I live in a rented room on the ground floor of a house. I have a fire door on my room which opens up into the kitchen. I then have to go through the hallway and another door to get to my front door. I have a large window in my room however this is blocked by a neighbours caravan which is parked on their driveway which happens to be by the side of the house. I cannot open the window more than a few inches and definitely would not be able to escape via the window if there was a fire in the kitchen. 

Do I need to report this to my landlord - if so is there anything we can do about the caravan parked outside even though it is on the neighbours property? Does my landlord need to provide me with a fire escape window as I am on the ground floor? Any advice will be greatly appreciated. 

Do you rent the room as a lodger and if so how many lodgers are there or is it a house converted into flats.
