If you want to move the VM equipment then there is a standard charge of £99 to do this (extend using the correct triple screened cable, plus adjustment of the signal levels).
If you can leave the VM equipment where it is & use a long HDMI cable (ie. Just move the TV) you will find it far cheaper. Virgins cable is specially made for their service use, so DIY extensions are not an option.
