Reply disputing the points not covered in their response.
Specifically the non PoFA compliance.
Also challenge their evidence regarding the disabled bay markings (if that's what they are) as they are simply applied OVER the already applied bay markings and are in a state of total dis-repair.
You do not need to pay anything and the chances of this going to hearing a very small - even if it did, you would easily defend it.
Put some comments together and post it up for further guidance.
Nothing to worry about.
Just re-examined the pictures and the bay markings are clearly visible for your bay - this needs to be specifically drawn to the assessors attention.
Also, when I checked on GSV (when you first posted), I am sure that you could use GSV to demonstrate that the 'cross hatch' had been added retrospectively - meaning that the original bay markings would already have been present?
