If you are already working as a licensed door supervisor, you already know how demanding the role can be. But staying on top of your SIA licence renewal obligations is just as important as staying sharp on the job. The Door Supervisor Refresher Training is the course that keeps you legal, up to date, and confident in your skills   and it is a mandatory requirement for SIA licence renewal.

This article covers everything you need to know about the refresher course, what it includes, and why completing it with a trusted London provider like Betrain makes all the difference.

What Is Door Supervisor Refresher Training?

The Door Supervisor Refresher Training is a mandatory course for existing SIA Door Supervisor Licence holders who need to renew their licence. The SIA requires that all licence holders complete this training as part of the renewal process, demonstrating that they remain competent, current, and safe to operate in the security industry.

This is not a repeat of the full Door Supervisor course. Instead, it is a focused update that covers the latest developments in safety techniques, legislation, and professional practice   giving you everything you need to renew with confidence.

Why Is the Refresher Course Mandatory?

Security is a constantly evolving industry. Physical intervention methods are regularly reviewed to reduce harm and liability. UK licensing laws are updated to reflect new case law and government policy. Venue safety expectations continue to rise in response to real-world incidents.

The SIA requires refresher training to ensure that every licensed door supervisor in the UK is operating at a current standard   not relying on knowledge that may be years out of date. Without completing the refresher, you cannot legally renew your licence and continue working.

When Should You Book Your Refresher Training?

Most professionals recommend booking your Door Supervisor Refresher Training within the final 12 months of your current SIA licence. This gives you enough time to complete the course, process your renewal application, and avoid any gap in your licence coverage.

Do not leave it to the last moment. The SIA licence renewal process takes time, and delays can mean a period during which you are unable to work legally.

What Does the Door Supervisor Refresher Course Cover?

The refresher course at Betrain covers six key areas, all essential to maintaining safe and professional door supervision practice.

Physical Intervention Skills:   You revisit and refine your knowledge of legally compliant physical intervention techniques, including escorting, disengagement, restrictive intervention, and managing high-risk situations safely. Particular attention is given to minimising positional asphyxia risks, which represent one of the most serious dangers in physical restraint situations.

Conflict Management and De-escalation:   Updated strategies for identifying aggression triggers early, using verbal and non-verbal communication to reduce tension, and defusing situations before they turn physical. The course also covers how to manage intoxicated or vulnerable individuals, which represents a significant portion of real-world door supervision challenges.

Protecting Vulnerable Individuals:   Door supervisors have a duty of care toward vulnerable people, including those who are intoxicated, under the influence of substances, victims of harassment, or experiencing emotional distress. This module ensures you know how to identify and respond appropriately.

Emergency and Evacuation Procedures:   A refresher on fire evacuation, first aid awareness, emergency communication, and how to work effectively with emergency services during a serious incident.

Updated SIA Legislation:   Coverage of current UK laws regarding use of force, self-defence, health and safety obligations, GDPR, and venue licensing duties. Staying legally informed protects both you and your employer.

Professional Standards and Behaviour:   Reinforcement of customer service expectations, ethical conduct, equality and diversity awareness, and teamwork within a security setting.

How Long Does the Refresher Course Take?

The Door Supervisor Refresher Training is typically a one-day course. It includes both practical assessments   such as scenario-based exercises and physical intervention demonstrations   and a short written test. Most experienced door supervisors find the course straightforward, particularly if they have been actively working in the industry.

What Do You Receive After Completing the Course?

Once you pass all assessments, you receive a certificate of completion. This certificate is submitted as part of your SIA licence renewal application, confirming that you meet the updated competency requirements. With your certificate in hand, you can proceed with your renewal and continue working without interruption.

Is the Refresher Course Difficult?

No. The course is specifically designed for people with security experience. If you have completed the full Door Supervisor course and have been working in the industry, the refresher will feel familiar   because it is building on knowledge you already have, not teaching from scratch.

Bertain’s instructors are experienced professionals who guide you through all the content clearly and practically. Small class sizes also mean you have the opportunity to ask questions and work through scenarios in detail rather than being lost in a large group.
