No water coming from a tap

Most likely cause & what to check
First check whether other taps in the property are also affected — if so, the problem is with the incoming supply or stop tap, not the individual tap.
Check the isolating valve on the supply pipe under the sink. The slot in the screw should be in line with the pipe (open). If it's across the pipe, it's closed — turn it 90° to open.
Check your main stop tap under the kitchen sink is fully open.
If it's a hot water tap only: check the boiler is running and that hot water is available from other outlets.
Check the tap itself — the jumper or ceramic disc may have become completely dislodged or lodged shut. Dismantle the headgear and inspect.
If the supply pipe under the sink feels very cold in winter, the pipe may be frozen. Gently warm with a hairdryer, starting from the tap and working back.
