The Government is determined that everyone who is entitled to the National Minimum Wage (NMW) should receive it.

HMRC enforce the National Minimum Wage (NMW) and National Living Wage (NLW) in line with the law and policy set out by the Department for Business, Energy and Industrial Strategy (BEIS).

The table below provides a breakdown of figures for the total amount of arrears outstanding, number of businesses and the number of workers identified by HMRC for breaches of National Minimum Wage legislation since 2010.

In all cases where employers are found to owe arrears to workers HMRC are able to recover almost all arrears and carry out checks to ensure the money is repaid to the workers in question. Where an employer fails to pay back arrears, HMRC will take legal action through the civil courts on behalf of the worker to enforce the debt. (c, e)

Where an officer identifies arrears for workers, they may issue a Notice of Underpayment (NOU) requiring the employer to pay those workers within a 28-day period. Any worker placed on a Notice of Underpayment must be able to be contacted/traced at the time the NOU is issued. Every effort is made to trace workers, but this is not always possible if for example they have moved and left no forwarding address. HMRC are unable to provide data about workers who were not included on Notices of Underpayment. (f)
