The large-scale simulation, known as Exercise Firebird, brought together Counter Terrorism Policing London, the Metropolitan Police, London Fire Brigade, London Ambulance Service, private security teams and Canary Wharf Group security to test coordinated response to a simulated marauding terrorist attack.

A section of the Canary Wharf estate was temporarily closed to the public while the scenario unfolded, involving multiple staged casualties, specialist response teams and supporting role players to replicate a major incident environment.

According to Counter Terrorism Policing London, the exercise was not linked to any specific threat or intelligence, but formed part of ongoing preparedness planning designed to test response capability in high-density urban environments.

A key focus of the exercise was interoperability between emergency services and private sector security teams operating within the estate. Canary Wharf security personnel worked alongside police and emergency responders, reflecting the increasingly integrated role of private security in first-response environments such as major business districts and transport hubs.

Counter Terrorism Policing London said the exercise also incorporated lessons from previous real-world incidents, including coordination challenges identified in past UK terror attacks, and tested the use of technologies such as drones to support situational awareness during complex incidents.

The UK’s national terrorism threat level remains “substantial”, meaning an attack is considered likely, underscoring the continued emphasis on preparedness and multi-agency coordination. While exercises of this scale are rare in central London, authorities say they are critical in ensuring response plans remain effective as urban environments, infrastructure and threat profiles continue to evolve.

For the security industry, the exercise highlights the growing importance of collaboration between public emergency services and private security operators in managing large-scale incidents in complex, high-footfall environments. As security operations become increasingly integrated across public and private stakeholders, exercises such as Firebird are being viewed not only as training events, but as essential stress tests of modern urban resilience.
