Occupational Health Assessment in Ireland: What to Expect (2026 Guide)

Last reviewed: July 2026

If your employer has referred you for an occupational health assessment, you may be wondering what it involves and whether it’s something to worry about.

The good news is that an occupational health assessment isn’t an exam you can pass or fail. It’s an independent medical assessment that helps determine how your health may affect your ability to work safely and whether any workplace adjustments could support you.

In Ireland, employers commonly request occupational health assessments when an employee is returning after a long period of sick leave, recovering from an injury, managing a long-term health condition, or when there are concerns about their fitness for work.

This guide explains everything you need to know about occupational health assessments in Ireland, including when employers can request one, what happens during the appointment, your rights, what information is shared with your employer, and how the assessment can support your return to work.

Occupational health assessment at a glance

What is an occupational health assessment?

An occupational health assessment is an independent medical assessment that looks at how a person’s physical or mental health affects their ability to perform their job safely and effectively.

Unlike your GP, whose primary role is to diagnose and treat medical conditions, an occupational health professional focuses on the relationship between your health and your work. Because they have specialist knowledge of the work environment that your own doctor may not have, their opinions may sometimes differ from your GP’s.

The purpose of the assessment is not to decide whether you’re genuinely ill or to judge your performance. Instead, it provides practical advice about your fitness for work and identifies any support or workplace adjustments that may help you continue working safely.

Depending on your circumstances, an occupational health assessment may help answer questions such as:

• Are you currently fit to carry out your normal duties?
• Would temporary workplace adjustments help?
• Is a phased return to work appropriate?
• Are there tasks you should avoid while recovering?
• Could your work be contributing to your health condition?
• Are there measures that could help prevent further illness or injury?

The recommendations made after the assessment help employers make informed decisions while supporting employee health and wellbeing.

What does occupational health do?

Occupational health is a specialist area of healthcare that aims to protect and improve employees’ health in the workplace. Rather than treating illnesses, occupational health professionals assess how work affects health, and how health affects work.

Their role may include:

• Assessing fitness for work
• Advising employers on workplace adjustments
• Supporting employees returning after sickness absence
• Helping prevent work-related illnesses and injuries
• Monitoring employees exposed to workplace hazards
• Promoting healthier working environments
• Supporting employees with long-term health conditions or disabilities

Ultimately, occupational health aims to help people stay healthy, productive, and safe at work.

Why might an employer request an occupational health assessment?

Being referred for occupational health doesn’t necessarily mean your employer doubts your illness or believes you’re unable to do your job. In many cases, referrals are made because employers have a legal duty to protect the health and safety of everyone in the workplace and want expert advice on how best to support an employee.

Returning after long-term sick leave

One of the most common reasons for referral is returning after several weeks or months away from work due to illness or injury. An occupational health assessment can help determine whether you’re ready to return, whether temporary adjustments are needed, whether a phased return would be beneficial, and how your employer can best support your recovery. You can read our practical guide on returning to work after long-term sick leave.

Frequent short-term absences

If you’ve had several periods of sickness absence over a relatively short period, your employer may request an assessment to better understand whether an underlying health issue is affecting your attendance. The purpose is to identify appropriate support rather than to question the legitimacy of your absences.

Recovering from surgery or injury

Following surgery, fractures, or significant injuries, occupational health can advise whether you’re able to resume your usual duties safely. Recommendations may include temporary lifting restrictions, reduced hours, or modified responsibilities while you continue recovering.

Mental health concerns

Occupational health assessments are increasingly used to support employees experiencing:

• Anxiety
• Depression
• Workplace stress
• Burnout
• Adjustment disorders, or other mental health conditions

The assessment focuses on how symptoms affect work and identifies practical measures that may support recovery and reduce the risk of further absence.

Managing long-term health conditions

Employees living with ongoing medical conditions such as arthritis, diabetes, multiple sclerosis, chronic pain, epilepsy, asthma, or heart disease may benefit from occupational health advice. Recommendations often focus on practical workplace adjustments that allow employees to continue working safely wherever possible.

Workplace accidents or injuries

If you’ve been injured at work, your employer may request an occupational health assessment before you return to ensure it’s safe for you to resume your duties and to reduce the risk of re-injury.

Safety-critical roles

Certain occupations involve higher physical or safety demands. For example, employees working in construction, healthcare, manufacturing, transport, emergency services, or roles involving heavy machinery may require occupational health assessments to ensure they can carry out essential duties safely.

Exposure to workplace hazards

Some employees are exposed to hazards such as:

• Hazardous chemicals
• Excessive noise
• Vibration
• Dust
• Biological agents, or respiratory risks

Occupational health assessments and ongoing health surveillance help identify any work-related health concerns at an early stage and ensure appropriate control measures remain effective. In certain higher-risk sectors, including those involving night work, chemical or biological agents, noise, or radiation, health surveillance is a mandatory legal requirement under the Safety, Health and Welfare at Work Act 2005 and associated regulations.

Who carries out an occupational health assessment?

Occupational health assessments are carried out by healthcare professionals with specialist training in workplace health. Depending on the nature of the referral, you may see:

• An occupational health physician
• An occupational health nurse
• A physiotherapist working within occupational health
• Another qualified occupational health practitioner

These professionals work independently and are expected to provide objective medical advice based on the information available. Disclosure of medical information is governed by the guidelines of the Faculty of Occupational Medicine, which set professional standards for what may be shared and how.

Benefits of occupational health assessments

Occupational health assessments support both employees and employers by promoting safer workplaces, improving wellbeing, and helping people return to or remain in work safely.

