Converting my ICAO frozen ATPL to UK EASA ATPL unrestricted

[Captainsami]

Dear All,

I would like to ask about what it takes to convert my non-UK ICAO frozen ATPL to UK EASA ATPL unrestricted.

I've been through the UK CAA website but it needs an attorney to understand the hidden lines.

I've a total flying time of 1230 hrs on powered-fixed wings aircrafts "including" 1012 hrs on A-320 and I hold ICAO frozen ATPL.

Now, I can see the requirements are 1500 "total" flying hrs.

I need a ground school/distance learning from an ATO to be able to apply for the theoretical exams but I heard that that ground school can be waived if I've 1500 hrs but the question is: Is it a must to have all the 1500 hrs on a Multi-crew aircraft or just a total flying time?

Thanks
