The introduction of SIPPs (Self-Invested Personal Pensions) really opened up options for retirement saving
in the UK. If you live in the UK and are looking for flexibility and control over your pension then a SIPP
really is the way to go for you.
If however you are leaving the UK, or you have already left the UK and you will be a non-UK resident
for 5+ years, then the benefits of a QROPS transfer generally outweigh SIPP benefits.
