BT Openreach is launching a 110Mbps fibre to the premises (FTTP) service, which it claims will provide downstream speeds of up to 300Mbps from 2012.
BT Openreach also plans to double the speeds delivered by fibre to the cabinet (FTTC) broadband from 40Mbps to 80Mbps.
BT is investing £2.5bn to make fibre broadband available to two-thirds of UK premises by the end of 2015. However, as Computer Weekly has previously reported, large areas of rural Britain are being left behind, with operators unable to justify making large investments.
Communications Minister Ed Vaizey said: "These are significant announcements and good news for the UK. High-speed broadband is essential for economic growth, which is why we want the UK to have the best superfast broadband in Europe by 2015.
Openreach is now offering its FTTP service on a commercial basis. From late October, Ashford in Middlesex, Bradwell Abbey in Milton Keynes, Highams Park in North London, Chester South, St Austell and York will have access to this service. BT said FTTP will be available to communications providers to use on an equivalent and wholesale basis, allowing them to market the service to users.
According to BT, the fastest speed combinations being made available this month are 110/15 and 100/30, but speeds of up to 300Mbps will be available from next spring.
