I have a bit of a problem. I rent a house from a charity. They are all lovely people and I know the charity needs the rental income to survive. Unfortunately they don't seem to have anyone advising them on the legal side of being landlords. I'm currently trying to sort out an ongoing issue with my garden. A fence and gate has been erected to give privacy from another building that is used by the public, which has access from the front now. The tenancy agreement originally gave access through the garden at the back of the building, for the purpose of accessing a storage area. This storage no longer exists. I'm now being told by one of the individuals connected with the charity that I cannot store anything in front of the gate. I've checked on this and it seems that the change of use voids the access clause as the purpose no longer exists. My question is how do I go about telling them that they are behaving illegally without upsetting anyone or causing more conflict? My useable garden space is half the size it was when I moved in and I should be able to use all the space I am paying for. I have already been very understanding over a separate issue that means I lose some of my garden at the end as well so I do feel this is taking the mickey. I want to solve this without legal action if possible. To complicate matters I know they won't be able to re-let the property if I just move because it doesn't have a low enough EPC rating. Help!
