PLEASE HELP, need professional advice

I am installing an 8.5kw shower. the electric is already in place to the pull cord. It just needs connecting from the pull cord to the shower itself. I know it's only a case of connecting 3 wires this end, and 3 wires the other end. In the consumer unit, it has got a B32 fuse(?). The wire, I have been told, is 10mm. Does the B32 have to be changed to a higher one, for example a B38, for the 8.5kw shower? I have been told it does by a sparky, but not sure if it is true, as there was previously a shower installed by the last tenants. I can put a plug on, I can wire a cooker up, so I'm sure I could do this shower myself as it's only Earth Neutral and Live. Is this sparky telling me the truth- do I really need a different fuse? Or is he just trying to get £50 out of me? I have no idea of the going rate, & this is cash in hand.

Thanks in advance

Could always rig up your shower to a beer keg lol Not sure you'll smell too nice though
