Carnival security reached a new scale at Notting Hill’s 60th anniversary event this August, and the numbers tell their own story. Around 3,500 stewards were deployed across the two-day carnival, roughly double the 1,750 typically used in previous years, backed by an extra £4.6 million grant from City Hall, around 90 temporary CCTV cameras, 40 large public-message signs and a bigger control room. For any organiser running a large public event in the UK, the 2026 operation is now the reference point for what proportionate carnival security looks like at genuine scale.
The results were mixed in the way large, high-attendance events usually are. Police recorded 560 arrests over the weekend and 62 weapons seizures, including a handgun recovered on the Monday, alongside two knife-related assaults, one stabbing and one slashing, neither life-threatening. An investigation continues into the death of a man who entered a canal while being pursued by police near the parade route. None of that is a verdict on whether the extra stewarding worked; it reflects the reality that an event drawing roughly two million people across two days will surface serious incidents regardless of preparation. What the figures do show clearly is that heavier investment in visible stewarding and technology changed what organisers were able to see and respond to in real time.
Facial recognition made its carnival debut
The most significant operational change was the first-ever use of live facial recognition at the carnival. The Metropolitan Police said the technology led to 48 arrests on the Monday and helped officers identify 43 registered sex offenders in attendance, several of whom were in breach of notification or exclusion conditions. Facial recognition at an event of this scale raises the same proportionality questions it has raised at retail sites and football grounds: whether a watchlist is tightly scoped, how long footage is retained, and whether the deployment is clearly signposted to the public. Organisers considering similar technology for their own events should treat those questions as part of the planning process, not an afterthought once cameras are already up.
What smaller events can actually take from a £4.6m operation
Few organisers have anything close to a City Hall grant or 3,500 stewards to call on, but the underlying principle scales down. Carnival security at Notting Hill worked on a ratio of stewarding to expected footfall, a control room able to see and act on incidents across the whole footprint rather than in isolated pockets, and clear public messaging to help crowds self-manage around known pinch points. A community festival or a mid-sized outdoor event can apply the same logic proportionately: enough visible, briefed stewards for the specific crowd size expected, a single point of command rather than fragmented radio channels, and signage that tells attendees what to do if something goes wrong. Martyn’s Law will require exactly this kind of structured planning from a growing number of UK venues and events as it moves toward full commencement.
Coverage from the Greater London Authority and the Metropolitan Police’s own post-event statements are worth reading directly by anyone benchmarking their own event security budget against carnival scale.
Our event security team plans stewarding ratios, control-room structure and crowd management for events from community festivals to citywide carnivals, scaled to the specific footprint and expected attendance.

Whatever budget an event has, the lesson from this year’s carnival security operation is the same: visible, well-coordinated stewarding backed by a real control room changes what organisers can see and do, long before anything goes wrong.
