I parked my bike between the O and the N of "Only" so nearby the right edge of the bay. I did this exact thing the last time they suspended the parking in the same bay and didn't get fined that time. And it was two weeks ago.
So again using GSV distance measurement, you were about 2.7 metres from the north end of the bay, and also directly opposite the door of the Japan Centre. However the bay is not subdivided so if they want to suspend parking in part of it they have to be precise and for me, the suspension sign is ridiculous on its own, they should have place something to physically mark the boundaries of the suspended area.
So I suggest you submit an informal challenge on the following lines: -
Westminster City Council
Parking Department
Dear Sirs
Re PCN <PCN Number> dated <dd/mm/yyyy) served at <time> at <location>
I deny liability for the above PCN penalty on the grounds that the contravention did not occur. I read the suspension sign, but it does not give accurate information on which part of the bay is suspended. The sign states that 5 metres, (one space) is suspended. However, the bay is just under 12 metres long, with no subdivisions therefore it is impossible to work out which part is suspended in the absence of any physical measure like traffic cones.
In view of the defective information on the suspension sign, I request that the PCN be cancelled.
Yours faithfully
Don't expect them to roll over and cancel, because all they are interested in is your money. You have to be prepared to take them to London Tribunals, where, IMHO, you would have a strong case However, see what the others say before submitting reps, but don't miss the deadline for submitting them.
