The Government Digital Service (GDS) has awarded business consultancy Deloitte a contract to support the development of the One Login service.
The deal, set to run for two years and valued at up to £9 million, is the second for the company to work with GDS on its digital identities for government services programme, following the award in February of a £4.8 million contract to develop a mobile app for digital identity checks.
According to the contract notice for the new deal, Deloitte will take on the role of professional services delivery partner in the programme and provide multi-disciplinary teams to deliver outcomes based statements of work.
It marks the latest step in the programme to replace the ill fated GOV.UK Verify service, which is currently being run down after limited take-up in central government.
The development of One Login is already well advanced with a plan for the Disclosure and Barring Service to be the first to use it from this month.
Last September, GDS chief executive officer Tom Read outlined the development plans for One Login, saying it will need different methods of identification for different groups of people.
