The winners of the TalkTalk Digital Heroes Awards will each receive £5,000 funding for their projects, which have helped bring positive social change. One of the 12 will be named 'Overall Winner' and receive a grand prize of £10,000. Each of the winner will also be entitled to free broadband for 18 months from the ISP.
TalkTalk's chairman Charles Dunstone will be joined on the judging panel by UK Digital Champion, Martha Lane-Fox, and editor of the Daily Mirror, Richard Wallace.
"Hidden away across the UK in charities and local community groups are countless unsung digital heroes who recognise the positive impact the internet can have on everyday people's lives," said TalkTalk's chairman Charles Dunstone.
"The TalkTalk Digital Heroes Awards are our way of rewarding the hard work of individuals who are using digital technology to make Britain a better place to live."
Brits have until September 20 to enter the Digital Heroes Awards. For more information, visit TalkTalk's dedicated web page.
