Transport for London (TfL) is reminding people to take extra care when paying the London Congestion Charge online and to make sure they are using the official website - tfl.gov.uk/cclondon

TfL is aware that a number of websites offer to pay the Congestion Charge on behalf of drivers.  However these websites are not official payment channels and they charge motorists a premium, in some cases as much as £6.
 
Unofficial sites pay search engines to promote their businesses and ensure they are the top items when people use terms like 'Pay Congestion Charge'. Around 1,000 people a day are, in many cases, unwittingly using unofficial sites to pay the Congestion Charge. The unofficial websites justify their inflated prices by claiming they offer extra services for customers such as email confirmation and a dedicated phone helpline. However TfL offers these services free of charge.
 
There have also been a number of cases where these unofficial sites have failed to pay the Congestion Charge on behalf of their customers, resulting in drivers receiving a Penalty Charge Notice (PCN) from TfL for non-payment.
 
Garrett Emmerson, TfL's Chief Operating Officer for Surface Transport, said, “We urge customers paying the Congestion Charge online to be careful and to double check that they are paying via the official TfL website which is a quick and easy way to pay, and avoids any unnecessary charges." 
 
'We are doing as much as we can to minimise the risk of unofficial websites or adverts misleading customers into paying more than they need to, including talking to Trading Standards, the Office of Fair Trading, the Advertising Standards Authority and search engine providers. We will continue to pursue these avenues but in the meantime we urge motorists to take care and only use TfL's website.”
