Description:
The Department for Science, Innovation and Technology (DSIT), through the Government Digital Service (GDS), is undertaking preliminary market engagement in relation to a potential future procurement for Digital Delivery Partners to support GOV.UK One Login.
GOV.UK One Login is being developed as the single sign-on and identity verification front door for accessing government services. This will replace up to 300 individual accounts, accessed via 44 different sign-in methods; and will provide a significantly improved user experience. Our aim is to make it as simple, inclusive, and secure as possible for individuals to prove their identity and access connected services, while protecting them and the government from the risks of fraud.
GOV.UK One Login enables users to create a secure account quickly and easily so they can use it each time they need to access a government service. For those services that require enhanced assurance, users can then prove (and reuse) their identity through either a web-based journey, smartphone app or in-person route.
GOV.UK One Login is continuing to scale, with 245 services already onboarded, for example apply for a Disclosure and Barring Service (DBS) check and Sign your mortgage deed. Over time, all central government services will be accessible through GOV.UK One Login.
Over 15 million people have proven who they are through One Login, and its identity verification app - which has a rating of 4.7* on Android and iOS stores - has been downloaded more than 20 million times.
The programme currently leverages multiple arrangements to provide technical resource capacity and capability in digital product development and delivery. The Authority is considering procuring the next generation of Digital Delivery Partners through Crown Commercial Service Digital Outcomes and Specialists 7 (DOS7), Lot 2 – Digital Capability and Delivery Partners, using a multi-stage competition. The new arrangements are targeted to be fully operational by Spring/Summer 2027.
Note: this notice is issued for preliminary market engagement purposes only. It is not a call for competition and does not commit the Authority to launch any procurement or award any contract.
Scope:
The Authority is currently considering a delivery model under which five delivery partners would be appointed through a single, lotted procurement. Each partner would provide a common core set of agile delivery capabilities together with deeper expertise in one specialist area. The specialist areas currently under consideration are:
| Lot | Title | Value |
|---|---|---|
| 1 | Lot 1 | — |
The Authority is also considering including additional headroom for cross-programme use within GDS.
Estimated value:
Estimated total value: £120,000,000 - £280,000,000
Estimated annual value: £40,000,000 - £95,000,000
Estimated total value per contract:
These figures are based on current planning assumptions and are subject to approvals, final scope and procurement design. Note: that contracts are likely to be zero committed spend.
Additional information:
GOV.UK One Login is intended to replace multiple legacy sign-in and identity systems across government, improving user experience, reducing duplication, strengthening counter-fraud protections and realising financial benefits. The programme currently operates with a core team of approximately 600–650 FTE and utilises external suppliers to supplement internal civil service capability at the scale required.
GDS has an ambitious roadmap to further enhance GOV.UK One Login and introduce significant new capabilities. The new arrangements are expected to support broader delivery across the GOV.UK portfolio principally Wallet and verifiable credentials, including Digital ID.
The Authority reserves the right to amend, suspend or discontinue this preliminary market engagement at any time. Nothing in this notice shall be taken as implying that the Authority will proceed with any procurement or enter into any contractual arrangements. A UK2 notice supports transparency and market awareness but does not itself commence a competitive procurement.
