Do security officers have more powers than the public?

No. In most situations you have the same powers as any other citizen. Your SIA licence lets you work in a licensable role but gives no extra power to arrest, search or use force.

Can a security officer arrest someone for any crime?

No. In England and Wales, section 24A of PACE covers only indictable offences, and only when arrest is necessary for a listed reason and a constable cannot reasonably do it instead.

Can I search a customer who refuses?

No. Security staff can only search with consent, often as a condition of entry. If the person refuses, you can refuse entry, but you cannot force a search.

Does this course let me work as a security officer?

No. Front line security work in the UK needs a licence from the Security Industry Authority (SIA), which needs a licence-linked qualification from an approved training provider. This course is background knowledge only.
