The Security Industry Authority (SIA) has not to date specified competency requirements for second and subsequent licence applications after an individual has provided evidence of competency when applying for his or her first licence under the Private Security Industry Act 2001. However, the SIA anticipate proposing the introduction of a requirement for licence holders, including door supervisors, to provide evidence that they have kept their competency up to date when applying for licence renewal. Such a proposal would require an assessment of the costs and benefits involved.
