Entity scoping is critical here

**The verified ISO 9001 certificate covers G4S Risk Management Ltd (the risk-consulting arm), not G4S Secure Solutions (UK) Limited (the guarding business).** Do not publish it against the guarding entity.

Other G4S UK entities hold their own NSI accreditations and are legally distinct: G4S Cash Solutions (UK) Ltd (Cash Services Gold), G4S Fire & Security Systems (UK), G4S Aviation Services (UK) Limited (Guarding Gold, Gatwick).

ISO 14001, 45001, 27001, 50001 and Cyber Essentials: **no public evidence found**. The G4S UK memberships page contains a single generic sentence and lists no accreditations at all — verified by rendering the page, so it is genuinely empty.

**No security contact or disclosure programme found.** [email protected] is a privacy address and should not be treated as a security channel. The UK privacy notice has not been updated since 22 May 2018. Key entity: G4S Secure Solutions (UK) Limited, company 01046019.
