There is no maximum amount you can pay an apprentice, but you must pay them at least the National Minimum Wage for Apprentices (currently £4.15 per hour) if they are aged under 19 years old, or over 19 years old and in the first year of their Apprenticeship.
Apprentices are entitled to the minimum wage once they are over the age of 19, or have completed their first year of their Apprenticeship.
