So took advantage of the Ultimate package.
Have broadband issues, but that is on another post.
1st TV - upgraded box and all working as expected.
Was advised when I ordered that I do not need an engineer to install 2nd box.
Well, not sure how that works, as it needs cabling back to the main junction box thingie......
And there seems to be no way to book one, so not what what to do or how to get it working ?
