Using child ticket as adult

Short answer

No. A mature or older university student cannot lawfully travel on a child ticket. Child fares on National Rail are age-based, not status-based. Being a student, however mature, gives no entitlement to a child fare. A child ticket is only valid for children within the defined age range, and using one when you are outside that range means you do not hold a valid ticket for your journey and you risk a penalty fare or prosecution.

The age rule, not a student rule

On National Rail the child fare applies to children broadly aged 5 to 15. Once a person reaches 16 they must buy an adult ticket, regardless of whether they are still at school, in further education, or a full-time university student. Age, not educational status, determines the fare category. Chiltern Railways, for example, states plainly that anyone aged 16 or over must travel on an adult fare, and this reflects the general position across operators. There is no exception that allows an adult student to buy a child ticket simply because they are studying.

The confusion sometimes arises because there are separate concessions for students and young people, but these are entirely different products. A 16 to 25 Railcard (also available to mature students aged 26 and over who are in full-time education) gives a discount on adult fares. It does not entitle the holder to buy a child ticket. Local bus operators and Transport for London have their own age-based child and young person concessions with their own rules, but the same principle applies: eligibility depends on age and on holding the correct photocard or pass, not on being a student in a general sense.

Why using a child ticket is unlawful for an adult

If you are 16 or over and travel on a child ticket, you are not holding a valid ticket for your journey. Under the National Rail Conditions of Travel and the Railway Byelaws, you are required to have a valid ticket entitling you to travel. A child ticket held by an adult does not provide that entitlement, so you are travelling without a valid ticket even though you have paid something.

There is a further and more serious dimension where deliberate deception is involved. Buying a child ticket in the knowledge that you are an adult, in order to pay less than the correct fare, can amount to a fare evasion offence. Depending on the circumstances and the operator, this can be dealt with as a Byelaw offence or, more seriously, under the Regulation of Railways Act 1889, which covers travelling or attempting to travel without paying the correct fare with intent to avoid payment. The Railway Byelaws also make it an offence to buy a ticket on behalf of another person intending to enable them to travel without paying the correct fare, which is relevant if, for instance, someone buys child tickets for an adult.

What can happen in practice

If you are found travelling on a child ticket when you should hold an adult ticket, the likely consequences are:

1. A penalty fare. On many services this is currently £100 plus the price of the full single fare for your intended journey, reduced if paid promptly. A penalty fare is an administrative charge, not a criminal conviction.

2. Being reported for prosecution. Where the operator considers there was intent to avoid the fare, it may prosecute rather than issue a penalty fare. A conviction, even under the Byelaws, results in a fine and a criminal record entry, and Regulation of Railways Act 1889 offences involving intent are treated more seriously and can affect future employment and travel.

3. Being asked to pay the correct adult fare in any event, in addition to any penalty.

The distinction between an innocent mistake and deliberate evasion matters. If a genuine error occurred, for example a ticket machine or app misused, or a young-looking adult who honestly misunderstood the rules, that points towards a penalty fare and payment of the correct fare rather than prosecution. If the pattern shows deliberate use of child tickets to save money, the risk of prosecution for an intent-based offence is much higher.

The lawful alternatives for a mature student

If the aim is to travel more cheaply, there are legitimate options rather than misusing a child ticket:

A 16 to 25 Railcard is available to anyone aged 16 to 25, and also to mature students aged 26 or over who are enrolled in full-time education, subject to the current eligibility conditions and providing the required proof. It gives roughly a third off most adult fares.

A 26 to 30 Railcard is available on an age basis to those in that bracket.

Student-specific travel concessions from your university, students’ union, or local transport operator may also exist, and these are the proper route to a student discount.

Advance tickets, off-peak travel, season tickets and split ticketing are all lawful ways to reduce cost.

Practical next steps

If you have simply been using a child ticket and want to correct your position, stop doing so and buy the correct adult fare, obtaining a railcard if you qualify. If you have already been stopped and issued a penalty fare, check whether it was correctly issued and note the operator’s appeals process and time limit, which is usually set out on the penalty fare notice. If you have received a letter saying the operator is considering prosecution, respond carefully and promptly, because a well-evidenced explanation of an honest mistake and an offer to pay the correct fare can sometimes lead the operator to accept an out-of-court settlement rather than proceeding to court.

Bottom line

Being a mature student does not entitle you to travel on a child ticket. Child fares depend on age, and anyone aged 16 or over must travel on an adult fare. Using a child ticket as an adult means travelling without a valid ticket and, if deliberate, can amount to a fare evasion offence carrying a penalty fare or prosecution. The correct way to save money as a student is a railcard or other legitimate discount.
