Around 6 million carers could benefit from a new bill that received its second reading in Parliament on Friday.
The Carers (Equal Opportunities) Bill, which has cross-party support, would put the social services under an obligation to inform carers about their rights and opportunities in training and employment.
Carers UK, Help the Aged and the National Autistic Society are among the charities supporting the private member's bill, which was proposed by Labour MP Dr Hywel Francis.
Baroness Jill Pitkeathley, the former chief executive of Carers UK who is championing the Bill, is confident it will become law. "It's another important step forward for carers in helping them have an ordinary life," she said.
