If you inform the JC that you have found work before you close your claim, they can pay your travel fee's and give you an amount (it's up to them to decide how much) of money towards things like food and expenses. This must be done before you sign off though, as once you've signed off, there isn't anything they can do for you as effectively, your claim has been closed.
You can also get money towards clothes for an interview or anything you'd need for that specific job (within reason) such as PPE or a uniform.
