To be able to commute benefits from a defined benefit scheme on triviality grounds, the total value of all pension rights cannot be more than £30,000, so at first sight it would appear he couldn't.
However it is possible for non-occupational pension plans (e.g. personal pension plans, stakeholder pension plans, s.32 transfer plans) as well as occupational schemes to be commuted if the member is 55 or over, the amount paid is no more than £10,000 and it extinguishes all rights in the arrangement. It doesn't matter what the value of your other pension rights are. For non-occupational plans, you can do this three times in your lifetime.
So Sanjit could commute his personal pension plan and his stakeholder pension plan under these rules. This then just leaves his pension rights in the defined benefit scheme. As this is not worth more than £30,000, the defined benefit scheme rights could then be commuted on triviality grounds.
