Compliance 2025
The Protection of Premises Act 2025 (Martyn’s Law) requires qualifying venues in London with a capacity of 200+ to implement documented security plans, staff awareness training, and appropriate physical security measures. London has one of the highest concentrations of qualifying venues in the UK. DSS security guards are trained in counter-terrorism awareness (CT ACT) and can form part of a compliant security plan.
The UK’s national terrorism threat level is currently assessed as SEVERE — meaning an attack is highly likely (MI5, 2025). Against this backdrop, the Protection of Premises Act 2025 (Martyn’s Law) places a direct legal duty on qualifying London venues to implement documented security plans.

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.
