Hoping someone can help..on Sunday we drove into London we drove into the congestion zone around 11.30 we then parked our car up which was still in the congestion zone and didnt leave london until 8pm..so the congestion charge website states on Saturdays Sundays and Bank Holidays congestion zone is 12pm to 6pm.. so do we have to pay as we drove into congestion zone before the time and left after the time? But our car was parked up in the congestion zone so do we still need to pay?
