Employers must make sure their staff receive at least the National Minimum Wage or National Living Wage rate that applies to them. The correct rate depends on the worker's age and, in some cases, whether they are an apprentice.

Since 1 April 2026, workers aged 21 and over are entitled to the National Living Wage of £12.71 an hour. The rate for workers aged 18 to 20 is £10.85, while workers under 18 are entitled to minimum of £8 an hour. 

Apprentices also have a minimum rate of £8 an hour, but this does not apply throughout their apprenticeship. An apprentice is entitled to the apprentice rate if they are under 19, or if they are 19 or over and in the first year of their apprenticeship.

Once an apprentice aged 19 or over has completed the first year of their apprenticeship, they become entitled to the minimum wage rate for their age. For example, a 21-year-old apprentice in their first year is entitled to £8 an hour, but after completing that first year they must receive at least £12.71 an hour.

Employers who fail to pay the minimum wage can face significant financial penalties. HMRC can require arrears to be repaid and impose penalties of up to 200% of the underpayment, subject to the applicable rules. Serious cases can also result in criminal prosecution.

Employers should therefore review rates regularly, particularly when employees have a birthday or apprentices reach the end of their first year.

The minimum wage rates change every 1 April, so payroll systems should be updated promptly to avoid underpayments.
