Just Ofcom getting it wrong, again. I'd rather know which ISP wants to rip me off most with line rental. Openreach charge them at most £7.23 per month, plus Vat would be £8.67 compared with what we are charged.
Isn't it at
least that cost since some providers, inc BT, pay more for premium line rental or maintenance options. I would suggest that most people want to know the total price and make a value judgement based on the whole. To only focus on gross profit of line rental and ignore the rest is a bit... eccentric. As you yourself point out, the margins are not spread linearly across the components, hence the crazy prices on LR both ways.... so where's the logic in your method?
I pay £13pm line rental, plus £1pm for caller display. 1471 and 1571 are included.
A very good reading on the Roberto-o-meter. How much do you pay for your broadband, must be cheap as chips?
