Hi Neil the guidance we issue currently states:
"Our position is to recommend time-based fees, applied after the
maximum charge session time each host permits. A solution that we
would consider as the optimum starting point would be to charge £1
per minute overstay, with a ten-minute grace period. Anyone ending
charging within the period would not be charged, but as soon as the
overstay exceeds that ten-minute window, the minimum overstay fee
would be £10. The fees would be collected as part of the standard
transaction through the ChargePlace Scotland management system.
Each host would need to define the maximum charge session length
for themselves. Our guidance is summarised in Table 1.
The ideal would be for overstay fees to be universal across all hosts.
Recognising that it would however be problematic to allow the total to
increment indefinitely, we proposed the upper limit that can be applied
to any single infringement be set at whatever the local Penalty Charge
Notice standard rate is. This would hopefully be appropriate to ensure
that the cost of appeals and their administration is kept to a minimum."
This has been implemented in ELC and other LA's and has been very effective, where appropriate notices are posted. Complaints to the LAs or to us are about 3 in over two years. The key aspects are the ten-minute grace period and the upper limit for the progressive fee. We haven't discriminated between Journey and Destination chargers, although the position is needing to be reviewed. The object is not to generate revenue from overstay, but to ensure maximum availability and energy delivered revenue for the owners. Feel free to comment here or DM on the guidance doc
