TL;DR
The UK Department of Housing replaced Palantir’s tech in the Homes for Ukraine scheme with an in-house system, saving millions annually. This move aims to increase control and reduce reliance on external suppliers.
The UK government has replaced the Palantir-based IT system used in the Homes for Ukraine refugee scheme with a new in-house platform, saving millions of pounds annually. This shift aims to improve system flexibility, security, and control, marking a move toward greater technological sovereignty.
The Homes for Ukraine scheme, which matched Ukrainian refugees with hosts offering free accommodation, initially relied on Palantir’s Foundry platform. The system was supported by Palantir at no cost for the first six months, but costs grew to millions as the scheme expanded. In 2023, the UK Ministry of Housing, Communities and Local Government (MHCLG) announced it had replaced the Palantir system with a new, internally developed platform. Senior digital leader Coco Chan stated that the new system was already saving the department millions of pounds per year in operational costs.
The transition was driven by a desire to reduce reliance on external vendors and to develop a more flexible, secure, and controllable system. The new platform was operational by September 2025, fulfilling a long-term goal of creating ‘sovereign technology.’ The move has been seen as a precedent for other government departments considering similar in-house solutions.
Why It Matters
This development is significant because it demonstrates the UK government’s shift toward building more autonomous digital infrastructure, reducing dependence on large US tech firms like Palantir. It also highlights the potential for cost savings and increased control over sensitive data. Critics of reliance on external vendors, especially large private tech firms, see this as a positive step toward technological sovereignty and improved public sector resilience.

Background
The UK government initially engaged Palantir to develop a system to manage the complex task of coordinating refugee accommodations during the Ukraine conflict. Palantir’s support was provided at no initial cost, but the scheme’s expansion led to rising costs. The government has expressed concerns about vendor lock-in and the desire for more control over critical systems, prompting the development of an in-house solution. This move is part of broader discussions about reducing dependence on foreign technology providers in public services.
“Longer term, we wanted to replace the platform with a more flexible technology solution, enabling [MHCLG] to save significant support costs, control the system data and code.”
— Coco Chan, senior digital leader of Homes for Ukraine
“Our support for the Homes for Ukraine scheme included deploying our software to help Ukraine in various ways, including military support and investigation of war crimes.”

“When given suitable resources, the Civil Service can often outperform private companies like Palantir. The development of an in-house alternative is an important step towards more ‘sovereign technology.'”
