I will let you judge whether that key info should be in the public section or not
As regards the wafer locks, its a differant profile normally for each manufacturer so its not really that quite as bad,
Unfortunatley on new builds it is the norm i think but i wouldnt have upvc and much favour wood,
The handles are on the inside of the window, the lock stops the handle moveing, nothing more, easily forced,
The locks are on the inside just like every other locking thing in the world, if the lock was on the outside it would be a handle and not a lock
Real window locks arent much better though to be honest with a lot of them just being a thumb turn your screw down
