<jats:title>English</jats:title> <jats:p>How does regeneration affect health and how have successive urban policy evaluations sought to measure such impacts? This article draws on a systematic review of nationallevel evaluation documentation relating to government-funded, area-based regeneration initiatives in the UK since 1980. The review examined whether health impacts had been intended and, if so, how they had been measured. The process and difficulties of conducting the review raise significant questions about policy formulation and evaluation. Is evidence-based policy possible where evaluations are not stored centrally? In short, a model policy development as ‘enlightened’ or incremental is hard to sustain where a lack of systematic storage of data means that researchers, policy makers and practitioners may struggle to produce clear answers to important policy questions.</jats:p>
