Vents as opposed to the natural gap under the door? Personally I wasn't
going to bother - the doors on mine will be leaky enough without any extra
help.

I had assumed gaps under doors would be sufficient. Its a bit weird
with a toilet, as noise insulation regs and trickle vent regs are in
conflict.
I'll put some general statement on the spec as "blah blah will be
provided", and then do nothing and see if BCO says anything. I wonder
it trickle vent could be supplied via the extractor fan route. I
reckon there would be some leakage there anyway, surely ?
