water stopped in main bathroom only

Yesterday the cold water stopped in main bathroom, it had been slowing down for a number of days. The cold tap in the sink & in the bath have now stopped and no water is going to cistern. All the other taps (kitchen, utility, ensuites) are fine. Any thoughts on where to look - not seeing any pipes for the bathroom only - seems strange that only the main bathroom is a problem.

make sure that your kids havent turned off any valves in the hotpress although it sounds like a blockage in the pipework you may nee to get into the attic and check to see if the pipes comming from the tank arent blocked.
