Chartered accounting qualifications like ACA, ACCA, CIMA already are Level 7 (Masters degree) equivalent. They all also offer a route into Masters ( usually in Accounting) that will take your completed exams into account.
I have a friend who got ACCA qualification, and only needed to write a dissertation to get a Masters in Accounting in addition to ACCA: all her ACCA coursework/exams were enough to exempt her from all Masters programme courses.
As the other poster said, check the ACA professional body website, and they give you options for various Masters programmes. They will be particular courses in particular unis that have an agreement with ACA programme.
Only if you want a Masters in a different subject or a different uni, you need to revisit your A levels etc.
