This is a list of English football transfers for the 2017 summer transfer window. Only moves featuring at least one Premier League or Championship club are listed. The summer transfer window began once clubs had concluded their final domestic fixture of the 2016–17 season, but many transfers only officially went through on 1 July because the majority of player contracts finished on 30 June. The window remained open until 18:00 BST on 1 September 2017. The window shut at 18:00 BST this time due to the UEFA player registration deadlines for both the Champions League and Europa League ending at 23:00 BST, giving the 6 sides still in Europe time to conclude deals and register their player for continental matches if appropriate.
