Fordley Car Park is open between 7am and 9pm every day. They charge £2.30 per hour with a minimum fee of one hour and a £2 overnight charge for stays between 9pm and 7.30am. Payments are made at the end of a visit. The car park is also used by resident and business permit holders on the basis of annually renewable membership. All new memberships are registered via the Fordley Car Park website or by completing a form which can be picked up from the car park attendant. Recently Fordley has invested in a paperless attended smart parking system that scans car registration numbers as cars drive through the entrance gate. To ensure that a reading has been captured, the gates only open when a valid registration is read. Exit gates also have a camera which scans the car registration number and will open automatically unless payments are outstanding in which case the payment can be made at the attendant kiosk without leaving the car. Members whose membership has expired can also pay for the…
