Question to the HM Treasury:

To ask Mr Chancellor of the Exchequer, how many investigations for National Minimum Wage non-payment have resulted in the issue of a notice of underpayment in each month since October 2013.

The Government takes the enforcement of the National Minimum Wage (NMW) very seriously. HM Revenue & Customs (HMRC) review every complaint that is referred to them by the Pay and Work Rights Helpline. In addition, HMRC undertake targeted enforcement on employers across the United Kingdom who are more likely to be not paying NMW.

HMRC does not capture complaints or the outcomes of its investigations by reference to Government regions, constituencies or county. Work relating to a specific geographical area is not always done by the NMW team based in that area. Additionally, notices of underpayment are issued to a company's head office address, but may include workers from a number of different operating sites.
