UK, Ireland / Getting married to a Polish Citizen in the UK [371]

Hi, I'm Brazilian and my boyfriend is Polish, we both live and work in UK. We have been dating for only 8 months but we want to get married. He still don't have a permanent UK resident passport, and only I have only more 6 months visa to stay and work in UK. Should we get married in Poland, so I can get a full visa and be entitled to work in UK? or should we marry in UK, and then register in the embassy of poland in uk?

Can somebody help us? Much appreciated. Thanks!
