@LemonTootski please bear in mind most of us work full time doing something else, so we can only get round to responding when time allows.
The first thing you must understand is you are not making an appeal, you are only making a representation to Transport for London. Only if your representation is rejected, can you then make an appeal to London Tribunals.
If you're keen on making a representation before you get the video, this will suffice:
Dear Transport for London,
The alleged contravention did not occur because the markings at the location in question do not correctly reflect item 19 of Schedule 2B to The GLA Roads and GLA Side Roads (Lambeth) Red Route Consolidation Traffic Order 2007, furthermore the combination of lines and marking is unauthorised because there appear to be a series of bays which have double red lines running through them, and this layout is not permitted and is liable to cause confusion.
Lastly the PCN does not comply with the requirements imposed by the second part of paragraph 3(1)(a) of Schedule 2 to The Civil Enforcement of Road Traffic Contraventions (Approved Devices, Charging Guidelines and General Provisions) (England) Regulations 2022, and that is a procedural impropriety.
It follows that the penalty charge notice must be cancelled.
Yours faithfully,
