You do hold a PPL, at least, don't you? Weren't you taught in PPL ground class what requirements you must meet for international flight? If not, I suggest you sue your training organisation!
That said, following certain recent events there are exceptions in effect at certain FR aerodromes, but
AFAIK there's no difference for UK <=> LFAT flights (or, for that matter, UK <=> LFAC or other French "fields of entry"). Given the present instability, I would still recommend getting in touch with your destination field before take-off. A little phone call could bring a lot of relax.
