Recommendation 13
13
Not Addressed
Initiate consultation on statutory requirements for assessing cumulative impacts of development on flood risk.
Recommendation
We reiterate that the Government should ensure that flood and climate resilience are embedded into the core tools of planning, regulation, and investment appraisal. The NPPF should be strengthened to prioritise flooding avoidance and climate adaptation, mandating sustainable drainage systems and consider the need for property flood resilience measures in all new developments through building regulations. As stated in our recent report on flood resilience, the Government should initiate a consultation on statutory requirements for assessing the cumulative impact of development on flood risk within local and regional plans by the end of
Government response summary AI-generated
The government's response refers to monitoring and implementation of the Nature Restoration Fund (NRF), which does not address the recommendation to embed flood and climate resilience in planning tools, strengthen the NPPF, mandate sustainable drainage systems, or consult on cumulative flood risk impact.

23. The NPPF already makes clear that local planning authorities should take a sequential and risk-based approach to flood risk. In doing so, development should be directed away from areas at highest risk, and should be made safe for its lifetime without increasing flood risk elsewhere. It also requires developments of all sizes which could have drainage impacts to incorporate sustainable drainage systems. 24. On 16 December 2025 Government published a consultation on a new NPPF which included updated policies on climate change adaptation and mitigation, flood risk and sustainable drainage systems. Our proposed plan- making policies are clear that development plans should be informed by an up-to-date Strategic Flood Risk Assessment (SFRA) which considers current and future flood risk from all sources, including cumulative impacts in, or affecting, areas susceptible to flooding. 25. We also proposed a new requirement for sustainable drainage systems to be designed in accordance with new national standards that were published in 2025. These national standards make clear that schemes should be designed to cope with changing climatic conditions. 26. Statutory guidance accompanying the Building Regulations already promotes flood resilient building work in flood-prone areas, through Approved Document C. This may include adequate sub-soil drainage; use of non-return valves and anti-flooding devices on sewers and drains; water resistant construction; and provision for inspection and clearance of sub- floor voids.
