My scond post with what maybe an unusual scenerio....
I live in  a 3 roomed HMO with a lounge, kitchen & bathroom meant to be communal.  Presently, I am having a dispute with the landlord over an issue of a broken lock (my first post here).
As a result, I took a closer look at my lease which is an individual AST lease.  I noticed that under "property details" instead of saying I rent room 1,2, 3 etc, or front room back, basement room, It simply states that I rent the property.  The next clause is about exclusions, and they are simply, the other 2 rooms in the property & the attic as the landlord has goods stored there.
One tenant moved out and the other tenant moved to the property from another of the landlords property's and she doesn't have a lease for this address.  With this in mind (I know the reality but just for sake of debate), since the lease says I rent the whole property, with the noted exclusions, would it be fair to say that the landlord would not have any right to the communal areas of the property with giving me at least 24hr notice ?  Also, since I rent the property, how could the landlord rent out the other 2 rooms without me granting access through  the rest of the property in order for new tenants to get into their room ?
Could I charge a fee for this or charge for the tenants to have access to what would ordinarily be "communal" ?
Quite interesting I thought, obviously wouldn't push it but does anyone have any thoughts on this scenerio.  bare in mind, since noone else in property has a lease, IAM the only tenant that has a lease for the property......
Just asking for thoughts, humorous or others
