What is a SEQOHS Medical?

A SEQOHS Medical—short for Safe Effective Quality Occupational Health Service medical—is a professional health assessment conducted by a SEQOHS-accredited occupational health provider. This medical is designed specifically for workers in safety-critical roles, where health issues could pose a risk to the individual, their colleagues, or the public. Common industries requiring a SEQOHS Safety Critical Medical include construction, highways, rail, transport, logistics, utilities, manufacturing, engineering, and warehousing.

The purpose of a SEQOHS medical assessment is to determine whether a worker is fit to work in hazardous or high-pressure environments. This type of safety critical medical helps ensure that the person can safely perform tasks such as working at height, operating heavy machinery, driving large vehicles, working in confined spaces, or being responsible for public safety. The assessment covers key health indicators such as vision, hearing, blood pressure, mobility, respiratory health, and mental wellbeing—each tailored to the specific demands of the role.

The SEQOHS framework is governed by the Faculty of Occupational Medicine (FOM) and sets out the clinical standards that occupational health providers must meet. Employers across the UK, particularly in safety-sensitive sectors, are legally required to follow these guidelines to comply with Health and Safety Executive (HSE) regulations. That’s why many companies mandate a SEQOHS Safety Critical Medical before a worker sets foot on-site or begins a new safety-critical role.

For a detailed breakdown of what’s included in a typical SEQOHS Safety Critical Medical, how long the certificate lasts, and why it’s crucial to your career, check out our comprehensive guide:

Why Do You Need a SEQOHS Safety Critical Medical?

If you’re working in a high-risk environment where your health can directly affect your own safety—or the safety of your team and the general public—a SEQOHS Safety Critical Medical isn’t just a recommendation; it’s a legal and operational necessity. Whether you’re on-site in a construction zone, maintaining railway infrastructure, operating heavy machinery, or performing tasks in hazardous environments, a safety critical medical assessment ensures you’re fit to work without putting yourself or others at risk.

The SEQOHS medical process, overseen by a SEQOHS-accredited occupational health provider, is designed to uphold the highest standards of workplace health and safety. It supports employers in meeting Health and Safety Executive (HSE) obligations while safeguarding workers in physically and mentally demanding roles. In many industries, failing to complete or pass a SEQOHS Fit to Work Medical can result in denied site access, missed job opportunities, or non-compliance with regulatory frameworks.

Industries that often require this assessment include

By attending a SEQOHS-accredited safety critical medical, you demonstrate that you are physically and mentally fit for safety-critical duties, boosting your employability, maintaining compliance with industry standards, and gaining peace of mind. Employers rely on this medical evidence to protect their workforce and reduce liability.

If you’re unsure whether your job requires a SEQOHS Fit to Work Medical, it’s always best to check with your employer or occupational health provider. However, if you’re involved in any high-risk occupation in regions like Birmingham, Norwich, Swindon, or the broader Midlands, chances are, a SEQOHS medical is not just required—it’s crucial for site access and continued employment.

What Does a SEQOHS Medical Include?

Before you step onto a safety-critical site, you need to prove you’re medically fit to do the job—and that’s exactly what a SEQOHS Safety Critical Medical is designed to determine. This Fit to Work Medical, delivered under the SEQOHS (Safe Effective Quality Occupational Health Service) standard, assesses whether your physical and mental health aligns with the safety demands of your role. Whether you’re preparing for a construction project, a logistics contract, or a rail assignment, understanding what’s covered in a SEQOHS Medical will help you feel prepared and compliant.

Every SEQOHS-accredited safety critical medical follows strict clinical protocols tailored to the job role and its associated risks. The tests listed below are core components of a safety critical medical assessment, especially for professionals working across the Midlands, Birmingham, Norwich, Swindon, and other high-risk operational zones.

The specifics may vary slightly depending on your role, but typically, a Safety Critical Medical will assess:

If you are required to work at heights or in confined spaces, additional assessments may be included.

These health checks are not just tick-box exercises—they are fundamental to confirming your fitness for safety-critical tasks in demanding industries like construction, highways, and utilities. If you’re working at heights, underground, or in fast-paced environments, additional testing may be added based on your risk profile and the requirements of the job.

Completing a thorough SEQOHS Safety Critical Medical not only keeps you compliant with HSE and employer standards but also demonstrates your commitment to safety and professionalism. Whether you’re based in the Midlands, travelling for work in Birmingham, operating machinery in Norwich, or preparing for a new contract in Swindon, attending a full SEQOHS-compliant Fit to Work Medical ensures you’re ready for duty—confident, cleared, and capable.

When Should You Book Your SEQOHS Fit to Work Medical?

Booking your SEQOHS Fit to Work Medical at the right time is essential for ensuring you’re cleared to work safely and legally in any safety-critical role. Most employers will require that your SEQOHS Safety Critical Medical is completed before your first day on site, especially in high-risk sectors like construction, rail, utilities, and transport. Without valid certification from a SEQOHS-accredited occupational health provider, you may be denied access to safety-critical environments.

