New bathroom fan issue

Recently the extractor fan in my bathroom stopped working properly after more than 10 years (it was making a whining noise/sounded like it was wearing out) so I bought exactly the same model to replace it.

I swapped the fans over - putting the live and neutral wires in the same terminals as the previous fan. However when I turned the power on the fan did not work. I thought that the new fan may be faulty so I took it back and got a replacement (same model). The same thing happened - no power. I ended up exchanging the fan 3 more times (the last time I bought a different model), but the same thing happens each time.

I have tried attaching a standard light bulb to the wires which works OK, (see pic).

The models of the fans i have tried are: <>

and <>

Any help would be appeciated.

Did your original fan have a timer ,so it would continue to run for a while after you switched it off ?
Your pic appears to show only two conductors ( live and neutral ) ,and the fans linked are fans with timers ,that would need 3 conductors , permanent live ,neutral and switched live.
The old fan had the option of bypassing the timer (which I did), so I was only using the same two wires you can see in the pic.
