UK ditches Palantir Foundry for in-house refugee matching system, saves millions

The UK’s Ministry of Housing, Communities and Local Government has replaced the Palantir Foundry-based system that powered the Homes for Ukraine refugee resettlement scheme with an in-house build, claiming millions in annual savings and tighter control over data and code. Palantir originally stood up the platform for free in nine days back in March 2022, then converted that foothold into 12-month contracts worth £4.5m and £5.5m — a pattern the government’s chief commercial officer warned ran counter to open-procurement principles. The replacement went live in September 2025.

Project lead Coco Chan framed the migration as a precedent for moving complex live systems off commercial platforms, and critics of Palantir’s expanding UK footprint — across the NHS, MoD, FCA and 11 police forces — are treating it as a proof point for ‘sovereign technology’ and reduced dependence on large US vendors. Palantir countered that the swap actually demonstrates customers aren’t locked in, and pointed to its broader Ukraine-related work including military support and war-crimes investigations.

Industry voices were more measured: BCS and Public Digital noted that in-house builds work when government invests in genuine engineering capability, but external suppliers still matter for urgent programmes needing large teams fast. The episode sharpens an ongoing UK debate over procurement practices that let zero-cost pilots convert into multi-million-pound sole-source contracts.
