What standard tier does not require
Standard tier does not require you to buy equipment, install physical security measures, produce a documented risk assessment, submit anything to the SIA beyond notification, or run training or drills. None of those are requirements of the Act.
No documentation duty
Standard tier premises must have public protection procedures. They are not required to document them for the regulator, and nothing is submitted to the SIA beyond the initial notification.
The documentation duty and the security document belong to enhanced tier.
No training or drills requirement
Neither staff training nor drills are required by the Act, at either tier. Both are sensible, and both help you show your procedures are real rather than theoretical, but neither is a legal obligation.
This matters because a great deal of what is sold as Martyn's Law compliance is training. Read carefully whether what you are being offered meets a duty or exceeds one.
No equipment or physical measures
Standard tier requires no physical security measures at all. The Home Office models standard tier compliance as a low cost precisely because the duties are procedural.
Public protection measures — monitoring, physical safety, security of information — are an enhanced tier duty under section 6.
Why you may hear otherwise
Overstating the duties is common, usually from someone selling a service that meets the overstatement. It is worth checking any claim about what you must do against the Act itself.
