropriate contractor, such as a roofer or plumber, to identify it.

What can wait

You do not need to decide now whether plaster must be replaced, how the room will be redecorated or who will ultimately pay. Detailed drying, mould treatment, insurance estimates and permanent gutter improvements can wait until the area is safe and the source of the water has been controlled.

Important reassurance

An overflowing gutter does not by itself confirm serious structural damage. Keeping clear of unstable surfaces and electrics, reporting the problem promptly and preventing repeated water entry can reduce further harm while the cause is assessed.

Scope note

This guide covers immediate safety, reporting and damage-limitation steps only. Permanent repairs, electrical testing, structural assessment, drying and responsibility for costs may require competent contractors, an insurer, a landlord, a managing agent or specialist housing advice.

Important note

This is general information, not professional building, electrical, legal or insurance advice. Do not enter an unsafe area or attempt work at height. Follow instructions from emergency services, your electricity provider, your landlord, your insurer and competent contractors.
