AFAIK, in the UK the penalty charge notice must be attached to the vehicle
or handed to the driver.

Correct, assuming that the OP is referring to a local authority parking attendant
rather than a traffic warden.

There are also certain circumstances (covered in later legislation) where they
can send the PCN through the post to the keeper, and some of this legislation
applies in London only, and curiously not in all boroughs.

In this case, it would seem that the PCN wasn't correctly served, and no penalty
charge is due. However, if the PA's notebook records that he did attach the
PCN to the car, Camden are unlikely to cancel it and you will have to convince
the Adjudicator that your version of events is the correct one. You won't be able
to find out what the PA's notebook says until you appeal.
