In Scotland, the minimum hourly rate for a Modern Apprentice is £6.40 at 16 years old. This translates to £12,480 a year. This is under the personal tax allowance amount so you wouldn't pay income tax (although you would have to pay NI contributions but these should come to less than £250 a year on this wage). The wage rises as you get older and gain experience and once you're trained you would be on the normal salary for the role.
