This is the sort of situation which fueled Brexit voters
At this stage, there is no Polish person in the UK without basic English, unless they have learning difficulties/special educational needs. In Ireland, I never met a Polish person, even working in a Polish shop who didn't speak basic English. Even way back, when they first began arriving in signifcant numbers, they made a real effort to learn English as quickly as possible.
I have to say, without being sexist, that the men were much more active in that respect. I suppose it makes a man feel 'weak' if he can't communicate but the first wave of women, who mostly came over to join their men, felt they didn't really need to learn as their man could do the talking. However that really changed once they began having children. They wanted to be able to deal with all the situations that arise when you're a mother and need to discuss your child with teachers, doctors etc. Also, after a time, more educated, professional Polish women began arriving on their own and wanted to work in their professions.
I knew several Poles who passed their professional exams in Ireland in areas like accountancy, banking, etc. and several working in various roles in government departments. The level of English spoken by Poles in Ireland anyway, is really very good at this stage.
