"It’s a common misconception that students don't have to pay income tax in the UK. They do – it's just that their total income usually doesn't take them over their personal allowance (the amount you can earn in a year without having to pay tax)."
"The bad news is that while students don’t pay tax on grants or student loans, they are still liable for income tax and National Insurance (NI) in the same way as other workers."
