The admission will not surprise those who remember what a difficult summer Labour had.
Even a number of the party's own MPs publicly admitted they did not know where it stood on a range of key issues such as welfare, education and health.
Mr Miliband has in many ways answered those calls.
In the pledge that his post 2015 government would freeze gas and electricity bills for two years he has delivered that most rare of political animals - a popular easily understood policy.
Labour strategists believe that he has also successfully killed the larger narrative that no-one knows what Ed Miliband stands for.
And they feel that he has staked out his territory as the political leader on the side of ordinary people, willing to help them stand up to big business.
Other questions still remain, however.
A handful of eye catching policies do not make a manifesto.
Labour still has a lot of issues it is considering in its policy review, likened by one former Labour minister this week to the Edinburgh panda pregnancy for promising much and so far delivering little.
Many of the proposals that were outlined at this conference will require a lot more detail before they can be put to the public prior to the next general election.
For example Mr Miliband has said that he backs an idea to combine health and social care.
But there is little information about how it might work in practise and crucially how expensive it might be, at least in the short term to get it up and running.
Battle is also continuing to rage between Labour and the energy companies over its bills plan, a row that will undoubtedly run and run.
There was a certain nervousness about the party yesterday, suggesting that the scheme had not exactly had the reception it expected.
But Labour sources insist the policy is robust and say they have been working on it behind the scenes "for months".
Miliband's final lingering problem are the questions over his leadership, with opinion polls suggesting that much of the public still do not view him as a future Prime Minister.
To counter that image he attacked David Cameron as weak and challenged the Tory leader to a contest over leadership. But his real fight could still be with the energy companies.
If so, having staked so much on what Labour clearly hopes will be a 'game changer' policy, it will be a fight he needs to win.
