If you stick a BS1362 plugtop fuse in a consumer unit and then short
out the lighting circuit, the BS1362 fuse might not be able to break
the resulting high current flow, in which case the 100A main fuse will
be left to do so, which will wreck the lighting wiring and might cause
a fire (much more than 100A will pass).

Or alternatively for maximum safety and lack of false fuse blowing you
replace the 5A CU fuse with a 13A plugtop fuse as the previous owners
of our house had done!!
