Conclusion
When we asked the Agency how it assesses overall national flood risk for non- residential buildings, agricultural land and infrastructure it said that it does not measure this unless it is part of a particular flood scheme. So, for example for agricultural land, the Agency does not know what has happened to the overall level of flood risk over the current investment period 2015–6 to 2020–21.23

5.1 The government agrees with the Committee’s recommendation. Target implementation date: Spring 2022 5.2 The department and the Agency are developing a framework for understanding overall flood risk. This framework uses an improved method for calculating the risk reduction achieved by the capital investment programme alongside changes in risk due to other factors such as housing development, climate change and the condition of flood defence assets. Flood risk will be measured using expected annual damages (EAD) and changes to numbers of properties at different flood likelihood. During 2021, further work will be done to improve these measures, more accurately identifying the contribution of different factors, including the capital investment programme, to changes in overall risk. The Agency will also consider what changes could be made to the current National Flood Risk Assessment (NaFRA) to improve the interim position before a new NaFRA becomes available in 2024. 5.3 This work on understanding overall flood risk includes the development of a set of KPIs that will better track progress of the 2021-2027 capital programme specifically. By Spring 2022, the department will have in place the full suite of metrics (KPIs), agreed with the Agency, and a new oversight process that will aid in monitoring flood risk. Methods of data collection, validations and reporting will be subject to ongoing refinement once the metrics are in place. 5.4 In addition, the department has committed to develop an overall national set of indicators by Spring 2022 to monitor trends over time in tackling flood and coastal erosion in England. These will enable a better understanding of the impacts of government’s policies and will inform future action. The department will set out further details in due course.
