Most likely cause & what to check

1

Turn off the water supply under the sink using the isolating valve, then open the tap to drain remaining water.

2

For traditional pillar taps: remove the headgear and replace the rubber washer at the bottom. They cost pennies.

3

For ceramic disc taps: the cartridge has cracked. Remove the tap head, pull out the cartridge, and take it to a merchant to match the replacement.

4

For single-lever mixer taps: remove the lever, unscrew the cartridge retaining nut, and replace the cartridge.

5

Reassemble in reverse, turn water back on slowly, and test.
