What size fuse for wall mounted bathroom fan heater

Hello,
I am replacing the wall mounted 2 KW bathroom fan heater with another one that is same size and specifications. The cable to it runs from a fused switch box in the loft. Just checking what fuse should be in that switch box please. At the moment it is 5amp. Is that correct size ?
Thanks

It draws about 8.3Amps so a 10A fuse would do but a 13A would be normal.

A 5A fuse is operating beyond its rated capacity and would get hot and eventually fail.

However

Is it fed from a lighting circuit?
