The easiest and cheapest way to get around London is by using an Oyster Card.
You can purchase an Oyster Card at any station or you can order one online to be delivered to you (purchase and delivery charges apply). Before you return home, you can hand it back in to reclaim your deposit. Oyster Cards work on a 'pay as you go' basis, but you may also purchase a daily, weekly or monthly travel plan.
If you travel more frequently and across different zones, it may be worth getting a Student Oyster Card which gives you discounts on your travel. Before applying for your 18+ Oyster photo card, ensure that this will be the cheapest option for you, and check the eligibility criteria carefully. For example, you must be enrolled on a full-time course made up of at least 15 tuition-led and/or structured learning hours a week (with attendance at scheduled classes being Monday to Friday only and not including evening classes) over a minimum of 14 weeks on the same course.
