Then pay and you should avoid a big fine. I live 90% of the time in Germany. I paid the 5 anyway and when the PCN arrives will try to appeal it citing that I paid, albeit just after the deadline. Drivers are being charged up to 60% more to use the Dartford Crossing by unofficial websites taking advantage of confusion surrounding the new payment system since toll booths were axed in 2014. Set an identical reminder for your homebound trip using your home postcode7. They are practically inviting fraudsters to target people who may not be the most technically savvy to get scammed., Dont pay at any website other than https://www.gov.uk/pay-dartford-crossing-charge. Please let us know. This can be found on the first page of the penalty charge notice you received in the post, it starts with the letters 'IA', 'IB' or 'IK'. On Wednesday I logged onto the crossing website to make the 5 payment but it was blocked as a dangerous site by the company firewall! I had been charge as a commercial vehicle, the cameras not detecting that my van has a side window which changes the charging rate. Couldnt they have left 1 booth open for all those drivers who dont waste half their life figuring out how to pay ridiculous toll charges in their chosen holiday destination? I did not receive the penalty charge notice. plus let us remember the toll/ charged was to repay to original builders as financed 100% by debt, with no equity contribution. I have today 14/11/2015 received a charge certificate for 105. However, I did not pay in the 14 day period for the bridge crossing as I have been on holiday for 3 and a half weeks. Not received any fine notices since crossing 28th march and 13th April but potentially liable to 140 fine despite being ready to pay.
