Hi, Hope you can advise?

We are currently expanding and moving the office around as a result. We currently have 2 means of access on the first floor and in the design it proposes to take this away does this pose a fire safety issue? the only route would then be down a protected stair well. 

Everything I am reading suggest we would need 2 fire escapes overall which we do have on the ground floor.

It is impossible to give you an answer with the details you have provided, it could be acceptable on the other hand it may not be acceptable. I would need the answers to many more questions, like the layout, travel distances and others, so I would suggest you employ the services of a fire safety consultant to look at your proposals.
