Working as a door supervisor in the UK is both a privilege and a responsibility. The security industry is fast-paced and ever-evolving, which is why the SIA (Security Industry Authority) requires professionals to maintain their knowledge and stay updated through recognised training. Two key qualifications that often come up in this context are the SIA Top-Up course and the SIA Door Supervisor course.
Whether you're new to the industry or an experienced professional looking to renew your licence, this blog will help you understand the differences, requirements, and benefits of both.
 
What Is the SIA Door Supervisor Course?
The SIA Door Supervisor course is the initial training you need to obtain a door supervisor licence in the UK. This course is essential for those who want to work in roles such as nightclub security, retail guarding, event safety, and any environment where protecting premises, property, or people is required.
The course ...
... typically covers the following units:

Working in the Private Security Industry
Working as a Door Supervisor
Conflict Management
Physical Intervention Skills

The training generally takes four to six days and includes both written and practical assessments. Once you pass the course and receive your qualification, you can apply for an SIA licence to legally work in the sector.
 
Why Take the SIA Door Supervisor Course?

Legal Requirement
You cannot work legally as a door supervisor without this qualification and the corresponding SIA licence.
Versatile Job Roles
This licence allows you to work in a range of environments—from nightclubs and shopping centres to festivals and sporting events.
Enhanced Responsibility
Door supervisors are often the first line of defence in preventing incidents, so comprehensive training is essential.
Career Progression
Many professionals use this course as a stepping stone to other roles such as security management or close protection.

 
The Introduction of the SIA Top-Up Course
If you already hold a door supervisor licence and it was issued before April 2021, you must complete the SIA Top-Up course before you can renew your licence.
This was introduced in response to updated regulations by the SIA, aimed at ensuring all licence holders are trained in new areas of security concern, such as:

Counter-Terrorism Awareness (CTSA)
Updated Physical Intervention Techniques
First Aid Requirements (Emergency First Aid at Work)

The SIA Top-Up course is typically a one or two-day programme. It’s shorter than the initial course, but it is mandatory if you want to continue working legally in the UK’s security industry.
 
What’s Included in the SIA Top-Up Course?
This training includes:

Terror threat awareness training
Updated conflict management practices
Revised physical intervention content
Practical assessments for physical skills and scenario-based questions

Note: You’ll need a valid Emergency First Aid at Work (EFAW) certificate before attending. Many training centres offer a bundled package with both the EFAW and the Top-Up course on the same day or over two days.
 
Who Needs to Take the Top-Up Course?
If you:

Hold a door supervisor licence that was issued before 1st April 2021
Are looking to renew your SIA licence
Want to stay compliant with new SIA requirements

… then the SIA Top-Up course is essential.
Failing to complete this course before applying for renewal may result in your licence being delayed or rejected.
 
Choosing the Right Training Provider
Whether you're taking the full SIA Door Supervisor course or the SIA Top-Up course, it’s vital to select a training provider that is:

SIA-approved
Transparent about course content and pricing
Offering flexible dates and locations
Known for high pass rates and qualified instructors

Some centres even offer weekend or fast-track options to accommodate working professionals.
The UK’s private security industry is built on professionalism, updated knowledge, and legal compliance. By completing the SIA Door Supervisor course, you lay the foundation for a successful and rewarding career in security. And by enrolling in the SIA Top-Up course at the right time, you keep your licence current and your skills relevant.
Whether you’re new to the industry or renewing your qualifications, investing in the right training is crucial for long-term success.
