What to Do When You Have a Burst Pipe: A Step-by-Step Guide
October 27, 2026

Share this post:

A burst pipe is one of the most stressful things that can happen in a home, with water spreading fast and the potential for genuinely significant damage the longer it continues. Knowing exactly what to do in the first few minutes can make a real difference, which is why P C Kelly put together this clear, step-by-step guide.


Staying calm and working through a clear sequence of steps, rather than panicking, gives you the best chance of limiting damage before professional help arrives.


This guide walks through exactly what to do when you discover a burst pipe, from the first critical minutes through to getting it professionally repaired.


Immediate Steps to Take

The very first thing to do is turn off your main water supply, usually located under the kitchen sink, near the stopcock, or where the water enters the property. Turning this off stops more water from flowing into the affected area.


Next, turn on any cold taps around the house to drain the remaining water from the system, reducing the amount that continues to leak from the burst pipe itself while you wait for help.


If the leak is anywhere near electrical sockets, switches or appliances, turn off the electricity at the consumer unit as a safety precaution, since water and electricity together pose a genuine safety risk.


Locating Your Stopcock in Advance

Knowing exactly where your stopcock is before an emergency happens saves precious time when it matters most. Take a moment now, before any issue arises, to locate and test that yours turns off smoothly.


If your stopcock feels stiff or difficult to turn, it is worth having it checked and serviced, since a stopcock that will not turn in an emergency significantly limits how quickly you can respond to a burst pipe.


Limiting Damage While You Wait

Once the water supply is off, focus on limiting damage to your property. Move any valuable or electrical items away from the affected area, and use towels, buckets or a wet vacuum to manage standing water where safe to do so.


If water has reached a ceiling or light fitting, avoid switching on any nearby lights, and consider carefully, and safely, piercing a small hole in a bulging ceiling to release trapped water in a controlled way, preventing a larger, more sudden collapse.


Photographing the damage as you go is worth doing for insurance purposes, giving you a clear record of the situation before repairs begin. Once safe, call a plumber promptly to assess and repair the burst pipe itself.


Steps to take immediately after discovering a burst pipe:


  • Turn off the main water supply at the stopcock
  • Open cold taps to drain remaining water from the system
  • Turn off electricity at the consumer unit if water is near sockets or fittings
  • Move valuables and electrical items away from the affected area
  • Photograph the damage for insurance purposes
  • Call a plumber to assess and repair the pipe


Getting the Pipe Professionally Repaired

Once the immediate danger is under control, a qualified plumber needs to locate the exact cause of the burst, repair or replace the affected section of pipe, and check the surrounding system for any related damage. Emergency call-out support is available for exactly this kind of urgent situation.


Common causes of burst pipes include frozen pipes expanding during cold weather, general wear and corrosion in older pipework, and physical damage from nearby building work or accidental impact.


Addressing the underlying cause, not just the immediate leak, matters for preventing a repeat incident. If frozen pipes were the cause, for example, additional insulation may be recommended to protect vulnerable pipework ahead of future cold spells.


Preventing Future Burst Pipes

Insulating exposed pipework, particularly in lofts, garages and outdoor areas, significantly reduces the risk of freezing during cold weather, one of the most common causes of burst pipes in the UK.


Keeping your heating on a low, consistent setting during particularly cold spells, even when you are away from home, also helps prevent internal pipes from reaching freezing temperatures.




Frequently Asked Questions


How quickly should I call a plumber after a burst pipe?

As soon as you have taken immediate steps to limit damage, such as turning off the water supply. The sooner a plumber can assess and repair the pipe, the less risk of further damage or a repeat issue.


What usually causes pipes to burst in winter?

Freezing temperatures cause water inside pipes to expand, putting pressure on the pipe walls until they crack or split. This is particularly common in poorly insulated lofts, garages and outdoor pipework.
