The National Minimum Wage rate per hour depends on your age and whether you’re an apprentice - you must be at least school leaving age to get it.

2012 (current rate) £6.19 £4.98 £3.68 £2.65
2011 £6.08 £4.98 £3.68 £2.60
2010 £5.93 £4.92 £3.64 £2.50
*This rate is for apprentices under 19 or those in their first year. If you’re 19 or over and past your first year you get the rate that applies to your age.
