If your line is with sky on their llu then this will be why, you would first need to get the line returned onto the BTWLR3 platform before providers like plusnet are able to offer their broadband services, At the moment the BTW system can't see your line, so they cannot place an order with BT openreach, a way of testing this would be to enter you telephone number here,
https://www.btwholesale.com/includes/adsl/main.html And let us know what result it spits out back at you, If(MPF ) LLU then it won't recognise or be able to give any estimates ect, but will work if you use your address and post code
If you think about it, your line already is connected to a line card in the FTTC cab, a switch of ISP doesn't need more space to be available , infact a switch of ISP (FTTC >><<FTTC) doesn't require any changes to be made at the FTTC cab or at your home as that bit is already in place so will utilise the existing setup, except in the event that sky has supplied a combined fttc moden/router device, as that will be locked to sky, and you would then need a standard BT Openreach modem
