How to book cheap train tickets from Cardiff to London Kings Cross

Season Tickets for frequent travels

For frequent travellers between Cardiff and London Kings Cross, consider a Season Ticket, providing unlimited travel between specified stations for different durations, such as weekly, monthly, annually, or flexi. Alongside substantial savings, enjoy the convenience of not having to buy a ticket for each journey.

Network Railcard for Southeast England

For only a small annual fee, you can save 1/3 on most fares in Southeast England, including routes in and out of London, with the Network Railcard. Covering both standard and off-peak tickets, this railcard is particularly beneficial for those who travel regularly within this region.

Travelling in off-peak train times

We recommend buying train tickets from Cardiff to London Kings Cross during off-peak hours. These times are usually before 06:30, between 09:30 and 16:00, and after 19:00 on weekdays, as well as all day on weekends and bank holidays. Choosing Off-Peak train tickets means benefiting from cheaper fares and less crowded trains, making your journey more enjoyable.

Using the Railcard for 1/3 off

You can choose a Railcard to help you save up to 1/3 on fares from Cardiff to London Kings Cross for various reasons, such as your age (including the 16-25 Railcard or Senior Railcard) or options geared towards group travel (Family & Friends Railcard and Two Together Railcard). Discover more here.

Split Tickets to save an average extra 30%

Splitting tickets is a perfectly legal practice that involves purchasing separate, cheaper tickets for different segments of your journey on the same train instead of a single ticket for the entire trip. For example, if you are travelling from Cardiff to London Kings Cross, you might discover that buying a ticket from A to C, and then another ticket from C to B, is more economical than a direct ticket.

Book in advance to save an average of 61%

Advance Tickets are typically released up to 12 weeks before the travel date and can offer significant savings compared to tickets purchased closer to departure. By planning your trip from Cardiff to London Kings Cross ahead of time and booking your tickets early, you can potentially save up to 61% on your travel expenses.

Group travels to save 1/3

If you are planning a trip with a group of three to nine people, take advantage of ⅓ off standard fares with group travel discounts, offered by many train companies, perfect for journeys with your family, friends, or colleagues.
