Train tickets from London to Portsmouth start at £8§ one way for a Standard Class ticket if you book in advance. UK train companies usually release Advance tickets up to 12 weeks ahead of time, and these can be cheaper than tickets bought on the day of travel.

3. Use a Railcard
National Railcards offer a 1/3 off eligible train tickets in the UK and can be a great investment if you travel throughout the year. Buy one with us and you'll be able to store it digitally in our app, so you'll always have it on your travels.
4. Book split tickets
Our handy feature SplitSave will 'split' your train journey into multiple tickets, which can be much cheaper than buying a single ticket. Find out more about split tickets.
5. Travel Off-Peak
If you can be flexible with your travel times, Off-Peak and Super Off-Peak tickets are usually cheaper in the UK. Generally, Off-Peak times are any time at weekends and outside of Monday to Friday morning and evening rush hours.
6. Consider a Season Ticket
Best for commuters, if you catch a train on the same route more than 3 times per week, you could save money with a Season Ticket. With annual, monthly, weekly and flexi options available, find out if a Season Ticket for London to Portsmouth is right for you.
