Driving in London will cost 30% more from next month, under the terms of the Government's £1.6 billion bailout of Transport for London.
With passenger fares falling by 90% as Londoners stayed home and tourists stayed away during the coronavirus lockdown, TfL was forced to go to the Government for a bailout to keep running.
But the terms of the deal mean anyone driving to - or through - London will see their costs rise.
The congestion charge will rise from £11.50 a day to £15 from 22 June, City Hall said. It will also operate from 7am to 10pm, seven days a week, instead of just weekdays.
Mayor Sadiq Khan accused the Department for Transport (DfT) of "making ordinary Londoners pay the cost for doing the right thing on Covid-19".

The congestion charge was waived during lockdown with the majority of people living in or around London working only travelling for essential reasons.
But the £11.50 charge will return on Monday 18 May, along with the ultra low emission zone which costs £12.50 for most vehicles and £100 for heavy lorries or coaches.
TfL said it will extend the congestion charge reimbursement scheme for NHS and care home workers temporarily.

The bailout consists of a £1.1 billion grant and a £505 million loan.
Khan said it was "not the deal I wanted but it was the only deal the Government put on the table".
He went on: "I had no choice but to accept it to keep the Tubes and buses running.
"Fares income has fallen by 90% in the last two months because Londoners have done the right thing and stayed at home - so there simply isn't enough money coming in to pay for our services."
As well as increasing the congestion charge, TfL has been told to introduce above-inflation fare rises from next year. Fares will go up by RPI+1%.
Fares on buses - scrapped to help protect drivers from Covid-19 - will be reintroduced, free travel for children will be stopped temporarily and only people over 60 or with a disability will be allowed to travel for free outside peak hours.
The DfT said the agreement means TfL will increase service levels "as soon as possible to ensure people can follow social distancing guidelines while on the network".
The department said it included a series of caveats as part of the funding package "in order to safeguard services in the future".
A London Covid-19 Task Force - featuring representatives from the Government and TfL - has been established to oversee operational decisions during the pandemic.
Transport Secretary Grant Shapps said services must be increased to "support social distancing and ensure our capital keeps moving".
He went on: "This deal will encourage a real move towards greener and healthier walking and cycling options, ease pressure on our public transport and provide certainty and stability for London's transport services in the future."
