Cadbury’s Secret Santa Postal Service is back for Christmas 2026. Find one of the Cadbury Secret Santa posters appearing at bus stops, in shopping centres and around town, scan the QR code and, if a bar is available that day, choose a recipient and their favourite Cadbury bar – it is posted to them for free, in secret.

The service runs from 6am on 2 November to 11.59pm on 20 December 2026 with up to 120,000 free bars, released daily. It is open to UK residents aged 18+, one free bar per participant (per mobile number) and a maximum of three per recipient household; bars are dispatched within one to two weeks.

If the daily limit has been reached when you scan, you can enter that day’s prize draw (3 November–16 December) for another chance to send a free bar. Cadbury also makes a donation to its food-poverty charity partner.
