Fans will be able to buy water in the stadium and Fifa has promised not to charge above their usual venue prices.

The U-turn follows warnings by scientists that Fifa’s heat safety measures for the tournament are “inadequate”, with temperatures at 14 of the 16 host venues set to exceed dangerous levels.

“Fifa works closely with each host city committee and local authorities on heat mitigation factors for fans travelling to the stadium, which can include resources such as misting stations, fans, hydration stations, cooling tents and more around the stadium footprint,” Fifa’s statement said.

“Inside the stadium footprint, pricing for water bottles for the Fifa World Cup 2026 will remain consistent with other events held at each stadium.”

The change in policy comes amid complaints that fans are being hit by “extortionate” ticket prices and inflated train fares.

Fans were also prevented from taking bottles into stadiums at the last World Cup in Qatar.

The Free Lions England fans’ group called the move a “strange, late change”.

In a statement posted on X, it added: “In all of our discussions, free water availability in stadiums was a key one and we were assured by Fifa that this would be the case and that fans will have the ability to bring their own water bottle.

“Naturally, the immediate thought from supporters is this is just the latest money-grab. For how hot the stadiums will be, many in open air, just let fans bring a bottle if they want to.

“We hope the water fountains in stadiums will still be free, hopefully you aren’t charged in the queue!”
