The government is determined that everyone who is entitled to the National Minimum Wage (NMW) receives it. If anyone thinks they are not receiving at least the minimum wage, they can contact Acas, in confidence, on 0300 123 1100 or submit a query online using the link https://www.gov.uk/government/publications/pay-and-work-rights-complaints
The government increased NMW enforcement funding from £20 million per annum in 2016/17, to £26.3m in 2018-19. This additional investment enabled a significant expansion of resources dedicated to enforcing the minimum wage: there were 424 staff in post in HMRC’s NMW teams as at 31 March 2018.
In addition, other staff across HMRC contribute to enforcing NMW, including lawyers, technical advisers, and those specialising in criminal investigations. HMRC does not record the specific numbers of those staff involved beyond those identified above.
