As someone in the same situation, speaking with CAA PLD, you need to have the skills test passed, and the application form into the before them 30th June.
The IMC is valid for 25 months from date of test.
I'm not taking any chances, and will try and get the course, exam and test completed in early May and get it off to them with 6 weeks to spare (so I can hopefully have it in hand by the 30th June).
After the 30th June you can add it to a CAA national licence, but not an EASA one.
