• Contract modified due to additional needs.

Legal Justification

The modification is made in accordance with Regulation 72(1)(b) of the Public Contracts Regulations 2015. Additional services by the original contractor have become necessary following withdrawal of the Home Office's 2025 Atlas re-procurement process. The withdrawal of that procurement has resulted in a requirement to maintain continuity of critical immigration case working services until a replacement procurement can be completed. Market engagement for the new procurement commenced in June and is being progressed on an urgent basis. A change of contractor cannot be accomplished at this stage because it would cause significant inconvenience and substantial duplication of costs. The Atlas platform is complex, highly integrated and relies on specialist knowledge held by the incumbent supplier. Transitioning the service to a different provider within the available timeframe would require extensive procurement, mobilisation, onboarding and knowledge-transfer activity. Such an approach would introduce material operational risk and would not provide sufficient assurance that critical services could continue without disruption. The modification is therefore necessary and proportionate to ensure uninterrupted service delivery while the Home Office completes its replacement procurement and transition activities. The increase in value remains below the threshold permitted under Regulation 72(1)(b).
