: What about using one of those cheap timers used to keep a bathroom
extractor
: fan running for a few minutes after the light is switched off?

I'm not sure I've even seen something dedicated to that. Are those
wind up timer switches on a lightswitch panel?

No, its an electronic add-on to a bathroom extractor

Light turned on = fan starts running
Light turned off = fan continues running for a per-determined period then
shuts off
