The summer transfer window for most major European football leagues, including the Premier League and EFL, closes on Monday, September 1, 2025, at 7:00 PM BST (British Summer Time). This is slightly earlier than the traditional 11:00 PM deadline in previous seasons. The change was made to allow a more normal working pattern for football staff. For leagues like LaLiga, the window closes the same day but later at 10:59 PM BST. Deals for free agents not attached to any club can still be made after this deadline.
