JLR has said it will partially resume some production in the coming days after a cyber-attack forced operations to shut down almost a month ago.

The production restart will take place in phases and the Wolverhampton engine plant is expected to take priority

The carmaker had previously announced that its production shutdown, following the hack on 31 August, would run until at least 1 October.

The confirmation of a return to production follows the Government’s announcement over the weekend that it will back JLR with a loan guarantee expected to unlock £1.5bn to support its supply chain, amid concerns that some suppliers could go bust as a result of the shutdowns.

A statement on the carmaker’s site announced: “As the controlled, phased restart of our operations continues, we are taking further steps towards our recovery and the return to manufacture of our world‑class vehicles.

“Today we are informing colleagues, retailers and suppliers that some sections of our manufacturing operations will resume in the coming days.”

JLR added that it would continue to “work around the clock” alongside cybersecurity specialists, the UK Government’s NCSC and law enforcement to ensure “our restart is done in a safe and secure manner”.

“We would like to thank everyone connected with JLR for their continued patience, understanding and support. We know there is much more to do but the foundational work of our recovery is firmly underway, and we will continue to provide updates as we progress,” the luxury carmaker added.

JLR has plants in Solihull and Wolverhampton in the West Midlands, plus Halewood in Merseyside.

The production restart will take place in phases and the Wolverhampton engine plant is expected to take priority.

Some 34,000 people work directly for JLR in the UK and the carmaker also operates the largest supply chain in the UK automotive sector, much of it made up of SMEs, and employing around 120,000 people.

David Bailey, professor of business economics at the University of Birmingham, has said the hit to JLR profits could be as much as £5m a day.

Over the weekend, the Department for Business and Trade said it would underwrite a £1.5bn five-year loan guarantee to JLR.

The loan will come from a commercial bank, through the Export Development Guarantee (EDG) provided by export credit agency UK Export Finance.

Business and Trade Secretary Peter Kyle said: “This cyber-attack was not only an assault on an iconic British brand, but on our world-leading automotive sector and the men and women whose livelihoods depend on it.

“Following our decisive action, this loan guarantee will help support the supply chain and protect skilled jobs in the West Midlands, Merseyside and throughout the UK.”

Leading union Unite, which represents many thousands of works employed at JLR and throughout its supply chain, said the financial support was an “important first step” and “demonstrates that the Government has listened to the concerns raised in meetings with Unite over recent days”.

Unite general secretary Sharon Graham said: “This is exactly what the Government should be doing, taking action to protect jobs.

“The money provided must now be used to ensure job guarantees and to also protect skills and pay in JLR and its supply chain.”
