UK law sets no statutory ratio for event security staffing, so any provider quoting you a legal minimum is quoting something that does not exist. The common planning benchmark sits at 1 SIA-licensed officer per 100 to 150 guests, tightening where alcohol is served, the crowd stands rather than sits, or the site spreads across multiple zones. Useful as a starting figure. Not an answer.
What binds you is the condition written into your premises licence or Temporary Event Notice. Where that document states a minimum number of SIA staff, the figure is a floor rather than a target, and a Safety Advisory Group minimum overrides any industry ratio outright. We read the licence, survey the site, then size the team against both. A seated awards dinner on the seafront and a standing crowd of the same size carry entirely different risk.
Every officer holds a valid SIA licence, verified against the SIA public register before deployment with the result logged. A card shown at the gate on the day is not a check. Category matters as much as validity: a Door Supervisor licence covers venues licensed for alcohol, a Security Guard licence covers premises without one, and deploying the wrong category into a licensed room becomes the licence holder’s problem as well as the officer’s.
Through our sister company, staff access advanced SIA training in crowd management, conflict resolution, first aid and event procedures. Officers hold Emergency First Aid at Work certification, so someone going down in a crowd gets a trained responder before the ambulance reaches the gate.
Alpha Security Services holds a 98% client retention rate across its contract base. Organisers rebook because incidents get handled quietly and the report afterwards reads clearly enough to forward to an insurer without rewriting it first.
Incidents are handled by the officers already standing on your site, with supervision escalating to Sussex Police where the situation calls for it. Our 24/7 Security Operations Centre tracks officer positions by GPS throughout the shift, which matters most on a site spread along a seafront or across a parade route, where the nearest officer is rarely the one you expect. Real-time digital incident reporting carries something logged at a far barrier into the control room in seconds.
Late bookings mobilise across Brighton within 24 to 48 hours.
Event security in Brighton is priced against the deployment: guest count, venue, hours, licence conditions and the mix of licence categories the site calls for. We scope against the survey rather than quoting a headcount and hoping it stretches. You pay for the officers, stewards, supervisors and cameras the event actually uses.
Officers carry body-worn cameras and two-way radios, with patrol logging recording each check as it happens rather than at the end of the night. A 24/7 Security Operations Centre sits behind them, tracking every officer by GPS.
Rapid Deployment CCTV goes in where a site needs fixed surveillance, wired directly to the operations centre. It suits long open perimeters and seafront ground, where a camera covering a quiet stretch costs less than an officer standing on it until 3am. All footage is captured, stored and handled in line with UK GDPR.

Officers turn out clean, speak clearly with guests and venue staff, and work inside your venue’s own procedures rather than around them. GPS confirms patrols were completed, and body-worn footage gives you evidence that holds if an incident reaches a claim or a court. A bespoke uniform option puts officers in black tie or branded kit where the dress code calls for it.

Our event work spans licensed and unlicensed venues, enclosed sites and open ground, ticketed audiences and free public crowds. That range decides what the survey looks for: ingress and egress points, pinch points on the approach, bar positions, barrier lines, vehicle movements during build and de-rig, and the hours when a site holds equipment but no public. Brighton sites vary sharply, from a stadium bowl at Falmer to a parade route running several miles through live streets, and the deployment follows the ground rather than the guest list alone.

Cover holds from build through to clear-down, including the hours either side when staging, sound equipment and stock sit unattended. GPS tracking keeps every position visible in real time, so gaps close while the event is still running. The standard on a 2am door in the Lanes matches the standard on a daytime family event at Preston Park.

“We had a Brighton event spread across several areas rather than one enclosed venue, so keeping the security team coordinated was important. Alpha managed the different access points well and stayed responsive as crowd movement changed through the day.”
“Our event involved guest searches, alcohol service and several restricted zones, so we needed a team that understood both the licensing requirements and the practical side of running a busy venue. Alpha handled the entrances professionally and worked closely with our management team.”
“We needed security from the build period right through to clear-down because equipment was being left on site before and after the public hours. Alpha covered those quieter periods properly and gave us confidence that the site was protected throughout.”
Alpha Security Services covers Brighton and Hove and the surrounding area, with officers, stewards and supervisors drawn from a regional network rather than one fixed base. Brighton and Hove sit within a single city and a single licensing authority, so a venue in Hove and a venue on the seafront answer to the same council, which keeps the licensing route the same wherever your event sits in the city.
Hire licensed security where your event involves alcohol, ticketing, restricted areas or a crowd that needs managing, because those activities are licensable and the licence holder carries the liability. Brighton & Hove City Council attaches security conditions to premises licences and Temporary Event Notices, and larger events go before the Safety Advisory Group before they run.
One point the security industry keeps getting wrong. Martyn’s Law, the Terrorism (Protection of Premises) Act 2025, is not yet in force. Royal Assent came on 3 April 2025, the Home Office published section 27 statutory guidance on 15 April 2026 and updated it on 18 May 2026, and commencement is signalled for spring 2027 at the earliest. Standard duty requirements begin at a capacity of 200, with further requirements above 800, and the SIA takes the regulator role. Nothing obliges you to comply today. Planning against the requirements now avoids a scramble when the date lands.

The planning benchmark is 1 SIA-licensed officer per 100 to 150 guests, tightening where alcohol is served or the crowd stands rather than sits. No statutory ratio exists in UK law, so the real figure comes from your premises licence condition, any Safety Advisory Group minimum and the site survey.
Only those carrying out licensable activity. Searching guests, refusing entry or ejecting someone at a venue licensed for alcohol requires a Door Supervisor licence, while a steward giving directions does not. Mixing the two on one plan is a common reason licensing officers push back.
Each venue keeps its own premises licence, its own capacity and its own door team, so a shared wristband does not create a shared limit. Cover is planned venue by venue, with counting in and out at each room and a supervisor holding the overall picture across the programme.
Yes. Open street events are stewarded along the route rather than at a perimeter, with officers on junctions, crossing points and any vehicle access left live. Numbers are set against route length and expected footfall instead of a gate count, and the plan works alongside the road closures the council puts in place.
Rules differ at a designated ground holding a safety certificate. In-house stewards are exempt from SIA licensing under section 4(6) of the Private Security Industry Act 2001 where trained and vetted to the equivalent standard, but agency stewards carrying out licensable work must hold a Door Supervisor licence.
Every officer holds a valid SIA licence, checked against the SIA public register before deployment with the result logged. Each is also vetted with criminal record checks and identity confirmation.
Cost depends on guest count, venue, hours, alcohol service and the licence categories the deployment needs. A 200-guest function and a multi-thousand-capacity outdoor event sit far apart, so we quote against the survey rather than a flat rate.
Short-notice cover goes live within 24 to 48 hours. For planned events we build the team around your schedule so officers are in position before doors open.
Yes. Rapid Deployment CCTV links to our 24/7 Security Operations Centre and suits stretches where surveillance matters but a static officer is not cost-justified. On open seafront sites with long perimeters, cameras often carry the quiet ground while officers work the entries.
Yes. Close protection officers cover performers, speakers, sponsors and public figures from arrival through to exit, working alongside a guest’s own team where one exists.
On-site supervision handles it first, escalating to Sussex Police where the incident calls for it, with the Security Operations Centre tracking officer positions throughout. You receive a written incident report, with body-worn footage retained for evidential use.
