Now that I have the advantage of seeing your last two comments:
Your tax codes are correct. What is probably driving you nuts is your employer's pay system.
Just check that tax on Contract 1 is in fact around £130, not £221.
Last, you are getting basic personal allowance. I would have thought the nature of your work would involve being a member of one or more professional
bodies, and you may be able to claim subscriptions against tax. See link, check under "N" for nursing bodies.

You can also claim for the last 4 years if no allowance has been given. (it used to be 6!)
