The number of questions varies by qualification. For the popular Door Supervisor licence, the exam typically consists of 72 multiple-choice questions spread across three units. The Security Guarding exam is slightly shorter, while the CCTV Operator exam has its own distinct set of questions. Each unit has a pass mark of 70%, and you must pass all units to gain the qualification.

The SIA test is designed to be challenging but is very passable with proper preparation. The difficulty often lies in the specific wording of questions and the need to apply knowledge to real-world scenarios. Using a high-quality online practice test is the best way to familiarize yourself with the format and question style, which significantly reduces the perceived difficulty on exam day and builds confidence.

To pass the SIA exam on your first attempt, you must fully engage with your training course and supplement it with self-study. Consistently use a reliable online practice test to identify and strengthen weak areas. Focus on understanding the core principles behind the laws and procedures, not just memorizing answers. This deeper comprehension is the key to answering situational questions correctly and achieving a first-time pass.

The cost of the SIA exam itself is almost always included in the price of your SIA-approved training course. Course fees vary by provider and location, typically ranging from £180 to £350. It's important to note that the separate SIA licence application fee, which you pay directly to the SIA after passing your exam, is a standard £184 for a three-year licence as of early 2026.
