- Water you cannot stop. A burst pipe, a leak that continues after the stopcock is off, or water coming through a ceiling.
- Water near electrics. Leaks dripping onto sockets, light fittings or the consumer unit.
- Sewage backing up. Toilets or drains overflowing with waste water inside the home.
- Your only toilet is blocked or broken and cannot be cleared.
- No water at all and your neighbours have water, which suggests a problem on your own supply.
- Flooding from a failed hot water cylinder or tank.
Usually urgent, but can often wait a few hours
- A slow leak you can contain with a bucket, after turning off the local isolation valve
- A blocked sink, if you have another one to use
- A radiator leaking at the valve, if you can isolate it
- No hot water from a cylinder, if you have cold water and it is not winter
Can wait for a normal booking
- Dripping taps
- A toilet that runs on after flushing

What about gas?
If you smell gas, leave the property, do not use switches or flames, and call the National Gas Emergency number on 0800 111 999. Gas leaks need a Gas Safe registered engineer, not a plumber.
What to do while you wait
- Turn off the water at the stopcock or nearest isolation valve
- Switch off electrics near water, if safe
- Move valuables and catch drips
- Take photos for insurance
Frequently asked questions
Is an emergency plumber more expensive?
Usually, especially at night or on weekends. Agree the price before work starts.
How fast can an emergency plumber arrive?
It depends on your location and demand. Call us and we will give you an honest arrival estimate.
Can I fix a leak myself until help arrives?
Turning off the water and catching drips is safe and sensible. Avoid anything involving electrics.
