Telecoms as in broadband or mobile phones? Because BT were capable of rolling out fibre direct to houses at low cost (due to economies of scale) in the 90s if they hadn’t been broken up by the Tories (Thatcher).
More mobile than fixed services, although fixed line broadband will be redundant in 5-10 years as 5G becomes more common place.
Absolutely not. It’s been a car crash that’s seen rampant profiteering and us left behind in both broadband speed and cell phone coverage.
We have some of the lowest costs and most competitive markets in Europe, you could make a strong argument that privatisation has benefitted consumers. Coverage wise, certainly in rural areas, has been a failure but that’s firmly with the regulator not driving for coverage but more about speed.
