In October 2021, the government asked the Commission to conduct an assessment of how responsible bodies in England can better manage and mitigate surface water flooding.
The final report – Reducing the risk of surface water flooding – was published on 29 November 2022.
The work of the study included:
- analysis of the current risks of surface water flooding (including sewage overflows) and the opportunities that exist to address these in the short and long term
- recommendations concerning improvements needed to England’s drainage systems to manage and prevent surface water flooding in both urban and rural economies, including through nature-based solutions alongside hard engineering
- consideration of the optimum cost-benefit analysis of infrastructure options and how these can be combined to provide greater resilience and value for money.
This now-completed study covered England only, as flooding and water management is a devolved function.
The Commission liaised with flood risk management authorities to carry out the study, and consulted infrastructure providers, engineering sector and environmental NGOs to maximise the breadth of understanding and opportunities.
The Call for Evidence to support the scoping and research phase of the project closed on 20 December 2021.

Commission welcomes move to more sustainable drainage for new developments
The government has today (10 January 2023) announced its intention to implement Schedule 3 of the Flood and Water Management Act in England (subject to consultation). This shift in policy will make sustainable drainage solutions the default for almost all new developments in England, and make the right to connect surface water runoff to public...
600,000 properties face future flooding without action to reduce urban runoff and improve drainage systems
Stricter controls on new property developments alongside up to £12bn of investment in drainage infrastructure over the next thirty years will be necessary to stop thousands more homes and businesses from flooding due to inadequate drainage, according to a new report by the National Infrastructure Commission. Localised floods across England last month alongside a series...
