Blog Post: Who is accountable and why

Understanding who owns OSH decisions and outcomes

Principle: Accountability

Accountability and responsibility are closely related concepts in professional and personal contexts, but they have important differences. Understanding these distinctions is essential in occupational safety and health (OSH), and in some cases, can be legally significant.

So how should the principle of accountability be explained?

Accountability vs responsibility

Accountability is about ownership and being answerable for outcomes. It means being held to account for whether actions were taken or whether required levels of performance were achieved. Accountability cannot be delegated – it remains with the individual who holds it.

Responsibility, however, relates to the specific tasks or duties assigned to someone to enable an accountable person to meet their obligations. Responsibilities can be delegated.

An OSH professional may be responsible for preparing monthly health and safety reports, but the accountable director remains answerable for the accuracy, completeness and use of those reports.

In other words:

  • Responsibility = execution
  • Accountability = ownership of consequences

Accountability in governance

In OSH governance, many organisations include decision‑making delegations within the arrangements section of their health and safety policies. These should be reviewed regularly to ensure they align with current structures and roles.

Responsibilities may also be reflected in:

  • job descriptions 
  • procedural documents 
  • performance records

Regular review ensures clarity and prevents misunderstandings about who is accountable for what.

Delegation and UK law

Delegation carries additional considerations under UK law.

Vicarious liability and the “master–servant” principle

Under this principle, an employer (the “master”) can be held responsible for wrongful acts committed by an employee (the “servant”) while they are carrying out their duties.

What about contractors?

Traditionally, UK courts distinguish between:

  • a contract of service (employment)
  • a contract for services (self‑employment)

Employers generally have liability only for employees, not contractors. The key legal test is the right of control – whether the employer directs how, when and where work is carried out.

Modern judgements may also consider:

  • mutual obligations
  • requirement for personal service
  • degree of integration into the organisation

A customer was injured by security staff employed by an external contractor. Although the security team were not employees, the High Court found Wetherspoon had:

  • dictated their uniforms 
  • fully integrated them into daily operations 

The court judged that the security team were effectively managed like employees. Wetherspoon was therefore vicariously liable for their actions.

The “controlling mind” doctrine

Another related UK legal principle is the controlling mind. This applies to individuals whose decisions and intent are so central to the organisation that their actions legally represent the organisation itself.

In Tesco v Natrass (1971), the House of Lords clarified that a controlling mind must be someone with genuine authority and not accountable to others for how duties are performed.

Why clarity matters

Because definitions can be confused or used inconsistently, organisations must take care when describing responsibility and accountability in their documentation. Clear, accurate use of these terms reduces legal and organisational risk.

OSH professionals have an important role in ensuring that:

  • accountability remains visible and understood
  • responsibilities are appropriately delegated
  • documentation aligns with legal principles

This supports transparency, good governance and safe decision‑making.
