They're not. Last time I looked, MK (large, and good, manufacturer of
plugs, socket outlets, light switches, etc), listed their 13A BS1363 plug
with either a 3A or a 13A fuse pre-fitted. The fact that very few
companies stock the former is a problem, though.

I can't be the only person to have a jam jar full of new 13A fuses that
I'vve removed from new plugs that I am fitting...

I don;t beleive you should ever fit a 1A fuse in a BS1363 mains plug. I
have never need a 1A fuse that complies with BS1362 (the lowest rated
such fuse I've seen is 2A), the 1A fuse may not be able to stand the
fault current without exploding, say.

I regard those moulded-on plugs as being dangerous!. They do not have
proper strain-releive for the cable (many times the outer sheath has
pulled out of the mounted plug body, you xan't check the wires are
properly connected (not just haning on a couple of strands), darn it,
I've had them with live/neutral reversed.
Most of the time I cut them off and fit an MK or Duraplug (acutally the
same company). Then I know it's done properly.
Oh, and watch out for another thing. At least one country uses a
connecotr that is mechancially compatible with the UK BS1363 13A socket,
but on a 15A radial circuit. This is not a problem, the connector will
easily handly 15A _but_ the plugs used in that country generally do not
contain fuses. Somewhere I have a 'kettle lead' with what appears to be
an unfused 13A plug on one end.. Needless to say using that on the normal
UK ring main circuit (fused at 30A) could be dangerous.
