How early should I apply for a postgraduate course in the UK? 

It's recommended to apply for a postgraduate course in the UK as early as possible to increase your chances of being accepted and to give yourself enough time to prepare for your studies. 

The exact deadline for applications varies by course and university, but generally, you should aim to submit your application at least six months before the start of the academic year. Most intakes are in the months of January, May, and September each year.

Many UK universities have rolling admissions, meaning they review applications as they receive them and may fill up their available spots before the official deadline. Applying early can give you a better chance of being accepted before the course becomes full.

In addition, applying early gives you time to prepare for your studies, such as arranging accommodations, obtaining a student visa (if required), and making travel arrangements.
