Holding more than one SIA licence is common in the security industry, and for good reason. Pairing a Door Supervisor licence with a CCTV licence, for example, means you’re not limited to one type of shift or one type of venue. But it also raises practical questions: do you need to retrain from scratch, and does it cost double?

Here’s what you need to know before booking a second course.

What SIA Licences Work Well Together?

Jobs within the security industry often overlap, and so do the licences. The most common and strategic pairing is the Door Supervisor licence with the CCTV licence, and we also see a lot of Close Protection holders adding CCTV to their portfolio.

Do I Have To Do the Whole Course Again?

The courses are very different for the Door Supervisor and CCTV Operative badges, so yes, you will need to attend the full course. The CCTV Operative course has hands-on learning with equipment, and the Door Supervisor course has physical intervention practical parts.

The good news is that Unit 1 – Working in the Private Security Industry – is shared across the Door Supervisor, Security Guard, and CCTV Operator courses, so you don’t always need to sit it twice.

To claim the exemption, you must hold a valid Door Supervisor, Security Guard, or CCTV qualification certificate issued after April 2021. Refresher and Top-Up certificates are not accepted as evidence for this exemption – it must be your original qualification certificate.

Will It Be Expensive?

The price of a second licence can put people off, but the Security Industry Authority has made it more affordable. The standard fee for an SIA licence application is £204, and if you already hold a valid licence, you may qualify for a 50% discount on an additional licence – bringing it down to £102. As of June 2026, this discount only applies if the additional licence is applied for on the same day and on the same application as your first.

Is It Worth It?

If you’re already weighing up whether the Unit 1 exemption applies to you, it’s worth remembering the bigger picture: holding a second SIA licence makes you more employable and easier to schedule across shifts, since employers would rather book one multi-skilled worker than two specialists.

Start Working In Security

Whether you’re getting your first SIA licence or adding a second one, the process is the same: complete the right course, then apply for your licence once you’ve passed. Door Supervisor, Security Guard, CCTV Operator, and Close Protection each have their own training route, but as covered above, you may not need to repeat every module if you already hold a qualification issued after April 2021.
