Foreign income after leaving UK

I can't decide whether I should file a tax return in England. Last year I lived with my partner in England (he worked). I have never worked in England. In September I moved to Poland. Two weeks later I started working in Poland where I pay taxes. Of course, I submitted the P85 form informing about the change of my address, leaving UK, and taking up work in Poland. Should I submit a tax return for last year and for income received abroad after moving out? Thank you for your time in advance.

Hi,
