UK Personal pension

I'd just suggest that you are extremely careful in what you do here. One important factor to consider is that a QROPS is best for someone who is never going to return to the U.K. i.e. if you eventually intend to retire in the U.K. Then transferring your pensions into a QROPS is probably not a good idea.
The second point is that transferring a pension generally incurs very significant charges, and can seriously impact the actual value of the fund you have accrued. Get in writing a detailed breakout from any financial advisor exactly what their charges and commissions will be on any transfer. If your existing three pension schemes are all relatively small, then by the time each one has been transferred into the QROPS, you may lose significant amounts of your accrued pension.
All in, just be very careful, and ideally get at least two or three proposals from different advisors before you make a choice.
