Our annual Planning Conference offers a full day of in-depth, practical learning on the latest developments in planning law, delivered by leading planning experts. This year’s programme will explore the latest legislative and policy changes and case law developments, with a specific focus on areas of particular relevance to local authority planning lawyers and officers.

The day will begin with a welcome from Rachel McKoy, LLG National Lead for Planning, Highways and Environment, followed by a session on the National Planning Policy Framework (NPPF), delivered by an expert in the field (speaker details to be confirmed). This will be followed by a presentation on the Environment Act 2021’s Environmental Principles and Local Government Decision Making, delivered by Toby Fisher, Barrister at Matrix Chambers.

Later in the programme, Tim Straker KC and Vivienne Sedgley, Barristers at 4-5 Grey’s Inn Chambers, will present on the new devolution agenda, focusing on practical implications for planning. This session will explore the English Devolution and Community Empowerment Bill, including the creation of new Strategic Authorities, a Devolution Framework, Local Transport Plans, Local Transport Authorities, and proposed changes for the Greater London Authority.

Delegates will also benefit from a Case Law Update, presented by a barrister from Landmark Chambers (speaker details to be confirmed), followed by a session on Infrastructure Bill Changes led by Stuart Evans, Partner and Head of Planning at Anthony Collins, and Max Howarth, also from Anthony Collins.

One further session will be included, with the topic and speaker to be confirmed. The day will conclude with closing remarks from LLG's National Lead for Planning, Highways and Environment.

Each session will provide attendees with the opportunity to ask questions and share their thoughts and experiences. While the event will be held across one day, all sessions will be recorded and made available to download, allowing participants to engage fully on the day or attend selected sessions and catch up at their convenience.

Further details on the remaining topics and speakers will be made available in due course. The conference offers an ideal opportunity for planning lawyers, officers, and anyone working in a local authority planning team to stay up to date with the most important recent developments in planning law.
