Sutton Council has revealed it raised car parking charges for people using machines in June.
But for those who use an app or automated telephone line, the charges have been frozen.
This has caused an upset from some drivers who say they don’t have access to apps.
The authority says it wants all residents and visitors to go cashless when paying for parking with the incentive being a discounted rate.
A spokesman goes on to say “maintaining the parking machines and collecting the money from car parks has become more expensive.”
