Understanding SEQOHS in Occupational Health

In high-risk industries such as construction, infrastructure, rail, civil engineering, logistics, and energy, ensuring employees are medically fit for work is critical. For individuals in safety-critical roles, fitness assessments are not simply a regulatory requirement—they are a fundamental part of preventing incidents, protecting lives, and maintaining operational continuity. When impaired health or reduced alertness could result in serious harm, Safety Critical Medicals play a vital role in workplace risk management.

This is where SEQOHS accreditation becomes essential. Developed by the Faculty of Occupational Medicine, SEQOHS (Safe Effective Quality Occupational Health Service) is the UK’s recognised quality standard for occupational health providers. It sets clear benchmarks for clinical governance, practitioner competence, data protection, and service delivery.

For employers, choosing a SEQOHS-accredited occupational health provider offers confidence that medical assessments are conducted to consistently high clinical and professional standards. Accreditation demonstrates alignment with Health and Safety Executive (HSE) guidance, the Construction (Design and Management) Regulations 2015, and industry-specific fitness-for-work requirements.

SEQOHS accreditation also supports best practice in areas such as evidence-based decision-making, confidentiality and GDPR-compliant recordkeeping, and the use of appropriately qualified clinicians who understand the risks associated with safety-critical environments. This is particularly important for organisations operating within regulated frameworks or managing complex, high-risk projects.

Ultimately, working with a SEQOHS-accredited provider helps organisations reduce risk, meet legal and contractual obligations, and promote employee wellbeing. It also supports wider business objectives by safeguarding workforce safety, protecting organisational reputation, and ensuring consistent, reliable occupational health support now and into the future.

What Does SEQOHS Mean for Occupational Health?

SEQOHS stands for Safe Effective Quality Occupational Health Service. It is a nationally recognised accreditation developed and maintained by the Faculty of Occupational Medicine (FOM) to ensure consistent, high standards across occupational health services in the UK. SEQOHS accreditation confirms that a provider meets strict requirements for clinical governance, practitioner competence, confidentiality, ethical practice, and service quality.

For employers—particularly those operating in high-risk sectors such as construction, rail, utilities, engineering, and infrastructure—working with a SEQOHS-accredited provider offers reassurance that occupational health services are delivered in line with Health and Safety Executive (HSE) expectations and relevant regulatory frameworks. Accreditation provides independent verification that assessments are robust, compliant, and fit for purpose.

SEQOHS plays a vital role in the delivery of Safety Critical Medicals (SCMs). These assessments determine whether individuals are medically fit to carry out safety-sensitive roles without posing a risk to themselves, colleagues, or the wider public. Depending on the role, Safety Critical Medicals may include hearing tests (audiometry), lung function testing (spirometry), vision screening, musculoskeletal assessments, mental health evaluations, and drug and alcohol testing.

When conducted by a SEQOHS-accredited provider, Safety Critical Medicals are role-specific, evidence-based, and fully aligned with industry standards such as the CDM Regulations 2015, Network Rail medical requirements, and other sector-specific guidelines. This helps organisations meet their legal obligations while reducing the risk of accidents, operational disruption, and potential insurance or liability issues.

By choosing a SEQOHS-accredited occupational health provider, employers demonstrate a proactive commitment to workforce safety, regulatory compliance, and employee wellbeing. It also strengthens organisational credibility, supports contractor and tender requirements, and ensures occupational health services remain compliant with evolving UK regulations now and in the years ahead.

The Importance of SEQOHS in Safety Critical Medical Assessments

In safety-critical sectors such as construction, rail, energy, and utilities, confirming that employees are medically fit to carry out high-risk duties is a fundamental requirement. Where roles involve working at height, operating heavy machinery, or entering confined spaces, even minor health issues can present significant safety risks. Safety Critical Medicals (SCMs) are designed to assess an individual’s fitness for work in these demanding environments.

Choosing a SEQOHS-accredited occupational health provider ensures that Safety Critical Medicals are carried out to recognised national standards. Accreditation confirms that assessments are thorough, role-specific, and fully aligned with regulatory requirements, supporting compliance while placing employee health and safety at the forefront.

By working with a SEQOHS-accredited provider, employers can be confident that medical evaluations are evidence-based, consistently delivered, and designed to reduce risk—helping to protect workers, maintain operational safety, and meet legal obligations.

