work expenses

Hi i would like help to understand which expenses i can claim for. i have worked away from home on a temporary work placement. the job lasted about 3 months, i was paid paye by an agency who i worked for on site for another company.

Hi locsel,
The expenses that you can claim as an employee are different to those of someone who is self- employed.
As an employee, have a look here:
Claim tax relief for your job expenses
If you are self employed, have a look here: 
Expenses if you're self-employed

Thank you.
