Casa, is correctly confirming that UK citizenship takes effect from the date of ceremony when an adult citizen will take the oath & receive their naturalisation certificate;
(certificate dated as day of ceremony).

However a minor (who is registering as a citizen) may, ordinarily, receive their certificate in the mail & it will be dated accordingly.

An older minor (still under 18 years old) may be invited to participate in a naturalisation ceremony by a kindly council official (even at no extra charge);
for example, my daughter was.

The minor will still be a citizen from the date on their certificate (even if they do attend a ceremony at a slightly later date and receive the certificate on that later date).
