DCMS launched the Culture and Heritage Capital (CHC) Programme in 2021 with our arms length bodies (ALBs). The aim is to ensure the economic, social and cultural value is included in appraisals and evaluation, following best practice guidance set out by HM Treasury’s Green Book. Without an agreed method for valuing the flow of services that CHC assets provide, the impact of proposals on specific groups, households, communities and businesses is underestimated, particularly during social cost benefit analysis (SCBA).
