Most likely cause & what to check
Turn off the water supply using the isolating valve under the sink or the main stop tap.
Open the tap fully to release any remaining water pressure.
For a traditional pillar tap: remove the cover cap, unscrew the headgear, and clean any limescale from the spindle with white vinegar. Apply silicone grease to the thread and O-rings before reassembling.
For a ceramic disc tap: the disc cartridge may be partially seized. Remove the cartridge and check for limescale build-up. Soak in white vinegar for 30 minutes, rinse, and refit.
If the O-ring on the spindle is swollen or damaged, replace it — they cost pennies from any plumbers' merchant.
Reassemble and test. If the tap is still stiff after cleaning and greasing, replace the headgear or cartridge entirely.
