On Wednesday (12 June) guests can book and can pay nothing further until 90 days before their sailing.
The offer applies to all destinations and all ships with cruises departing on or after 1 January, 2020 and is combinable with Princess’s current Three for Free deal.
Three for Free comprises up to $500 spending money per couple, a complimentary speciality dining experience and a bottle of wine on selected sailings.
As part of the £1 deposit campaign, guests can choose from a range of sailings to regions including Asia, the Caribbean, Australia & New Zealand, Alaska and Hawaii.
Voyages onboard Princess’s soon-to-launch Sky Princess are also bookable, such as a Scandinavia and Russia roundtrip from Copenhagen next year.
An 11-night cruise departs Thursday, 28 May and features calls to Oslo, Berlin, Tallinn, St Petersburg, Helsinki and Stockholm.
Prices lead in from £1,699pp, with up to $125 onboard spending money per person, a complimentary bottle of wine and free speciality dining.
Tony Roberts, vice-president Princess Cruises UK and Europe, said: “The £1 deposit has proved incredibly popular for our agent partners, with record-breaking Princess Cruises booking days in both the previous years when the offer was available.
“We would like to thank the trade for the great support they continue to give us for £1 deposit day and we have every confidence this year will prove equally successful.
"With the offer including UK-based cruises from Southampton, to far-flung fly cruises on the other side of the world, there’s a wealth of choice available to agents and their customers.”
