- Cyber Monitoring Center ranks JLR’s incident at level 3 (M&S was level 2)
- Wholesale sales down 24.2% year-on-year, Jaguar undergoing transformation
- The attack cost an estimated £1.9 billion (with £1.5 billion from government loans)
The hack of Jaguar Land Rover (JLR) in August 2025 is estimated to have cost 1.9 billion pounds ($2.6 billion), an official report has said.
A Cyber Monitoring Center report described the incident as “the most economically damaging cyber event to hit the UK”, ranking its effects higher than the effects of the incident that affected M&S earlier in 2025.
Over 5,000 related organizations in the UK have been affected, including suppliers and retailers, extending the impact of the breach.
JLR cyber attack effects
During the shutdown, which lasted around 5-6 weeks, JLR lost an estimated £50 million a week. It later secured a £1.5 billion ($2 billion) government loan to support both its core operations and its suppliers.
Although the systems are back up and running to some extent, it may take until early 2026 for JLR to reach a full recovery state.
JLR’s factories in Solihull, Halewood and Wolverhampton were affected, affecting the company’s 1,000 daily production of cars.
As well as describing JLR’s attack as the “most economically damaging” event in UK history, the Cyber Monitoring Center also categorized the breach as a level three incident, with five being the highest, suggesting potential future attacks could be even more damaging.
To put that into perspective, earlier this year M&S, Co-op and Harrods’ raids scored a level two, with total costs estimated at £270-440m.
However, JLR has still not disclosed what type of attack it faced or whether it paid the ransom (which is not included in the estimate above).
On October 7, JLR recorded a 24.2% year-on-year decline in wholesale sales. “It has been a challenging quarter for JLR. In the first two months our performance was robust and in line with our expectations,” explained CEO Adrian Mardell.
The cyber incident came just months after the company confirmed it would wind down Jaguar sales as the brand undergoes a total reinvention.
“We know there is a lot more to do, but our recovery is well underway,” Mardell added.
