I don't find emails very effective. Give them a call at LGW and have a chat with someone in FCL, they are usually quite helpful.
I guess you are operating on a validation supported by your UK license.
UK CAA didn't adopt JAA for FEs as they thought we would all be dead by now.
My UK FE license expires next month but I'm not renewing it as I now have an Irish issued JAA one for the A300.
Good luck.
