Health surveillance is a scheme of repeated health checks used to identify ill health caused by work, especially where employees are exposed to known hazards such as noise, vibration, respiratory sensitisers, skin irritants or other substances hazardous to health.
It does not replace risk assessment or control measures – instead, it confirms whether those controls are working in practice, gives early warning when they are not, and helps you take action before minor health effects become long‑term problems.
Clarity designs health surveillance around your specific workplace hazards and exposure profiles, not generic templates. We use your risk assessments to identify who needs surveillance, for which risks, and at what level, ensuring programmes are proportionate, defensible and aligned with HSE and COSHH guidance.
We deliver surveillance through a mix of on‑site clinics, mobile medical units and clinic network appointments, making it easier to reach the right workers across multiple sites and shift patterns without excessive downtime or travel.
Our reporting is structured to support follow‑up action, continuous improvement and audit readiness. You get clear outcomes, recommendations and trend information so you can see where controls are working, where they need improvement, and where further investigation is required.
Health surveillance can sit alongside management referrals, safety‑critical medicals and other occupational health services, giving you a more coherent, cost‑effective approach to managing work‑related health risks across your organisation.
Based on your risk profile, a Clarity health surveillance programme can include some or all of the following:
Audiometry – hearing checks for workers exposed to hazardous noise.
Respiratory surveillance and spirometry – questionnaires and lung function tests where workers may be exposed to respiratory sensitisers, fumes or dusts.
HAVS surveillance – structured assessments for employees using vibrating tools or machinery.
Skin surveillance – checks for workers exposed to irritants or sensitisers that can cause dermatitis or other skin conditions.
Vision screening – eyesight checks where visual demands are safety‑critical.
Biological monitoring – where appropriate, to confirm how well controls are preventing uptake of certain substances.
Each programme is tailored to the hazards identified in your risk assessments and to the sectors and roles you operate in.
Health surveillance is typically required when:
Workers are exposed to a hazardous substance or agent linked to a known disease or adverse health effect.
There is a reasonable chance that the disease or effect may occur in the conditions of work.
There are valid methods to detect early signs of the disease or effect.
This often applies where there is exposure to:
Noise and vibration
Respiratory sensitisers and irritants
Substances that can cause dermatitis or other skin disease
Certain metals, solvents and other agents with systemic effects
Clarity can help you interpret your risk assessments and regulatory requirements to determine where health surveillance is necessary and what level is appropriate.
A well‑designed health surveillance programme helps employers to:
Detect work‑related ill health at an early stage so steps can be taken to treat the condition and prevent further damage.
Check that control measures are effective and highlight lapses or gaps.
Provide data to evaluate health risks and refine risk assessments.
Give employees a route to raise concerns about how work may be affecting their health.
Reinforce training and education on the use of protective equipment and safe working practices.
Health surveillance does not remove the need to manage risk at source, but it does provide essential feedback on whether those efforts are protecting people as intended.
For health surveillance, employers need a partner who will challenge, innovate and stay accountable where health risk, operations and legal duties intersect.
We challenge when surveillance is missing, mis‑focused or overly generic, and help employers re‑align programmes around real hazards and roles.
We innovate in how surveillance is delivered – using on‑site, mobile and clinic‑based options, plus smart scheduling, to minimise disruption while maintaining coverage.
We grow by helping clients reduce work‑related ill health, improve their control measures and build healthier, more resilient workforces over time.
We are driven to deliver – responsive with planning, reliable in delivery and clear in reporting, so you always know where you stand.
Collaboration drives us forward as we work with health and safety, HR, occupational hygiene and managers to integrate health surveillance into everyday operations.
We are energised by health and accountable to each other, bringing care, consistency and professional judgement to every assessment and every programme.
If your workforce is exposed to noise, vibration, chemicals, dust or other hazards, Clarity can help you design and deliver a health surveillance programme that protects people, supports compliance and fits the way your business really operates.
Health surveillance is a legal requirement when employees are exposed to certain health risks at work, such as noise, vibration, hazardous substances or specific biological agents. In these cases, employers must implement suitable health surveillance to monitor health over time and demonstrate that risks are being managed.
The frequency of health surveillance depends on the type of exposure, regulatory guidance and your risk assessment. Some checks are annual, others may be more frequent in the early stages or when risks change. We work with you to define an appropriate schedule for each group.
Yes. Many employers choose on‑site health surveillance or mobile medical units so large groups can be seen in one visit, reducing travel time and keeping employees closer to their work areas. We also offer clinic‑based and remote options where they are more practical.
