From what I have gathered- In theory, Cambridge funding results start getting out after the last application deadline which is March 3. But in reality most begin to send out decisions in late March-early April. The entire process runs till June thereabouts, because some candidates that were awarded in the early phase may decline due to going elsewhere, or multiple awards (cos most funding bodies operate independently, but in the end nobody gets more than one full funding as the Trust coordinates everything).
So generally I’ll say from mid-March onwards.
Goodluck to us all.
