Flooding remains a significant concern for communities across the United Kingdom, with its impacts ranging from property damage to loss of life. As part of efforts to manage and mitigate flood risks, the Department for Environment, Food & Rural Affairs (DEFRA) has released updated guidance for Lead Local Flood Authorities (LLFAs) regarding their responsibilities to investigate flood events under Section 19 of the Flood and Water Management Act 2010.
This updated guidance aims to streamline flood investigation processes, improve consistency across LLFAs, and ensure that lessons from past events are integrated into future flood management strategies.
The role of LLFAs and Section 19 of the Flood and Water Management Act 2010
Section 19 of the Flood and Water Management Act 2010 places a duty on LLFAs to investigate flooding incidents in their areas, specifically when two or more properties are affected. These investigations help to identify the causes of flooding, the parties responsible, and recommend actions to prevent future occurrences. The updated guidance, which was issued by DEFRA, provides clarity on how LLFAs should approach flood investigations and highlights the importance of timely and thorough assessments.
Under the previous guidance, there was some ambiguity regarding the scope of investigations and the resources required to complete them. The new guidelines seek to address these challenges by offering clearer procedures, enhanced collaboration with stakeholders, and a more structured framework for reporting findings.
Key updates in DEFRA’s guidance
- Clarification of roles and responsibilities
One of the most significant updates in the revised guidance is the clearer delineation of roles between LLFAs, other relevant authorities, and flood risk management partners. The guidance underscores the importance of collaboration, emphasising that LLFAs should work closely with the Environment Agency (EA), water companies, local authorities, and other relevant organisations to gather data and analyse flood events effectively.
It is explicitly stated that LLFAs should not work in isolation when investigating flooding events but should instead seek the necessary expertise from those who may have a role in flood risk management, such as drainage authorities, internal drainage boards (IDBs), and landowners.
- Consistent reporting and documentation
The updated guidance also introduces standardised reporting procedures for flood investigations. This includes recommended templates for documenting flood events, detailing the investigation process, and providing a consistent approach to presenting findings. The aim is to ensure that all relevant parties are able to access and understand the information related to specific flood events.
LLFAs are now encouraged to keep comprehensive records of their investigations, including the methodology used, data sources, and any limitations encountered during the process. This documentation will serve as a valuable resource for future flood risk management, policy decisions, and improvements in flood resilience.

Timeliness of investigations
In previous years, delays in flood investigations have been a recurring issue, sometimes hindering the effectiveness of subsequent flood risk management efforts. The new guidance outlines more specific timelines for completing investigations and submitting reports. It stresses that flood investigations should be prioritised and completed as quickly as possible following a flood event, typically within three months, unless exceptional circumstances arise.
This improvement ensures that local communities are provided with critical information regarding the causes of flooding in a timely manner, which is vital for long-term planning and prevention.
Risk-based approach to investigations
The updated guidance encourages LLFAs to take a risk-based approach to flood investigations. Instead of investigating every minor flood event, LLFAs are advised to focus their efforts on those incidents that pose the greatest risk to people, property, and infrastructure. This prioritisation ensures that resources are used effectively and that investigations are conducted where they will have the most significant impact on reducing flood risks in the future.
LLFAs should also assess the potential for cumulative or compounded flood risks, such as those arising from climate change, urban development, and changes in land use. Understanding how multiple factors interact to increase flood risk will enable more comprehensive flood management strategies.
Public engagement and communication
Another crucial update is the emphasis on better communication with the public. The updated guidance highlights the need for LLFAs to ensure that communities affected by flooding are informed about the investigation process and its outcomes. This transparency builds trust with local residents and ensures that the results of investigations are accessible and understandable.
LLFAs are encouraged to engage with local communities throughout the investigation process and to share findings through clear and concise reporting. This open dialogue ensures that residents are better informed and can actively participate in flood risk management and mitigation measures.
Conclusion
The updated guidance from DEFRA represents a significant step forward in improving the efficiency, consistency, and transparency of flood investigations carried out by Lead Local Flood Authorities. By clarifying roles, setting clearer expectations for timelines, and encouraging collaboration, the guidance aims to enhance the effectiveness of flood risk management across the UK.
As the impacts of climate change continue to exacerbate flood risks, the need for comprehensive, well-documented investigations has never been more critical. The updated Section 19 guidance provides LLFAs with the tools and resources to better understand flood events, improve resilience, and ultimately protect communities from the devastating effects of flooding.
For local authorities, flood risk management professionals, and residents alike, this updated framework is a positive development that strengthens the UK’s collective ability to manage flood risks and safeguard vulnerable communities.
