Lung Function Tests (Spirometry):

Respiratory health remains one of the most critical – and often overlooked – aspects of occupational health across the UK. In many industries, employees are regularly exposed to airborne hazards such as dust, fumes, chemicals and respiratory sensitisers that can significantly affect lung function over time.
At Flex Health, we provide Occupational and Workplace Spirometry as part of our Occupational Health Surveillance Services, supporting employers to identify early signs of respiratory disease, meet UK regulatory requirements, such as COSHH (Control of Substances Hazardous to Health), and protect long-term workforce wellbeing.
Delivered directly at your workplace via our mobile health surveillance units, Lung Function Testing at Flex Health goes beyond a tick-box exercise. It is a clinically-led service that enables employers to identify early changes in respiratory health and safeguard workforce wellbeing.
Why Spirometry Matters in Occupational Health
In occupational settings, Lung Function Testing forms part of a structured respiratory health surveillance, helping to monitor employees exposed to harmful substances that may affect breathing and lung performance.
Many occupational lung diseases develop gradually. By the time symptoms such as coughing, breathlessness, or wheezing appear, significant damage may already have occurred.
Occupational Spirometry Testing enables employers to:
- Detect early changes in respiratory health
- Monitor lung function over time
- Identify workers at risk of respiratory diseases
- Reduce ongoing exposure and deterioration
Without structured respiratory surveillance, employees exposed to hazardous substances may continue working in conditions that progressively damage their lungs.
Workplace Exposure and Respiratory Risk
Across many industries, workers are exposed to airborne hazards that can affect the respiratory system. These exposures may not cause immediate symptoms but can lead to long-term respiratory disease if left unmanaged.
Common workplace respiratory risks include exposure to:
- Wood dust in construction and joinery
- Welding fumes and industrial emissions
- Cleaning agents and chemical vapours
- Grain dust and food production particles
- Laboratory animals and biological agents
- Respiratory irritants such as sulphur dioxide
- Chemicals, glues, resins, and other hazardous substances
Prolonged inhalation of these substances can increase the risk of occupational asthma, Chronic Obstructive Pulmonary Disease (COPD), and other occupational lung diseases.
Where these risks are identified through a workplace risk assessment, employers have a legal and ethical responsibility to implement appropriate control measures and respiratory health surveillance, including Lung Function Testing.
Our Approach to Spirometry Testing
At Flex Health, we combine clinical expertise with practical workplace delivery to provide high-quality Spirometry Services across the UK.
Our approach is designed to ensure accurate testing, minimal disruption, and meaningful outcomes for employers and employees alike.
Delivered nationwide via our mobile health surveillance units, our service provides on-site Lung Function Testing directly within your workplace, ensuring efficient access to high-quality occupational health support.
1. Accurate Results, Reliable Testing
Our Spirometry Tests are carried out using calibrated equipment to ensure accurate and consistent results. Testing is delivered by trained occupational health professionals with experience in respiratory health surveillance.
The process is quick, straightforward, and completely non-invasive, allowing employees to complete testing comfortably while producing reliable clinical data. We follow recognised clinical standards to ensure each assessment is repeatable and suitable for long-term monitoring.
2. Structured Testing and Monitoring
Our Occupational Lung Function Testing supports both baseline and ongoing monitoring, helping to identify changes in lung function over time.
Where concerns are identified, we provide clear guidance on appropriate next steps and further investigation in line with best practice.
3. Workplace and On-Site Testing
We understand that accessibility is key, which is why at Flex Health, we deliver workplace Spirometry both on-site and within clinic environments, allowing businesses to minimise disruption while ensuring employees receive essential health surveillance testing.
This is particularly valuable for organisations with:
- Large workforces
- High-risk environments
- Shift-based operations
- Multiple sites across the UK
4. Clear Reporting and Compliance Support
Following testing, employers receive structured reports that provide:
- Lung function results
- Identification of any changes or potential concerns
- Recommendations to support exposure control measures
- Guidance on appropriate next steps, where required
Our reporting is designed to support employers in meeting compliance requirements, maintaining accurate health records, and making informed decisions around workplace safety and employee health.

Early Detection and Prevention
One of the most important aspects of lung function testing is early detection.
Respiratory diseases such as COPD and occupational asthma often develop over time. Without monitoring, lung damage can occur gradually and without obvious warning signs.
Regular Spirometry Testing allows employers to:
- Detect early changes
- Prevent further deterioration
- Improve workplace controls
- Protect long-term employee health
Early intervention is key to reducing occupational risk.

Supporting Healthier Workplaces
Occupational lung disease does not only affect individual employees, but it can also impacts the wider workforce, productivity and business performance.
Poor respiratory health can result in:
- Increased sickness absence
- Reduced productivity
- Long-term health issues
- Increased operational costs
By investing in regular Respiratory Health Surveillance, businesses demonstrate a commitment to safety, compliance and employee wellbeing.
