From 1 December 2025, the Security Industry Authority (SIA) will introduce updated conditions and decision-making criteria for SIA licensing. These changes represent a significant development for the private security sector and reinforce the regulator’s commitment to raising standards across the industry.

The revised criteria will introduce a tougher approach to criminality, strengthening the way previous convictions and relevant conduct are assessed when determining whether an individual is suitable to hold a licence. In addition, the SIA will provide greater transparency around the broader “fit and proper” test that all applicants and existing licence holders must satisfy. This test considers not only criminal history but also overall conduct, integrity, and suitability to operate within positions of trust.

One of the key updates includes the expansion of the list of criminal offences that the SIA will consider relevant when making licensing decisions. By widening this scope, the regulator aims to ensure that only individuals who meet the highest standards of professionalism and responsibility are permitted to work within the regulated security environment.

For security providers and licence holders alike, these changes highlight the importance of maintaining compliance, professionalism, and ongoing due diligence. At the McKenzie Arnold Group, we welcome measures that enhance public confidence and reinforce the integrity of the sector. We remain fully committed to supporting our staff through clear guidance, continuous training, and robust recruitment processes to ensure full compliance with SIA standards.

As the industry evolves, maintaining high standards is essential to safeguarding the public and protecting the reputation of professional security services. The upcoming changes serve as a timely reminder that trust, accountability, and transparency remain at the heart of effective security provision.
