Festival planning permission: reducing the risk of legal challenges from local residents

Nichola Evans, Partner

Festival organisers using public parks are facing increasing scrutiny over planning permission, permitted development rights and resident objections. Recent High Court challenges involving Brockwell Live show how quickly community opposition can become a legal, financial and operational risk.

Under permitted development rules, planning consent is not required where the temporary change of use of land lasts for no more than 28 days in a calendar year. In 2025, Protect Brockwell Park (PBP), a local residents’ group, brought legal action against Lambeth Council, arguing that the festival build period and the events themselves meant the park would be unavailable for 37 days. The High Court accepted PBP’s interpretation of the 28-day rule. Although PBP urged the Council to cancel events including Wide Awake, Field Day, City Splash, Cross the Tracks, Mighty Hoopla, Lambeth Country Show and Brockwell Bounce, the organiser applied for amended permission limited to 24 days, allowing the festivals to proceed.

In 2026, PBP brought a further High Court challenge, this time alleging that Lambeth Council’s decision-making involved “flawed reasoning, missing evidence, and vague environmental promises”. Announcing the action, PBP said it considered that “a large, commercial, ticketed festival is being treated as if it were an ordinary use of a protected public park”. Its argument focused on whether an open-air music festival fell within the meaning of “recreation” under paragraph 154(b) of the National Planning Policy Framework.

The High Court rejected that argument and held that music festivals could fall within the definition of “recreation”. The Court also noted that 74% of the park would remain open to residents while the festivals were taking place.

Key takeaways

PBP funded its challenges through crowdfunding, and the claims involved not only the Council but also the events company as an interested party. For organisers, the practical risk is clear: even where the underlying event planning is well advanced, judicial review proceedings can require significant management time, legal cost, and evidential preparation at short notice.

Practical checklist for festival organisers

To reduce the risk of planning objections, judicial review or last-minute disruption, festival organisers should consider the following steps at an early stage:

• Check whether the event can lawfully rely on permitted development rights, including the total number of days the land will be unavailable for build, event operation and de-rig.
• Keep clear evidence of decision-making, including how planning, environmental, noise, traffic, safety and public access issues have been assessed.
• Engage with local residents and community groups early, particularly where an event takes place in a public park or other sensitive community space.
• Document any environmental commitments carefully and ensure they are specific, realistic and capable of being evidenced if challenged.
• Consider how much of the site will remain accessible to the public during the event period and whether this can be clearly explained.
• Review all licence, planning and contractual documents to ensure deadlines, permissions and responsibilities are aligned.
• Prepare for the possibility of urgent legal action by keeping key documents organised and seeking advice promptly if objections escalate.
