Glasgow no thanks

The no thanks in this advert headline is in the position where the salary is usually quoted.

In the context of OS&H in the UK the abbreviation HSE surely means Health & Safety Executive. On this basis, one answer to your thread title question is that a HSE inspector nowadays is worth whatever revenue he or she generates for HM Treasury via Fees For Intervention (FFI) ! No doubt the inspector's salary and travelling costs, etc. somehow need to be considered, presumably as deductions from the revenue generated. :-)

On a provocative note, some people think the use of HSE as an abbreviation for 'safety, health & environment' is ambiguous, misleading, or plain daft, especially as such (mis)use only started some or more years AFTER the Health & Safety Executive came into existence in 1975.

p.s. As an aside, HSE has different meanings in other professional fields. For example, medical people probably tend to think of Herpes simplex encephalitis, while computer experts think of high speed ethernet and physicists/engineers envisage hydrostatic equilibrium.
