Heading on holiday can be both exciting and stressful in equal measure, making it easy to forget banal chores such as paying for your trip over or under the Thames Here are some suggestions to help ensure you dont come home to a big fine. We the coin. It really is a poor situation, but you will have to go through the whole process just to prove you didnt do anything wrong. I havent received a PCN and am worried that I will now have missed the 14 day deadline (albeit without receiving a PCN) and will be charged 70, possibly for each journey. Unofficial siteswill simply take your money, pocket the admin charge and pay the outstanding toll on the public Dart Charge site regardless of vehicle details. Make sure you keep a record of making the payment. My family went over dartford crossing in August on holiday no signs saying when or how to pay didnt even know you had to wasnt till we visited fiends a few days later that we found out went online and paid for both journeys payment was accepted now 4 months later been sent a PCN for 14:50,really annoyed after theyd taken my payment.Mine is a lease car so fine sent to lease company they paid the fine,then took it from my wages, now Ive got to try and claim it back. HI I forgot to pay on the 21/12/2014 when the new system started I was later contacted by dart and offered the opportunity to pay which I did for both journeys/directions. Hi. Today we received another letter demanding 215 stating that the 2 PCNs remain unpaid! Christmas night Ive crossed dartford and forgot to pay the charge. There is a further difficulty.
