By 'aerial', do you mean the coax lead from the Virgin broadband Hub? If so, you can book with Customer Support for a technician visit to move the cables where you want them. There is a standard charge of £25.
Do you mean the Virgin Media connection? If so, as jpeg1 has said, we'll be happy to help send a technician visit and there is a cost of £25 for this service.
We can check availability for you Amylouise1990, I will send you a Private message to get some more details to help arrange this and look forward to hearing back form you 🙂
