The warning comes from ticket platform SeatPick ahead of the Manchester band’s London shows, which begin this Friday, July 25.
It follows scenes in Manchester where hundreds gathered on “Gallagher Hill” outside Heaton Park to hear the band perform without tickets.
Gilad Zilberman, CEO of SeatPick, said: “Gallagher Hill quickly became a popular spot, with hundreds of fans enjoying the Heaton Park show without tickets, thanks to the location’s overnight TikTok virality.
“Unfortunately, after speaking with Wembley Stadium, non-ticket holders aren’t welcome.
“They’ve made it clear that fans without tickets will be moved along, and no one is allowed to stand outside any entrance or on the Olympic steps.
“Fans who hoped to enjoy from outside the stadium should take note of the venue’s restrictions.
“And following some rowdy behaviour and arrests at previous UK shows, security is likely to be on high alert.”
The move mirrors crowd control measures introduced during Taylor Swift’s Eras Tour, which saw venues clamp down on “Tay-gating”—fans gathering outside to listen and sing along without tickets.
A spokesman for Wembley Stadium said the rules are in place to ensure fans’ safety.
He said: “To support with the safe entry and exit of everyone within the stadium, no one is allowed to stand outside any entrance or on the Olympic Steps at the front of the stadium.
“Non ticket holders will be moved on.”
SeatPick reports that searches for Oasis tickets at Wembley have surged by more than 5,000 per cent since the tour began.
The platform has listed resale tickets for the London shows starting at £331, with each ticket guaranteed to be valid.
Nearby Wembley Park is hosting an outdoor exhibition of early photos of Noel and Liam Gallagher this summer.
Titled Brothers: Liam and Noel Through the Lens of Kevin Cummins, the free display features more than 20 large-format images taken by renowned music photographer Kevin Cummins during the band’s rise to fame in 1994.
The photographs are on display throughout Wembley Park, including Olympic Way and locations near Wembley Stadium and OVO Arena Wembley.
A Wembley Park spokesperson said: “Across all Oasis concert dates, we’ll be operating our normal event day procedures across Wembley Park. That includes the usual approach to managing public spaces across the estate. As always, our teams will be on hand to ensure a safe and welcoming environment for everyone.”
