Occupational Health Surveillance.

Follow-up HS Assessments.

Nationwide Health Surveillance for UK Employers.

OH One provides professional health surveillance services to help employers meet their legal obligations, protect employee health, and identify early signs of work-related ill health.

Our experienced occupational health clinicians deliver onsite and workplace-based health surveillance programmes across the UK, supporting organisations of all sizes.

We provide health surveillance services across Manchester, Birmingham, Sheffield, York, Preston, Liverpool, Coventry, and nationwide workplaces throughout the UK.

What is Health Surveillance?

Health surveillance is a system of ongoing health checks designed to identify early signs of ill health caused by workplace exposures.

Where employees are exposed to specific hazards, health surveillance can help detect potential issues before they become serious, support compliance with UK health and safety legislation, and provide employers with valuable information about the effectiveness of workplace control measures.

Health surveillance may be required where employees are exposed to:

  • Workplace noise

  • Hand-arm vibration

  • Ionising radiation

  • Solvents, fumes, dusts, or biological agents

  • Substances hazardous to health (including under COSHH)

  • Work in compressed air environments

  • Skin irritants and sensitisers

  • Safety-critical working environments

Health surveillance is usually carried out by an Occupational Health clinician on the employer’s premises. It may involve clinical tests tailored to the hazards present, alongside an assessment of the employee’s medical history. 

Our Health Surveillance Services

Audiometry (Hearing Tests): Audiometry monitors hearing health for employees exposed to workplace noise. Regular testing helps identify early signs of noise-induced hearing loss and supports compliance with the Control of Noise at Work Regulations.

Lung Function Testing (Spirometry): Spirometry assesses respiratory health where employees are exposed to dust, fumes, vapours, respiratory sensitisers, or other airborne workplace hazards.

Skin Surveillance: Skin surveillance helps identify early signs of work-related dermatitis and other occupational skin conditions caused by chemicals, wet work, cleaning products, or workplace irritants.

Hand Arm Vibration Syndrome (HAVS): HAVS screening monitors employees exposed to vibrating tools and equipment. Early identification can help prevent long-term damage and support compliance with vibration regulations.

Safety Critical Medicals: Medical assessments for employees working in safety-critical roles where fitness for work is essential to protect themselves, colleagues, and members of the public.

General Health Screening: Workplace health assessments designed to support employee wellbeing, identify potential health risks, and promote a healthier workforce.

On-site Health Surveillance Across the UK

Most health surveillance assessments can be delivered directly at your workplace, helping minimise disruption, improve attendance rates, and simplify compliance. Our clinicians can attend your site to undertake assessments efficiently and provide clear management reports and recommendations following completion. In some cases, routine health surveillance highlights results that need a closer look — whether that’s hearing, respiratory health, skin concerns, musculoskeletal issues, or any other change that could affect someone’s wellbeing or safety at work. When this happens, OH One provides a focused Follow-up Assessment service to review the findings in more detail, understand what’s driving the change, and offer clear, practical next steps for both you and your employee. This ensures every result is managed proportionately, consistently, and with the right clinical oversight.

OH One can also arrange Medical Surveillance for High-Risk Hazards, which must be conducted by a doctor. This applies to specific hazards covered under UK regulations, including asbestos, lead, ionising radiation, work with compressed air and other regulated exposures requiring statutory medical examinations.

Frequently Asked Questions

  • Health surveillance may be a legal requirement where employees are exposed to hazards identified through workplace risk assessments. Employers have a duty to protect employee health and may be required to implement health surveillance under regulations relating to noise, vibration, hazardous substances, respiratory exposures, and other occupational risks.

  • Health surveillance is commonly required in industries such as construction, manufacturing, engineering, logistics, transport, utilities, food production, waste management, and other environments where employees are exposed to workplace hazards.

  • Health surveillance is not a pass or fail assessment. If concerns are identified, employers may need to review workplace risks, control measures, training, PPE provision, or working practices. Occupational health advice can help determine any appropriate next steps.

  • Employees can refuse health surveillance. However, employers still retain a legal duty to protect their health and safety. Any refusal should be documented, and employers should seek occupational health advice where necessary to ensure workplace risks are managed appropriately.

  • No. Health surveillance and risk assessments serve different purposes. Risk assessments identify hazards and determine control measures, while health surveillance monitors whether workplace exposures are affecting employee health.

  • Employers should review workplace risks, assess the effectiveness of existing controls, and seek occupational health guidance where appropriate. Early intervention can help prevent health issues from worsening and support employee wellbeing.

  • Yes. Where individuals are exposed to workplace hazards, employers should ensure appropriate health surveillance arrangements are in place regardless of employment status. Responsibilities may vary depending on contractual arrangements and workplace control.

  • Employers should maintain appropriate health surveillance records in line with legal and regulatory requirements. Occupational health providers can advise on retention periods, confidentiality, and compliance with data protection legislation.

  • Health surveillance helps employers identify early signs of work-related ill health, monitor the effectiveness of workplace control measures, and demonstrate compliance with health and safety legislation. Effective health surveillance programmes can help reduce sickness absence, protect employee wellbeing, support risk management, and provide valuable information to improve workplace safety.

  • Health surveillance can help reduce sickness absence by identifying early signs of work-related ill health before conditions become more serious. Early detection allows employers to review workplace risks, strengthen control measures, and provide support or adjustments where needed.

    While health surveillance cannot prevent all health-related absences, it can help reduce the likelihood of long-term sickness absence associated with workplace exposures such as noise, vibration, respiratory hazards, and skin irritants. It also provides valuable information that can help employers improve workplace health, safety, and employee wellbeing over time.

    When combined with effective risk assessments, training, appropriate personal protective equipment (PPE), and occupational health support, health surveillance forms an important part of a proactive approach to workforce health management.
