This compares to a £49.8m loss for the year before, new business filings for Williams Grand Prix Engineering Ltd reveal.
So far this season, Williams are having an underwhelming fight in the F1 constructors’ fight, earning just 11 points and down in ninth before the Grand Prix in Azerbaijan.
On the business side, the Grove-based team saw revenue climb to £244m for the year ending December 31, up from £179.8m the previous year.
The Grove-based team have also recruited just over 200 more employees in the past year, taking the total headcount to 1,151 people.

On the £25.1m loss, Williams said: “Whilst the group remains in a loss position, this is in line with expectations and the group’s strategy to continue investing in all areas of the business to drive both on-track and commercial performance in pursuit of success in the medium and long-term.”
The team said the increase in revenue was driven by higher sponsorship income from new and existing commercial partners, though this was partially offset by lower commercial rights revenue following a ninth-place finish in the 2024 Constructors’ Championship.
Williams described 2025 as its most successful season since 2016, finishing fifth in the Constructors’ Championship with 137 points and achieving podiums in Baku and Qatar.
The team also secured its first-ever sprint podium in Austin where Carlos Sainz finished third.
Drivers Alex Albon and Carlos Sainz finished eighth and ninth respectively in the Drivers’ Championship.
Williams said the results demonstrated the “significant progress being made by the team in line with the long-term plan to return to the front of the grid through continued investment in infrastructure, people and technology”.
Williams also reported growth in its commercial partnerships during 2025, including the addition of title partner Atlassian.
Other new sponsors included Super Group, NMC2, Airia, Brillio and Santander.
The team added: “Driven by a dedication to bring fans closer than ever to the sport, Williams grew its global fanbase to over 400m fans and was the fastest-growing F1 team on social media.”
Williams also invested in its Driver Academy programme, supporting talent development across the motorsport ladder.
Its STEM outreach programme brought more than 12,000 young people to the Grove headquarters during the year.
The company said it remains committed to returning Williams to the front of the grid, guided by values of innovation, teamwork, resilience, excellence and accountability.
Despite the losses, the company reported net assets of £98.6m as of December 31, 2025, down from £130.1m the previous year.
Williams also restructured during the year, transferring much of its trade and assets to the newly formed Williams Grand Prix Engineering Services LLP.
The company said this update “makes the organisation fit for the future” after nearly 50 years of operation under its previous structure.
