Older loft conversion sales query

[Kickstart]

We have a Victorian terrace that we are about to sell which has a converted loft which was done in the 1960's - it is not done to modern building regs (ceiling height slightly too low and no fire doors) - some of the agents we have had to look at it say its fine to list as 3 bed but explain the position and others say can only be listed as 2 bed with attic room

Does anyone know the correct answer

many thanks

Why would anyone expect a conversion done 60 years ago to meet modern regs? Or is that just me who thinks that.

But just list like the agents say they probably know best as it's their job.
