If you're moving home then you shouldn't have to leave Freeview behind, 

First check to see what kind of Freeview service you can get at your new location by running the address through this too here https://www.freeviewnz.tv/get-freeview/get-freeview/coverage-check/

Simply take your box and any connections with you and, if your new home has an existing satellite dish / UHF aerial you should be able to connect straight to it.

If you need to arrange for a aerial to be installed in the new house, or if you experience any issues using your existing equipment with the new dish please contact your local installer.
