Fully agree with Ugly Duckling, far too waffly, contentious and dilutes the main point.
Dear Sirs
Ref PCN

??
The vehicle was charging.
This can be seen from the CEO photos which clearly show the green charging light on the charger
As such the alleged contravention did not occur and the PCN must be cancelled.
I look forward to your Notice of Acceptance
Hugs and Kisses
That is all that is needed.
You can add in a comment on that they sought to continue to enforce on another contravention within the informal rejection, a step that is not allowed within the regulations and therefore a Procedural Impropriety, could even throw in that ignoring the main point is a failure to consider.
But these weaken the main point and can be added to better effect if the council reject with the same reasons.
As an aside, it seems that they are seeking to use the underlying contravention in similar ways that some try with time arguments in Disabled Bays, totally ignoring that they could and should have applied a Parked over Permitted Time PCN
