The August 2026 NPPF changes how flood risk is assessed at planning stage. This technical guide explains the revised FRA triggers, surface water Sequential Test rules, SuDS requirements and design implications for new development.
Technical lessons from the 2026 Yatton and Faversham judgments on flood risk, NPPF paragraph 11, mitigation and planning evidence.
The Environment Agency updated the Flood Map for Planning on 28 May 2026. New surface water climate change extents and banded depth information are now live. Here is what architects, planners and developers need to know.
The December 2025 draft NPPF proposes the most significant shift in flood risk planning policy in over a decade. For developers and architects, the direction is clear: drainage moves to the front of the design process, viability assessments get harder to flex, and national flood mapping is already catching sites off guard. Here is what the proposals mean in practice and three things worth doing before the final policy lands in Summer 2026.
