fd30 external fire doors - can you advise?

[MizzyMe]

Hi,

Can anyone assist with external fd30 fire doors? I have been searching for a company that does fitting of fire doors but it has been a challenge, either they don't do fire doors or they do not have the required certification to do them or they do not have the design we require. It really has been a challenge.

We would like a fd30 4-square glaze external door with fitting of frame and top window. Does anyone have any advice?

We live in a flat, end of balcony so if we had a fire no resident would need to pass us for the stairwell. The question here is "do we really need a fire door?"
