Burst Pipe Emergency: What to Do in the First Hour

A burst pipe can soak through a ceiling in minutes, and what you do in the first ten minutes makes most of the difference to the damage. This guide covers the practical steps in order, with a few tips for Burnley's older terraced houses, and the lockouts and locked cupboards that can slow you down when every minute counts.

Step one: stop the water

Find your internal stopcock and turn it clockwise until it stops. In most Burnley terraces it is under the kitchen sink, but in houses with a cellar it is often low on the front wall where the supply pipe comes in from the street. Some are under the stairs or behind a panel in a downstairs cupboard.

If the stopcock is seized, don't lean on it with a big wrench, because an old brass valve can snap and make things worse. Use the outside stop tap instead. It usually sits under a small metal or plastic cover in the pavement or front path and needs a stop tap key, which costs a few pounds from a hardware shop. In some older terraces one outside tap supplies more than one house, so tell your neighbours before you turn it off.

  • Turn off the water at the stopcock or outside stop tap
  • If water is near sockets, light fittings or the consumer unit, switch the electrics off at the main switch, but only if you can reach it without standing in water
  • Turn off the boiler and any immersion heater
  • Open the cold taps and flush the toilets to drain what's left in the pipes
  • If a ceiling is bulging, put a bucket underneath, stand well back and make a small hole with a screwdriver to let the water out in a controlled way

Limit the damage and protect your claim

Once the flow has stopped, move electrical items, rugs and valuables out of the wet area. Before you mop up, take photos and a short video of the leak, the wet ceilings and the damaged belongings. Insurers usually class this as an escape of water claim, and clear evidence taken on the day makes it much easier.

Ring your insurer early, as many have a 24 hour claims line and approved tradespeople. Keep receipts for anything you pay for, such as dehumidifier hire or emergency repairs, and don't throw out damaged items until the insurer says you can. A pipe repair clamp or self-amalgamating tape can hold a small split until a plumber arrives, but only as a stopgap.

Who to call

For a burst inside the house, you need a plumber. Out-of-hours call-out charges vary a lot depending on the time, the day and the job, so ask for the call-out fee and hourly rate before they set off. If you rent, tell your landlord or letting agent straight away, because repairs to the water supply are normally their job.

If water is coming up from the pavement or the leak is on the street side of your stop tap, contact United Utilities, who supply water to Burnley. They are responsible for the pipe up to your property boundary.

When a locked door is the problem

We're locksmiths, not plumbers, so we can't repair your pipe. But a surprising number of emergency calls start with a burst pipe. Water might be coming through your ceiling from a flat above while the neighbour is away. Or the stopcock might be in a locked meter cupboard or communal plant room, or you might be locked out while water runs inside.

In those cases, getting in quickly and without damage is what matters. Most standard domestic locks can be opened without breaking anything. We'll need proof that you have the right to enter, such as a tenancy agreement, a council tax bill, or permission from the landlord, managing agent or owner. We won't open someone else's property without proper authority. If the door or frame has already been damaged getting in, we can make it secure before you leave the property empty to dry out.

Stopping it happening again

Most burst pipes in east Lancashire happen during or just after a hard frost, when frozen water splits a pipe and then leaks once it thaws. Houses on higher ground around Burnley can drop well below freezing on winter nights.

  • Lag pipes in lofts, cellars, garages and against outside walls
  • Keep the heating on low, around 12 to 15°C, if you're away in winter
  • Find your stopcock now, and turn it off and on twice a year so it doesn't seize
  • Fit an insulated cover to outside taps and turn off their isolation valve over winter
  • Leave a spare key with someone nearby you trust, so they can get in if something goes wrong while you're away

Frequently asked

Is a burst pipe covered by home insurance?+
Most buildings and contents policies cover damage from escape of water, though the fixing of the pipe itself may not be covered and there is usually an excess. Some policies exclude damage if the house was left empty for a long time, often 30 or 60 days, so check your policy wording.
Who is responsible for a leaking pipe outside my house?+
In general, United Utilities is responsible for the pipe up to your property boundary, and the homeowner is responsible for the supply pipe from the boundary into the house. If you're not sure where the leak is, report it to United Utilities and they can advise.
Can a locksmith let me into a neighbour's flat if water is coming through my ceiling?+
Only with proper authority, such as permission from the owner, landlord or managing agent. If nobody can be reached and the damage is serious, contact the managing agent's emergency line or the police, and we can work alongside them.
