Your Trusted Occupational Health Provider
Sigma Health is a SEQOHS-accredited occupational health provider supporting businesses across the UK. From safety-critical medicals and HGV driver assessments to health surveillance and management referrals, we help companies stay compliant, protect their workforce, and reduce sickness absence. Trusted by businesses in construction, transport, manufacturing and beyond.
As a fully accredited occupational health provider, Sigma Health delivers a comprehensive range of NHS-standard occupational health services designed to meet the needs of UK employers across every industry. Whether you require safety critical medicals for construction workers, D4 HGV driver medicals for logistics companies, HAVS assessments for manufacturing operatives, or fit-to-work assessments for returning employees — our GMC-registered occupational health doctors and NMC-registered nurses are ready to help.
We provide occupational health services nationwide, with clinics across the UK and mobile on-site assessment units available for larger contracts. All assessments are carried out under our SEQOHS-accredited framework, ensuring every report meets the strict quality standards set by the Faculty of Occupational Medicine and fully satisfies your obligations under UK health and safety legislation.
Our occupational health services include safety critical medicals, health surveillance, HGV and driver medicals, management referrals, absence management, fit-to-work assessments, drug and alcohol testing, face fit testing, pre-placement medicals, OEUK offshore medicals and more — all delivered with fast turnaround times, transparent pricing and no hidden costs.
Trusted by UK's Organisations
Sigma Health is proud to work alongside some of the UK’s most respected construction and contracting businesses. From major Tier 1 contractors to specialist subcontractors, our clients trust us to deliver comprehensive occupational health services — from face fit testing and HAVS assessments to respiratory surveillance and workplace medicals — keeping their workforce healthy, protected, and fully HSE compliant.
Building long-term relationships with our clients is at the heart of everything we do at Sigma Health. Whether you need a single assessment or a full occupational health surveillance programme for your entire workforce, you will receive the same level of care, clinical expertise, and commitment to getting it right — every single time.
Keep Your Workforce Working and Your Business Compliant
Every day a worker is absent, unfit, or unsupported by a competent occupational health provider costs your business more than you think — in productivity, in liability exposure, and in the hidden administrative burden of managing health-related absences without clinical guidance. Sigma Health delivers employer-focused occupational health services across the whole of the UK, built specifically around the needs of businesses that cannot afford delays, gaps in cover, or occupational health providers who take weeks to turn around a report. Whether you need safety critical medicals before a worker steps on site, a management referral completed before an absence spirals, or a fit to work assessment that gives you a clear, legally defensible decision — we deliver it fast, we deliver it compliantly, and we deliver it in plain language your managers can act on immediately.
Sigma Health is not a generalist healthcare provider with an occupational health department bolted on. We are an occupational health business built from the ground up for UK employers — with the clinical expertise, the nationwide reach, and the operational speed to deliver the assessments, reports, and certifications your business needs without the delays, the vague language, or the weeks-long turnaround times that make most occupational health providers more of a problem than a solution. If your workforce needs occupational health support, we are ready to mobilise.

Common Questions About Our Occupational Health
If you are an employer trying to understand your occupational health obligations, you are not alone. COSHH, the Noise Regulations, the Vibration Regulations, face fit testing requirements, management referrals, fitness for work — the legislative landscape for UK employers is complex, and the consequences of getting it wrong are significant. The questions below cover the most common enquiries we receive from HR managers, health and safety leads, site managers, and business owners across the UK. If your question is not answered here, contact Sigma Health directly and one of our occupational health team will respond within one working day.
Still have a question that is not covered above? Every workforce is different, every hazard profile is different, and every employer's compliance position is different. What matters is that you get the right answer for your specific situation — not a generic response from a website. Sigma Health's occupational health team works directly with UK employers every day, across every sector, on every type of occupational health requirement from a single safety critical medical to a nationwide rolling health surveillance programme. Pick up the phone, send us an enquiry, or use the form — and we will give you a straight answer, fast.
