Wiring Advice

hi All,
I need to replace a bathroom ceiling extractor fan (centrifugal) in an apt. Unfortunately, the existing cabling is too short to wire the new fan I've bought.
Just wondering what the best approach to this would be. I was thinking of putting in some form of junction box in the ceiling space beside the fan, and then connecting that to the fan.
I've only wired plugs, sockets and light fittings before so not sure if it would be better to get an electrician in.
Am I underestimating what needs to be done e.g. should completly new cabling be run? As it's in the ceiling I reckon running new cabling would be very expensive.

Its only for a ceiling fan, so the load on the circuit wouldn't be that great. If you get a junction box rated for 10A it should be ok. Do you know where the power for the fan is being fed from?

thanks Fingers McGee, I might give the junction box a go and see how I get on.
I cant see the origin of the cables. Looks like I'd have to punch a big hole in the ceiling to even get an idea. So, I'm not too eager to go down that route.

Would they be looped to the light fitting by any chance?

Yep, it's connected to the light somehow.
Turning on the light also turns on the fan. Will this make a difference?

No, but if it was linked from the light fitting, perhaps you could replace that short bit of cable rather than using a jb. Thats if things actually transpire in the right way of course
