How to find an emergency plumber in the UK

Before searching for a plumber, take immediate action to limit damage. For a burst pipe or major leak: locate your stopcock (typically under the kitchen sink, in the utility room, or at the property boundary) and turn it off clockwise to cut the water supply to the property. If you cannot find the stopcock, water suppliers have an emergency line and can remotely reduce pressure.

For a boiler fault showing an error code: look up the code in your boiler's manual or online (manufacturer + "fault code" + code number) before calling an engineer — many codes indicate simple user-resettable faults requiring only a pressure top-up or reset. Calling an engineer for a problem you can fix yourself costs £80–£150 for a 20-minute callout.

For a serious water leak that is causing structural damage or electrical risk: call 999 if there is an immediate safety risk; call your home insurance emergency helpline, which typically provides 24-hour access to vetted tradespeople at no additional cost.

The fastest routes to an emergency plumber: (1) your home insurance emergency line — check your policy documents, as most home insurance includes 24-hour emergency access; (2) Gas Emergency Freephone 0800 111 999 if you smell gas; (3) a local plumber you have used before; (4) a search on Yolist or Google for "emergency plumber [your city]".

When calling any emergency plumber, ask four questions immediately: Are you Gas Safe registered (if gas work is involved)? What is your emergency callout fee? What is your hourly rate after the first hour? When can you attend? Legitimate emergency plumbers answer these questions clearly and upfront.

Avoid plumbers who refuse to give a callout fee over the phone, demand cash-only payment before starting work, or give an extremely vague time of arrival window ("sometime today"). These are common indicators of rogue traders who exploit emergency situations.

Emergency plumbing is legitimately more expensive than scheduled work. Reasonable emergency callout fees (2025–26): daytime (8am–6pm, weekdays) £60–£120 including first hour; evenings and weekends £90–£180 including first hour; Christmas and Bank Holidays £150–£250 including first hour. Hourly rates after the first hour: £50–£80 daytime; £65–£100 evenings and weekends.

Always ask for a written quote or at minimum a clear verbal statement of costs before authorising work. If the plumber cannot give you a cost estimate before starting work on a visible, accessible problem, this is unreasonable. For straightforward fixes (reseating a valve, tightening a fitting), the first hour should be sufficient.

If you receive an invoice that significantly exceeds what was verbally agreed, you are entitled to challenge it. Dispute it in writing within 14 days, citing the verbal agreement and the Consumer Rights Act 2015. Citizens Advice can provide free guidance if the dispute escalates.
