The Communications Minister has welcomed BT's new Race to Infinity initiative, which aims to identify areas of high demand for super-fast broadband.
Up until the end of 2010, BT is conducting a survey of the UK to help assess community needs and guide future fibre-optic broadband deployments.
Consumers, businesses and local communities can register their interest in BT Infinity, with the five areas seeing the highest levels of demand being guaranteed a network connection by 2012.
According to BT, this could see commercially-viable exchanges "brought forward to the front of the queue", or non-viable exchanges added to the firm's deployment plans.
Communications Minister Ed Vaizey commented: "Whenever I travel around the UK I hear the same message: people want access to superfast broadband in their communities.
"I warmly welcome any initiative that will lead to private sector investment in fibre networks, and applaud the way BT are engaging consumers to ensure that investment reaches the people who want it the most."
BT is currently investing £2.5 billion upgrading its national broadband infrastructure, enabling consumers and businesses to receive faster download speeds.
