Cover pages of the SIA door supervisor refresher question bank, with the summary of the exam

168 original practice questions for the two SIA door supervisor refresher knowledge papers (England and Wales), each with the answer, an explanation and the law or guidance it relies on.

This pack is for door supervisors renewing an SIA licence. Since 1 April 2025 you must hold a refresher qualification before you can renew, and the refresher has two multiple-choice knowledge papers. It has 168 original questions, written by Plainfiles from the published refresher specification and GOV.UK guidance and from the legislation: searching, keeping vulnerable people safe, terror threats and spiking for Unit 1, and the knowledge side of physical intervention for Unit 2. Some questions on Martyn’s Law, the renewal rule and the first aid requirement are extra practice outside the assessment criteria and are left out of the mock papers. The law covered is that of England and Wales only.

In Pearson’s refresher specification (Issue 2, November 2025), Unit 1 has 35 questions in 55 minutes with a pass mark of 25 (71 per cent) and Unit 2 has 30 questions in 45 minutes with a pass mark of 24, which is 80% (Pearson); check with your awarding organisation, because question counts, times and pass marks can differ between awarding organisations. The self-marking quiz draws a timed mock paper for each unit. The practical assessments (searching and the physical intervention techniques) and the first aid qualification are not covered. The SIA consulted in 2026 on new specifications, with new qualifications planned for later in 2027; this pack follows the current refresher specification.

Formats: Two A4 PDFs (question bank, and answers and notes) and one self-marking HTML file that opens in any modern web browser and works offline.

Version 1.0.0, checked 9 November 2026. Updates to this version are free.

What is included

What it is not

  • These are original practice questions, not the real exam. The real papers are set by an awarding organisation and will word their questions differently, and passing these questions does not guarantee a pass.
  • The questions are not from the SIA or any awarding body. The pack is not issued, endorsed or checked by the SIA, an awarding body or a training centre, and it contains no questions from any real paper or sample paper.
  • It covers the law of England and Wales only. Scotland and Northern Ireland have different arrest, licensing and drug law, and this pack does not adapt the content for them.
  • It is for renewing a licence. If you are training for your first licence, you need the first-time question bank instead.
  • It is not legal advice. The law changes, so check the sources before you rely on an answer.
  • It does not book your training or the exam, and it does not apply for your licence. You take the course and the assessments with a training centre, and you apply to the SIA yourself.

Five sample questions from the bank

Copied word for word from the 168 questions in the kit. None of them is one of the 25 free ones. Pick an answer, then open it to see the explanation and the source.

Sample question 1

Unit 1, topic 1: Searching

Why is it good practice to search in a dedicated area, in view of CCTV and with a colleague or witness?

  1. It avoids any need for a search register, because CCTV records the whole search
  2. It lets staff keep anything of low value that they find, as long as the witness agrees to it
  3. It makes the search faster, because the witness can check the person’s bags
  4. It protects the person searched and the door supervisor from allegations of misconduct
Show the answer

Answer D. It protects the person searched and the door supervisor from allegations of misconduct

Searching in view of CCTV or with a witness gives protection against allegations of misconduct and provides evidence.

Relies on: Refresher Unit 1 AC 1.5 (SIA-required unit content, Pearson BTEC refresher specification, Issue 2, Nov 2025).

Sample question 2

Unit 1, topic 3: Terror threats

A door supervisor finds an unattended bag near the entrance. What does the “HOT” protocol help them decide?

  1. Whether the owner is Hurt, Ordinary or Tired, judging by their behaviour
  2. Whether the entrance is Hot, Open or Tidy enough for a safe search
  3. Whether the item is Heavy, Old or Torn, compared with other bags in the area
  4. Whether the item is Hidden, Obviously suspicious or Typical for the location
Show the answer

Answer D. Whether the item is Hidden, Obviously suspicious or Typical for the location

HOT stands for Hidden, Obviously suspicious and Typical. If an item still looks suspicious after applying HOT, call 999.

Relies on: ProtectUK, HOT protocol, https://www.protectuk.police.uk/advice-and-guidance/awareness/other-threats.

Sample question 3

Extra practice, not in the refresher papers: Martyn’s Law and renewal rules

What first aid requirement applies before starting door supervisor refresher training?

  1. A first aid qualification that is valid for at least another five years from the start
  2. No first aid qualification is needed in order to start the refresher training course
  3. A current first aid qualification that stays valid for at least another 12 months
  4. A first aid qualification that was gained in the seven days before the course starts
Show the answer

Answer C. A current first aid qualification that stays valid for at least another 12 months

GOV.UK says you must hold an up-to-date Emergency First Aid at Work qualification or equivalent, valid for at least another 12 months, and show it to your training provider.

Relies on: GOV.UK, Check what training you need to get an SIA licence, https://www.gov.uk/guidance/check-what-training-you-need-to-get-an-sia-licence.

Sample question 4

Unit 2, topic 1: Legal and professional implications

What are the professional implications of using physical intervention?

  1. Only the police are affected, because they decide whether force was lawful and nobody else has any consequences
  2. Only the venue is affected, through loss of money from claims, because the individual operative has no liability
  3. None, because a valid SIA licence and the employer’s insurance protect the operative from every claim, complaint or disciplinary action
  4. Following sector guidance and standards, ethical and employment consequences, and the possibility of financial claims
Show the answer

Answer D. Following sector guidance and standards, ethical and employment consequences, and the possibility of financial claims

Professional implications include sector-specific legislation and guidance, ethical issues, financial implications and the need to treat intervention as a last resort.

Relies on: Refresher Unit 2 AC 1.2 (SIA-required unit content, Pearson BTEC refresher specification, Issue 2, Nov 2025).

Sample question 5

Unit 2, topic 3: Reducing risk and good practice

What is the effect of strikes and kicks in a physical intervention?

  1. They can cause serious injury or death
  2. They are the safest option available
  3. They carry little risk to the person
  4. They help the person to calm down
Show the answer

Answer A. They can cause serious injury or death

Serious injury or death can result from strikes and kicks, falls to the ground, interventions involving the neck, spine or vital organs and restraint on the ground.

Relies on: Refresher Unit 2 AC 3.3 (SIA-required unit content, Pearson BTEC refresher specification, Issue 2, Nov 2025).
