Planning a high-profile event or product launch in London?
London is one of the world’s leading corporate event cities: home to a professional-grade events infrastructure, an established private security industry, and a regulatory framework that is among the most developed globally.
The security environment
The UK terrorism threat level is SEVERE, meaning an attack is judged highly likely. London has experienced multiple significant attacks: Westminster Bridge (2017), London Bridge and Borough Market (2017), Manchester Arena (2017). The current threat comes primarily from Islamist extremism and lone actor attacks. This is the backdrop against which London events are planned.
The specific risk to corporate events is lower than the national threat level implies for most events. The vast majority of London corporate conferences proceed without incident. However, the threat is real, and the Terrorism (Protection of Premises) Act 2025 (Martyn’s Law) will give organisers of larger venues and events duties that go beyond hiring a door supervisor.
Planning for London events
The UK has a developed private security regulatory framework. All close protection officers must hold a current SIA licence. Paying someone to work in security without the right SIA licence can lead to a fine or prison. Our operator network holds current SIA close protection and door supervisor licences as a minimum.
Vehicle exclusion is a standard consideration for London events in central locations. The 2017 vehicle ramming attacks demonstrated that vehicle access management is an operational requirement rather than an aesthetic choice.
For events on politically sensitive topics, protest risk assessment is part of the planning process. London’s protest culture is active and Protected protests can affect venue access and event logistics. For the wider security picture, see our London city security briefing, and our event security service for how we structure protective coverage.
What does event security in London cover?
Terrorism-Aware Venue Assessment
The FCDO terrorism threat level for the UK is SEVERE. Our venue assessment reviews vehicle exclusion, blast standoff from the street, access control hardening, and emergency evacuation. These are not hypothetical considerations in London.
SIA-Licensed Close Protection
All close protection officers hold current Security Industry Authority (SIA) close protection licences. This is a legal requirement in the UK. We do not work with unlicensed operators.
Access Control
Credentialed entry management with ID verification. For high-profile events, this includes vehicle screening and electronic detection. London's corporate event security standards are well-developed; we work within established frameworks.
Counter-Terrorism Awareness
Event staff briefings on recognising suspicious activity, vehicle exclusion management, and emergency response procedures. Martyn's Law, the Terrorism (Protection of Premises) Act 2025, may apply to your venue or event once its duties take effect; we advise on what it will require.
Secure Event Transport
SIA-licensed security drivers for VIP and executive transfers. London event transport includes awareness of current police operations, protest routing, and access restrictions.
Protest and Disruption Management
London is an active city for organised protest. For events on politically sensitive subjects, we assess protest risk and provide crowd management capability that complies with UK public order law.
Vetted operators. Local knowledge. Proven protocols.
