Extractor fan with pir wiring question

[Trickydicky]

Hi all,
I intend to fit a extractor fan with built in pir sensor in my downstairs wc.
My question is regarding the wiring , could I take power from my ceiling rose to an isolator then from the isolator straight to the fan avoiding the light switch , as the sensor would turn the fan on ...any advice would be greatly appreciated on the correct way to do this.

No reason not to, providing you have a PL at the rose. If not then the fan will only work when the light is on.
