In practice:
Copy of Part-FCL Examiners Approval Certificate
Not required if it was an examiner from the same state of licence issue. I.e UK examiner and UK issued CPL.
Certified copy of passport (only by head of ATO)
Not required if you all ready hold a PPL issued by the same country if not then yes - or the original must be sent.
Certified copy of Certificate of Revalidation (only by head of ATO)
Not required if previous state of issue is the same as new state of issue.
Section 8 has to be filled out and signed off by HoT at the ATO conducting the Theoretical Training so I also have to go to BGS!!
Yes is required.
Final question - my Class 1 Med has expired though I have no intention of using the CPL immediately - can it be issued with only a Class 2? Thanks.
Your class 1 must be valid at time of licence issue - so you'll need to renew for the application to be accepted.
You need to read :
IN-2012/206: Important Information regarding licence applications | Publications | About the CAA as well as now if the licence is rejected then they return it to you, and then you have to resubmit it from scratch.
My recommendation is to get as many signatures as possible it won't take more than 1-2 emails - may as well get the ATO to certify the revalidation pages - any good ATO (FTO) will oblige.
I've had to re-sign the new new 1183 many times since the introduction of EASA.
Congratulations on the CPL!
Good luck with the job hunt.
