Thanks for getting in touch.
I'm happy to advise you as I appreciate your concerns about switching from Virgin Media.
If there is no BT line then the standard installation charge is £49.99. Any issue with the line in future should be reported to us, we will liaise with our suppliers Openreach who would identify or fix any faults. Fault diagnosis is thorough and is done using Openreach systems, you would not pay for faults to be fixed if they were infrastructure related.
I trust this is of help, if you have any questions you can come back to us or you can contact our Sales Team directly on 0800 432 0080 between the following hours:
08:00 to 20:00 (Monday to Friday)
09:00 to 19:00 (Saturday)
09:00 to 18:00 (Sunday)
Call wait times to our Residential Sales Team are minimal, although peak times do affect the time you have to wait.
Let us know if you need anything further.
Thanks - LF
