We have not made an assessment that would specifically address this question. However, in 2017, the occupational health market was estimated to be worth around £800m a year.
In 2014, 51% of all GB employees had access to occupational health services provided for by their employer.
We have worked with a wide range of stakeholders, including through our Occupational Health Expert Group, to shape measures to improve access to high quality occupational health. We will set out our proposals in a consultation exercise in 2019.
