I didn't bother specifying trickle vents for the window I've just ordered.

Never been totally sure why there is an obsession with them. Room in
question has a chimney vent which will allow some air and the house has
tones of fixed ventilation and plenty of leaky doors.

If that's not enough, the top transoms can be safely locked an inch open
anyway[1], which is a good as a trickle vent which may be closed (at least
on the last window I got where I didn't think not to specify them).

[1] This is more visible to check anyway.
