Your account will be with 6Communications @JohnSummers here https://6communications.com/services/mobiles/and they should be able to give some advise.
This question has been raised before with OneCom and it's a difficult one for sure. As your account is with a third party company, you would need to obtain a PAC from 6Communications and port the number out, as you can't port Vodafone to Vodafone, you would need to port to any other network as PAYG and port back in directly with Vodafone on a new personal account. Unfortunately, this will incur any early termination charges from 6.
It won't help but if you were directly with Vodafone you would simply only need to complete a transfer of ownership from business to personal.
The other alternative is to wait until the contract with 6 reaches it's minimum term or take out an additional personal number directly with Vodafone.
No doubt this thread will be picked up by the Social Team here on the forum and they may have a better solution.
