Emergency drain unblocking, day or night
A blocked drain rarely picks a convenient moment. When the toilet is filling instead of flushing, the kitchen sink is standing full or the outside drain is overflowing across the path, you need someone who answers the phone and turns up.

While help is on the way
- Stop using the affected toilet, sink or shower, and do not run the washing machine or dishwasher.
- Do not pour chemical unblockers down the drain. They rarely clear a full blockage and make it unsafe to work on.
- If sewage is surfacing outside, keep children and pets away from it.
- If water is coming through a ceiling or near electrics, switch the circuit off at the consumer unit.
- Take a photo if you can. It helps us know what to bring.
What counts as an emergency
- Toilet overflowing or refusing to flush
- Sewage backing up into the bath, shower or sink
- Outside drain or gully overflowing
- Manhole cover lifting or flooding
- Every drain in the house slow at once
- Bad smells from drains after heavy rain
