In the UK, increased use of non-structural responses (NSRs) in integrated urban flood risk management has been recommended since the flood of autumn 2000. Paralleling this change, the UK government are now strongly promoting a Whole Life Cycle Costing approach (WLCC) to flood risk management economic appraisals. However, due to a relative lack of economic knowledge in relation to NSR, costing non-structural responses is still in its infancy. Thus, the feasibility of the WLCC approach to costing non-structural strategies has been brought into question. This paper describes a qualitative method to assess the feasibility of WLCC approach, i.e. a method designed to assess if enough expert-based knowledge and/or economic data are available to support an effective, robust economic appraisal for a scheme that includes NSRs. This conceptual method allows flood risk managers to identify if, and when, further efforts are required in relation to obtaining better cost data to underpin a cost–benefit test. A user-friendly interface has been developed to support decision makers faced with these new challenges. A schematic project has been presented in the text to illustrate the potential application of the method.
