TL;DR
A burst pipe, a leak through the ceiling, or a tap that’s suddenly run dry all count as plumbing emergencies. The right first move is the same in every case. Find your stopcock, turn it off, and get the electrics away from the water before you worry about anything else. Most Slough properties have the stopcock under the kitchen sink, or just inside the boundary where the supply enters the property. If it’s happening now, send us the details online and mark it URGENT, rather than searching for a phone number. That gets a real person looking at your job fastest.
Water coming from somewhere it shouldn’t? Do these three things first
It doesn’t matter whether the water’s dripping through a light fitting, spraying from under the sink, or the taps have simply stopped running altogether. The sequence is the same.
- Isolate the water. Turn the stopcock clockwise until it stops. In most Slough homes this is under the kitchen sink; in older 1930s-60s properties it can also be found in a hallway cupboard or, less usefully, buried under a garden slab near the boundary. If you genuinely can’t find it, turning off the supply at the internal stop valve for the affected fitting (under a toilet cistern or basin, for example) is the next best thing.
- Isolate the electrics if water’s anywhere near them. If water is coming through a ceiling near a light fitting, or pooling near sockets, switch off the circuit at the consumer unit rather than working around it. Don’t touch switches or fittings with wet hands.
- Contain what you can. Buckets, towels, and moving anything valuable off the floor buys time and limits the damage while you sort out what happens next.
None of this needs specialist tools or experience. It’s the same three steps wherever you are on our patch. It’s also the same routine covered on our Langley plumbing page for anyone that end of the borough.
Where’s my stopcock, and why does it matter
The stopcock, sometimes called the stop tap, is the valve that controls the mains water coming into your property. Knowing where it is before you need it is the single biggest difference between a five-minute inconvenience and a soaked ceiling. If you’ve never checked, do it today. Under the kitchen sink is the most common spot, but utility cupboards and understairs spaces are common too, especially in older estate housing built through the 1950s and 60s.
It’s worth knowing the boundary of responsibility here too. Everything from your stopcock into the property is yours to sort out. If the problem looks like it’s out in the street rather than inside your boundary, that’s a mains-side issue instead. It’s worth flagging when you get in touch, so it can be pointed the right way.
Making the property safe, and what to photograph for later
Once the water’s off, don’t just stand and watch it. Open a tap downstairs from the leak to relieve any pressure still in the pipework. If a ceiling is bulging with trapped water, it’s genuinely safer to pierce it in one controlled spot with a screwdriver. Let it drain into a bucket, rather than let it collapse on its own. Move electricals, rugs and anything irreplaceable well clear. If the property is a flat, or shares a supply with neighbours — common in parts of Langley and around Slough town centre — let them know too. Your stopcock might not be the one controlling their water.
Before you mop up too enthusiastically, take a few photos. Photograph the source of the leak, the extent of any ceiling or wall damage, and the meter reading if you can get to it safely. This isn’t about building a case for anyone. It’s simply useful for whoever attends afterwards to understand what happened, before things got tidied away. It’s also useful for you, if you need to talk to your home insurer. It takes thirty seconds and saves a lot of explaining later.
FAQs
Where is my stopcock?
Most commonly under the kitchen sink. In some older properties it’s sometimes in a hallway or understairs cupboard instead. If you can’t find it, isolating the specific fitting (basin, toilet, washing machine) at its own valve is a reasonable interim step.
Should I turn the electrics off?
Yes, if water is anywhere near light fittings, sockets, or a consumer unit. Switch off the affected circuit at the consumer unit, or the whole supply if you’re unsure which circuit. Never touch a switch with wet hands.
What actually counts as a plumbing emergency?
Anything where water is actively escaping, and can’t be stopped by isolating a single fitting, counts. That includes a burst pipe, a leak you can’t locate, or a complete loss of water to the whole property. A dripping tap or a slow trickle from an overflow, while annoying, can usually wait for a scheduled visit instead.
