This is a very good deal for Poles who worked in the UK.
It's the deal of the century! I wouldn't like to try to live off 5,555zl but as one pillar of a pension here it would be OK. I reckon 5.5 from UK state pension, the same again from ZUS, and contributions from dipping into 20 years of maxed out IKZE, PPK and PPO, plus either income from selling off the portfolio or an annuity, one could live pretty well in Poland in one's golden years.
