First floor door

Thank you for your reply. My buyers solicitor is still telling mine it doesn't meet requirements going from the FRA, I think the FRA is for the building in general as I don't think I've had a specific one done for my flat. I'm trying to contest but don't know how. Is there any information available regarding the law about the requirements you stated meaning it doesn't need one?

Hi, Apologies if this isn't posted in the correct place. I am currently selling my flat. It is a one bedroom ground floor in an old converted building with it's own entrance. My buyers solicitor is telling my solicitor I need to agree to install "an FD30S and provided with intumescent strips, cold smoke seals and a self-closing device, mounted on three fire rated BS 1935 hinges". My query is that my flat door does not connect to any common areas. It goes directly to the outside on the ground floor. There are no other flat entrance doors near mine. Is it a legal requirement to have my door changed before I can sell the property or not? I don't really want to spend a load of money I don't have to unless it's absolutely legally required. If it is then fair enough but none of the other flat doors with their own entrance have this. Just the common areas have proper fire doors from the hallways for the flats within the main block.
