Simple quick question

Im going to put a new feed to a boiler, into a switched spur as it is now..

The cable being used at the moment is black rubber flex with a 3a fuse. (not sure if this was done right in past)

What size cable do i replace this with..?

Is 0.75 heat resistance flex Ok on a 3a fuse? or does it have to be bigger csa?
