The transfer deadline day for the 2025 summer transfer window for Premier League, EFL, LaLiga, Bundesliga, Serie A, and Ligue 1 clubs is Monday, September 1, 2025, at 7:00 PM BST (UK time). This is a slightly earlier closing time than usual, which traditionally was 11:00 PM. The deadline falls one day later than usual this year because August 31 falls on a Sunday. The Women's Super League transfer window closes later, at 11:00 PM on Thursday, September 4, 2025. The Saudi Pro League transfer window closes on September 10, 2025. So, the official deadline day is Monday, September 1, 2025, with the window closing at 7 PM BST for major European leagues including the Premier League.
