gmaa - Astraeus already have approval to conduct A320 type-ratings, i.e. the infrastrucure required already exists and has, accordingly, been approved by the UK CAA; and, furthermore, some pilots have already partaken of said such A320 type-rating.
Nb.
Click here to a link that shows the UK CAA's list of approved TRTO's and their Type Rating training acreditations ( Astraeus' approvals can be found on page 21 of that document ). The CAA will not grant TRTO status unless a company is able to demonstrate that it can conduct its courses to the satisfaction and standards expected by the regulator - needless to say, there's an awful lot more to getting, and keeping, a TRTO Approval than might be understood by the layman or student.
That said, the option for 'line training' aboard Astraeus' Airbus aircraft is not available as yet
..... now there's a 'rumour' !
