Frequently Asked Questions about The Tube

Welcome to our London Underground Frequently Asked Questions section. Here you will find clear answers to the most common questions about using the London Underground, Oyster cards, contactless payments, incorrect charges, refunds, receipts and other issues that may occur during a trip to London.

Many questions are related to unexpected bank card charges, duplicate payments, maximum fares, incomplete journeys or problems when paying with a mobile phone or smartwatch. In these situations, the most important thing is to review your journey history through the official Transport for London account system and, if necessary, request a refund directly through TfL.

Important: this page is for informational purposes only and is not affiliated with Transport for London. If you need to modify a charge, request a refund or check payment details, you should always use the official TfL website or your Contactless/Oyster account.

Why Have I Been Overcharged on the London Underground?

If you used the London Underground with a contactless bank card, Oyster card, Apple Pay, Google Pay or another payment method and notice a higher charge than expected, there may be several explanations. The most common reason is that TfL could not correctly reconstruct your journey because an entry or exit touch was missing.

This may happen if:

• You forgot to touch in or touch out.
• The card reader did not correctly register your card.
• You used one card to enter and a different card or device to exit.
• You entered using a physical bank card and exited using your phone or smartwatch.
• You tapped on the wrong reader, especially at airports or National Rail stations.
• There was a gate or validation system failure.
• The system registered an incomplete journey.

When this happens, TfL may apply a maximum fare. In many situations, the system automatically corrects the charge later, but if it does not, you can usually request a refund through your TfL Contactless and Oyster account.

What Is a Maximum Fare on the London Underground?

A maximum fare is a higher charge applied when TfL cannot determine exactly where your journey started or ended. The system needs both an entry and an exit touch in order to calculate the correct fare. If one of these is missing, TfL may assume the journey was incomplete and charge more than the normal fare.

This does not always mean you made a mistake. Sometimes it happens because of faulty readers, access gate problems, complex stations with several transport systems or using different payment devices during the journey.

If you believe you were incorrectly charged a maximum fare, wait at least 48 hours, review your journey history and request a refund if the charge has not been corrected automatically.

What Is an Incomplete Journey?

An incomplete journey happens when TfL only records part of your trip, such as an entry without an exit or an exit without an entry. In these situations, the system cannot calculate the correct fare.

This is one of the most common reasons why passengers see unexpected charges of £11, £12, £15, £16, £19 or more. It may also prevent the correct application of the daily fare cap.

To resolve the issue, log into your TfL Contactless and Oyster account, review your journey history and use the refund option for incomplete journeys if necessary.

What Should I Do If TfL Charged Me £15, £16, £19 or More in One Day?

If you see charges such as £15, £16 or £19 after using London public transport, first check whether you travelled to airports, National Rail services, the Elizabeth line or zones with higher fares.

If you only travelled within central London and the charge seems excessive, it is likely related to a maximum fare, incomplete journey, validation error or pending payment adjustment.

Recommended steps:

1. Wait 48 hours to see if the charge is automatically corrected.
2. Log into your Contactless and Oyster account.
3. Check your journey and payment history.
4. Look for incomplete journeys.
5. Request a refund if necessary.
6. If the issue cannot be solved online, contact TfL through the official help channels.

Never send your full bank card number by email. In most cases, TfL only requires partial card information such as the last four digits.

How Can I Claim a Refund for an Incorrect London Underground Charge?

The best way to claim a refund is usually through the official TfL Contactless and Oyster system. The process depends on whether you paid using a bank card, Oyster card, mobile device or another registered payment method.

1. Log into the official TfL Contactless and Oyster website.
2. Create an account or sign in.
3. Add the card or payment method used for travel.
4. Review your journey history.
5. Locate the incorrect charge or incomplete journey.
6. Use the refund option available.
7. If the issue cannot be resolved online, contact TfL through their official support form.

TfL generally recommends waiting at least 48 hours before requesting some refunds, as certain charges may be corrected automatically by the system.

Why Was I Charged Twice on the Same Day?

Seeing two charges on the same day does not always mean you were charged twice incorrectly. London transport payments may group several journeys together, process delayed adjustments or separate charges if multiple cards or devices were used.

This may happen if:

• One charge corresponds to normal travel.
• Another charge corresponds to a maximum fare.
• One amount is a temporary bank pre-authorisation.
• You used both your physical card and your phone or smartwatch.
• TfL retried a previous failed payment.

The safest way to verify this is to check the journey history within your TfL account.

What Happens If My Bank Blocks a TfL Payment?

If your bank blocks a TfL payment, for example because international payments were disabled or the card was declined, TfL may retry the payment later. While the balance remains unpaid, your card may stop working for London transport.

