are practitioners not regulated by law, to give the public confidence in their services?

This question appears to conflate professional statutory regulation with the academic regulation of qualifications. The Level 7 Diploma in Strategic Management and Leadership is an academic credential, not a license to practice a protected profession like medicine or law. Consequently, it does not confer statutory authority. Instead, it provides evidence of master’s-level strategic capability. Public confidence in management services stems from organisational governance and proven business outcomes, not individual statutory registration. The diploma is regulated by Ofqual to ensure academic rigour, not to police professional conduct. Practitioners rely on corporate reputation and board-level accountability. This distinction is critical for managers understanding the value of the qualification. It enhances strategic direction and organisational capability without implying legal protection of title.
