In a block of flats where the flat entrance doors all open onto a single escape staircase, where one of the residents (who owns their own flat) refuses to replace the UPVC door they have installed themselves (!!!) what actions can we / landlord take to make them replace this??
Plus, are all the doors opening onto the staircase from flat entrances down to the landlord now (taking into account the new Fire Safety Act and Building Safety Act) and not the residents / tenants??
Anyone who can throw any light or specific legislation my way would be my new best friend as they are causing me a severe headache!

Thanks as always to all that can help.
