Most workers in the UK over the age of 16 are legally entitled to a minimum rate of pay, called the national minimum wage. An independent body called the Low Pay Commission (LPC) each year reviews this rate and passes their recommendation to the government, who then set and enforce the rate. With few exceptions, the minimum wage is the same for all types of work and all kinds of business. The current amount for people over 22 years of age is 6.80 per hour. The rates for younger workers are less. However, the following groups are not entitled to receive the minimum wage: workers under school leaving age, the genuinely self-employed, some apprentices, au pairs, armed service personnel and voluntary workers. Also agricultural workers have a separate minimum rate of pay set by the Agricultural Wages Board.
