How to tell if I got fire proof doors already installed?

Hi There,
I am having issue at this moment with my internal doors. Because I am doing loft conversion over third floor I am required to install fire proof doors everywhere in apartment. The thing is that my all doors got features required to claim that these doors are fire proof doors already because of 3 Hinges, door closers, they are not key operated lock and I guess all ironmongery on door are heat fire resistant up to 800 degree's. What missing is only intumescent strip which I can install myself easily.
I don't know if fire doors supposed to have some sort ident/certyfikation on it to say that they are fire proof or its based only on features which came with door?
Generally speaking I don't want to change them out because they are nice and new one will cost me about £1500.
Pictures attached. Any help or suggestions are appreciated. Thanks

By your description and photies it sounds like they likely already are, doors nowadays do have an sticker or similar to identify them as such http://www.firesafe.org.uk/html/fsequip/firedoor.htm (not sure when the stickers etc became mandatory tbh) but these are sometimes removed or planned off by the chippy. Present your argument to BC when they visit and I expect they'll be satisfied unless you get an idiot. Or have they already visited and questioned the fire doors?

Well, the glazed door is not a fire door

Typical fire doors will be 44mm thick as opposed to 34 for 'normal' doors, and they will be much heavier.

There may also be a coloured plastic plug on the hinge side, but not always

If you live in a flat. then you probably already have (or should have) fire doors to kitchen and lounge

No, BC he wasn't in my flat yet. After reading the guide linked by you its become rather obvious that attached non-glazed doors of mine are hollow core despite fact or 44 mm thickness and cannot be used. So intumescent strip won't help much in here and all that type of doors must be replaced (unless I am wrong?). Not too worry much; each cost about £150.
However glazed doors I am desperate to keep because of their price (new about £700 each).

Based on that link http://www.firesafe.org.uk/html/fsequip/firedoor.htm glazed door can be used as fire proof doors. The glass there need to be wired inside exactly as mine are. Also both of them are located in lounge and kitchen which point out that they might be fire proof doors anyway (is there any regulations which says that so I could based my argument with BC on?). Only intumescent strip is missing there. One thing which worries me is lack of intumescent strip between the glass and door itself as per guidance picture from the link above.
I don't really know how to approach BC with this.
Thanks

If you know how much the glazed doors cost, you should also know whether they are fire doors or not? Or did you not buy them yourself?

I did not see the GW from the thumbnail image

Yes fire doors can have glazing in, but typical SA pattern doors like that one may not meet fire door criteria as the glazing bars may not be thick enough to last in a fire. However, if the manufacturer has certified it, then that's OK

They wouldn't have put GW glazing in a non fire rated door. It sounds like you'd just be changing FDs for FDs...
