Pension certificate of enhance protection

I have a certificate of enhanced protection which states my tax free lump sum is 13%. I have not yet taken any benefits from my pension fund but would like to know if the lump sum which I can now take is 13% of the value of the fund today or is it 13% of the value of the fund on 6 April 2006. In both instances the amount would be in excess of the current lump sum allownace.

Hi Freddie,
Please refer to guidance at Pensions Tax Manual: PTM176310.
Thank you.
