I do. It has to be done at an approved trto for the uk i believe. Another problem is you will lose your A320 rating after 2 years if you dont fly the 320, and will require a full type rating courseat an approved TRTO to recover that rating. Its a minefield now.
I would certainly be getting it in writing from your home country. I may be wrong, but i am not interested anyhow.
You could make yourself unemployable if you are not careful.
