Hi. My name is*****'m looking at your question now and will post my answer or ask for more information here in a short while.
You may be due a tax repayment as you won't have used all your personal allowance for 2015/16.
Assuming you aren't in the self-assessment system, you should receive a P800 tax calculation by the end of September 2016 if you are due a tax repayment. Take a look at the notes here. You could try to accelerate that process by calling the number here and asking to have your 2015/16 tax position reviewed and a P800 issued as soon as possible.
I hope this helps but let me know if you have any further questions.
I have to go out but will be back in about 30 minutes to answer any follow up questions that you may have.
