Hi

We own a  a one bedroom retirement flat which has entrance hall.

We want to replace four interior doors in the hall. 2 are fire doors.

Is it necessary to replace the fire doors with the same  ?

According to ADB all doors in a domestic property should be FD20 fire doors, but very few manufacturers test to the FD20 standard, they use FD30 fire doors instead and it is consider substantial  well fitting existing doors meet the FD20 standard. Because you are fitting new doors they should be FD20/30 doors
