UK MPs Warn Over Chinese EV Security Threat

The debate over Chinese EV security has moved from industry whispers to the centre of Westminster. In a report published on November 2, 2026, the House of Commons Business, Innovation, Science and Trade Committee accused the government of making up its China policy "as it goes along" — and put Chinese-made cars and connected technology squarely in the firing line.
The committee's headline demand is blunt: as MPs demand in their call for a ban on Chinese tech, Chinese-made technology should be kept out of Britain's critical national infrastructure, and ministers should identify and progressively replace connected tech made in high-risk countries with trusted alternatives.
Key Takeaways
- MPs urge a ban on Chinese-made connected technology in critical national infrastructure, singling out vehicles used by government, defence and emergency services.
- The report calls for urgent talks with telecoms firms to monitor data flowing between connected cars and foreign manufacturers.
- Chinese-built and Chinese-owned EV and hybrid brands now account for roughly a quarter of UK new-car sales, according to SMMT data — embraced as a cheaper route to electrification.
- MPs recommend new trade defences, including possible EV tariffs, a "red zone" closed to Chinese investment and a "green zone" where trade is encouraged; Downing Street has not ruled tariffs out.
What the MPs concluded
The report warns that increasingly sophisticated Chinese technology has become embedded in British infrastructure, leaving the country exposed to surveillance and disruption in the event of an international crisis. The committee says ministers should systematically find connected technology made in high-risk countries — including equipment used in essential services — and replace it.
Cars are named explicitly. "The government should focus on vehicles used in critical national infrastructure sectors, notably government, defence, and the emergency services," the report says. The fear is twofold: that sensitive information could be siphoned off, and that Beijing could one day remotely disable vehicles in a crisis.
To address the data question, MPs demanded urgent talks with telecoms companies to monitor the data transmitted between connected vehicles and foreign manufacturers. The committee argued these links leave vehicles vulnerable to hacking or remote sabotage by hostile states.
The report also takes aim at the government's reluctance to name names. The committee said ministers had resisted proposals to create a register of countries posing a threat to networks, preferring to assess suppliers one by one. MPs argued that approach could be easily sidestepped by foreign companies operating under different names — and said a ban would only work if ministers properly identified the affected equipment and replaced it.
Crucially, the committee did not frame this as a call to rip out every Chinese-made component overnight. Its recommendation is a managed, progressive replacement of connected technology in sensitive sectors, with ministers reporting back to parliament on progress in a year's time.
Why cars are in the crosshairs

Modern electric cars are, in the committee's view, computers on wheels — and that is what worries MPs. Connected vehicles can receive over-the-air software updates, the same mechanism that lets manufacturers add features and fix bugs. The committee's concern is that this two-way channel could, in theory, be used to control or disable a vehicle remotely — a scenario sometimes described as "bricking".
Then there is the question of what the car sees and hears. Modern EVs carry cameras, microphones and a suite of sensors, and the report raises the fear that Chinese security services could require China-based manufacturers to grant access to those systems, using the data for intelligence purposes or disrupting foreign transport and logistics networks.
One figure cited by the committee underlines how deep the dependence runs: Chinese manufacturers account for up to 79 per cent of the global market for cellular internet-of-things modules — the components that let vehicles, payment terminals and other equipment communicate over mobile networks. Their widespread use, the report said, has increased Britain's exposure to interference and dependence on Chinese supply chains.
The report pointed to a Norwegian investigation into a Chinese-made Yutong bus, which found that access to equipment connected to the battery and engine could be gained remotely. To be fair, the committee acknowledged the limits of that example: Yutong buses sold in Britain cannot receive over-the-air software updates, and ministers have assessed their software security as meeting government expectations. But MPs said the case showed why tighter oversight of connected vehicles was needed.
The committee's proposed principle is narrower than an outright ban on Chinese cars. It concludes that EVs and other connected devices of Chinese origin need stronger safeguards: in the case of connected cars, vendors should only send and receive data strictly necessary for maintaining the vehicle — and never data that would let them control or disable it remotely.
The quarter-of-the-market reality

Here is the awkward context MPs cannot avoid. Chinese-owned and China-built electric and hybrid vehicle brands have captured roughly a quarter of the UK new car market from a standing start, according to SMMT data highlighted in National Sustainability News' analysis of the surge. They have been welcomed — by buyers and policymakers alike — as a generally cheaper way to speed up the adoption of greener technology.
That popularity is exactly why the committee's warnings land with such force. The UK has not acted with the same force as the European Union, which has imposed tariffs on Chinese EVs, capped the number of hybrid cars that can be imported from China, and is now weighing a Franco-German proposal for a "kill switch" to block imports if Beijing weaponises trade. Britain's lighter touch has left it an outlier — deliberately, in part, to keep electrification affordable, but increasingly uncomfortable as Brussels hardens its stance.
Committee chair Liam Byrne, the Labour MP who led the inquiry, pulled no punches on the policy vacuum. "Britain's businesses cannot plan for the future when the government keeps making up its China policy as it goes along," he said. "Ministers promised clarity and consistency. Instead, we have opportunities missed, risks unmanaged and decisions left until the eleventh hour."
The report argues this drift leaves the UK exposed to being trapped between two bigger players: "Britain must shape its own relationship with China, or risk having that relationship shaped for us in Washington or Beijing."
What happens next

The committee wants a new rulebook for the China relationship. It recommends new trade remedies to counter unfair competition, including potential tariffs on EVs — something Downing Street has not ruled out, with the business secretary saying he will decide in the best interests of the UK.
Ministers should also designate a "red zone" of strategic capabilities the UK must keep sovereign and off-limits to Chinese trade and investment, alongside a "green zone" where trade should be encouraged with targeted support for businesses — especially small firms — through better market access, more export finance and clearer guidance.
Looking outward, Byrne said the UK should be prepared to consider "dynamic alignment" with the EU on tariffs, including on EVs, as the price of securing British firms a place in the EU's Made in Europe project and guarding against Chinese dominance. New EU trade protections, he warned, "may trap Britain outside EU trade walls, cutting us off from our largest market".
The report also pointed to recent reactive decisions as evidence of the problem: the blocking in March of Chinese firm Ming Yang's £1.5 billion wind energy project in Scotland after years of negotiation, and the emergency takeover of British Steel from its Chinese owners. Both, the committee said, were characterised by "reactivity, inconsistency and opacity".
For its part, the government pushed back. A spokesperson said: "We recognise the committee's work on this report, but we disagree with its conclusion. Our approach to China is consistent — we will co-operate where we can and challenge where we must. We have placed our relationship on a more stable, balanced, long-term footing, and based it on a clear-eyed assessment of both the opportunities and the risks."
Ministers will now have a year to show progress before reporting back to parliament. For the quarter of the new-car market that runs on Chinese-built or Chinese-owned hardware, the scrutiny is only just beginning — and the way Britain answers the Chinese EV security question will shape not just its roads, but its trade relationship with two of the world's biggest powers.
