Internal fire doors in a flat in a 3 storey building

[Guest Lynda]

Hi Our flat which is arranged over two floors  is on the top floor of a 3 storey purpose built block of 6 flats  which was  built in the 80s.  All the doors are self closing doors. We are renovating and have seen a door on eBay. Do all the doors need to be self closing including the bathroom and what standard should they be ?  Thanks

Current standards only require the front door to be self closing, it should also be to FD30s specification (a fire doorset of 30 minutes fire resistance and having intumescent seals and cold smoke brushes). Internal doors (except the bathroom) are usually FD20 doors (20 minutes fire resistance, often achieved using an FD30 door without seals)

Thanks for the helpful reply.
