Price will depend on where you want it. Cheapets through wall by kitchen sink. make sure they include an isolation valve inside and that its a brass hose union tap and preferably with no visble external copper pipe (reduce freezing problem). . Should cost around £10/15 materials plus £30/40 labour. More if your pipes below sink dont have isolating valves on.
