I wonder can you just mark it yourself as seems to be suggested below.

Of course you can as long as the marking isn't fraudulent. You'd have to be able to justify it, if asked.
Be careful if you are claiming pre-2016 rights for your EAPC. The rules for marking earlier bikes were different, todays rules on the plate will tend to indicate your EAPC is very recent:

Clarification from the above link on the specification plate required on pedelecs
Plate (a) (i) is only for the historic e-bikes from before 6th April 2015.
Plate (a) (ii) is for all pedelecs since that date.
Confirmed as below by James Brown, International Vehicle Standards, Department for Transport:
"As part of the GB EAPC amending legislation, that will come into force on 6 April 2015, the requirement for the marking identification has been amended. Previously a plate showing the manufacturer, maximum continuous rated power output and voltage was necessary, from April 6 2015 the requirement will be that the manufacturer, maximum continuous rated output and maximum assisted cutoff speed shall be marked on the cycle."
This should be in the form of a plate or permanent label bearing all three items of information, mounted in a prominent easily read location on the bicycle.
