The people making them have now said I need trickle vents - but do I.

If you spec windows with two stage locks that allow them to be "closed"
but still slightly ajar then you won't need separate vents.

(I know this, because I speced trickel vents on the windows, showed them
to the BCO along with the two stage opening, and he said that they would
have been happy with the openers alone!)