For most roles, you’ll need to complete the SEQOHS medical before your first day on site. Referrals may also be made during employment if:

  • Your employer has health concerns.

  • You return from a long-term illness.

  • You are taking on new responsibilities.

  • Your certification is due for renewal (usually every 1-3 years).

Many major employers and contractors across the Midlands, Birmingham, Norwich, and Swindon strictly enforce up-to-date Fit to Work Medicals as part of their health and safety compliance policies. Delaying your SEQOHS medical assessment can lead to lost workdays, suspended site access, and potential breaches of legal obligations under HSE regulations.

To stay compliant and avoid disruptions to your schedule or employment, it’s recommended to book your SEQOHS Safety Critical Medical as early as possible—especially if you’re preparing for a new contract, onboarding with a new employer, or renewing your existing certification.

At D4 Medicals, we provide fast-track, flexible appointments for SEQOHS-accredited medicals across the Midlands, including key locations like Birmingham, Norwich, and Swindon. All assessments are carried out by trained occupational health professionals following the official SEQOHS standards, ensuring you meet the requirements for site entry and workplace safety.

How to Prepare for Your SEQOHS Safety Critical Medical?

If you’ve been booked in for a SEQOHS Safety Critical Medical, preparation is key to making the process smooth, stress-free, and compliant with employer and legal requirements. Whether you’re attending a Fit to Work Medical for a construction role, rail project, or utilities-based job, your performance on the day is greatly influenced by how you prepare the night before and the morning of your appointment.

A SEQOHS-accredited Safety Critical Medical is not something to be nervous about—it’s designed to ensure you’re medically fit to carry out safety-sensitive work. Below are some essential steps to help you prepare properly and give you the best chance of receiving your Fit to Work certificate with minimal delays.

Get a Good Night’s Sleep

Rest is crucial before any occupational health medical, especially one that includes vital checks like blood pressure and coordination. Fatigue can lead to elevated blood pressure, poor vision results, slower reflexes, and reduced concentration—all of which may affect the outcome of your SEQOHS Medical. Aim for a full 7–9 hours of quality sleep the night before your safety critical medical assessment.

Being well-rested ensures accurate readings during key tests such as spirometry (lung function), audiometry (hearing), and vision testing, all core components of a SEQOHS Fit to Work Medical.

Avoid Caffeine, Alcohol, and Energy Drinks

Stimulants and depressants can have a temporary impact on your body’s vital signs. Drinks like coffee, tea, fizzy energy drinks, or alcohol may alter your blood pressure, heart rate, and mental responsiveness, leading to potentially misleading results during your safety critical medical.

To avoid unnecessary delays or re-tests, steer clear of these substances for at least 12 hours prior to your SEQOHS Safety Critical Medical. This simple step will help ensure your Fit to Work assessment reflects your true health status.

Bring the Required Documentation

Arriving without the correct paperwork can delay or cancel your SEQOHS Medical appointment. Make sure you bring the following:

  • Valid Photo ID (passport or driving licence)

  • Any glasses or hearing aids you use regularly

  • A list of current medications, including dosage

  • Previous medical history or existing occupational health records (if applicable)

If you’ve had any prior Safety Critical Medicals, hearing or lung function tests, or assessments related to confined space or working at heights, bring documentation with you. Some Fit to Work Medicals require role-specific certificates or past occupational health assessments, especially in industries like construction or logistics.

Dress Comfortably

Your SEQOHS Medical may include a mobility and musculoskeletal assessment, where you’ll be asked to perform basic movements like squatting, bending, or lifting. Wear loose, comfortable clothing that allows for easy movement, and avoid tight or restrictive garments.

Flat, supportive shoes are recommended—avoid sandals, steel-toe boots, or dress shoes. Comfortable attire ensures the clinician can evaluate your range of motion and physical capability accurately, which is essential for roles involving manual handling or safety equipment.

Be Honest in Your Answers

A SEQOHS-accredited Safety Critical Medical is not an exam you pass or fail—it’s a Fit to Work assessment that evaluates whether you’re physically and mentally safe to perform your duties. If you try to hide an ongoing condition, history of illness, or medication use, you may inadvertently endanger yourself or your coworkers.

Occupational health professionals are not there to judge but to assess risk and advise accordingly. Transparency ensures the safest outcome and allows for workplace adjustments if needed. This is particularly important in industries governed by strict HSE regulations and employer duty of care policies.

Take Medications as Usual

Unless instructed otherwise, continue taking your prescribed medication on the day of your SEQOHS Safety Critical Medical. If you’re unsure whether any of your medications could affect your test results—such as heart medication, inhalers, antidepressants, or insulin—mention them during your consultation.

Your Fit to Work Medical includes a review of your current medications as part of the occupational health screening. Being upfront about all prescriptions and over-the-counter drugs helps the assessor make an informed decision regarding your fitness for safety-critical work.

