Under new rules implemented by Mastercard, Visa and American Express, we must now request authorisation from your card issuer for up to £120.00. Once you've finished filling up, the final transaction amount is sent to your card issuer, and the remainder of any unused funds up to the maximum filling amount will be released back to your available balance. We'll only ever charge you for the value of the fuel you've actually purchased. If you have a problem with a payment, please contact the bank that issued your card.
