From 1 April 2026, workers must receive at least the legal National Minimum Wage rate for their age and, where applicable, their apprentice status; rates can differ, so check the latest figures on GOV.UK. Your employer should count eligible working time correctly, provide an itemised payslip and keep records. Unlawful deductions, unpaid working time or being paid below the correct rate may mean you are owed arrears. Raise concerns with your employer or Acas, and you can report suspected breaches to HMRC, which decides cases based on the evidence.
