The call sign goes with boat, not yourself or the radio.
You register a radio or radios for to vessel.
You can register a hand held for use on more than one boat. In this case you will not get a call sign, you would use the call sign for the boat you were on at the time.
In practice you tend to use the boat name when calling and not the call sign, unless there is a distress situation, and even then it is not mandatory.
Registration is £12 p.a for a fixed set and you are issued with a "tax disk" to display on the boat.
I understand there is a £4000 (max) fine for having an unregistered radio.
