A guide to child train tickets in the UK: What parents need to know

Here’s a super quick breakdown of how UK rail defines ‘child’ passengers:

Children under 5: Travel free

Children under 5 years old travel for free on UK trains when accompanied by a fare-paying adult. You don’t need to book a ticket for them, but it’s pretty crucial to note:

• They won’t be guaranteed a seat - if the train is full, they may have to sit on your lap.
• If you want to reserve a seat for your child under 5, you’ll need to pay for a child fare.

Children aged 5-15: Child fares apply

Children aged 5 to 15 are eligible for discounted tickets, typically priced at 50% of the adult fare. This applies to:

• Advance tickets
• Off-Peak & Anytime tickets
• Railcard-discounted tickets (when applicable)

Usually, no ID is required when buying or using child tickets. However:

• If your child looks older than 15, train staff may ask for proof of age
• It’s helpful to carry a passport or student ID if your child is tall for their age

Some ticket inspectors can issue penalty fares if they believe a child ticket is being misused.
