you should be allowed three options.
a) leave funds in current scheme and take reduced pension from that scheme at retirement age.
b) take some form of personal insurance bond. Not sure what that provides for, but I think it is similar to a
c) transfer to new employer.
you need to consider carefully the options. if your current pension is a defined benefit and the new one is similar, it may be better to transfer to the new scheme.
defined benefit schemes are getting scarcer so you really only ahve the one chance to make this critical decision.
