Fitting a wall mounted extractor fan in bathroom, the bathroom has a flat roof so was wondering if i can wire the fan to anywhere other than the bathroom light fitting, ie the light fitting for the room below, if so i take it i won't be able to use a timed fan due to timer run off light switch, would an auto fan be better or just a simple pull cord.

The fan needs to be added to the ceiling lighting circuit if you want the unit to work in tandem with the light on / off (and or a timer).
If you go via the downstairs lighting circuit you will have no choice but to have a stand alone fan. With the circuit being down stairs your need to isolate the fan for servicing and repair with a fused spur, so you have an on / off point.
If you want a fan with additional controls such as pull cord, sensor, sensor with overrun timer then that's a simple matter of choice.
If this work is part of a conversion with Council inspection they tend to insist on fans with over run and 'x' m cubed extraction rates.
As I'm sure you know, wet area work has requirements regarding IP ratings for fittings, zone conditions and notification.

They can 'tend to insist' all they like.
An over run timer is only required if the (bath) room does not have an opening window.
