Defence Security Solutions is a London-based SIA Approved Contractor. We provide professional event security and trained stewards for events of every type and size across London and the United Kingdom — corporate launches, festivals, concerts, sporting events, weddings, and private parties.
Every deployment starts with a proper risk assessment. We write a formal security plan covering staff assignments, communication protocols, emergency evacuation procedures, and escalation routes. We brief every officer and steward before the event opens, and we liaise with venue management, production teams, and local authorities where required.
Crowd management, emergency evacuation, and customer service — directing flow, spotting hazards, no SIA powers required.
Real-time coordination across the venue with radio links to every officer and steward on the ground.
Site visit, layout review, access and egress mapping, and a formal written security plan before the event opens.
From product launches to festivals — we have the licences, the ratio planning, and the experience to get it right.
Corporate events need security that does not overshadow the occasion. Product launches, award ceremonies, conferences, and private dinners all require a professional, discreet approach across London.
Our festival teams include SIA-licensed officers, trained stewards, supervisors, and control room staff. We conduct full venue risk assessments before every London festival deployment.
Sporting events require an understanding of crowd behaviour, segregation requirements, and the legal framework for sports grounds in England — applied across London stadiums and venues.
Increasingly common at larger or higher-profile London events. Our officers work discreetly, manage guest lists, and protect gifts and valuables. Close protection available for the couple where required.
Private parties, club nights, charity galas, and one-off venue events across London all benefit from professional, discreet security tailored to the occasion.
Our London consultants build bespoke security plans for any site, sector, or requirement.
A well-run London event uses both in the right ratio for the event type and risk level.
SIA-licensed and legally empowered to use reasonable force, conduct searches, and remove individuals from your event. Essential for higher-risk venues, door control, VIP areas, and incident response.
Trained in crowd management, emergency evacuation, and customer service. They don't carry SIA powers but are essential for managing crowd flow, directing attendees, and spotting hazards before they escalate.
Protection of Premises Act 2025
The Protection of Premises Act 2025 (Martyn’s Law) requires qualifying venues in London with a capacity of 200 or more to implement a documented security plan, deliver staff security awareness training, and deploy appropriate physical security measures. London has one of the highest concentrations of qualifying venues in the UK — concert halls, conference centres, sports arenas, large retail spaces, and hospitality venues across the capital all fall within scope. DSS event security plans are built to meet the Act’s requirements as standard, not as an add-on. Our London consultants can advise whether your specific venue and event size qualifies, and produce a written plan that satisfies the legislation.

Whether you need a single officer on a retail floor or a full security operation across multiple sites, our team has the licences, the training and the experience to get it right. Every officer is briefed to your specific requirements before their first shift.
We hold full ACS status under reference DESESOSC02, independently assessed across 78 areas of business performance by the Security Industry Authority. This is not a membership or a self-declared standard — it is a formal quality assessment that relatively few UK security companies pass. You can check our status on the SIA register whenever you wish.
Almost all of our clients choose to stay with us. That is not something we achieved through aggressive account management — it is the result of officers who show up properly, operations that run without drama and account managers who actually respond when something needs sorting. We think that is the least a client should expect, and we work hard to make sure they get it.
Every officer we deploy has been screened under BS 7858 before they arrive on your site. That covers five years of employment history, criminal record checks, financial background and personal references. There are no shortcuts in our recruitment process because the people we put in front of your clients and staff are a direct reflection of us.
Our operations team is available 24 hours a day, seven days a week, including weekends and bank holidays. If something needs dealing with at two in the morning, there will be someone at Defence Security Solutions to pick up the phone.
We have been operating since 2015, which means we have spent twelve years learning what works, what does not and what clients actually need from a security company in London. That experience runs through every contract we manage, from a single static post to a large-scale multi-site operation.
Every client has a named account manager who knows their sites, their preferences and their expectations. You will not be handed between departments or left waiting for a callback — your account manager is your consistent point of contact throughout the contract.
With more than 900 trained, SIA-licensed officers across our operations, we have the capacity to respond to requirements of any size — a single post, a team deployment or a rapid response to an urgent request. Scale has never been a problem for us.
The Protect Duty — known as Martyn’s Law — will place new legal obligations on venues and events across the UK to have protective security measures in place. Our team is ready to help clients understand what those obligations mean in practice and how to meet them without overcomplicating things.
Event security costs in London typically range from £18–£28/hr per SIA-licensed officer, and £14–£20/hr for trained stewards, depending on event size, risk level, and duration. DSS provides free, itemised quotes based on a site visit and risk assessment. Call 0203 490 8070.
Event security officers are SIA-licensed and have the legal power to use reasonable force, conduct searches, and remove individuals. Event stewards are trained in crowd management and emergency evacuation but do not carry SIA powers. A well-run London event uses both in the right ratio for the event type and risk level.
