How do I know if my door is a fire door?
Get a priceLook at the top edge of the door. A certified fire door usually has a label or a small coloured plug there, showing who made it and who certified it.
If you can see one, you have somewhere to start.

Other clues
Look at the edge of the door or the frame for a strip running all the way up. This is usually the intumescent strip, and sometimes it has a brush or fin as well for smoke.
Glass in a fire door should have a small mark etched in the corner showing it is fire rated.
Fire doors are heavy. They also usually have a closer on the top.
What does not tell you anything
A sign saying "Fire Door Keep Shut" proves nothing. Anyone can stick that on.
Being thick and heavy proves nothing either. Plenty of solid doors were never tested.
Old paperwork helps but only if you can tie it to the door in front of you.
If you still cannot tell
Plenty of older doors have no marking at all. It does not automatically mean they are useless, but it does mean you cannot prove what they are.
