You need one with a timed overrun. Very common.

Also any ideas on what rating i need

If there's no wiring present for the fan then you'll also find details of how to connect it in the Wiki, don't forget you should also install a 3-pole fan isolator, and you should read these:

• IEE article
  
  
• Wiring Regulations requirements for concealed cables
  
  
• Wiring Regulations requirements for bathroom circuits

And if you're in England or Wales you should also read this:

Tell him that as you expect him to guarantee the job he'd better supply the fan to avoid any arguments.

It might.

It might not.

It might do it for a while and then pack up.

It might keep going for years.

But as with most things it's probably best to avoid products made by people you've never heard of and sold cheap on eBay, and stick with products made by well established names.

What about ip ratings which is better?

IP ratings are nothing to do with performance

By looking at the specs for how much air they shift and picking the one that shifts the most.
