Irish Ferries Promo Codes & Coupons September 2025

Irish Ferries offers several strategic ways to save on your ferry travel between Ireland, Britain, and France. SimplyCodes research has identified the most effective discount opportunities based on booking patterns and promotional cycles.

Time Your Booking Around the January Sale

Irish Ferries runs its biggest promotional event of the year starting on Boxing Day (December 26th) and continuing through January. This annual sale consistently offers the deepest discounts on ferry crossings, particularly for routes between Britain and Ireland.

According to SimplyCodes analysis of Irish Ferries' historical pricing, the January Sale typically provides savings of 20-25% compared to standard fares. These discounts apply to both vehicle and passenger fares across most sailing dates for the upcoming year.

To maximize savings, set a calendar reminder for December 26th and book your ferry travel for the entire year during this promotional period. The best deals are often available in the first week of the sale, as popular sailing dates can sell out quickly at the reduced rates.

Book Early for France Routes

Irish Ferries offers a dedicated 20% discount on the Dublin-Cherbourg route for travelers who book by September 30th. This early booking discount applies to travel dates between January 1st and October 31st of the following year.

SimplyCodes research confirms this represents the most consistent discount available for French routes throughout the year. Unlike the more variable Irish Sea route promotions, this France route discount follows a predictable annual pattern.

Plan your France travel well in advance and complete your booking before the September 30th deadline to automatically secure the 20% savings. No special promo code is required as the discount is applied automatically during the booking process for eligible dates.

Look for Discounted Foot Passenger Day Trips

Irish Ferries provides special discounted fares for foot passengers on day trips, particularly on Tuesdays and Wednesdays on Irish Sea routes. These "Duty Free Day Trip" specials must be booked at least 24 hours in advance to secure the promotional rate.

SimplyCodes shopping research shows these midweek day trip fares can be up to 40% lower than standard foot passenger fares. The discounted rates are designed to increase passenger traffic on traditionally lower-volume sailing days.

Check the "Special Offers" section of the Irish Ferries website specifically for these day trip promotions when planning short journeys without a vehicle. These deals are particularly valuable for shoppers planning day trips for shopping or tourism.

Lock in Fares with a €300 Deposit

Irish Ferries allows customers to secure their booking with just a €300 deposit when reserving sailings more than 60 days in advance. This deposit option enables travelers to lock in promotional rates during sale periods without paying the full fare immediately.

According to our assessment of Irish Ferries' official policy, the remaining balance isn't due until 60 days before departure. This payment structure provides both financial flexibility and the ability to capture limited-time promotional fares.

When you spot a good sale fare, use the deposit option to secure it, especially if you're booking during the January Sale for travel later in the year. This strategy allows you to benefit from the best promotional rates while spreading out your payment.
