I assume these are the old type sockets with no fuse?
Personally, I'd not chance it. After all where is the over current
protection if things go belly up?

In the consumer unit. If they're on the lighting circuit it's likely to
be a 5 or 6 amp radial circuit. You can still buy the BS546 plugs and
sockets, I use them for exactly the same purpose, wall mounted sockets
for table lamps or lighting under kitchen cupboards switched from the
same wall switch as the ceiling lights.

I used to have some 3 pin 5 amp plugs and sockets, which had a fuse in them,
very little things, I don't think one can get them any more.

MK make fused and unfused round pin plugs, to meet the regs the 15A
can't be supplied with a 13A fuse, so are supplied with 5A.
