As part of refurbishing a house we have had a complete re-wiring by a qualified electrician. He didn't do much in the garage, except re-use an old consumer unit and connect the few appliances in the garage to a couple of circuits on the CU. The garage consumer unit is supplied from the main board on a 32 amp mcb (not rcd protected).
The question is what rating of mcb could be put in for a new ring main in the garage? Presumably it would need to be less than 32 amp as there will continue to be other circuits in use, albeit not drawing much power.
