    Just had a heated discussion with a building inspector about final exit doors in a small block of flats that I have been helping with. I specified one handed egress, thus there is a sash lock with a Euro cylinder on the front door of the flat, key on the outside and thumb turn inside but crucially when locked no one can get in from outside without a key but from inside by depressing the lever handle a person carrying a child or assisting an elderly person can get out with one hand easily, quickly and safely; the lever itself retracts the deadbolt and the latch in a single operation.

    The inspector has insisted we fit an additional deadlock! (Required by partQ) we intend to throw away the keys!

    You don't give enough information to know what is required (position of windows and alternate access etc) but part Q does not always require keys on both sides. I suggest finding a locksmith who does understand the requirements and using his expertise to outface the building inspector.

    He was not asking for keys inside just a second deadlock (with thumbturn inside)

    Gf, 1st and second floor flats, only one way out via common stairs apart from sliding sash windows with security stops at 100mm open.

    Then I don't understand your problem. It's very easy to operate two thumbturns with one hand - just do one after the other.

    Was his problem then that the lock you specified was not multipoint? I can see how that might cause problems.
