If you plan to come by car there are a number of car parks within the Park, all Pay and Display.
Wandsworth Council raise the fees regularly, so check the Wandsworth Borough Council website (search for “battersea park parking charges”)
Disabled Badge holders should check at the signs in the Car Parks but generally the rules when a valid badge and clock card are displayed are 3 hours during weekdays and no limit at weekends.
Local streets are almost exclusively permit holder only or pay and display, although almost all are free at the weekend. Again, check the signs for the latest.
Wandsworth Council are removing many of the Pay and Display ticket dispensers in the surrounding area; their logic is that most people can now pay using their mobile phone.
Overnight parking within the Park car parks is not authorised.