Why Choose a SEQOHS-Accredited Occupational Health Provider?

Choosing a SEQOHS-accredited occupational health provider ensures that Safety Critical Medicals are delivered to nationally recognised standards, supporting both workforce safety and regulatory compliance.

Assessments are delivered to recognised medical standards
All Safety Critical Medicals follow strict clinical guidelines and evidence-based protocols. This ensures each assessment meets accepted occupational health standards and accurately identifies any medical conditions or risks that could impact an individual’s ability to safely perform safety-sensitive duties—helping to protect both the employee and the wider workforce.

Occupational health professionals are fully qualified and experienced
SEQOHS-accredited providers employ appropriately trained occupational health clinicians, including doctors, nurses, and specialist practitioners. Their expertise ensures assessments are comprehensive, role-specific, and tailored to the unique hazards present across sectors such as construction, rail, energy, and utilities.

Confidentiality, documentation, and follow-up are robustly managed
Strict confidentiality is central to occupational health practice. SEQOHS providers comply with GDPR and data protection requirements, ensuring sensitive medical information is securely stored and accessed only by authorised personnel. Accurate medical records are maintained, and clear follow-up procedures are in place where further assessment or monitoring is required.

Employers remain compliant with UK health and safety legislation
Using a SEQOHS-accredited provider helps employers demonstrate due diligence in meeting their legal obligations under the Health and Safety at Work Act 1974 and the Construction (Design and Management) Regulations 2015 (CDM 2015). Properly documented Safety Critical Medicals reduce the risk of enforcement action, fines, or operational disruption.

Partnering with a SEQOHS-accredited provider ensures Safety Critical Medicals are conducted to the highest clinical and occupational health standards. It supports safer working environments, reduces workplace risk, and helps organisations maintain full regulatory compliance—now and in the years ahead.

Core Components of a SEQOHS Safety Critical Medical

In high-risk industries such as construction, rail, civil engineering, energy, and utilities, comprehensive, role-specific health assessments are essential for maintaining workplace safety and compliance. A SEQOHS-accredited Safety Critical Medical is designed to thoroughly evaluate an employee’s fitness to perform safety-sensitive tasks, helping employers meet occupational health and safety regulations while mitigating risk.

Typical Components of a SEQOHS Safety Critical Medical

  • Vision Assessment – Includes detailed vision testing, colour perception checks, and identification of any visual impairments that could impact safety-sensitive work.
  • Hearing Test (Audiometry) – Evaluates hearing ability, particularly for workers exposed to high noise levels.
  • Respiratory Function (Spirometry) – Measures lung function to ensure employees can safely perform physically demanding tasks.
  • Cardiovascular and Blood Pressure Screening – Detects potential heart and circulation issues that may affect work performance.
  • BMI and General Health Checks – Provides an overview of overall health status.
  • Musculoskeletal Assessment – Identifies any physical limitations or conditions that could affect safe task performance.
  • Mental Health Evaluation – Screens for stress, fatigue, and other psychological factors that could influence safety and well-being.
  • Comprehensive Medical and Occupational History – Reviews past medical conditions, lifestyle factors, and role-specific risks.
  • Drug and Alcohol Testing – Conducted where required to confirm fitness for duty in safety-critical roles.

Each assessment is tailored to the specific risks associated with the employee’s role and project environment, ensuring a complete and accurate evaluation. By delivering customised, evidence-based medical assessments, SEQOHS-accredited providers help employers reduce workplace incidents, maintain compliance with Health and Safety Executive (HSE) standards, and safeguard both employee wellbeing and organisational reputation.

Legal and Industry Standards for Safety Critical Medicals

In high-risk sectors such as construction, rail, civil engineering, energy, and utilities, Safety Critical Medicals (SCMs) are essential for ensuring workplace safety and supporting regulatory compliance. While not explicitly mandated in the same way as DVLA Group 2 HGV medicals, SEQOHS-accredited Safety Critical Medicals have become a widely recognised requirement across the UK due to evolving client contracts, site-specific induction policies, and guidance from the Health and Safety Executive (HSE). Employers and contractors need to understand these obligations to ensure their workforce meets both legal standards and industry best practice, particularly under the Construction (Design and Management) Regulations 2015 (CDM 2015).

