If the tree is a deciduous tree and does not hang over the boundary and trespass onto your property, or it is actually on the property but simply prevents you getting a television signal, I’m sorry to have to say that there is nothing you can do about it.
If it’s in a neighbouring property you can cut overhanging branches off and return them to the neighbour and seek the cost of it from the neighbour.
You cannot cut random branches off to get a television signal.
If the tree is in your garden and belongs to your landlord and he simply doesn’t want to do anything about it, that you can’t do anything about it unless he promised, before you went into the property, that he would do this in order for you to get a television signal.
You have a remedy with regard to the tree if it is generally a nuisance but not because you can’t get a television signal. There is already caselaw on this which you will read from this link.
I’m sorry I wish I could give you a better answer. Can I clarify anything for you?
Please don’t forget to rate the service positive. It’s an important part of the process by which experts get paid.
