Free SIA security mock test
Fifty questions in 75 minutes on licensing law, searching, drugs, weapons, crime scenes and queue control, with the reason behind every answer.
Each attempt picks a new set of questions from a bank of 64, so you can practise as often as you like.
Suspicion does not create a power of search. Refusing a search inside the venue is normally a breach of the conditions of entry, so the person can be asked to leave. Pass what you saw to the manager and the police if appropriate.
A wand lets staff check for metal weapons quickly and with little physical contact, which is less intrusive for the customer. It does not detect drugs, and the customer's consent is still needed.
Being open about recording is required by data protection guidance and often calms the situation. Announce it, keep recording until the incident is over and make sure the camera's light or sign is visible.
The small folding pocket knife exemption does not cover knives whose blade locks. Carrying a lock knife in public needs a good reason, and a night out is not one. Follow the venue policy and consider informing the police.
Fire exits must never be locked, wedged or obstructed while people are on the premises. Blocking an exit breaks fire safety law and could cost lives. Offer a safe alternative and record what you were asked to do.
Consent can be withdrawn at any point. If it is, the search must stop. Continuing without consent would be an assault. He can be refused entry, and his behaviour may be worth recording.
Acceptable proof of age is an original document such as a passport, a photo driving licence, or a PASS hologram card. Images on a phone cannot be checked properly and should not be accepted.
A venue must know how many people are inside at all times so it never goes over capacity and so the fire service can be told the number in an emergency. Count people out as carefully as you count them in.
The question bank has 64 questions across these topics. Every attempt mixes them at random.
The door supervisor unit is the one paper on the course that is about licensed premises specifically. Expect questions on the Licensing Act 2003, what a personal licence holder and a designated premises supervisor are responsible for, the proof of age documents you can accept, and when you must refuse entry or service. The rest of the paper is about the practical side of the job: how to search with consent, what to do with drugs or a weapon you find, how to protect a scene until the police arrive, and how to count people in and out safely.
Most questions describe a short situation and ask what you should do first, or which law applies. The wrong options are the things people do when they panic, so the test rewards calm reading. Each explanation tells you why the right answer is right, which is the part worth remembering.
Start with practice mode, where you see the answer after every question. When you are scoring well, sit the full 50 question test against the clock. Do that twice without dropping under 80 per cent and the real paper should hold no surprises.
Unit 2 of the Door Supervisor qualification covers the job on the door: the Licensing Act and the four licensing objectives, refusing entry, searching people and their property, drugs and weapons, preserving a crime scene, queue and capacity control, and the use of radios and body worn cameras.
The pass mark is 70 per cent, so 35 correct answers out of 50. The real paper gives you 75 minutes, and so does the full practice test here.
No. The real papers belong to the awarding bodies and are never published. These questions were written by London SIA Course from the SIA's learning outcomes for the unit, in the same multiple choice format, so they test the same ground.
Three more. Unit 1, the principles of working in the private security industry, conflict management and physical intervention. Each has its own practice test on this site.
Yes. The SIA requires an Emergency First Aid certificate before you can take the Door Supervisor course, and ours includes it on the first day.
Questions last checked: 20 October 2026. These are practice questions written for London SIA Course, not the official exam papers.
