Hello, 

Last year I purchased a second floor apartment which was purpose built in 2003.  The main door from the communal area into the apartment is a fire door with multipoint locking system. The springs in the door mechanism are no longer working and so I was looking to replace either the gearbox within it, or the old unsprung door handles with new sprung ones. As this is a fire door, am I right in thinking that all the fittings also have to be fire rated as I am unable to find any that are. Thanks

 

Yes that's right you should first check the existing lock-set is suitable for your fire resisting door and, if so, then replace like for like. If in doubt contact the fire door manufacturer (if known) or a fire door specialist.
