I would suggest you contact RM pensions in Chesterfield to check if you can do as I say, if so you should also be able to get a quote of the value from them.
But from some of you previous posts, I notice you are concerned by the impending closure to future accruals of the RMPP and it being replaced by an inferior DC scheme. So why do you want to transfer out of a good salary based scheme into another type of DC pension and lose your accrued benefits?
What you’ve built up so far in the RMPP(section c) probably won’t seem very much in money terms, but that will continue to increase with inflation until you draw it.
From the photo you posted here: viewtopic.php?f=27&t=75232&p=736508#p736508
you’ve already got £1,700 in index linked pension as of 31/3/15. This years (2017) statement will probably say about £2,300. If you wanted to buy a similar index linked income with spouses benefits using a DC pension pot, you would need approximately £90,000. That’s a damn sight more than your RMPP pension would be worth if you transferred it.
