The government has promised consumers a guaranteed minimum broadband speed of at least 2MBs.
Communications minister Stephen Timms said that the 2MBs universal broadband service proposed in the Digital Britain report was for a guaranteed minimum network speed delivered to consumers.
His promise goes further than Digital Britain report which spoke of an "up to 2MBs" service.
Timms was speaking at packed meeting of the All Party Parliamentary Committee on Communications (apComms).
Derek Wyatt chairman of the telecoms watchdog, OFCOM, welcomed the minister's statement.
"I am encouraged by the minister being brave enough to guarantee two megabits," he said.
Officials at the Department of Business Innovation and Skills had said earlier that 2MBs was 'indicative' rather than guaranteed.
Andy Carter from the Department of Business Innovation and Skills said 11% of telephone lines in the UK could not get broadband, but this could be overcome using BT's 21CN technology, line conditioning equipment, and other means to improve signal quality.
He said the proposed £6 a year levy would go to improve access to higher speed networks mainly in urban areas.
