Project overview
Designing a digital identity service to government standards.
GOV.UK Verify was designed to give UK citizens a secure way to prove their identity and access government glossaryServiceA service is a component or function that performs a specific task within a system.Open glossary term online.
Rather than a single provider, the glossaryModelA model is a system or representation used to process data and generate outputs, often trained to perform specific tasks.Open glossary term allowed multiple organisations to compete as identity providers. Experian was one of them.
I was brought in to glossaryLeadA lead is a potential customer who has shown interest in a product or service, typically by providing contact information or engaging with content.Open glossary term UX design for Experian’s solution, working within the GOV.UK ecosystem and its strict standards.

The challenge was clear. Make identity verification simple for users, while meeting one of the most rigorous digital standards in the UK.
What was happening
Security was high. Completion rates weren’t.

Users were required to provide personal information, verify documents and complete multiple steps to prove who they were.
Security and fraud prevention were critical, but they introduced glossaryFrictionFriction refers to anything that slows users down or makes it harder for them to complete a task.

Approach
Design to GDS standards. Validate everything.
The approach was grounded in GDS principles from the start.
Every glossaryInteractionInteraction refers to any action a user takes within a product and how the system responds. It includes clicks, taps, gestures, and inputs that drive the user experience.Open glossary term was designed using GOV.UK glossaryPatternA reusable solution to a common design problem.Open glossary term, ensuring glossaryConsistencyConsistency is the use of uniform patterns, behaviours, and visual elements across a product to create familiarity and predictability. It helps users learn once and apply that knowledge throughout the experience.Open glossary term with the wider ecosystem and reducing cognitive load for users already familiar with government services.

Key decisions
Simplify without weakening security.
A key decision was to focus on glossaryClarityClarity is how easily users can understand what is happening and what they need to do.Open glossary term rather than reducing security.
The glossaryProcessA process is a defined sequence of steps used to achieve a specific outcome.Open glossary term couldn’t be removed, but it could be made easier to understand.
Instructions were simplified, steps were refined, and users were guided more clearly through what was required and why.
Another critical decision was to treat GDS standards as a foundation, not a constraint.
Rather than working around them, the design leaned into them. Using familiar glossaryPatternA reusable solution to a common design problem.Open glossary term and language to reduce glossaryFrictionFriction refers to anything that slows users down or makes it harder for them to complete a task.

This ensured the glossaryServiceA service is a component or function that performs a specific task within a system.Open glossary term felt consistent with GOV.UK, while still meeting the specific needs of identity verification.
Solution
A secure, accessible and compliant identity journey.
The result was an identity verification experience that balanced glossaryUsabilityUsability is how easy and efficient it is for users to complete tasks within a product.

Reflection
Standards don’t limit design. They sharpen it.
