A BT spokesperson said: "Most communications providers have already completed or are nearing the end of migrating their customers across to the next generation network. That network currently reaches 92 per cent of UK premises whilst the remainder of premises will be unaffected as legacy broadband services will be maintained in these areas.
"We are working closely with industry to ensure the smooth migration of any remaining end customers onto our next generation network. There is still plenty of time for end customers to migrate as we will continue to maintain the legacy broadband network until the end of September 2014. We would urge communications providers to migrate their customers onto the next generation network by the end of June 2014 however, and to contact us should they experience any problems."
BT turned off its dial-up service last September, leaving a number of customers in rural locations without an internet connection.
