UK Electronic Travel Authorisation
Transforming the UK border through digital innovation
With a mandate to build a world-leading border that harnesses digital innovation to strengthen security, enable seamless travel, and leverage automation, the UK Home Office set out to deliver its ambitious Electronic Travel Authorisation (ETA) scheme.
This digital-by-default service is designed to pre-screen more than 30 million passengers every year before they travel to the UK by conducting identity and suitability checks, alongside enabling seamless entry for legitimate visitors. We supported the technical delivery of this multi-year programme, from strategic design through to scaled agile delivery and industry-wide change.
Strengthening borders through digital innovation
The UK is constantly having to adapt to ever-increasing passenger numbers, new threats, and operational challenges – and any change requires working across government departments, with carriers and ports, and a number of technology vendors.
ETAs were designed to strengthen border security by ensuring compliance and introducing upstream pre-travel checks for non-visa nationals – those not requiring a visa to travel to the UK. This proactive approach would enable the UK to identify potential risks earlier, prevent high-risk passengers travelling to the UK, and maintain robust border control.
To transform the vision into reality, the ETA scheme needed to create a comprehensive immigration journey for non-visa nationals. The goal was clear yet challenging: create a scalable digital service for millions of passengers that would meet policy and security requirements, without disrupting travel or adding friction for legitimate visitors.
We invested early in navigating external dependencies and demanding programme milestones, ensuring we were equipped to keep constant alignment between technical delivery and policy objectives throughout.”
Bringing ETA to life on strong foundations
To succeed, ETA would need more than expert digital delivery; it would require close policy collaboration, strong programme management, and preparation with the travel industry for this change.
We mobilised an experienced digital delivery team and began by clarifying priorities and constraints, running intensive workshops to surface trade-offs and aligning teams across digital, programme, policy, and operations behind a single ETA vision. This shared understanding enabled the programme to establish core requirements and shape a phased roll-out that built confidence across the delivery. Our experts fostered collaboration from the outset and led a digital team that utilised capability within the civil service and across several suppliers. From this foundation, we supported the design of a dual-channel service: a secure app using Near Field Communication passport scanning for identity verification, and a fully accessible web option to ensure a simple and inclusive application experience for the diverse user base.
The ETA service was developed on existing platforms and utilised established portfolio capabilities. PA coupled digital delivery excellence with deep domain knowledge and ensured that collaboration with Home Office teams and suppliers was front and centre.”
Building an automation-first solution
From there, we moved to build a minimum viable product (MVP). The service needed to capture biographic, biometric, and suitability data from each applicant and cross-reference it across systems to verify identities and run security and immigration checks.
Given the high volume and diversity of applicants, we aligned the system design with the principle of ‘automation by default’. With the ability to perform real-time threat assessments and minimise manual intervention, it ensured the ETA service would act as a central engine for both security and operational efficiency.
With policy, technical requirements and data models being shaped in parallel, delivery depended on agility: “our team focused on close collaboration, fast feedback loops, and continuous adaptation to keep the solution aligned as the programme evolved”, explained Calum MacAulay, PA Digital expert.
Readying the industry, passengers and operational teams for change
Following the successful MVP launch, we began scaling the service, with a key focus on supporting the programme to ensure the industry was prepared for the scale of change. The rollout took a phased approach over 16 months, starting with the Qatar public beta, before expanding across the Gulf, and later to Rest of World and European nationals.
A critical pillar of the launch was ensuring integration with carrier check-in systems and compliance with industry standards. We supported extensive carrier engagement workshops, providing hands-on support to cruise operators, airlines, and ground-handlers. At the same time, it prepared staff for a new, highly automated operational model.
Translating policy intent into structured technical deliveries, with a key focus on non-functional elements, was key to the success of ETA. We continually assured the system across hundreds of releases, ensuring its integrity and resilience before major public milestones.”
Redefining UK border security and efficiency
Two years post go-live, over 26 million ETAs have been issued, demonstrating the scale and reliability of the UK’s new and largest digital immigration product. The system has strengthened national security through proactive, pre-travel threat screening, while cutting average application decision times from seven hours to less than one minute.
ETA was a step-change for the Home Office in both the volume of applications and the critical reliance that passengers would have on the service. We needed a supplier that would do this with us, not for us, and PA gave us just that.”
