If your not going to do any heavy work in the garage using for example lathes or welders and it's just going to be a few lights and sockets for the usual plug in items you could install a fcu off an existing ring final and then install a 4mm radial from the fcu for everything in the garage, then you wouldn't have any notifiable work

It's a 'requirement' of BS 7671 but, as has been said, compliance with that is not a legal requirement, nor 'mandatory' for any other reason.
You theoretically would have to give it to yourself and then, I suppose, show it to anyone who had a legitimate reason for wanting to see it ()e.g. a prospective buyer of your house) - but, again, there is no compulsion to do any of that.
It would seem that some people are more concerned about 'rules and regulations' (even 'non-mandatory' ones) than about common sense.

Why would you need a FCU when using 4mm² - or vice versa?
You don't 'have' to but I prefer to have a simple way to isolate a garage circuit, of course you can just spur the 4mm straight off an existing ring final socket.
Id also prefer to blow an fcu fuse if the garage circuit is overloaded than just trip an mcb in the cu which may disrupt others I the property.

That's not the point/question EFLI was making/asking. If you have an FCU, then you wouldn't need 4mm² cable.
Also, in terms of what you've said you could have your 'simple way to isolate the garage' provided by a DP switch - but if the circuit was protected by a 32A device, then you would need 4mm² cable.
You may be lucky, but I wouldn't put money on the FCU fuse blowing first.

The trouble is that sparks advertise themselves in local papers and on postcards in the newsagents' windows variously described as "Part P electrician", "Registered electrician" and "Certified electrician", amongst others.
The general public believe these descriptions to mean the person is qualified to work as an electrician.
Indeed - whereas, of course, none of those descriptions mean anything useful at all!
