Premier League transfer window 2025: When does it open? When does it close? A complete guide

In just over a week's time, chequebooks will close up and down the country, as the 2025 summer transfer window in England comes to a close.

In the Premier League alone, the ongoing market will go down in history, as an unprecedented £2.4bn has been spent by the 20 top-flight clubs combined, some of whom have been far more active than others.

Florian Wirtz is on course to become the most expensive Premier League player in history at £116m - if his Liverpool add-ons are hit - although he could soon be knocked off his throne by Alexander Isak, if the Newcastle United striker's will wins out.

Here, Sports Mole provides an in-depth breakdown of the 2025 summer transfer window in England.

When did the 2025 summer transfer window open and when does it close?

After the 'exceptional registration period' shut, teams were granted a five-day pause before the second transfer window opened on Monday, June 16.

That market will run for the duration of the summer as is standard, despite reports earlier this year claiming that clubs would discuss closing the window before the start of the season.

Instead, teams will be free to sign and sell players until Monday, September 1, although there will be a countdown to 7pm rather than 11pm this time around as the window is closing four hours earlier.

However, clubs will be expected to have an additional two hours to complete transfers if they have submitted a deal sheet, meaning that some signings may not be announced until 9pm or later on September 1.

What are the biggest deals that could be done this summer?

All eyes are firmly fixed on the unpredictable Isak soap opera, as the Newcastle striker has voiced his desire to sever ties with the Magpies, alleging broken promises from his current club while Liverpool lurk in the background.

Newcastle, in turn, have insisted that no such accords have been unfulfilled, and the North East side remain adamant that he will not be going anywhere unless their £150m valuation is met.

However, Liverpool could instead turn their attention to Real Madrid's Rodrygo, who has allegedly instructed his agents to find him a new club and is also rumoured to have captured the attention of Manchester City.

The Sky Blues could pursue the Brazil international as a successor to Savinho, who is being persistently linked with Tottenham Hotspur after Eberechi Eze snubbed Spurs in favour of Arsenal.

The Gunners could also steal Piero Hincapie from under the Lilywhites' noses, while Chelsea are still hoping to wrap up deals for Xavi Simons and Alejandro Garnacho, and Gianluigi Donnarumma has agreed personal terms with Man City ahead of a possible switch from Paris Saint-Germain.
