External RCD/sockets

My preference would be an RCD at or near the cosumer unit and one in the shed or the external socket. Yes if you have a fridge/freezer out there then some kind of alarm set up too

I found this document that looks pretty conclusive :) 

That article is quite a few years old now and so doesn't cover all the current requirements - e.g. for lighting circuits to have RCD protection (in domestic installations).

Why  CU in garage, why not a few sockets and a switched fused spur as a light switch - no new circuit now, just an extension of existing, less to notify. And the protection is at the house end,,

Generally, it is not a good plan.

If you are planning to have a freezer in the garage it comes under the heading of completely daft, as may well end up losing your Christmas dinner and more.

Who'd want to steal his Christmas dinner?

If we get the rumoured shortage of turkeys this Christmas, there may be a black market in them.
