What Should I Do If Water Is Leaking Through the Ceiling?
Water coming through a ceiling is one of the more distressing plumbing emergencies a homeowner can face, both because of the potential damage and because the source is not always obvious. The good news is that a few clear, calm steps can limit the damage significantly while you wait for help to arrive.
This guide covers what to do immediately, how to think about the likely source, and when the situation calls for an emergency plumber rather than something that can wait until normal hours.
Immediate Steps to Take
First, if it is safe to do so, turn off the electricity supply to the affected room at the consumer unit, since water and electrics are a serious combination. Do not touch light fittings or switches in the affected area if they are wet or if water is dripping near them.
Next, move furniture and valuables out of the way and place buckets or towels to catch dripping water. If the ceiling is bulging with trapped water, it is often safer to carefully puncture a small hole to release the water in a controlled way into a bucket, rather than letting a larger area collapse unexpectedly, provided this can be done safely from below.
Isolate the Water Supply
If the leak is coming from a pipe, tank, or appliance in the property above or in the room directly overhead, turning off the stop tap will stop mains-fed leaks, though tanks and cylinders may continue to drain for a period afterwards. Knowing where your stop tap is before an emergency happens is genuinely useful, so it is worth checking now if you are not sure.
Identifying the Likely Source
Common causes of ceiling leaks include a failed pipe joint, an overflowing bath or shower tray, a leaking shower enclosure or seal, a failed washing machine hose, or in colder months a frozen and then burst pipe in a loft space above. Leaks that appear only when it rains outside may actually be a roof issue rather than a plumbing one.
If you live in a flat, the source may be in the property above rather than your own, in which case coordinating access with your neighbour or managing agent will be necessary alongside any plumbing work in your own flat.
When to Call an Emergency Plumber
A leak that is actively running, spreading, or affecting electrics warrants an emergency call rather than waiting. Our engineers can attend to trace and stop the source of the leak, and same-day appointments may be available, though this cannot be guaranteed in every case.
Emergency work outside normal weekday hours is charged at £120 + VAT per hour in the evening (5–9pm) or £185 + VAT per hour overnight and on Sundays and bank holidays, with a one-hour minimum and no separate call-out charge.
After the Leak Is Stopped
Once the source has been isolated or repaired, the ceiling itself will usually need to dry out fully before any redecoration is attempted, and a damaged ceiling may need a builder or decorator to make good afterwards, which is separate from the plumbing repair itself.
It is also worth checking whether your home insurance covers escape-of-water damage, as many policies do, though the plumbing repair and any resulting redecoration are usually treated as separate claims or costs.