Common Drivers for SEQOHS Safety Critical Medicals

SEQOHS-compliant Safety Critical Medicals are increasingly requested or required due to:

  • Client contractual obligations
  • Site-specific induction requirements
  • Recommendations by the Health and Safety Executive (HSE)
  • Compliance with CDM Regulations 2015
  • Insurance and liability requirements
  • Fatigue and fitness-to-work policies
  • Occupational health and safety management systems (e.g., ISO 45001)
  • Trade union or workforce agreements
  • Corporate social responsibility (CSR) and ESG commitments

Major infrastructure projects, including HS2, Crossrail, and other large-scale construction programmes, often require all personnel to complete a SEQOHS-compliant Safety Critical Medical before being granted site access.

By working with a SEQOHS-accredited occupational health provider, organisations can ensure that medical assessments meet these critical standards, supporting:

  • Workforce health and safety
  • Legal and regulatory compliance
  • Insurance coverage requirements
  • Reduced onsite risk
  • Project continuity and operational efficiency

Investing in SEQOHS-accredited Safety Critical Medicals demonstrates a proactive commitment to employee wellbeing, regulatory compliance, and industry best practice in 2025 and beyond.

Why SEQOHS Accreditation Matters for Safety Critical Medicals

Selecting the right provider for Safety Critical Medicals (SCMs) is a critical decision for employers in high-risk sectors such as construction, rail, energy, and civil engineering. Using a non-accredited or uncertified provider can leave your organisation exposed to legal liabilities, regulatory non-compliance, and potential financial penalties.

Partnering with a SEQOHS-accredited occupational health provider ensures that Safety Critical Medicals are conducted to recognised national standards, supporting full health and safety compliance. Accreditation also helps protect insurance coverage, reduces workplace risk, and safeguards your company’s reputation by demonstrating a clear commitment to employee wellbeing and industry best practice.

Identifying Roles That Require a Safety Critical Medical

Not all positions within industries such as construction, rail, civil engineering, and utilities are classified as safety-critical. However, certain roles carry higher operational risks and require stringent medical fitness assessments to ensure both employee health and workplace safety.

Typical positions that often require a Safety Critical Medical include:

  • Construction workers and site engineers – performing tasks at height or in complex environments
  • Plant and machinery operators – including crane and heavy equipment operators
  • LGV drivers and transport personnel – responsible for the safe operation of large vehicles
  • Scaffolders and riggers – working on elevated structures or temporary works
  • Confined space workers – entering tanks, vessels, or restricted areas
  • Offshore personnel – working on platforms or remote locations
  • Railway workers – operating on or near active tracks

For organisations employing individuals in these safety-sensitive roles, arranging a SEQOHS-accredited Safety Critical Medical ensures assessments are tailored to the specific risks of the role. These evaluations help protect employees, maintain regulatory compliance, and reduce the likelihood of workplace incidents.

By prioritising medical fitness assessments aligned with HSE guidelines, CDM 2015 regulations, and industry best practice, employers can demonstrate due diligence while safeguarding both their workforce and operational reputation.

Schedule Your SEQOHS Safety Critical Medical

Booking a SEQOHS-accredited Safety Critical Medical is straightforward and designed to fit your operational needs. The process typically involves:

  1. Contacting your occupational health provider via website or phone
  2. Providing details about the employee’s role and site-specific risks
  3. Scheduling an appointment on-site or at a clinic
  4. Receiving a comprehensive medical report with fitness certification

Flexible options are available for group bookings, mobile assessments, and follow-up evaluations, ensuring your workforce is fully supported.

Don’t Compromise on Safety or Compliance

In high-risk sectors such as construction, rail, energy, and utilities, SEQOHS-accredited Safety Critical Medicals are more than best practice—they are essential for maintaining robust occupational health and safety compliance. Using a fully accredited provider ensures that employees undergo thorough, role-specific assessments in line with clinical and legal standards.

This proactive approach safeguards employee wellbeing, reduces the risk of workplace accidents, minimises downtime, and helps protect your organisation from regulatory fines or insurance issues.

Investing in SEQOHS Safety Critical Medicals demonstrates a clear commitment to workforce health, safety, and compliance with HSE guidelines and CDM 2015 regulations.
