TalkTalk has warned that up to a third of people in the UK will be left without superfast broadband unless the government and Ofcom act.
According to a report commissioned by the Salford-headquartered company, one quarter of the population will still be on slower internet connections on copper networks by 2030.
It added that people are hesitant to switch providers to new ultrafast fibre optic broadband because of what they see as negligible benefits. The report also says consumers worry it could cause them internet problems in the short term and that they do not want to pay more.
