I'm more of an old imperial measurement type (AWG/SWG etc) but
believe that 1.5mm is *way* too thin to make an extension lead out

Until someone borrows it for a not-so-lightly-loaded application.

Perhaps you didn't know, but UK plugs have a fuse in them?

I do, but am grateful for the reminder. However, not everyone installs
the appropriate fuse.

But a 13 amp fuse is correct for 1.5mm cable...

not if it's still coiled in a reel, The current carrying capacity is
reduiced by 75%. ie to 12A, so: use a 10A fuse in case.

Do you mean reduced by 75%, so the current capability is nearer 4A?

Short term use even at 13A would be fine, however a 10m reel will
dissipate 24W for a 10A load. I can assure you a well insulated reel
will eventually get above 70C internally, the limit for PVC.
