Water Coming Through the Ceiling: What to Do First

First, think safety

If water is near lights, sockets or the consumer unit, keep away from the affected electrics and switch off power if it is safe to do so. Do not touch wet fittings or ceiling lights.

Stop the water if you can

If the leak is from your property, turn off the stopcock. If the leak is from a flat above, contact the neighbour, landlord, concierge or building manager straight away. In a managed block, shared risers and communal pipework can also be involved.

• Move furniture and valuables away from the leak.
• Put a bucket or tray under steady drips if safe.
• Take photos before clearing up for records or insurance.
• Do not pierce a bulging ceiling unless advised by a professional.

Why ceiling leaks can be difficult to trace

The visible stain is often only where water has escaped. The actual leak may be a bath waste, shower seal, toilet feed, radiator pipe, heating circuit or hidden joint above the ceiling.

What an emergency plumber will look for

The engineer will usually check bathrooms and kitchens above the leak, exposed pipework, water pressure, heating pressure and any signs around wastes or seals. If access is needed, it should be explained clearly before opening anything.

For urgent ceiling leaks, use the main leak detection and repair service so the visit is focused on finding and stopping the source.
