The National Minimum Wage rates are reviewed each year by the Low Pay Commission and from 1 October 2011:

•the main rate for workers aged 21 and over will increase to £6.08

Therefore based on a 40hr working week that equals 243.2 GBP per week x 52 = 12646.4GBP per year.

So it's actually an illegally low wage.Unless you fall into these catogories - http://www.direct.gov.uk/en/Employment/Employees/TheNationalMinimumWage/...
