JLR Cyberattack Pegged at £1.9 Billion, UK’s Costliest to Date, CMC Says

The independent monitor labels the late‑August breach a Category 3 systemic event after a month‑long shutdown cascaded through the carmaker’s supply chain.

Overview

  • Production was halted for roughly five to six weeks from 1 September, with a phased restart in October and full output modelled to return by early January 2026.
  • More than 5,000 UK organisations were affected, and the vast majority of losses reflect missing manufacturing output at JLR and suppliers, with the company bearing over half the modelled cost.
  • The UK government offered a £1.5bn loan guarantee to bolster supplier cash flow, while JLR launched accelerated supplier financing and manual payment processes during the restart.
  • The CMC’s model puts total losses in a £1.6bn–£2.1bn range and warns they could grow if recovery slips or operational technology problems surface, with global impacts excluded.
  • Industry data show UK car production fell 27.1% month on month in September, with the JLR shutdown a major factor in the decline.
