The musical drama returns to Fox in the US next month, but Sky1 has decided to hold back the UK premiere in order to "play out... an unbroken run".
In a statement, the broadcaster said: "We originally thought that the majority of our customers would want to see Glee as soon as possible, but last year you gave us feedback about the constant breaks in scheduling (owing to one-off broadcasts of live sport and other events in the US) and told us you wanted a more consistent scheduling pattern.
"We listened to the feedback and have decided to begin showing season 4 in January 2013, so we can play out in an unbroken run."
Spinoff series The Glee Project has also been confirmed to return to Sky1, with an autumn air date being eyed for the reality show's return.
The new season of Glee will feature guest spots from Kate Hudson (Almost Famous) and Sarah Jessica Parker (Sex and the City) and will also introduce four new regular cast members.
