What You Should Know About Event Security in 2025

Living in the UK, especially in London, you know how things are. Safety is a big deal now, more than ever. And 2026 has been the year it stopped being a background concern for event organisers and became a planning item with a deadline attached to it.

Two things changed. In April 2026, the Home Office published the final statutory guidance for Martyn’s Law, which means venues and organisers now know exactly what will be expected of them. And on 30 April 2026, the Joint Terrorism Analysis Centre raised the UK national threat level from substantial to severe, meaning an attack is assessed as highly likely rather than likely.

The numbers back up the mood. There were 255 terrorism-related arrests in Great Britain during 2025, a 2% rise on the 250 recorded the year before. At the end of 2025 there were 267 people in custody for terrorism and terrorism-connected offences, the highest figure since comparable records began.

So whether you are running a concert, a football fixture, a food festival or a corporate AGM, event security is no longer a box you tick two weeks out. It is part of the plan from day one.

The duties are not enforceable yet. But the guidance is out, and the SIA is the regulator, so there is no longer any excuse for waiting. If your event is in scope, spring 2027 is roughly one full event season away.

Who is in scope. The standard tier covers premises and events with a public capacity between 200 and 799. Those responsible must register with the SIA and put written procedures in place covering evacuation, invacuation, lockdown and emergency communication. Above 800 capacity you move into the enhanced tier, with heavier obligations including documented risk assessments and protective measures.

What it costs to get it wrong. Standard tier non-compliance carries penalties of up to £10,000. Enhanced tier penalties go up to the greater of £18 million or 5% of global revenue. Around 155,000 standard-tier and 25,000 enhanced-tier premises are expected to fall within scope across the UK.

One point worth being clear on: the legal duty sits with the operator of the premises or event, not with your security contractor. But in practice you cannot evidence compliance without your security provider’s paperwork. The briefing sign-offs, licence verification records, stewarding headcounts at each entrance and incident reports are all part of your compliance file. If your current provider cannot hand you that documentation as a matter of routine, that is a problem you want to find out about now rather than in 2027.

When we talk about event security services, we are not just talking about a few people on the door. It is a full plan. It covers crowd management, entry screening, surveillance, traffic control and emergency response. Security teams are there to spot problems before they start, not just to deal with them once they have.

Having a trained team on site also changes how people feel. Visible security gives your guests reassurance. Guards at entrances, CCTV coverage, bag checks, all of it sends a message that the event is being run properly. And it only takes one weak point to undo the rest.

One legal point people still get wrong: in the UK, anyone carrying out security guarding or door supervision at an event must hold a valid SIA licence under the Private Security Industry Act 2001. Hiring unlicensed personnel is a criminal offence, and the liability lands on you as the organiser. Always ask your provider to show you licence verification against the SIA register before deployment.

What do event security teams actually do?

A lot of people assume they just stand around. The real job is keeping everyone safe while the event runs smoothly, and there is more to it than it looks.

Once people start arriving, the team controls the flow. They check bags, read body language and keep eyes on the crowd, catching things early before they become incidents. You will see them at gates, near the stage, or moving through the crowd. That is deliberate. They need to blend in but stay easy to reach.

It is not all about trouble, either. Someone faints, they are on it. Someone is lost, they help. They handle a long list of things most attendees never notice, and they do it without making people feel watched.

The main event security threats in 2026

Terror attacks

Large crowds are, by their nature, a target. With the national threat level now at severe, this is the risk that has moved up everyone’s list this year. Preparation is not just about staffing the gates. It is about knowing what to look for, having a plan your team has actually rehearsed, and being able to act in seconds rather than minutes. These incidents remain rare, but the consequences are severe enough that planning ahead is non-negotiable.

Violence and aggression

Fights are still one of the most common problems at events. Sometimes it is rival fans, sometimes it is alcohol. It usually starts small, with pushing or shouting, and escalates fast. Trained officers who can read the warning signs and step in early prevent most of it from ever becoming an incident.

Theft

Crowds are ideal cover for thieves, who often work in groups and move quickly. Visible security in high-traffic areas, combined with CCTV and bag checks, stops most of it before it starts.

Fire hazards

Overheating cables, open flames at food stalls, a dropped cigarette in the wrong place. In a packed space, a small fire creates panic within seconds. Fire exits need to be clear, extinguishers need to be findable, and staff need to know their roles before the doors open.

Crowd control issues

Poor layout or under-staffing turns an exciting crowd into a dangerous one. People push, rush exits, or panic if they feel trapped. You need the right layout, clear entry and exit points, and trained staff who can guide people calmly. Read more on event crowd management and how it differs from crowd control.

Types of event security services

Event stewards manage the crowd, give directions and monitor for problems. Many hold NVQ Level 2 Spectator Safety qualifications.

Event crew handle build and breakdown: stage, lighting, fencing and equipment. Their work makes the space safe before anyone arrives.

Pit crew work front of stage, managing barriers and crowd surge and pulling people out when they are in trouble.

Traffic marshals manage vehicle access, car parks and loading bays, and keep emergency routes open.

First responders provide on-site medical cover, scaled to the size and risk profile of the event.

Response officers deal with incidents directly: altercations, rule breaches, safety issues.

Planning and consultancy

Event consultancy covers the work that happens before anyone arrives on site.

• CAD drawings map the site: stages, exits, cameras and staff positions.
• Capacity calculations set safe numbers for each area based on space and exit capacity.
• Stewarding dot plans show where each steward stands and what they are responsible for.
• Event security planning pulls it together: roles, emergency procedures, communications.
• Queue management designs place barriers, staff and signage to keep entry calm.
• Event risk assessments list what could go wrong and what you will do about it.
• Rapid deployed CCTV gives you a mobile control room with live site coverage.
• Barrier designs guide movement and form part of the evacuation plan.

Most of these documents are also what your Safety Advisory Group will want to see, and increasingly what your insurer will ask for.
