Check that fire doors are certified and intact using this short 5-step process:
Check the top or the side of the door for a certification sticker. This should tell you which fire rating the door is certified to.
Use a £1 coin to check the gaps around the top and sides of the door. There should be a 4mm gap, so if checking with £1 coin there should be 1mm of room left to spare. If there's more than this the door may not work as desired.
Are the seals around the door or door frame intact? If they're hanging off or seem loose then the door may be damaged.
Are the hinges tight and firm? If they're loose or wobbling then the door hasn't been maintained.
Open the door and let it close from halfway by itself – does it shut properly? If so it's in good order.
