Thanks very much for all of the replies. so the update is i have managed to obtain the fire safety certificate from them, which says that the door fully complies with Q mark fire door installation scheme and with building regulations 4 and 7, and it has the BM trada logo at the top.
I can't see any certification stickers or marks on the door or frame however.
I was aware of the regulations regarding maximum gap between door and frame, however this gap is between the frame and the wall and like can't find any guidance online about whether that is acceptable or not
regarding fire rated sealant there is no sealant sealing the visible gap between frame and walll, however actually inside the wall you can see they have used some kind of blue sealant
perhaps Mike's idea off having a chat with the local fire brigade is a good idea to see whether this is really OK from a legal standpoint
Anthony what kind of product do you think they should have used to seal the gap between frame and wall?
Even if the door is OK from a legal fire safety point of view, does this seem like a reasonable job and workmanship just aesthetically? i can understand that they are saying that decorating is not part of their job, but should they not have at least made the door to fit better or at least filled that gap in themselves somehow?
i am concerned that even if the door does pass certification and is compliant , it's poor aesthetics will affect the value of my property. i am worried that even when that gap is filled with some kind of sealant it will look shoddy
