Welsh Government issues revised TAN 15
The Welsh government has published new planning guidance titled ‘Guidance on The Town and Country Planning (Flood Risk Area Development) (Notification) (Wales) Direction 2025 (WGC 002/2025)’ to better protect communities from flooding. The guidance helps planners assess flood risks from various sources and provides advice on adapting to and living with flood risk. It emphasises the increasing frequency and severity of flooding due to climate change and introduces a risk-based approach using the Flood Map for Planning. Additionally, the revised Technical Advice Note 15 (TAN 15) supplements policies in Planning Policy Wales and Future Wales, focusing on reducing flood risk and developing away from high-risk areas. The new guidance is effective on 1 Aril 2025, with a transitional period for ongoing applications.