Additional Preparation Tips

  • Arrive early – Give yourself time to check in, relax, and avoid rushing

  • Stay calm – Nervousness can affect blood pressure and heart rate

  • Avoid smoking before your test – Especially important for the spirometry test

  • Ask questions – If you don’t understand any part of the process, ask your SEQOHS occupational health provider for clarification

Proper preparation for your SEQOHS Safety Critical Medical ensures a smoother experience and helps you meet the physical and mental standards expected in safety-critical industries. These exams are a vital part of maintaining workplace safety and ensuring legal compliance through a Fit to Work Medical delivered by a SEQOHS-accredited occupational health service.

By following the steps above, you can walk into your SEQOHS Medical assessment confident and ready—knowing that you’ve done everything possible to ensure an accurate, fair outcome. Whether it’s your first time or a routine renewal, preparation is your best tool for success.

What Happens If You Don’t Meet the Criteria?

Not everyone who attends a SEQOHS Safety Critical Medical will meet the required standards on their first attempt—and that’s okay. Failing a Safety Critical Medical assessment does not automatically mean job loss or dismissal. These health checks are designed to support workplace safety and individual well-being, not to penalise employees. If you don’t pass your initial Fit to Work assessment, it’s important to understand that several occupational health support pathways are available. A SEQOHS-accredited occupational health provider will assess your results in detail and offer one or more of the following options to help you meet the safety standards required for your role:

  • You may be advised to avoid certain tasks or environments until your condition improves or is reviewed again.

  • This could include modified duties, altered schedules, or new equipment that better suits your needs.

  • If a potential medical condition is identified, your occupational health provider might suggest further investigation or treatment through your personal healthcare provider.

  • In many cases, you’ll be allowed to return for a retest after receiving treatment or making health improvements.

For example, if your vision test reveals eyesight that is just below the required standard, but can be corrected with prescription glasses, the provider will usually allow you to return for a second assessment wearing the appropriate corrective lenses. Similarly, if your spirometry test (lung function) or audiometry (hearing) shows a temporary deficiency—due to a cold, infection, or temporary hearing loss—you may be re-tested at a later date.

These solutions are all part of the holistic approach that defines a SEQOHS Safety Critical Medical. The goal is to determine whether you’re currently fit for work—and if not, what can be done to get you back to full fitness while still safeguarding the safety of you and those around you.

How Long Does a SEQOHS Medical Take?

The length of time for a SEQOHS Safety Critical Medical can vary depending on several factors, but in most cases, a Fit to Work Medical typically lasts between 30 to 60 minutes. However, the exact duration of your SEQOHS Medical assessment will depend on the complexity of the job role you’re applying for, any specific tests required, and whether your Fit to Work Medical involves additional specialist assessments.

Factors That Influence the Duration of a SEQOHS Medical:

  • The time required for a SEQOHS Safety Critical Medical can differ based on the role’s health and safety demands. Jobs that are classified as safety critical—such as those in construction, transportation, rail, or heavy machinery—may require more comprehensive testing. This is to ensure you’re fully fit to work in environments where even minor health risks could have significant consequences for both you and others.

    For example, construction workers or those working in high-risk environments like working at heights or confined spaces will likely need additional assessments beyond standard health checks. These could include tests for mobility, musculoskeletal health, or cardiovascular function, which may extend the time needed for a full SEQOHS medical assessment.

  • If your role involves activities such as working at heights, heavy lifting, or operating heavy machinery, you may need additional tests that can increase the duration of the assessment. A few common specialist evaluations include:

    • Vision Tests: For roles that require clear sight for safety, you will undergo detailed vision checks, including colour blindness screening.

    • Lung Function Tests (Spirometry): Especially for workers in dusty or fume-filled environments, a spirometry test is necessary to evaluate how well your lungs function under stress.

    • Hearing Tests (Audiometry): A critical test for roles in noisy environments, such as construction sites or factories, where hearing loss could severely impact safety.

    • Musculoskeletal Assessments: If your role involves frequent lifting, bending, or heavy manual work, a physical assessment may be performed to evaluate your strength, flexibility, and ability to perform these tasks safely.

  • The length of your SEQOHS Medical can also be influenced by the information you provide regarding your medical history. If you’ve had previous medical issues or are on long-term medication, your SEQOHS-accredited occupational health provider may need to spend extra time reviewing this information. The provider may need to ask follow-up questions to assess whether your medical conditions could affect your ability to work safely in a high-risk role.

  • Older workers or those with pre-existing conditions may require additional checks, especially for cardiovascular health or mental well-being. Mental health screenings, for example, may be included for roles that demand significant mental and physical focus. For such individuals, the SEQOHS medical may take longer, as extra consultations and assessments will be required.

While a SEQOHS Safety Critical Medical typically takes between 30 to 60 minutes, the time required can vary depending on the complexity of your role and any additional tests you need. Specialist assessments, your medical history, and whether you’re required to meet additional fit for work criteria will all influence the total duration of your appointment.

By understanding the factors that affect the length of a SEQOHS Medical, you can better prepare for the process, ensuring everything runs smoothly. The goal of the SEQOHS Safety Critical Medical is to confirm that you’re fully capable of performing your job safely and without risk to your health or the safety of others around you.
