Try Flight Training News - they get a fair bit of info from the CAA and publish a summary every few months.
If that doesn't do the job, and you have a genuine safety research purpose, then I'd suggest contacting the CAA and asking nicely. They will certainly have this information because it's in everybody's periodic medical forms.
