Here is everything you need to know about the 2025/26 Scottish Premiership summer transfer window:

When does the Scottish Premiership transfer window open 2025/26?

In a rather unusual fashion, the transfer window is will be split into two separate parts due to the FIFA World Club Cup.

Alongside the English Premier League and several others major league, the Scottish Premiership transfer window opens early this year. It officially opened today (June 1) due to an ‘exceptional registration period’, this is done to allow participating clubs to sign players to take part in the FIFA Club World Cup. This window closes on Tuesday 10 June.

The Scottish Premiership transfer window will then reopen on Monday 16 June.

When does the transfer window close UK, when is transfer deadline day

The transfer window is scheduled to close on on Monday, 1 September at 7pm BST for Scottish Premiership, England Premier League, and EFL clubs.

The phrase ‘deal sheet’ is being used more frequently on deadline day due to the number of last minute deals often made in the run up to the window closing. A deal sheet effectively means if a deal is agreed between two clubs late in the day, additional time may be given by the Scottish FA to complete and submit relevant documentation and paperwork. This can be sent to authorities to indicate the transfer agreement has been reached. This gives clubs an additional two hours to complete all remaining paperwork that would conclude the deal.

Other examples include:

League agreements: Clubs are able to agree transfer with teams from other leagues that have closed transfer windows, and then complete the deals once their own window opens

Free agents: The most obvious exception is that of free agents. If a player is without a club and available as a free agent, clubs in Scotland are able to sign and register the player without an exception.

Emergency deals: If a team requests to sign a player on an emergency basis, special dispensation could be granted to sign player outwith the transfer window. The most obvious example of this is if a team has multiple goalkeepers injured, a team may be allowed to make an emergency loan.
