Health Surveillance Requirements in the West Midlands: A Guide for Employers
The West Midlands is one of the most industrially dense regions in the UK. Birmingham and the Black Country remain a heartland for automotive manufacturing and metalworking, foundries and fabrication shops sit alongside logistics hubs along the M6 and M42 corridors, and major infrastructure projects such as HS2 and the Midlands Metro extension have brought a wave of construction activity through the region. All of that industrial density comes with a shared legal obligation: where employees are exposed to noise, vibration, dust, fumes or hazardous substances, employers have a duty under UK health and safety law to provide health surveillance.
For many West Midlands businesses, the challenge isn't understanding that health surveillance exists - it's knowing exactly what their risk assessment requires, how often testing needs to happen, and how to keep a programme running properly rather than treating it as a box-ticking exercise once a year. This guide sets out what health surveillance requirements actually look like for employers operating in the West Midlands, the industries most affected, and what a properly managed programme involves. If you're ready to get a surveillance programme in place, our health surveillance services page is the best next step.
What is health surveillance, and when does the law require it?
Health surveillance is the ongoing monitoring of an employee's health where their work exposes them to a specific, identifiable risk - noise, vibration, dust, fumes, skin irritants, or hazardous substances, among others. It isn't a general wellbeing check. It's a targeted, legally defined process designed to catch early signs of work-related ill health before they become a diagnosed condition.
The legal duty comes from several overlapping pieces of UK legislation, all of which apply equally to employers in the West Midlands as anywhere else in the country:
- The Control of Substances Hazardous to Health Regulations 2002 (COSHH) - covering dust, fumes, chemicals and biological agents
- The Control of Noise at Work Regulations 2005 - covering exposure above defined noise action values
- The Control of Vibration at Work Regulations 2005 - covering hand-arm vibration syndrome (HAVS) from vibrating tools
- The Control of Lead at Work Regulations 2002 and the Ionising Radiations Regulations 2017 - covering more specialised exposures
Under each of these, the trigger for surveillance isn't the industry a business operates in - it's the outcome of a suitable and sufficient risk assessment. If that assessment identifies a relevant exposure, surveillance isn't optional. The Health and Safety Executive's guidance on health surveillance is explicit that the duty is ongoing, not a one-off exercise carried out when a business first opens its doors.
Why West Midlands employers carry particular exposure risk
Health surveillance requirements aren't regional in law - the same regulations apply whether a business is based in Birmingham or Brighton. What differs is exposure. The West Midlands has a specific industrial profile that puts a larger-than-average share of its workforce into roles where surveillance is a legal necessity rather than a discretionary extra:
Automotive manufacturing and the supply chain
The region remains one of the UK's largest automotive manufacturing clusters, from vehicle assembly through to the dense network of component suppliers, tooling firms and machine shops that support it. Roles involving metalworking fluids, spray painting, welding and powered hand tools routinely trigger requirements for respiratory surveillance, skin assessment and HAVS monitoring.
Foundries, metalworking and fabrication (the Black Country)
Dudley, Walsall, Wolverhampton and the wider Black Country have a long-standing concentration of foundries, forges and metal fabrication businesses. These environments typically combine several exposure risks at once - noise from machinery, vibration from grinding and finishing tools, and dust or fume exposure from casting and welding processes - which usually means more than one type of surveillance running in parallel for the same employee.
Construction and major infrastructure
With HS2 construction running through the region and ongoing work on the Midlands Metro extension and wider housing and commercial development, construction remains a major employer across the West Midlands. Surveillance requirements here typically centre on noise, hand-arm vibration from power tools, and respiratory risk from silica dust - one of HSE's stated national enforcement priorities.
Warehousing and logistics
The M6, M42 and M54 corridors have made the West Midlands a major logistics hub. While exposure profiles here are generally lower than in manufacturing or construction, noise and manual handling-related surveillance still apply in many distribution and fulfilment environments, particularly where forklift operation or repetitive machine-adjacent tasks are involved.
