What I would do is instead of just running T&E to the switch, I'd run three core and earth, then of your three cores, one is the permanent live, one is the switched live for the light, and one is the switched live for the fan. Your junction box would be 'interesting' due to the amount of connections (it may be easier to put in a larger adaptable box or similar), but essentially you then wire it as you have done, except take a feed to the fan from the neutral, earth, and new switched live from the switch.
In the switch you'd also need a small bit of wire linking the two switches together so they both had the permanent live...
"Give a man a fish...."Is it so difficult to just say this wire goes here and that wire goes there, connect this to that etc..
But similar enough for you to be able to work out how to do what you want...I have re-read the documents and links you posted. But as you can see my application/situation is slightly different to the examples documented.
Yup - apart from the circuit earth & neutral which you spotted.Okay ban-all-sheds, I have read and re-read and re-read the notes and links which you posted, i think i could wire the three downlights to the switch as follows:-

Let me know what you think / if this is correct.
Why do you think circuits have neutral conductors?Thanks Rebuke, I was thinking of wiring the fan in like this:

Is this correct? will it work?
Looks good to me, only things I can see missing are the brown sleeving on the switched live to the fan (as you've already spotted), also some blue sleeving on both ends of the yellow neutral in the 3-core to the fan (or should it be black sleeving as that's an old colours cable - I'm not sure...). There should also be an earth connection between the switch (or at least the back box if no terminal on the switch) and the other earths. If it's a plastic fronted switch and back box with no earth terminals, then just put it in a bit of choc block at the switch end.
You appear to have ended up on your diagram with a very strange set of colours on the cable to the fan - it's presumably either old colours (red/yellow/blue), or new colours (brown/black/grey), but you seem to have brown/yellow/grey?
Black is no longer the colour for neutral, it's one of the phase colours (was yellow/L2), so using it will not indicate that that conductor is neutral - you must not mix'n'match - either stick to Red/Yellow/Blue/Black or Brown/Black/Grey/Blue, but not a made-up hybrid.Red (perm live - now brown)
Blue (switched live - now grey)
Solid yellow (neutral - now black)
Yellow & Green (earth)
