its clear LRS days are numbered, even without ofcom intervening I believe LRS will disappear as the savings compared to normal line rental go down every year to a point the isp will say there is no longer a place for LRS.
Yes, it's disappearing because now they've all achieved this ridiculous setup where LR is really expensive and BB is really cheap, so they want you on both to make it viable (mostly for marketing purposes as it makes BB seem cheap and people resign themselves to LR in the end...) ... why would they then want to reduce the LR cash cow so that they make less - especially since the only possible sanity for it as it stands is that the discount is because they have less admin to do (less invoices to you, and so on) - but since almost everyone I know of still gets billed monthly for the Broadband, it's not even administratively beneficial to the ISP.
Since they've all made it harder to get a good overall price that is competitive even with the LR at full price, you'll bend over and take it.
What Ofcom should do is get shot of this artificial "cheap" broadband and spiralling Line Rental farce.
If it goes up much more it'll be at 50% gross margin for the LR component, which is ridiculous.
