Atlas & Immigration Caseworking is the Home Office’s business-critical system used by caseworkers to manage the processing of visa and asylum applications. It also provides operational functionality for Border Force and Immigration Enforcement. The system has a requirement to 24 hours a day, 7 days a week availability, with updates and enhancements continually delivered to enhance functionality and capabilities. It underpins a range of critical national priorities and a significant amount of continuous improvement work driving strategic outcome delivery from the Caseworking Capability.
The objective is a re-procurement to replace the following two incumbent contracts:
This new procurement is intended to replace the withdrawn procurement for Atlas Caseworking (Asylum & Non-Asylum) whose market engagement was conducted in March 2025 as itt_81818 under the GCA Technology Services 3 framework.
Both those contracted services cover and provide Development and Level 3 Support to the Atlas Caseworking platform, a containerised Open-source Java microservice application deployed into AWS, which orchestrates workflow following Business Process Management processes, triggered by events, using agile release trains which group microservices for release.
This procurement is expected to be conducted through a GCA framework.
In addition to re-procuring these services, the objective of Atlas & Immigration Caseworking is to evolve and enhance the overall immigration caseworking operating model, with a greater emphasis on supplier accountability, collaboration, and strategic partnership.
The Home Office will be going to market for supplier(s) who can provide the following services:
| Lot | Title | Value |
|---|---|---|
| 1 | Lot 1 | — |
Suppliers are requested to continue monitoring the original PMEN for any updates or further clarifications relevant to the current procurement.
