First British Passport, will they fold my British Naturalisation certificate?

[RoyalCitizen]

Hi there,

I have read that in the past they've been folding applicants' British Naturalisation certificates even after sending a cover letter asking for not doing so. Some applicants even provided pre-paid A4 envelops so that they wouldn't fold their certificates, however they folded it anyway.

Has that changed recently or it's still the same misconduct of our documents?

If I request to not fold mine and provide a prepaid tracking envelope, will it be folded?

Cheers!

In my case the certificate was sent back in a plain A4 size envelope. The TNT delivery drivery folded it to post through the letterbox on the door. Wasn't creased though, and to be honest, I didn't mind much.
