I'm reluctant to comment, having been retired 10 years - rules and regulations in the world of pensions change so often. So just a few comments:
> it is possible to transfer occupational pensions abroad, BUT typically it is complicated by virtue of the tax office regulations, so specialist advice is required [and that costs money].
> you haven't said what sort of company pension it is, were it to be a 'defined benefit' pension scheme, then the benefits will be revalued annually until Normal Retirement Date under the scheme. The point here is that should you intend to return to this country and retire here, this pension would come in handy. Who knows what foreign benefits you will have earned?
> the bottom line is that, yes, you can transfer your pension abroad, it may be costly, and you may well not be able to take the cash value when abroad. Certainly at one time the tax office insisted one could, broadly, only do abroad what one could do here.
> as to taking cash here - no comment!
Perhaps I should have said nothing at all!
