Presenter Emily Maitlis and pollster Peter Kellner will look at the seat by seat detail of how Britain has voted, and Fiona Bruce will provide regular news updates.
James Naughtie and Carolyn Quinn will present Radio 4's Election Special.
The election will also be covered on CBBC's Newsround and Radio 1's Newsbeat which will debate issues that matter to younger audiences.
There will be extensive coverage online, and across England there will be regional television and local radio station debates. The BBC will hold party leader election debates in Scotland, Wales and Northern Ireland.
Helen Boaden, director of BBC News, said: “With the polls indicating this could be the closest election in decades, the BBC's coverage will be vital in helping the public compare and analyse the policies and choices provided by the parties and candidates standing for election.
“Our coverage will be clear, authoritative and, most importantly, impartial.”</>
