Ok, you have to find out firstly if you have an isolator running up to the offending tap.
( An isolator, turns off the water supply to that tap. - they can be many shapes and designs. but, [ wished I could post a pic here to show you typcal examples].. some may just look like little red arrows ontop of a silver valve some are buttons, some are windy wheel thingies)
If you can't see where to isolate, then you need to drain off your hot water tank. ( I know you wont be able to open the bath tap to do it - but you can open any other hot water taps)
First. you have to turn off your COLD water supply where it comes into your house. ( that's because, when you empty your hot water tank, the cold water will just keep refilling it. ad infintum)
and, you MUST turn off your boiler.
( That's because there will be no water in the hot tank )
ok so far?
Recap:
Turn off boiler
Turn off cold supply (where it comes into the house)
Open hot taps.

(While the hot water is draining from the tank. you could check if there's still enough water in the kettle....... - one sugar for me)
