How can I get cold water to my bathroom sink and toilet cistern?

the water in the shower might be comming from a tank up in the loft, and the bathroom sink and toilet , might be fed from the mains, not sure if this bathroom is upstairs or down , it could be getting air locked. try getting a small lenth of hose, 1 foot, long , put one end into the cold tap were the water should come out , and the other into the hot tap, so your linking the two taps , open the cold tap all the way, now slowley turn the hot tap on, to send the water through , cold tap and back down ,its empty pipes to hit the air lock , and move the blocked water, to get it flowing again, ps wear gloves, worth a try ..
