Mick,
I checked out the current transitional arrangements and can confirm that Monera will most likely need to take a new test.
The cut-off date for other tests being for applications submitted before 6 November 2015
Here's a link to the current and latest UKVI approved listing - Approved Secure English Language Tests and Test Centres
Just double check the list to see if she's lucky.
Anyway Mick, I'd suggest going for a test at B1 level as this will be needed for subsequent ILR and Naturalisation applications.
