FAQ

Emergency plumber London — common questions

What counts as a plumbing emergency?

A plumbing emergency is any situation that poses an immediate risk to your property or health. This includes burst pipes, flooding from any source, sewage backing up through drains or toilets, a complete loss of hot water or heating in winter, a suspected gas leak, and any significant uncontrolled water leak. If you can contain the problem safely by turning off the stopcock and it can wait until normal working hours, it may not need an emergency plumber. If you cannot stop the flow of water or the situation is getting worse, call immediately.

How much does an emergency plumber cost in London?

Emergency plumbers in London typically charge £150–£300 for an out-of-hours call-out, on top of parts and labour. During normal hours, call-out charges are lower at £50–£100. A burst pipe repair costs £200–£600 depending on access and pipe location. Full emergency jobs involving flooding or sewage can run higher depending on the extent of the work. Always ask for a clear quote before the engineer starts.

How quickly can a plumber come in an emergency?

Most emergency plumbers in London aim to attend within 1–4 hours for critical situations like burst pipes or flooding. Out-of-hours response for the most urgent jobs — those involving active flooding or gas leaks — is typically 1–2 hours. Response times vary by location, time of day, and demand. Post your emergency on GetQuickHelp and available plumbers will contact you directly with their earliest available time.

What should I do while waiting for an emergency plumber?

First, locate and turn off your stopcock — this is usually under the kitchen sink or where the mains pipe enters the property. Turn off your boiler and central heating system. If there is significant flooding, move valuables away from the affected area and, if safe, isolate the electricity in the affected zone at the consumer unit. Do not enter rooms with standing water if you cannot confirm the electrics are off. Take photos for your insurance claim. If you smell gas, leave the property immediately, do not operate light switches, and call the Gas Emergency Service on 0800 111 999.

Is emergency plumbing covered by home insurance?

Many home insurance policies include emergency home assistance cover that pays for an emergency plumber call-out for burst pipes, flooding, or boiler breakdowns. Check your policy documents or call your insurer before contacting a plumber — some insurers require you to use their approved contractor list. If your policy does not include emergency cover, you will pay directly. Keep receipts as flood or water damage claims can cover the consequential damage even if the initial repair cost is not covered.
