The UK Home Office built Atlas for eight years. It went live after a handover from the legacy Casework Information Database (CID) in 2025. But a new report from the Independent Chief Inspector of Borders and Immigration says Atlas still does not enable the department to provide data or feedback on the outcomes of asylum appeals to decision-makers, undermining the whole point of switching systems.

The stakes are not academic. The inspector reports that asylum-status appeal counts jumped from 8,000 in 2022-23 to well over 29,000 in 2023-24, and the system that should help the Home Office learn from those outcomes has left “local workarounds” in place instead. The report covers the period from June to December 2025 and concludes that the Atlas shortcoming “hindered the ability to identify and monitor trends and to learn effectively from appeals.” In other words: the appeals machine is producing more data, but the organization running it lacked a reliable way to turn those outcomes into learning.

To understand why this matters for executives and boards, you have to look at how regulatory and oversight ecosystems work in high-stakes public services. Asylum appeals are politically sensitive, decisions are challenged, and every cycle of litigation becomes both a legal risk and an operational feedback loop. When the feedback loop breaks, the organization often compensates with manual work. The Home Office is described as having implemented “local workarounds” because the promised data and feedback functionality was not available during and after the CID-to-Atlas transition.

The inspector’s report also spells out what the Home Office would have to do to fix it. It says the Home Office’s work “to resolve this was ongoing but required a full rebuild of other platforms.” That detail is a red flag for anyone who has ever tried to bolt missing features onto a live enterprise system. It implies Atlas was deployed into an environment where downstream systems, integrations, or supporting data structures were not ready to carry the specific information needed by decision-makers. If the solution truly requires a rebuild of other platforms, the fix is not a quick patch. It is a program inside a program.

The timeline gets even more uncomfortable. The Register reports that Atlas development was described by the Home Office as an eight-year journey, shaped by major global events including Brexit, Covid, the Afghan Citizens Resettlement Scheme, and the Ukraine Citizens Schemes. Atlas was built by suppliers including Accenture, Mastek, and PA Consulting. Contracts with work starting from 2020 were valued at around £79.7 million. As of 2019, it was projected to be fully implemented in 2021, but the department missed that deadline.

Then the calendar kept slipping. In 2023, The Register revealed the Home Office missed a second deadline for the full handover and decommissioning of CID. At the time, the department told the spending watchdog, the National Audit Office, it would stop using CID by September 2023, but it missed that deadline too. As of December 2025, there was still evidence that Home Office staff were using the legacy system for some information. This matters because dual-running systems is expensive, error-prone, and operationally distracting, even before you factor in what happens when the newer system cannot provide the feedback loop the appeals process generates.

Fast forward to 2025 and 2026, and you get the most telling twist: the system transition looks “done,” but the learning gap is still the issue. The Register has asked the Home Office whether it completed the remediation work. In 2025, the Home Office said Atlas completed its replacement of CID. But as of June 2026, a report from the Public Accounts Committee, Parliament’s spending watchdog, confirmed the department no longer used the legacy system. Even then, the committee found staff did need to maintain their own spreadsheets alongside the official system. That detail is a classic second-order effect: the organization may have removed the old system, but it did not remove the need to do manual data work when official tooling cannot reliably deliver decision-grade feedback.

For peers in technology leadership, operations, or board oversight, the pattern is hard to miss. A large modernization program can hit formal milestones while still failing the functional requirement that actually drives performance: turning case outcomes into insights. In the Home Office’s case, Atlas launched without the functionality caseworkers needed “to provide data or feedback on the outcome of asylum appeals to [decision-makers].” Meanwhile, appeal volumes rose sharply, from 8,000 in 2022-23 to well over 29,000 in 2023-24. That combination raises the risk that the organization accumulates more outcomes it cannot learn from, just as oversight scrutiny increases.