Benefits for employees

An occupational health assessment can:

• Support a safe return to work after illness or injury
• Recommend workplace adjustments where needed
• Help prevent existing health conditions from worsening
• Improve communication with employers
• Promote physical and mental wellbeing

It also gives employees the opportunity to discuss work-related health concerns with an independent occupational health professional.

Benefits for employers

Occupational health assessments can help employers:

• Reduce sickness absence
• Support employee wellbeing and retention
• Meet workplace health and safety obligations
• Make informed decisions about fitness for work
• Plan safe and effective return-to-work arrangements

Early occupational health support can help address issues before they lead to prolonged absence or more serious workplace challenges.

What happens during an occupational health assessment?

Many people worry they’ll undergo extensive medical tests, but most occupational health assessments are discussion-based. The appointment is designed to understand how your health affects your ability to work and whether any support or adjustments may be needed. Appointments usually last 30 to 60 minutes, depending on the reason for the referral.

During the assessment, the occupational health professional may ask about:

• Your current medical condition and symptoms
• Any treatment or medication you’re receiving
• Your recovery progress
• Your normal job duties
• Tasks you find difficult because of your health
• How your condition affects your work and daily activities
• Your expected recovery timeline

Will occupational health contact my GP?

Sometimes. If additional medical information is needed, the occupational health professional may ask for your permission to contact your GP or hospital consultant. Your written consent is generally required before medical information is requested or shared. Without your consent, your healthcare provider cannot usually release confidential medical records.

Is an occupational health assessment confidential?

Yes. Occupational health professionals are bound by medical confidentiality and Irish data protection laws. Your employer does not receive unrestricted access to your medical records. Instead, they usually receive a report outlining how your health affects your ability to work and any recommended workplace adjustments.

Detailed medical information or diagnoses are generally only shared with your consent and where relevant.

Can you refuse an occupational health assessment?

In most cases, employers can ask you to attend an occupational health assessment, particularly when it’s needed to manage sickness absence or workplace health and safety. While the assessment generally relies on your consent, refusing to attend may mean your employer has to make decisions based on the medical information already available, without the benefit of specialist advice.

If you’re unsure why you’ve been referred, ask your employer to explain the purpose of the referral before your appointment.

Can occupational health sign you off work?

No. Occupational health professionals generally do not issue sick certificates. Their role is to assess how your health affects your work and recommend appropriate workplace adjustments or return-to-work plans. If you need a medical certificate for sick leave, this is normally provided by your GP or treating doctor. Read our detailed guide on how to get a sick cert online in Ireland.

Can occupational health override your GP?

No. Your GP and occupational health professional have different roles. Your GP diagnoses and treats your medical condition, while occupational health advises your employer on your fitness for work and any adjustments that may help you return safely. Although their opinions may differ, occupational health does not override your GP’s clinical judgement.

Preparing for your occupational health assessment

A little preparation can help you get the most from your appointment. Before attending:

• Review your current symptoms and recovery progress
• Think about which work tasks you can and cannot manage comfortably
• Bring details of any medications you’re taking
• Have information about recent treatment or hospital appointments if relevant
• Consider any workplace adjustments you believe would help

Remember, the assessment is there to support you, not to catch you out.

Occupational health assessments and Irish employment law

Occupational health assessments form part of an employer’s responsibility to provide a safe workplace. In Ireland, this is supported by legislation including:

• Safety, Health and Welfare at Work Act 2005, which requires employers to protect employees’ health and safety.
• Employment Equality Acts 1998-2015, which may require employers to consider reasonable accommodations such as modified duties, adjusted working hours, specialist equipment, or remote working for employees with disabilities where appropriate.
• General Data Protection Regulation (GDPR) and the Data Protection Act 2018, which govern how personal health information is collected, stored, and shared.

These assessments help employers make informed decisions while respecting employees’ privacy and legal rights.

What happens after an occupational health assessment?

After your appointment, the occupational health professional will prepare a report for your employer. The report provides independent advice about your fitness for work and any support that may help you return safely.

Possible recommendations include:

• Returning to your normal duties
• Returning with temporary workplace adjustments
• A phased return to work
• Temporary work restrictions
• Further occupational health review if needed

Once your employer receives the report, they will usually discuss the recommendations with you. Depending on the outcome, you may return to your usual duties, start a phased return, or agree on temporary workplace adjustments. In some cases, a follow-up occupational health review may be arranged.

While employers should carefully consider these recommendations, the final decision about your employment or work arrangements rests with your employer.

What is a phased return to work?

A phased return to work allows you to gradually resume your duties after a period of sickness absence rather than returning to full-time work immediately. This may involve working fewer hours initially, taking on lighter duties, or gradually increasing your workload over several weeks. A phased return is commonly recommended after surgery, serious illness, injury, or mental health-related absence. Here is our full guide to phased return to work in Ireland.

Your rights during an occupational health assessment

As an employee in Ireland, you have the right to:

• Know why you’ve been referred
• Have your personal health information handled confidentially
• Give consent before your GP or specialist is contacted
• Be treated fairly and respectfully throughout the process
• Receive an independent and objective assessment

Employers also have a responsibility to consider reasonable workplace adjustments where appropriate while maintaining a safe working environment.

Final thoughts

An occupational health assessment is designed to support both employees and employers by ensuring work can be carried out safely and sustainably. Rather than assessing whether you’re “fit” or “unfit” in isolation, it focuses on how your health affects your role and what support may help you remain in or return to work.

Understanding the process, your rights, and what to expect can help you approach the assessment with confidence. By working collaboratively with your employer and the occupational health professional, it’s often possible to identify practical solutions that support both your recovery and your long-term wellbeing at work.
