Obtaining a copy of certificate of enhanced protection

I have lifetime allowance enhanced protection. It is active and I can check the Scheme Administrator Reference and the Protection Notification Number, which check out on-line as valid. But I do not have the physical certificate, nor does the on-line information I am able to access through the Government Gateway disclose the protected lump sum. Search as I may, I cannot find out how to obtain a copy of enhanced protection certificate with the complete information which I can provide to my pension provider to confirm the amounts. I would be grateful if someone could tell me how to obtain a full copy of my enhanced protection certificate. Thank you.

Hi,
You can see guidance here:
PTM176310 - Lump sum and lump sum and death benefit allowance: Enhanced protection: Overview
Thank you.

Thank you, but this does not answer my question. How do I obtain a copy of my protection certificate, which contains the amount of the protected lump sum amount? Thank you.
