Question to the Department for Environment, Food and Rural Affairs:

To ask the Secretary of State for Environment, Food and Rural Affairs, with reference to his Department's case study entitled Mental health costs of flooding, published on 4 April 2025, whether the prices used are for 2025.

The Mental health costs of flooding and erosion case study found the mental health losses per adult per flood event to be £1,878 per adult per flood for shallow floods (less than 30cm of water in a home). This increases to £4,136 per adult per flood for deeper, more severe floods (when water is over 1 metre deep).

These values are the same as those available in the supplementary guidance Mental health costs of flooding and erosion.

The mental health cost values in the case study are at 2018 prices, the same as the underlying guidance.
