You can apply for jobs in the UK while still in Poland, just mention that you're currently in Poland but looking to relocate to the UK (I'm guessing London?).

You can apply for jobs in the UK while still in Poland, just mention that you're currently in Poland but looking to relocate to the UK (I'm guessing London?). Some companies (especially smaller ones) will only follow-up with local candidates, but plenty of medium and large size ones are happy to engage with candidates looking to move.
