'We want the public to tell us how they think we should be delivering decent retirement incomes to pensioners in the future,' said a DWP spokesman.
The public will be encouraged to join in the debate at events and online, said Opinion Leader joint CEO Deborah Mattinson.
Parties such as the CBI, charities and the pensions industry itself will be urged to manage further consultation events with help from the researcher. The findings of the programme will contribute towards a white paper later in the year.
A focus of the consultation will be the contents of last November's Pension Commission report. The paper recommended that entitlement should be based on residency and not on contributions.
Controversially, the Pension Commission report also proposed increasing the state pension age from 65 to 68 by 2050. It estimated that between nine and 12 million people in the UK are not saving enough for retirement.
Reform of the pensions system has been triggered by an ageing population and higher levels of life expectancy.
Publicity around the consultation will be handled in-house by the DWP press team. The campaign will be led by strategic comms
director Anton Teasdale.
