Leader Ed Miliband will use a speech to tell voters his party offers a "positive" vision to counter the "threat" of another five years of Conservative rule.
Labour faced a difficult summer last year amid accusations the party was too quiet and complaints from some of its own MPs about a lack of policies.
The party has promised this year will be different, with a blitz of speeches and announcements designed to win over voters.
Mr Miliband will use a speech in London today to underline his fear that by this time next year the Conservatives could have secured another term in office.
He is expected to say the choice for voters is between "the threat of another five years of David Cameron and a second-term Tory Government (and) ... the positive vision for the future of Labour".
He will say it is: "A choice between a Labour Government that will build our country so it works for ordinary families once again or a Tory Government that will look after only the few.
"A choice between a Labour Government determined to change an economy that doesn't work for most people or a Tory Government that thinks everything is fixed.
"A choice between a Labour Government that believes the way a country succeeds is with the talents of all or a Tory Government that thinks the only people who create wealth are those at the top."
Last year the Labour leader faced accusations of a "summer of silence" as he was urged to tell voters what a potential Labour Government would offer in terms of policy. His detractors complained Mr Miliband was leaving the field open to a pro-active Tory campaign machine.
'New Labour, new danger' was a slogan used by the Conservatives before the 1997 General Election. An advertising campaign with the phrase was devised by Saatchi & Saatchi.
