First class mail must be posted by 20 December, and second class mail must be posted by 18 December to ensure delivery in time for Christmas.
As post is not delivered on Christmas Day, Special Deliveries (Royal Mail’s next day service), must be arranged no later than 23 December.
Christmas delivery deadlines vary for destinations overseas. Some international mailing deadlines have already passed. Further information on international mailing dates can be found on the Royal Mail website.
