Fire doors in a bungalow with a loft conversion?

[steviejasp]

I can't seem to find a definitive answer to this.
It seems that they aren't needed as long as first floor windows open wide enough to escape.
We were told that we would need them as there is a full width conservatory on the back which wouldn't allow escape in the event of a fire.
Anybody know for sure?

Thanks chaps. So even with the conservatory, we don't need fire doors?

There is a dorma on the front as well with escapable windows. Would that be enough to satisfy BC?

two bedrooms and a bathroom upstairs

Thanks everybody for the input, I'll let you know how it pans out..
