I might've made a mistake on my passport renewal application.
I've applied online (and I've yet to mail my declaration form) and I might've erroneously ticked a box for "uncancelled non-British passport". I may have ticked it thinking it was referring to my current/expiring passport (obviously I didn't read it thoroughly enough).
Should I contact (email or phone) the HM Passport Office first before mailing my form or mail it first then let them know about the error when they think something is missing?
