UK Armoured cable to garden shed

Not if it’s getting boxed in.

Yes if you’re planning a joint box in the bathroom to convert cable from T&E to SWA for example.

Why would converting from T&E to SWA require RCD protection? I take it as an almost given that this cable isn't going to be sunk into the wall at any point.

Rcd to cover anything within a bathroom.
Not serving anything in a bathroom, but a joint would introduce a possibility of a loose connection. Was just an example.
Boxing it in takes it outside the bathroom area if it’s inaccessible..

Even an SWA running through a bathroom would need RCD protection (oh what an eyesore that would be!). Don't see why a junction box requires RCD protection for a possible loose connection, it's not there to cover off poor workmanship.

Small correction, if I may.
Cables passing through zone 1 or zone 2 require RCD protection.
A cable completely enclosed in boxing-in would be regarded as being outside the zones.
