I'm just about to have some (wooden) double glazing installed and the installer has advised me that trickle/night vents aren't really necessary and that the windows can be left slightly and securely open to have the same effect. He also says that they are very ugly.

They have advised that I can have them if I want, but I don't really need to bother.

Are they essential, or can I manage without them?

They are not required if the window can be locked in a trickle
ventilation mode. My window installer said most private properties
don't have them installed, but councils usually require them in
council properties. He also always advised fitting them in rented
out properties, where the non-owner residents often think nothing
of leaving wet washing out to dry with all the windows shut, and
then complain to the landlord of condensation/mold.

Some ventilation is necessary especially in kitchens and Bathrooms. Also
all over the house in hot weather.

My double glazed units have two locked positions, one no ventilation and
another *locked* about 1/2 ins open. In winter I put a bit of 1/2 ins
square wood on the open side of the window to reduce the ventilation the
about 2 sq ins per window.
