A company picks its own codes, up to four, and Companies House does not check them, so 80100 is the company's own description of what it does, and 11,384 list it first where 14,465 list it anywhere.

No. SIC codes are self-declared at Companies House and nobody vets them. Security Industry Authority licensing applies to individuals doing licensable roles, such as guarding and door supervision. The voluntary Approved Contractor Scheme applies to businesses. A company can sit under 80100 and hold no licences at all. Check SIA status separately from the public record.
