Contravention 12A Binfield Road

I received a PCN at an EV charging point on Binfield Road contravention code 12A. Due to the heavy rain that night I didn’t realise it was a permit only zone (my permit had lapsed)

Received a generic response from Lambeth on the subject.

Wondering whether there’s any chance of winning if I take it further or whether I should just bite the bullet for the £65
