It is the first of two transfer deadlines for Premier League and English Football League clubs at 23:00 BST on Monday.
It is the final date for international signings or moves between Premier League clubs.
However, English Football League clubs can still sign domestic players, and Premier League teams can sign EFL players, until 17:00 on Friday, 16 October.
The transfer window in Scotland closes at midnight on 5 October.
The deadline in Europe’s other top leagues – Bundesliga, La Liga, Ligue 1 and Serie A – are all on Monday too. That is the date European football’s governing body, Uefa, asked leagues to close their window by.
Players have to be registered for the Champions League and Europa League by 6 October.