Health surveillance requirements by exposure type
The table below sets out the most common surveillance types relevant to West Midlands employers, the regulation that triggers them, and the typical renewal interval. Actual intervals should always be confirmed with your occupational health provider based on your specific risk assessment.
| Surveillance type | Legal trigger | Typical interval |
|---|---|---|
| Audiometry (hearing) | Exposure above Control of Noise at Work action values | Annual for first 2 years, then every 3 years if stable |
| HAVS (hand-arm vibration) | Regular use of vibrating tools - see HSE HAVS guidance | Annual questionnaire; clinical review every 1-2 years by tier |
| Respiratory / lung function (spirometry) | Exposure to dust, fumes or other COSHH-regulated substances | Annual |
| Skin assessment | Contact with irritants, solvents, oils, or wet work | Annual (more frequent if symptomatic) |
| Biological monitoring | Exposure to substances absorbed into the body (e.g. lead, solvents) | Set by risk assessment, often every 3-12 months |
| Vision screening | Safety-critical or display screen-heavy roles | Typically every 1-2 years |
| Safety critical medicals | Driving, working at height, confined spaces | Typically every 1-5 years by role |
Employers managing tool-heavy roles should also read our guide on what happens if an employee fails a safety critical medical, which covers a related but distinct process from routine health surveillance. If you already have a programme in place and are approaching a renewal round, our guide to renewing health surveillance in the UK covers what that process should involve.
Worth knowing: a shortened interval can be triggered outside the standard cycle. If an employee's results show an early change, or they report symptoms, a provider may recommend an earlier follow-up rather than waiting for the next scheduled renewal date.
HSE enforcement activity affecting West Midlands employers
Health surveillance sits firmly within HSE's current enforcement priorities. The regulator's stated focus areas for 2025-2026 include silica, dust and wider COSHH risks, asbestos, noise and vibration-related ill health, and health surveillance itself as a standalone inspection theme - alongside guarding and machinery safety. HSE has been explicit that a lack of health surveillance, where a risk assessment identifies the need for it, is one of the most common reasons manufacturing businesses fail to demonstrate compliance during an inspection, particularly smaller firms.
Inspections of this kind aren't limited to any one part of the country. Construction sites, manufacturers and fabrication businesses across the West Midlands fall squarely within the sectors HSE has flagged nationally, and inspectors have carried out targeted, sometimes unannounced, visits at similar sites elsewhere in the UK covering exactly these themes. Where a business can't produce evidence of a properly run surveillance programme - individual records, renewal dates, and a route for acting on abnormal results - an inspection of this kind can escalate quickly into an improvement notice or worse.

FAQs - Health Surveillance
No – the requirement is triggered by a risk assessment identifying a relevant exposure, such as noise, vibration, dust or hazardous substances, not by industry alone. That said, given the concentration of manufacturing, metalworking and construction activity across the region, a much higher proportion of West Midlands employers will find that surveillance applies to at least part of their workforce.
Automotive manufacturing and its supply chain, foundries and metalworking businesses across the Black Country, construction (including HS2-related work), and warehousing and logistics along the M6 and M42 corridors are among the sectors most likely to have surveillance obligations.
It depends on the exposure. Audiometry is typically annual for the first two years, then every three years if hearing remains stable. HAVS surveillance ranges from annual questionnaires to more frequent clinical review depending on tier. Respiratory and skin surveillance linked to COSHH exposures is usually annual. The exact interval should be set by a competent occupational health provider based on your risk assessment.
Inspectors can issue an Improvement Notice requiring the business to put suitable surveillance in place within a set timeframe, or a Prohibition Notice where the risk is considered serious enough to require an activity to stop. Health surveillance is one of HSE’s stated national enforcement priorities, and manufacturing and construction sites are commonly inspected against exactly this requirement.
Yes. We run mobile and on-site clinics for employers across Birmingham and the wider West Midlands, alongside fixed clinic locations, so surveillance can be carried out with minimal disruption to your working day.
Not if it’s handled properly. We formally request historical baseline and follow-up data from your outgoing provider before your first renewal round with us, so trend analysis across previous years isn’t interrupted.
