Supporting docs:
I sent in my naturalisation certificate, a colour photocopy of my foreign
passport (all pages) and a cover letter explaining that I needed my
passport for work. I did ask via chat if that was ok and they confirmed so.
I also sent a prepaid, self-addressed "do not bend" special delivery envelope for the return of the naturalisation cert. I specifically asked in the cover letter for them to use it.
Just in case, I paid the extra £5 for "secure delivery" of my docs at the application stage as well which backfired slightly because the numpties at HMPO packed everything I sent them in their own plastic pouch with the cert on top rather than inside the do not bend envelope... This meant the cert arrived a bit creased but not too badly.
To all of those whose certificates got damaged, a big advantage of choosing "secure delivery" is that HMPO assumes responsibility for any loss or damage. So as long as that's the option you chose you should lodge a complaint and they will ask UKVI to send you a new one (hopefully in a proper envelope!).
