Net Zero News: Cyber Hack Slashes UK EV Output, Hits Retrofit Funds

Welcome to Net Zero News, where we bring you the latest developments driving the UK’s transition to a net-zero future. Today we report on a significant disruption to domestic automotive output that underscores the interconnected challenges of decarbonisation and digital resilience in the transport sector.

In September, UK car production tumbled by 27.1% compared to the same month last year, according to figures published today by the Society of Motor Manufacturers and Traders (SMMT). Net Zero News understands this sharp decline follows a cyber incident that forced several major assembly lines to halt operations mid-month, triggering a nationwide ripple effect across supply chains and dealership networks.

This incident targeted the digital control systems of multiple manufacturing sites, temporarily shutting down production at facilities operated by leading Original Equipment Manufacturers (OEMs). The breach interrupted just-in-time parts deliveries, disabled automated quality checks and prompted precautionary network isolations. The fallout occurred amid ongoing efforts to ramp up electric vehicle (EV) assembly as part of the UK’s commitment to phase out new petrol and diesel car sales by 2030 and achieve net-zero greenhouse gas emissions by 2050.

The UK automotive sector has invested heavily in electrification over the past decade, with headline projects such as the UK Battery Industrialisation Centre in Warwickshire and gigafactory developments in the North East. These strategic facilities support the government’s aim to produce 1 million EVs annually by 2028. However, the recent cyber disruption has exposed vulnerabilities in digital infrastructure that could delay critical upgrades to production lines and slow progress toward national emission reduction targets.

In a significant step towards the UK’s net-zero goals, industry stakeholders have emphasised the urgent need to bolster cybersecurity frameworks alongside green technology investments. Net Zero News can reveal that the Department for Digital, Culture, Media & Sport (DCMS) is coordinating with the Department for Transport (DfT) and the Department for Business and Trade (DBT) to deploy specialised cybersecurity task forces to key automotive hubs. Early assessments suggest the breach may have set back EV output by up to 10,000 units in September alone, affecting projections for CO₂ savings and regional job growth.

The UK government has already committed over £200 million to expand the national EV chargepoint network and support domestic battery production. In response to the cyber incident, an additional £15 million emergency fund has been earmarked to enhance digital defences in manufacturing. Partnership agreements are being finalised with OEMs including Jaguar Land Rover, Nissan and BMW Mini, as well as technology providers delivering secure cloud services and advanced threat detection solutions.

This response aligns with broader policy frameworks such as the Transport Decarbonisation Plan and the National Cyber Strategy. Net Zero News understands this forms part of a comprehensive mobility review announced in last year’s Energy Security Strategy, which aims to integrate climate resilience measures into future industrial policy. The review will inform updates to the UK’s Critical National Infrastructure (CNI) regulations, ensuring that low-carbon manufacturing remains robust against evolving cyber threats.

The impact of the production shortfall extends beyond factory floors, influencing communities that rely on automotive employment. Regional authorities in the West Midlands and North East have pledged support for affected workers through retraining initiatives focused on digital skills and sustainable manufacturing techniques. Local colleges are coordinating with sector councils to accelerate apprenticeship programmes in EV engineering and cybersecurity, reaffirming the industry’s commitment to a just transition for its workforce.

Looking ahead, carmakers are conducting phased restarts of impacted sites, with full production capacity expected to resume by the end of October. The government’s joint task force will publish its preliminary findings on the cyber incident in early November, recommending long-term investment priorities to safeguard the UK’s green manufacturing ambitions. Stakeholders will closely monitor recovery metrics to ensure that the drive toward zero-emission transport remains on course.
