title: Corrigendum.
abstract: The authors of the November 'In Practice' article published in Perspectives in Public Health 2015; 135(6) would like to make clear that:The project took place in South East London rather than East London.Thamesmead is an area which straddles the boroughs of Greenwich and Bexley, not a borough itself.The Thamesmead Health Champions emerged from Royal Greenwich Public Health supported by local churches. Trust Thamesmead joined after the programme was established - their continuing support is fantastic.The authors apologise for these minor errors.
