My Girlfriend has moved in as a lodger to a 2 bed house where the owner (who no doubt cannot afford the mortgage) has just landed her with a tenancy agreement (not license which I thought was standard for lodgers). Part of the terms of this is that should my girlfriend move out she has to find a new occupant for her room. Can the landlady do this or is this a clause that has no backup under case law/statutory law?
A little background. My GF pays half the bills yet the landlady runs her film production company (
) from an office there, using up way more than half the electricity. Also the GF is not on the council tax bill at this new residence and as such I cannot remove her from my own.Anyone on here offer any assistance?

ouch.... I think I cracked a rib.
