9.5 KW should be ok.
A 32 amp circuit breaker is inadequate for any shower rated over 7 kilowatts.

If you want a 9.5kW shower, you need a 45 amp circuit breaker at the consumer unit ( a.k.a. ‘fuse board’). You also need 16mm cable between the consumer unit and the shower. If the circuit you’re using presently has a 32 amp circuit breaker, then the likelihood is the cable from it to the bathroom is only 6mm. This is completely inadequate and requires an electrician to remove and replace it.

A 9.5kW electric shower is ‘OK’ but that’s all. Seeing as you are going to have to have to have a professional installation done, including work to your house’s wiring and main fuses, you might as well have it all up-rated for a more powerful shower which will be much nicer to use. Go for 11 or 12 kW if you can.
