Minimum wage is £5.03 - on a 35 hour week, that's £9k a year. I you're over 20, that rises to £12k/year.

So, better than minimum wage.

If you have several years experience, it's probably not the job for you. If, however, you've just left school or are taking a break from university - I think it's a pretty fairly paid way to get your foot in the industry.
