I'm moving to a new home and would like to take my broadband with me. The problem I have is the new house already has internet there, which has a really bad internet speed and the owner won't upgrade or cancel. So would it be possible to have both, mine and the owners broadband in the same house and I just unplug the owners.
It is possible to have more than one line in a house with the same or another supplier.
However the second line would have to be installed etc. You need to check first with the current owner - check Ts&Cs of your contract with them for what is allowed.
