A spending review published on 31 August 2026 examines the organisation of Belgium’s closed centres and their role in the return chain. It finds that the centres operate relatively efficiently within current constraints, while identifying structural challenges affecting the use of available capacity. As of 20 May 2026, 541 of the 689 theoretical places were effectively usable, with 148 unavailable due to infrastructure problems or staff shortages. The review puts forward 74 recommendations and more than 170 concrete actions across nine areas.
