The best advice would be to junk any extension lead which isn't

correct type of fuse, either junk it or fit one.

What about reducing the fuse to 10 amps to create an added margin of
safety (or even 5 amps if it is only used for electronic equipment)?

Because of the chance of someone else using that piece of equipment. Maybe
even in the distant future.

That's a good point, actually, especially if the extension could
continue working with the fuse running hot. I'll change them back to
13A.

I especially like your footnote (now disappeared) which I can pass on
to certain people :-) .
