Inside IR35 Occupational Health Contract Jobs

As a contract Occupational Health, you are hired to deliver workplace health assessments, fitness-for-work evaluations, health surveillance programmes, and strategic occupational health advice to employers. Contract engagements cover pre-employment health screening, management referrals for sickness absence, Display Screen Equipment assessments, workplace health promotion, and compliance with statutory health surveillance requirements under COSHH and other regulations. Occupational Health contractors work within in-house OH teams at large employers, for occupational health service providers, and as independent practitioners supporting multiple organisations.

Occupational Health contractor roles require registered nurse or physician qualifications with specialist occupational health training. OH nurses typically hold an occupational health nursing degree or diploma and NMC registration with a specialist community public health nursing qualification.

Familiarity with occupational health case management systems such as Cohort, Meddbase, or Cority is commonly expected.

The Occupational Health contract market is a specialist market with steady demand driven by employer obligations under the Health and Safety at Work Act and the growing focus on employee wellbeing. The NHS, defence, manufacturing, and construction sectors are the most consistent sources of demand. Post-pandemic, the scope of occupational health has broadened, with employers investing more in mental health support, musculoskeletal assessment, and health promotion programmes. The pipeline of qualified OH practitioners is relatively constrained, supporting firm rates for experienced contractors.

IR35 is UK tax legislation that determines whether a contractor is genuinely self-employed or working in a manner that resembles employment. When a contract is classified as inside IR35, income tax and National Insurance are deducted at source, typically via an umbrella company or agency PAYE. Headline day rates on inside IR35 engagements are generally higher than equivalent outside IR35 roles to account for the tax and employment cost structure.

Inside IR35 determinations are made where the working arrangements are considered to resemble employment, based on factors including the level of client control, the absence of a genuine right of substitution, and the presence of mutuality of obligation. Since April 2021, the end client is responsible for making this determination for medium and large private sector organisations. Many employers in financial services, government, and professional services assess the majority of their contractor engagements as inside IR35.
