The national minimum wage for adults aged 21+ has increased by 12p an hour to £6.31.
The rise, which took effect yesterday and was first announced in April, follows the recommendations of the independent Low Pay Commission.
The rate for 18-20 year-olds is increasing by 5p to £5.03 an hour, while the 16-17 year old rate is rising 4p to £3.72.
The BBC reported that The Resolution Foundation, a think tank which focuses on standards of living, said that the minimum wage was in effect falling - in spite of the increase - because of the pace of inflation.
Inflation, measured by the consumer prices index (CPI) fell to 2.7% in the year to August, from 2.8% in July.
It means prices are still rising faster than wages, which rose by 1.0% on average over the same period.
