Which is the best fuse to use (3A, 5A or 13A) with a 1.15kW
electric fire at a potential difference of 240v
Assuming you mean at the BS1363 plug then the fuse should be sized
to protect
the cable.

Nice, that's the sort of answer I'd expect :-)
Does the BS require that the heating element should burn out before the
cable does (say there's a voltage surge)?
And does the BS require that the element will burn out safely without
setting fire to something?
I don't think that BS761 has an opinion on it. Overload is not relevant
(the load is set by the heaters wattage) so in this case only fault
current applies.
If you have such a voltage surge then the least of your worries would be
a 1.15kW heater!
