The Security Industry Authority (SIA) sets the standards for security professionals to ensure they have the skills and knowledge to perform their roles effectively. At Stonewall Security, we pride ourselves on all our security personnel being SIA-trained and accredited. Not only do all of our officers have an SIA licence, meaning they are trained to the highest quality, but our team’s experience is also reinforced by regular ex-police officer-led training. Whether you’re looking to get your first license or need to renew your existing one, understanding the SIA course costs in 2025 is essential.
