What companies other than BT and Virgin can connect a phone line in my home?
Any telephone provider has the ability to set up a line for you through openreach engineers which has part of a regulation made by ofcom BT had to give up the openreach brand and allow other companies access to the exchange. Companies like talk talk, sky and the post office are able to connect the line through openreach if they wish. But alot of these decide not to do it because it can be too much hassle for them. They rather tell customers to go to BT to connect the line and allow BT to tell the customer of the charge for connection.(makes BT look bad) unfortunately because it is openreach who connect the line not BT or Talk Talk etc openreach are the ones that charge you via the chosen service provider.
