Emergency callout, 24/7

Emergency plumber across London

A ceiling dripping into the room below. A pipe that has failed somewhere inside a wall. Taps that give nothing, anywhere in the house. Problems like these never hold off until Monday morning, so the Ninja Plumbers booking line does not close either. When you ring, we explain the first steps to take while an engineer is already heading to you.

The work

Included in the job

  • Bank holidays, weekends, evenings and nights
Good to know

Read this before you ring

You may find you can sort some of this yourself, without calling us. We are fine with that, and would rather you knew it.

Water is flooding in

Your first job is the stopcock: turn it clockwise until it will go no further. In most London homes it sits under the kitchen sink or in the cupboard beneath the stairs, and in a flat it is often just inside the front door. With it closed, run the cold taps through the house so the pipes empty. In those first five minutes, nothing cuts the damage more than doing this.

Water is dripping through the ceiling

Keep out from under any ceiling that is sagging, and leave the light fittings in that room alone. Where water could be reaching electrics, cut the electricity at the consumer unit and keep it off. After that, ring us.

The leak is nowhere to be seen

Close the stopcock and keep an eye on the water meter, if there is one. A meter that is still turning means the leak sits on the supply side of the stopcock, which usually makes it the water company’s problem and not yours. Mention this when you ring and nobody makes a wasted journey.

The taps have run dry

Before ringing us, find out if your neighbours still have water. When the whole street has lost supply, the fault is on the Thames Water mains and no plumber can put it right. We will tell you that plainly instead of billing you for a visit.

Calling us

Have these to hand when you ring

  • The postcode, plus the flat number or building name if you're in a block.
  • What you can see, which room it's in, and how long it's been going on.
  • Whether water is still coming through, or has stopped since you turned something off.
  • Where the stopcock is and whether it moved when you tried it — or that you couldn't find one.
  • Access details: where a van can park, any door or gate codes, and a number for the neighbour above if the water seems to be coming from their flat.
Cost

What changes the price

An emergency visit is priced on what the engineer finds when they arrive, and on what it takes to stop the damage there and then. The points below explain why two callouts on the same night can cost quite different amounts.

Whether it really cannot wait

Work that genuinely cannot wait is charged at emergency rates, and you hear the price before the engineer starts, whatever the hour. If the water can be shut off and the repair can safely wait until morning, we will say so.

Making safe, or the full repair

Sometimes the first visit stops the water, isolates the damaged section and gets the rest of the house back on supply, and the proper repair follows once parts or access are sorted. Doing it that way in daylight can cost less than forcing a full repair at night.

Where the failure is

A burst under the kitchen sink is quick to reach. A joint that has let go inside a ceiling void, under a bathroom floor or behind a fitted kitchen means opening something up first, and that access work is part of the price.

A stopcock that will not turn

If the internal stopcock has seized, or it sits in a communal cupboard or another flat, the water has to be shut off somewhere else first — sometimes at the boundary, sometimes by Thames Water in the street. That extra step takes time before the repair can even begin.

We agree the price with you before any work begins, and accept both card and cash.

Your questions

Questions we often get

Will someone pick up at night?

Yes. Emergency callouts run 24/7. The office is staffed from 7am to 10pm every day, and at any other time the same number rings straight through to the person on call.

What makes something an emergency?

Water causing damage at this moment is an emergency. So is having no water or no heating when it truly cannot wait. A tap that drips is not. We would sooner book that in as a normal job than bill you emergency rates for something that will keep until the next day.

What does an emergency callout cost?

You get a price before the engineer begins, out of hours included. We never start work first and only reveal the cost once it is done.

Is it better to phone or fill in the form?

Phone us for anything urgent. The form is read during office hours, so it suits quotes and work that can wait.

What should I do if I smell gas?

Call the gas emergency line before you call us. Leave the property, don't switch lights or appliances on or off as you go, and don't smoke or use a lighter. From outside, ring the National Gas Emergency Service on 0800 111 999. Once they have made it safe, our Gas Safe registered engineers can repair the boiler, cooker or pipework involved.

Water is near the electrics — what do I do?

Treat anything wet as live. Keep your hands off switches, sockets and fittings the water has reached. If the consumer unit is dry, and so is the floor in front of it, switch everything off at the main switch; if not, keep everyone out of that room. We will deal with the water, and our electricians can check any wiring that got wet before it is used again.

Can a landlord or managing agent book on a tenant's behalf?

Yes. Give us the address, the tenant's name and phone number, and who is paying, and we will arrange access with the tenant ourselves. If anything over a set amount needs your approval, say so when you book and we will come back to you before going further. Tenants can ring us directly in an emergency too — it helps to have the landlord's or agent's details to hand.

I am away and a neighbour says water is pouring out of my home. Can you help?

Yes, as long as someone can let us in. A neighbour with a key, a managing agent or a concierge are all common. While the engineer is travelling, we can talk whoever is there through finding and shutting the stopcock, which limits the damage sooner. Tell us on the phone who will meet the engineer and how to reach them, and send any entry codes or gate details by WhatsApp so nothing holds things up at the door.

Will my home insurance pay for an emergency plumber?

Sometimes, but it depends on your policy. Many buildings and contents policies cover the damage caused by escaping water, while the repair to the pipe itself is often treated separately or excluded. Some policies include home emergency cover as an add-on. Ring your insurer, take photos before anything is cleared up, and keep the invoice. If the insurer wants an explanation of what failed, ask the engineer to note it down on the visit.
