Based on the information outlined I would suggest:
- look at consolidating Pension 2 into new arrangement, subject to the annual management charge under your new scheme being no more expensive and that you get an allocation rate of at least 100%. The advantage is that you have more control and can adopt a single investment strategy.
- a retirement bond could give a similar result (and perhaps allow a more diversified investment strategy) but charging structure needs to be examined
- deciding what to do with your DB benefit is much more complicated. You could just leave it as is (assuming the scheme is well funded). But you could also look at opting for a Transfer Value into your new pension scheme. But that would very much depend on whether the DB scheme will offer a full transfer, what that transfer value amounts to and whether the transfer value will likely provide similar benefits by retirement. It would be a much more complicated decision process, one requiring expert advice.
Hope this is of some help.
