Protecting employee health is a growing priority for UK employers. Importantly, health surveillance plays a central role in reducing sickness absence, improving retention, and meeting legal duties under UK health and safety law. In practice, many organisations are also required to carry out statutory medical assessments, depending on workplace risks. Understanding the difference is essential for compliance and workforce wellbeing.
This guide explains how health surveillance and statutory medicals work, why they matter, and what UK employers need to know to stay compliant.
What Is Health Surveillance?
Health surveillance is a systematic, ongoing process used to identify early signs of work-related ill health in employees exposed to specific occupational risks. According to the Health and Safety Executive, it involves regular checks where there is a clear link between workplace exposure and a known health condition.
In simple terms, it helps employers spot problems early, before symptoms become serious or irreversible. As a result, timely interventions can be introduced to protect both employees and business operations.
Health surveillance is required when:
-
Employees are exposed to hazards known to cause ill health
-
There is a reliable way to detect early signs of harm
-
The risk assessment shows monitoring is necessary
Examples include exposure to noise, vibration, hazardous substances, respiratory irritants, or repetitive tasks.

What Are Statutory Medicals?
Statutory medicals are legally required medical examinations set out under specific UK health and safety regulations. Unlike routine surveillance, these assessments must be carried out at defined intervals and, in many cases, by HSE-appointed or HSE-approved doctors.
Their purpose is to confirm that an employee is medically fit to carry out work that presents higher-risk exposures. Importantly, statutory medicals focus on legal compliance, not optional best practice.
Although statutory medicals and health surveillance are closely linked, they are not interchangeable. In practice, statutory medicals often form one part of a wider workplace monitoring programme.
Key Differences Between Health Surveillance and Statutory Medicals
Health surveillance is a broad, preventative approach designed to detect early signs of work-related ill health. Statutory medicals, however, are mandatory medical assessments required by law for specific roles or exposures.
| Aspect | Health Surveillance | Statutory Medicals |
|---|---|---|
| Legal status | Required where risk assessment identifies a need | Explicit legal requirement under regulations |
| Frequency | Based on risk and exposure | Defined by legislation |
| Purpose | Early detection and prevention | Confirm medical fitness for high-risk work |
| Clinician | Occupational health professional | HSE-appointed / approved doctor |
Understanding this distinction helps employers apply the correct level of monitoring and avoid compliance gaps.
Who Requires a Statutory Medical?
Employees working in certain high-risk environments must legally undergo statutory medical assessments. These requirements sit within specific UK regulations, including:
Further guidance is available directly from the HSE statutory medical surveillance guidance.
Failure to meet these requirements can lead to enforcement action, operational delays, and increased risk to employee health.
What About Safety-Critical Medicals?
In addition to statutory requirements, many employers use safety-critical medicals for roles where sudden illness or reduced capacity could create serious risk. While these are not legally mandated, they are widely recognised as best practice.
Safety-critical assessments support safer decision-making in industries such as construction, transport, manufacturing, aviation, and energy. They also demonstrate a proactive approach to risk management.
Why Health Surveillance and Statutory Medicals Matter
The primary goal of both approaches is early identification of potential harm. When health changes are detected promptly, employers can adjust work tasks, introduce controls, or provide support before conditions worsen.
As a result, organisations benefit from:
-
Reduced sickness absence and long-term ill health
-
Stronger legal compliance and audit readiness
-
Improved employee confidence and engagement
-
Better quality risk management decisions
Importantly, health data trends can also highlight where workplace controls may need improvement.
For a structured approach, many employers adopt:
-
Pre-employment health screening
-
Ongoing monitoring linked to risk exposure
-
Exit health assessments to identify long-term trends

Legal Responsibilities for UK Employers
Under the Health and Safety at Work etc. Act 1974, employers have a duty to protect employee health where risks arise from work activities. This includes implementing appropriate monitoring where required.
In addition, COSHH and other sector-specific regulations make health surveillance and statutory medicals a legal obligation, not an optional wellbeing initiative.
Up-to-date regulatory information is available via GOV.UK workplace health and safety guidance.
