A health and safety audit is one of the most effective ways to understand how well your organisation is managing workplace safety. It gives you the opportunity to review your policies, procedures and day-to-day practices, identify gaps, and ensure you are meeting your legal responsibilities.
When it comes to planning an audit, many businesses face a key question:
Should it be conducted internally or by an external specialist?
Both approaches offer valuable insights, but they serve different purposes. Understanding the strengths of each can help you make the right decision for your business.
A health and safety audit is a structured review of your organisation’s health and safety management systems, including documentation, procedures and working practices.
Its purpose is to evaluate how effectively your current arrangements are working, highlight areas for improvement, and ensure alignment with legal requirements.
Unlike a risk assessment, which focuses on specific hazards, an audit takes a wider view, examining the systems and processes that underpin safety across your organisation.
An internal health and safety audit is carried out by someone within your organisation. This could be a health and safety manager, a member of your leadership team, or another employee with relevant responsibilities.
Internal audits are typically used to review existing practices, monitor ongoing performance, and ensure policies are followed consistently.
Internal auditors are familiar with your operations, making it easier to identify practical and realistic improvements.
You can carry out internal audits regularly, helping you maintain continuous oversight of your health and safety performance.
If you already have in-house expertise, internal audits can be a cost-efficient way to review your systems.
Familiarity with processes can make it easier to overlook issues or accept existing practices without question.
Not all organisations have the specialist knowledge needed to assess complex compliance requirements.
Internal reviewers may find it harder to challenge established ways of working.
An external health and safety audit is carried out by an independent health and safety consultant or specialist provider.
This type of audit provides an objective review of your organisation’s safety systems, workplace environment and documentation, along with practical recommendations for improvement.
External auditors bring a fresh, unbiased view, helping identify risks that may have been missed internally.
Consultants work across a wide range of industries, offering broader knowledge of best practice and regulatory requirements.
You receive a detailed report with practical steps to strengthen your health and safety approach.
An independent assessment can reassure leadership teams that systems have been reviewed thoroughly and professionally.
External audits require investment, although many businesses view this as a proactive step towards managing risk.
External auditors may need time to fully understand your processes before completing their assessment.
| Factor | Internal Audit | External Audit |
| Objectivity | Limited by familiarity | Independent and unbiased |
| Expertise | Depends on internal skillset | Broad industry experience |
| Cost | Lower direct cost | Higher initial investment |
| Frequency | Can be carried out regularly | Typically conducted periodically |
| Depth | May be more focused or selective | Usually more comprehensive |
The right choice depends on your organisation’s size, resources and level of in-house expertise.
In practice, many organisations benefit from using both approaches together.
Regular internal audits help maintain oversight throughout the year, while periodic external audits provide an objective review and highlight opportunities for improvement that may otherwise be missed.
Under the Health and Safety at Work etc. Act 1974, employers have a legal duty to protect the health, safety and welfare of their employees. Regular audits help you assess how effectively you are meeting these responsibilities.
Beyond compliance, audits also help you to:
A well-planned audit isn’t just a box-ticking exercise; it’s an opportunity to strengthen how your organisation protects its people.
Choosing between an internal and external health and safety audit is not about selecting one over the other. Both play an important role in building a strong safety culture.
Internal audits provide regular visibility and ongoing performance monitoring. External audits bring independent expertise, objective insight and practical recommendations.
By combining both approaches, you can create a balanced strategy that supports compliance, protects your workforce and drives continuous improvement.
If you want a clearer picture of how your organisation is performing, expert support can make all the difference.

A health and safety audit is a structured review of your organisation’s systems, policies and practices. It helps identify gaps, assess compliance and highlight areas for improvement.
A risk assessment focuses on specific hazards, while an audit evaluates your overall health and safety management systems and how effectively they are working.
There is no fixed legal frequency. However, regular audits are recommended to review performance, maintain compliance and support continuous improvement.
An external auditor will typically review your documentation, assess your workplace and evaluate how risks are being managed. You will then receive recommendations to improve safety and compliance.
Yes. Businesses of all sizes can benefit from understanding their current performance, identifying risks and implementing practical improvements.