In these situations:

1. Resolve the issue with your bank.
2. Log into your TfL account.
3. Check for pending payments.
4. Pay any outstanding balance through official TfL channels.
5. Avoid using the same card until the issue is resolved.

If you receive a pending payment notification, always make sure you are using the official TfL website before entering payment details.

Why Did TfL Charge Me Days or Months After My Trip?

Some TfL charges may appear days or even months later due to pending payments, delayed bank processing, system adjustments or previous payment failures.

If you receive a late charge, review:

• The exact charge date.
• The payment description shown by your bank.
• Whether you used that card in London.
• Whether a previous payment may have failed.
• Whether the charge appears in your TfL account.

If you do not recognise the payment, contact both TfL and your bank.

What Happens If I Accidentally Used My Bank Card Instead of a Ticket I Already Bought?

This is relatively common at airports and stations where Underground, National Rail and airport services share the same gates or readers. If you already had a valid paper or digital ticket but accidentally tapped your bank card, TfL may register a separate journey and generate an additional charge.

To try to resolve the issue:

1. Keep your original ticket.
2. Save the booking confirmation or receipt.
3. Check the charge in your TfL account.
4. Request a refund explaining the mistake.
5. Provide supporting evidence if requested.

Refunds are not guaranteed, but if you can prove you already had a valid ticket, it is worth contacting TfL.

Does the Daily Fare Cap Always Apply?

The daily cap helps limit the total amount paid each day when using pay as you go travel. However, it only works correctly if you consistently use the same payment method throughout the day.

The daily cap may fail to apply correctly if:

• You use different cards or devices.
• You mix physical cards with Apple Pay or Google Pay.
• Several people use the same card.
• There are incomplete journeys.
• You travel on special airport or rail services.

For this reason, it is important to always use the same payment method for all journeys.

Can I Pay for Multiple People with the Same Card on the London Underground?

No. Each adult passenger must use their own Oyster card, contactless card or mobile payment device. The same card cannot normally be used to pay for several adults travelling together.

If multiple passengers try to use the same card, this may create incomplete journeys, incorrect charges or validation problems.

How Can I Get Receipts for London Underground Journeys?

If you need travel receipts for business expenses or accounting purposes, you can obtain them through a TfL Contactless and Oyster account.

Typical steps include:

1. Create a TfL Contactless and Oyster account.
2. Add the card or payment method used.
3. Access your journey and payment history.
4. Download or review the journeys you need.

If you did not create an account before travelling, you may still be able to register the card later and recover some journey history.

Should I Send My Full Bank Card Number When Claiming a Refund?

No. It is not recommended to send full bank card details by email or through insecure forms. TfL usually only needs limited information such as the last four digits of the card, travel dates and payment amounts.

Always use official TfL channels when entering payment details.

How Long Does TfL Take to Refund Incorrect Charges?

The refund timeframe depends on the issue. Some charges are corrected automatically within hours or days. TfL usually recommends waiting at least 48 hours before claiming refunds for incomplete journeys.

After the refund is approved, the time required for the money to appear in your account also depends on your bank.

Where Can I Contact TfL About Payment Problems?

For payment issues, refunds, incomplete journeys or pending balances, the safest option is to start through the official TfL Contactless and Oyster system.

You can also use TfL’s official help and contact pages. Always verify that you are using official TfL domains before entering any banking information.

Which Transport Card Is Best If I Travel with a Child Under 11 in London?

Children under 11 can normally travel free on the London Underground, buses and many other TfL services when accompanied by a paying adult.

Adults should use their own Oyster or contactless payment method, while children can pass through the wider gates with the accompanying adult.

For older children travelling alone, TfL offers Zip Oyster photocard options with discounted fares.

Are There London Underground Discounts for Non-Resident Seniors Over 60?

Most free or discounted travel schemes for people over 60 are intended for London residents who meet specific eligibility requirements. Non-resident visitors generally cannot access the same free travel benefits.

However, visitors may still save money by travelling off-peak, using Oyster or contactless correctly and avoiding incomplete journeys or maximum fares.

Can I Travel with an Assistance Animal on the London Underground?

Yes. TfL allows properly trained assistance animals, including guide dogs, on London public transport.

If you need to travel with a non-standard assistance animal or have special accessibility requirements, it is advisable to contact TfL in advance.

Can You Visit Abandoned or Historic Parts of the London Underground?

Yes. Several guided experiences allow visitors to explore abandoned stations, historical tunnels and hidden parts of the London Underground. One of the best known options is the Hidden London tour programme organised by the London Transport Museum.

Popular tours include Aldwych station, Down Street station, Clapham South deep-level shelter and other historical Underground locations.

The Postal Museum also offers the Mail Rail experience through former underground postal tunnels.

Most tours require advance booking and may have accessibility or age restrictions.
