Do I have to contribute to the upgrade of my aerial system when I already have digital TV via another means?
It depends on what your lease or tenancy agreement says on whether you will have to contribute to the upgrade and maintenance of the communal TV system. As part of the structure of the building it is likely that the landlord will be entitled to recover the cost of an upgrade from residents. The landlord will be looking at the long term lettability of the property and will expect that all dwellings will be connected to the system. It will also give you the flexibility should you decide in the future to change your platform provider.
