Urgent make-safe?
Call 020 7101 3168 first with the postcode and immediate risk. Online briefs are better for planned follow-up once the situation is controlled. Read the emergency triage guide for emergency plumber or the full emergency hub.
What do you need?
Choose the job. Each one says what to send, and whether to call.
Water still running
Call with the postcode. If it is safe, isolate at the stopcock and say which rooms are wet.
Call 020 7101 3168A burst that has stopped
Send photographs of the pipe, the ceiling or floor below, and what you have already isolated.
Send this in a briefMake-safe, then a repair
Stopping the water and completing the repair are separate written steps. Say which one you need now.

Call first for an uncontrolled water emergency
A burst pipe, rapidly spreading leak or active flooding needs a phone triage before an online brief. Give the full postcode, the source if visible, whether the water can be isolated, the rooms affected and any vulnerable occupants or building-access restriction. We confirm current capacity, the call-out price basis and the available response before dispatch. This page does not promise a fixed arrival time or continuous availability.
The first safe actions before emergency plumbing attendance
If it is safe and you know how, close the internal stop tap or the local isolation valve and move people and possessions away from the water. Do not touch wet electrical equipment, exposed wiring or a consumer unit in a wet area. If the source is communal, contact the building’s emergency or managing-agent number as well. Photographing damage is secondary to personal safety and isolation.
What counts as make-safe rather than a permanent repair
Emergency work may isolate a supply, stop active water, cap a failed connection or restore limited safe use. That does not always complete the underlying repair. Concealed pipe replacement, drying, ceiling opening, joinery removal or bathroom reinstatement may need a separate planned scope after the immediate risk is controlled. The attendance record should make that boundary explicit so “leak stopped” is not mistaken for “all damage repaired.”
Information that improves dispatch triage
Useful details include the property type and floor, internal stop-tap position, affected fixture, visible pipe material, photographs, ceiling or wall spread and whether a neighbour or porter has access. State if water is entering from another flat or escaping into one below. For a locked plant room, communal riser or external stop tap, identify who can authorise and provide access before an engineer is sent.
Burst pipes, leaking pipes or blocked drains?
Pipe repairs, an overflowing appliance connection and blocked drains can require different equipment and isolation. Describe whether clean water continues when taps are closed. Explain whether using a fixture triggers the leak or causes waste to back up. Loss of hot water or a heating-system fault may need a different planned route. Do not use chemical drain products while attendance is being arranged unless a competent person has specifically advised it. Phone triage determines whether the reported issue belongs with emergency plumbing, drainage or a planned heating service.
Gas escapes and carbon-monoxide alarms use emergency routes
A suspected gas escape is not an ordinary emergency-plumber booking. Leave the area, avoid flames and electrical switches, and contact the National Gas Emergency Service on 0800 111 999 for Great Britain. If a carbon-monoxide alarm sounds or exposure is suspected, stop using the relevant appliances if safe, go outside, do not re-enter until advised and obtain medical help. Call NHS 111 for suspected symptoms, or 999 for severe symptoms or immediate danger. Any later gas work must be assigned to a Gas Safe-registered engineer for the accepted scope; a water-leak call-out does not replace either emergency route.
Leaks in flats and communal systems
In a mansion block or converted house, isolation may sit outside the affected flat and the failed section may be communal. Contact the porter, freeholder or managing agent when their access or approval is needed. Tell neighbours below when water is spreading if it is safe to do so. We can confirm the attendance we are able to offer, but ownership, insurance liability and communal authority are not decided by this service page.
Emergency call-out pricing and the follow-on decision
Before dispatch, we confirm the available call-out fee or other price basis wherever circumstances reasonably allow. Parts, extended diagnosis, specialist access and reinstatement may sit outside that initial basis. They must be agreed before additional planned work proceeds. After make-safe, the next step may be no further work, a quoted pipe repair, drying or damage assessment. It may instead be a referral to the relevant building or insurance contact. No deposit outcome or insurer decision is promised.

People Also Ask About Emergency Plumber
Can the water company turn off my water supply because of a leak?▼
Yes, in an emergency. Section 75 of the Water Industry Act 1991 lets a water undertaker in England or Wales disconnect the service pipe or otherwise cut off the supply where it believes water is being contaminated, wasted, misused or unduly consumed, or that a defective water fitting is causing damage, and the case is an emergency. Otherwise it must serve notice allowing at least seven days to put matters right.
Source: Section 75, Water Industry Act 1991, legislation.gov.uk
Do I need to tell the council before emergency repairs to an underground drain?▼
In an emergency you may start at once, but you must not cover the drain over without giving the local authority at least 24 hours' notice. Section 61 of the Building Act 1984, which applies in England and Wales, otherwise requires that 24 hours' notice before repairing, reconstructing or altering the course of an underground drain communicating with a sewer. Failure carries a fine at level 3 on the standard scale.
How deep does a water pipe have to be buried to stop it freezing?▼
Deep enough that the water inside cannot freeze; no fixed depth is set. Paragraph 7(4) of Schedule 2 to the Water Supply (Water Fittings) Regulations 1999, which applies in England and Wales, requires any water fitting laid below ground level to have a depth of cover sufficient to prevent water freezing in the fitting. The same paragraph also bars embedding water fittings in walls or solid floors.
Source: Schedule 2, paragraph 7(4), Water Supply (Water Fittings) Regulations 1999, legislation.gov.uk
Is it against the law to leave a leaking or faulty plumbing fitting?▼
Yes, where it wastes or contaminates mains water. Regulation 3 of the Water Supply (Water Fittings) Regulations 1999, which applies in England and Wales, prohibits installing, connecting, arranging or using a water fitting in a way that causes or is likely to cause waste, misuse, undue consumption or contamination of water supplied by a water undertaker. The same prohibition covers damaged, worn or otherwise faulty fittings.
Source: Regulation 3, Water Supply (Water Fittings) Regulations 1999, legislation.gov.uk
Should I be able to isolate one appliance without draining the whole system?▼
Yes. Paragraph 11 of Schedule 2 to the Water Supply (Water Fittings) Regulations 1999 requires water supply systems in England and Wales to be capable of being drained down and fitted with an adequate number of servicing valves and drain taps, so as to minimise the water discharged when fittings are maintained or replaced. Paragraph 16 requires a servicing valve on every cistern inlet pipe adjacent to the cistern.
Source: Schedule 2, paragraphs 11 and 16, Water Supply (Water Fittings) Regulations 1999, legislation.gov.uk
Why does my house smell of drains?▼
Foul air reaches the room when a trap loses its water seal. Approved Document H, which supports the Building Regulations in England, says all points of discharge into the drainage system should be fitted with a trap to stop foul air entering the building, retaining a minimum seal of 25mm of water under working and test conditions. Table 1 sets 75mm seal depths for washbasins and sinks.
Source: Approved Document H, paragraphs 1.3-1.4 and Table 1, GOV.UK
Why is water running from the discharge pipe on my hot water cylinder?▼
Water from that pipe means a safety device on the cylinder has discharged. Requirement G3(3) of Schedule 1 to the Building Regulations 2010, which applies in England, requires a hot water system with a storage vessel to incorporate precautions preventing the stored water exceeding 100°C, and to ensure any discharge from safety devices is conveyed to where it is visible but will not endanger people.
