Slightly off topic, but for info, the SFI is a company authorisation issued by the national authority. It isn't a rating that follows you if you leave the company. Once you leave, you no longer have the SFI. The TRI is a rating endorsed on the ratings page of the licence, and valid for 3 years like the TRE authorisation, that stays in the licence even if you leave the company who you were a TRI for.
