Emergency plumber: what to do first in a plumbing emergency

A plumbing emergency can cause serious damage within minutes, but taking the right first steps can limit the problem while you arrange professional help. Whether you have a burst pipe, an overflowing toilet or no hot water for a vulnerable person, use this checklist to make your property safer before calling an emergency plumber.

1. Stop the water supply

Find and turn off your internal stop tap as soon as possible. It is often under the kitchen sink, near the front door, in a utility room or beside the point where the water supply enters the property. Turn it clockwise, but do not force it if it is stiff, as a damaged valve may need professional attention.

For a leaking washing machine, dishwasher or toilet cistern, use the local isolation valve if one is fitted. Stop using taps, toilets and appliances connected to the affected pipework until the source has been checked. If you are unsure where the stop tap is, our plumbing services can help with emergency repairs and practical advice.

• Turn off the internal stop tap.

• Isolate the leaking appliance or toilet if possible.

• Open a cold tap briefly to release pressure, then close it.

• Call an emergency plumber if water continues to escape.

2. Keep electricity and water apart

Water near sockets, light fittings, appliances or your fuse box creates an electric shock risk. Do not touch wet switches, plugs or electrical equipment, and do not walk through standing water to reach the consumer unit.

If the consumer unit is in a completely dry, accessible area and you can switch off the electricity without coming into contact with water, do so. Otherwise, leave the property or move to a safe area and contact a qualified electrician as well as a plumber. Never take risks to protect belongings.

3. Contain the leak and protect your home

Once the water supply is isolated and the area is safe, place buckets or bowls beneath drips and use towels to slow the spread. Move furniture, rugs, electrical items and other valuables away from the affected area, provided you can do so safely.

A burst pipe may continue releasing water until pressure has reduced, while a leaking hot water cylinder or overflow can keep causing damage even after a tap is closed. Do not remove panels from a cylinder, boiler or heating appliance unless a qualified professional has instructed you to do so.

4. Avoid chemical drain cleaners

If a sink, bath or toilet is blocked, do not pour chemical drain cleaner into it before calling a plumber. These products can cause burns, damage pipework and create a hazard for the person who later dismantles the trap or toilet.

For a blocked toilet that is overflowing, turn off the toilet’s isolation valve if available and avoid flushing again. Keep children and pets away from contaminated water, and tell the plumber if any cleaning product has already been used.

5. Record the problem for your plumber

Take clear photos or short videos of the leak, damaged areas, warning lights or the appliance involved, but only if it is safe to do so. Note when the problem started, what happened immediately beforehand and whether the water is clean, dirty or hot.

This information can help an emergency plumber bring suitable equipment and make the callout more efficient. It can also support an insurance claim if flooring, ceilings, furniture or other parts of the property have been damaged.

Common emergencies needing prompt help

Burst pipes and serious leaks

A burst pipe needs urgent isolation and professional repair. Check cupboards, ceilings, loft spaces and utility areas for spreading damp, but do not enter a flooded area if electricity may be present.

Leaking hot water cylinders and overflows

Hot water can scald, and a cylinder leak may damage floors and ceilings quickly. Keep people away from the area, turn off the water supply if safe and contact a qualified plumber. For heating-related faults, you may also need boiler repair from a suitable heating engineer.

No hot water in a vulnerable household

A loss of hot water may become an emergency where occupants include babies, elderly people or anyone with health needs. Check whether the boiler has power and whether the controls show an error, but do not repeatedly reset it or remove its casing. Arrange professional help through boiler repair services.

Suspected gas leak

A suspected gas leak is a gas emergency, not an ordinary plumbing problem. Do not use electrical switches, flames or mobile phones inside the property; leave immediately, warn others and call the National Gas Emergency Service on 0800 111 999 from outside. Only after the situation has been made safe should you arrange gas work with a Gas Safe registered engineer.

Information that speeds up a callout

When you contact an emergency plumber, explain the property type, the exact location of the problem and whether the water has been isolated. Mention where the stop tap is, how long the issue has been happening, whether the water is hot or dirty and whether there is damage to ceilings, floors or electrics.
