Moving external phone line

[Fionas16]

I am looking at getting the external phone line into my house moved roughly 12" lower as it currently goes through my fascias/sofits and they are being replaced soon. I have been advised that I need to contact BT/Sky/Openreach. Do I contact  openreach directly or do I need to go through sky as my contract is with sky for superfast broadband and pay as you talk calls. (Im not even sure I need the phone line for what Sky provides)

It's Sky you need to contact. They'll liaise with Openreach. Your broadband service is delivered via the phone line, unless you have a separate fibre optical cable to your home.

Hi @Mark39 thank you for your response. No I dont have a seperate fibre optical cable. 

So im guessing I will have to call the general customer service line or is there an option of a chat service with Sky?
