Virgin Media have make own coax cabling that can't be bought from a store, so you'd have to pay the callout fee of £99 to get the kit relocated.
+Add: Any move greater than 5 meters will require attenuators etc etc. Using random coax cables from a store will knock your connection offline and all the people in your part of the network will be taken offline too by a SNR fault. Which would result in your property being cut off and you being charged.
