What an emergency visit may cost
An urgent plumbing call-out often starts around £100–£120, with parts and longer repair work charged separately. Nights, weekends and bank holidays can cost more. Ask what the call-out includes and whether the first visit is intended to stop the leak or complete the repair.
Limit damage safely
If you can reach it safely, close the relevant isolation valve or the property's stopcock. Keep away from water near electrical equipment and call the electricity network or emergency services if there is immediate danger.
Information to prepare
Tell the plumber where the water is coming from, how quickly it is flowing, whether it stops when isolated and whether neighbouring properties could be affected.
