How to book cheap train tickets from Cardiff to London

Season Tickets for frequent travel

Are you frequently traveling between Cardiff and London on a weekly, monthly, or annual basis? Season Tickets provide unlimited travel during specific times, allowing you to freely hop on and off trains between two stations without worrying about individual ticket bookings, and offering significant savings in the process.

Network Railcard for South East England

By purchasing a Network Railcard for only £30 per year, unlock incredible savings of up to 1/3 on every ticket for your travels within London and the South East. With this Railcard in hand, you can enjoy reduced costs on various ticket types, including Standard or Super Off-Peak Tickets.

Traveling in off-peak train times

Taking advantage of Off-Peak train tickets is another effective way to save on your train journey from Cardiff to London. These tickets are generally cheaper and can be used during quieter periods, typically outside of morning (6:30 AM–9:30 AM) and evening (4:00 PM–7:00 PM) rush hours on weekdays.

Get 1/3 off with a Railcard

Railcards offer discounts of up to 1/3 on most tickets. There are various types of Railcards catering to different types of travelers, such as the 16–25 Railcard, the Family & Friends Railcard, and the Senior Railcard.

Split tickets to save an average extra 30%

Another option to consider is splitting your tickets, which can save you around an extra 30% on fares. Instead of purchasing a direct ticket from Cardiff to London, you can split the route into two legs: A to C and C to B. This often turns out to be more affordable than buying a direct ticket, and you won't even need to leave the train… or often your seat!

Book in advance to save an average of 61%

Did you know that purchasing Advance Tickets can significantly reduce your travel expenses? On average, these tickets can save you an impressive 61% on fares. The best part is that the earlier you book (ideally up to 12 weeks in advance), the greater the savings!

Travel in a group to save 1/3
