The restart is expected to take place in a phased manner. Industry sources say restarting the Wolverhampton engine plant is likely to take priority.
However, they expect it to still be several weeks before the production lines are running at full capacity. Suppliers have welcomed the news.
About 30,000 people are directly employed at the company’s UK plants in Solihull, Wolverhampton and Halewood, and about 100,000 work for firms in the supply chain.
Some of these firms supply parts exclusively to JLR, while others sell components to other carmakers as well.
JLR’s supply chain has been under huge financial pressure as a result of the stoppage, with many smaller companies in particular thought to be at risk of bankruptcy.
One supplier told the BBC the news that the restart was welcome and would provide some relief for businesses that rely on orders from JLR, but insisted that the losses already caused meant that financial assistance was still badly needed.
Over the weekend the government announced it would provide loan guarantees worth £1.5bn for JLR, with the stipulation that the supply chain would be supported.
However, the supplier questioned how the money will be distributed – and warned that vulnerable firms could not afford to take on more debt.
