It sounds that you need a fan to meet building regs. But if you are fitting
one then it must ventilate to outside and not into the loft.

Indeed. Venting steam into a loft with cold surfaces and timbers[1] is worse
than leaving the steam in the bathroom.

[1] In winter, it will condense, be loath to dry out and cause rot.

I was just thinking that, I have no fan, but from experience of a neighbours
one that does go to the loft, a alot of dust comes in that way and it all
sticks to the paint and tiles after a while, and probably wet bodies as
well!

Ours vents through trunking in the loft and out via the soffit. No
non-return flap so occasionally we get a draught down from it and a
little of our dust back.

If it's vented outdoors, and you don't live in Avonmouth, then it shouldn't be catching dust. Check that the flexi hose inside the loft isn't torn.

There should also be a non-return flap valve, because the wind will try to blow back down it at times. If this is mounted on the soffit at the exhaust fitting, and you're still getting dust, then that really does suggest a torn pipe in the loft.

As long as the local birds cannot get in that way of course!

Luckily its not mine...
My bathroom is quite old and still has just an air brick.

There is a grille at the exit through the soffit. Hopefully the local
mice will not chew through the trunking!
