What is Health Surveillance?
It’s a system of ongoing health checks designed to catch early signs of work-related ill health. Unlike voluntary wellbeing programmes, surveillance is mandated by law wherever employees are exposed to specific workplace hazards. It does two things: it protects individual workers by detecting problems early, before they become disabling or irreversible, and it validates whether your existing control measures, ventilation, PPE, noise barriers, vibration-dampened tools, are actually working.
Core surveillance services
Hearing Conservation (Audiometry)
For employees exposed to noise above the lower exposure action value of 80dB. Required under the Control of Noise at Work Regulations 2005. The test combines an otoscopic ear examination with a calibrated audiometric assessment to detect early noise-induced hearing loss, a condition that is permanent, progressive, and entirely preventable with proper controls and monitoring.
Results are categorised against HSE L108 standards, allowing you to track trends across your workforce and identify whether your hearing protection programme is effective. Employees showing early deterioration can be reassessed, moved to quieter tasks, or provided with better PPE before the damage becomes significant.
Respiratory Health (Spirometry)
For workers exposed to respiratory sensitisers like isocyanates, flour dust, wood dust, or welding fumes. Required under the Control of Substances Hazardous to Health Regulations 2002. Spirometry measures lung volume and airflow to detect early occupational asthma or chronic obstructive pulmonary disease (COPD) before symptoms become disabling.
Early detection is everything with respiratory disease. By the time an employee notices breathlessness during physical tasks, lung capacity may already be significantly reduced. Regular spirometry catches functional decline at the subclinical stage, when intervention, reducing exposure, improving ventilation, changing PPE, can prevent the condition from progressing.
Hand-Arm Vibration Syndrome (HAVS)
For anyone using vibrating tools above the Exposure Action Value. Required under the Control of Vibration at Work Regulations 2005. HAVS causes permanent damage to blood vessels and nerves in the hands and fingers, leading to pain, numbness, and loss of grip strength that can end a person’s ability to work in their trade.
We deliver the full tiered pathway from Tier 1 questionnaires through to Tier 4 physician assessment. Tier 1 screening identifies employees reporting symptoms. Tier 2 clinical assessment confirms the diagnosis and grades severity. Tiers 3 and 4 involve specialist physician evaluation for advanced cases. Your results are recorded against the standardised grading system so you can track progression and adjust exposure limits accordingly.
Skin Surveillance
For roles involving regular contact with irritants such as epoxy resins, solvents, metalworking fluids, or industrial cleaning agents. Visual skin inspections under COSHH regulations detect early occupational dermatitis before it becomes a chronic condition, a compensation claim, or a reason for an experienced employee to leave their role.
Skin surveillance is the most overlooked surveillance requirement. Many employers focus on noise and respiratory hazards while missing the fact that their workforce is developing dermatitis from substance contact that proper monitoring would catch in its early stages.
Why Choose MCL Medics?
The clinic comes to your car park. Staff are tested in 20-minute slots with minimal disruption to shifts. Our mobile units are fully equipped with sound-proof audiometry booths, calibrated spirometry equipment, and HAVS screening capability. We can process large cohorts in a single visit.
HSE-qualified clinicians
Every assessment is conducted by specifically trained occupational health professionals. Your Fitness for Work certificates are legally defensible and audit-ready. Our technicians hold current certification in audiometric testing, spirometric assessment, and HAVS screening.
Complete record management
We maintain long-term health records and trend data, giving you the evidence base for HSE audits, risk reviews, and compensation claim defence. Records are stored securely and retrievable for the duration of each employee’s employment and beyond, as regulations require.
SEQOHS-accredited governance
All surveillance is delivered within MCL’s accredited governance framework by directly employed clinicians. Your records are maintained to the standard that HSE inspectors expect, and your programme is designed to demonstrate compliance, not just perform tests.
Designing Your Surveillance Programme
Not every employee needs every test. Surveillance is risk-based, which means the programme should be driven by your risk assessments, exposure data, and the specific hazards present in each role. We work with your safety team to design a proportionate programme that covers your regulatory obligations without over-testing employees who do not need it.
What This Means for Your Business
Health surveillance is not just a compliance obligation. It is an early warning system that protects your workforce and your balance sheet. Noise-induced hearing loss, occupational asthma, and HAVS are all progressive conditions that become permanent and compensable if not detected early. The cost of a single occupational disease claim including compensation, legal fees, and increased insurance premiums, dwarfs the cost of the surveillance programme that would have caught it.
HSE enforcement adds another dimension. An improvement notice for inadequate surveillance disrupts operations and creates a compliance record that affects future contract bids. A prosecution carries unlimited fines and director liability. Proper surveillance, conducted by qualified clinicians within an accredited governance framework, is the most cost-effective protection available.
The conditions health surveillance detects, noise-induced hearing loss, occupational asthma, HAVS, are progressive. The longer you operate without compliant monitoring, the greater the risk that an employee’s condition has advanced beyond the early stage where intervention is effective, and into the territory where compensation claims become inevitable.
