Before you agree to a job offer you should know that in United Kingdom there is a minimum salary which should be paid, that depends on your age. (doesn’t apply if you are doing voluntary work though…)
For example if your age is between 16 and 17 the minimum salary for you is £3.40 per hour. If you are the age of a student which is 18-21 you have to be payed at least £4.60 per hour, and finally if you are over 22 your minimum should be £5.52 per hour.
In some companies that provide accommodation the minimum wage can be smaller, this is called accommodation offset.
Regarding the maximum salary you would like to ask. The sky is the limit but to be more realistic here are some annual salary medians for different positions in London:
- Personal assistant – £26.352
- Software engineer, developer – £31.500
- IT consultant – £39.515
