Dominik Szoboszlai, Moises Caicedo and Declan Rice were among those to move clubs during the summer transfer window
The combined outlay of the 20 clubs during the window smashes the previous spending record of £1.92bn set last summer by £440m, according to financial services firm Deloitte.
Premier League clubs spent £255m on deadline day alone, which is more than double the £120m spent on deadline day during last summer's window.
That already makes the 2023-24 season have the second-highest transfer spend ever after last season's record £2.73bn, with the January window still to come.
Other records include:
Tim Bridge, lead partner in Deloitte's Sports Business Group, said: "A second successive summer of record spending by Premier League clubs suggests that year-on-year revenue growth could return following the pandemic
"Nearly three quarters of Premier League clubs (14) spent more this summer than the last, reflecting the increased intensity of competition.
"There continues to be pressure on clubs to acquire top talent to satisfy their on-pitch objectives, whether that's qualifying for European competition or simply maintaining their position in the Premier League."
