Is there any premium or fast track service for Naturalisation?

Sorry, may sound a daft question, read few topic and online but can't find answer. Hence asking here.

My missus is due naturalization, since she got ILR and I am BC from 2017. She got free UKVCAS appoinent for 8th November. I was wondering if there is any earlier or fast track process where by paying premium would assure response in 1 day/5 days or a month max.

Appreciate any guidance on the same.

No.. but decisions are normally a month. Check the month posts for timelines.

Thank you. That's a relief.
