UK Car Industry Pushes for Two-Year Delay to Brexit EV Tariffs 2026

The UK car industry is preparing to press the EU for a two-year delay to Brexit tariffs on electric cars, after an initial European proposal suggested a shorter postponement. The tariffs, set to hit on 1 January, would impose a 10% duty on the majority of electric vehicles traded between the UK and EU unless both sides agree to waive "rules of origin" requirements for batteries for a second time.

The rules, introduced in the rushed Christmas Eve 2020 Brexit deal, require British and European electric cars to use batteries made in the UK or EU with local materials—or face the levy. These rules would not exist had the UK remained in the EU. They were originally due to take effect on 1 January 2024, designed to incentivise investment in local lithium-ion battery manufacturing and reduce reliance on Chinese battery suppliers.

Why the Rules of Origin Matter for EV Tariffs

Rules of origin determine where a product is considered to have been made. For electric vehicles, the battery is the most valuable component, so the rules effectively demand that batteries and their components originate locally. The goal was to build a domestic battery supply chain and lessen dependence on China, which dominates global battery production.

However, three years after the Brexit deal, several prominent battery projects on both sides of the Channel have collapsed. While some new projects have emerged, many are not yet producing at the scale needed to meet European demand. As a result, carmakers remain heavily reliant on imports from China, Japan and South Korea.

Industry Calls for a Second Delay

Carmakers in the UK and Europe are united in their calls for a delay to the rules of origin. They argue that the domestic battery supply chain is not ready, and imposing tariffs now would raise costs for consumers and slow the transition to electric vehicles. The EU initially proposed a shorter delay, but the UK industry is pushing for two years to give battery manufacturers more time to scale up.

The UK government has not publicly commented on the specific duration, but it is understood to be sympathetic to the industry's concerns. The EU's proposal is seen as a starting point for negotiations, with both sides keen to avoid a trade dispute.

What the Tariffs Would Mean for Consumers

If the tariffs go ahead, the 10% duty would likely be passed on to consumers in the form of higher prices for electric cars. This could dampen demand at a time when governments are trying to encourage EV adoption. The UK's zero-emission vehicle mandate, which requires a growing share of new car sales to be electric, could be undermined by higher prices.

For carmakers, the tariffs would add cost and complexity to cross-Channel trade. Many models are built in one country and sold in the other, so the rules would affect a significant portion of the market. The Society of Motor Manufacturers and Traders (SMMT) has warned that the tariffs would be a "double whammy" for the industry, which is already facing stiff competition from Chinese EV makers.

The Broader Context: Battery Investment and Trade Tensions

The delay request comes amid broader trade tensions. The EU has imposed tariffs on Chinese tires, and the US is considering tariffs on generic drugs. The UK car industry is also grappling with the fallout from the collapse of Britishvolt, a high-profile battery startup, and the scaling back of other projects.

In this context, a delay to the EV tariffs is seen as a pragmatic step to avoid disrupting the market while the battery supply chain matures. The EU and UK have already extended the deadline once, in December 2023, and another extension would provide temporary relief.

What to Watch Next

Negotiations between the UK and EU are expected to continue in the coming weeks. The key questions are the length of any delay and whether it will be accompanied by commitments to invest in domestic battery production. The industry is watching closely, as the outcome will shape investment decisions and pricing strategies.

For now, carmakers are urging both sides to act swiftly to avoid a cliff-edge on 1 January. A two-year delay would give battery manufacturers time to scale up, but it would also delay the intended benefits of the rules. The balance between short-term relief and long-term industrial policy is delicate. Earlier coverage in Stellantis and Renault Back UK for EU Car Industry Protection shows how the argument developed.

• UK car industry seeks a two-year delay to Brexit EV tariffs, longer than the EU's initial proposal.
• Rules of origin require EV batteries to be made in the UK or EU, or face 10% tariffs from 1 January.
• Domestic battery supply chain is not ready, with several projects collapsing and reliance on Asian imports persisting.
• Tariffs would likely raise EV prices and slow adoption, undermining climate goals.
• Negotiations are ongoing, with the length of delay and investment commitments key.

The outcome of these negotiations will have significant implications for the UK's automotive sector and its transition to electric vehicles. As the deadline approaches, stakeholders are closely monitoring developments.

Meanwhile, uncertainty over the rules has already led some carmakers to delay UK EV investment until the rules are relaxed. This hesitation could impact the UK's ability to attract battery gigafactories and create jobs. More on that can be found here: Carmakers Delay UK EV Investment Until Rules Relaxed.

The broader trade environment is also shifting, with the EU imposing tariffs up to 45% on Chinese tires, which could have ripple effects on the automotive supply chain. Understanding these developments is crucial for industry watchers: EU Imposes Tariffs Up to 45% on Chinese Tires.

In addition, the US is considering tariffs on generic drugs, showing a global trend toward protectionism that could influence EU-UK negotiations. For context, see: Trump Generic Drug Tariffs 2028: Impact on Prices.
