Just as a follow on point, I hope VM wont have the cheek to charge me for extending the co axial cable in the lounge !!, as it wasn't fit for purpose when installed ,and as the VM video says you need at least a metre clearance and with no cable it is stuck between the TV and chimney breast
As long as you don't tell them about it, they don't care! A lot of people replace the coax cable.
Some goodie two shoes may tell you that not using VM's super duper cables could induce noise in the system that will propagate to other homes; true if it's a badly made cable. But respectable cable makes are fine.
