As English soccer's top-tier Women's Super League (WSL) prepares to get its 2025-26 season underway tomorrow (September 5), the property has signed up another commercial partner.

Through a multi-year agreement unveiled today, UK electricity supplier British Gas has signed up as a league sponsor, in a deal also covering the second-tier WSL 2.

From the start of 2025-26, British Gas will be rewarding customers with WSL and WSL 2 tickets and experiences, while both parties have said an ambition for the deal is to "tap into British Gas expertise to create sustainable pitch protection options for the future of football."

The 2025-26 season of the 12-team WSL begins tomorrow, as champions Chelsea take on Manchester City at Stamford Bridge.

In terms of WSL commercial activity, this week has already seen the announcement of an expanded deal between the WSL and sportswear giant Nike.

Nike has signed on as a partner of the WSL, the WSL 2, and the Women's League Cup knockout competition.

This adds to an existing partnership between the WSL and Nike, through which the brand has been the competition's ball supplier since the start of the 2022-23 campaign. GlobalData Sport has valued that deal - which will also continue through to 2028 - at the equivalent of $1.25 million per season.

The new deal entails Nike launching league-branded merchandise in collaboration with the WSL Football body, and also providing soccer boots and goalkeeping gloves to all WSL and WSL 2 players who do not currently have personal deals of that nature in place.

Barclays title sponsors the WSL and WSL 2, meanwhile, in a tie-up running through 2027-28 that GlobalData Sport has valued at the equivalent of $20 million annually.

WSL Football was rebranded as such in late June, from its previous name of Women’s Professional Leagues Limited (WPLL).

The rebrand was the first major change WSL Football made since it assumed control of the top two tiers from the Football Association (FA) in August 2024.
