New EV Tax Could Cost Economy Billions, Association Warns

Why It Matters

If implemented as scheduled, eVED could undermine the UK’s EV adoption rate, erode tax revenues and increase costs for lower‑income drivers, jeopardizing climate goals and the broader automotive supply chain.

Key Takeaways

• BEAMA warns eVED could cost UK up to £4.8 bn ($6.1 bn) in 2028.
• Even with petrol car replacement, £890 m ($1.1 bn) tax loss remains.
• Industry groups urge delaying eVED rollout to 2030 for stability.
• 3p per mile tax may deter EV adoption and burden low‑income drivers.
• Potential fraud and compliance costs could outweigh expected revenue gains.

Pulse Analysis

The Treasury’s eVED proposal reflects a growing need to rebalance road‑use contributions as electric cars displace fuel‑tax revenues. By setting the charge at half the rate of traditional fuel duty, policymakers aim to preserve incentives for clean‑vehicle uptake while ensuring all motorists help fund congestion and wear‑and‑tear. However, the shift from a flat vehicle excise duty to a mileage‑based levy introduces a variable cost that could erode the price advantage of EVs, especially for drivers without private charging facilities.

Industry groups argue the timing is premature. BEAMA’s analysis, anchored in New Zealand’s experience, projects a worst‑case fiscal hit of £4.8 bn ($6.1 bn) in 2028, driven by reduced EV sales and associated VAT losses. Even a scenario where EV demand is offset by petrol‑car sales still leaves a £890 m ($1.1 bn) shortfall. The three‑pence‑per‑mile charge also raises equity concerns, potentially pricing out lower‑ and middle‑income households and discouraging the very market growth the government seeks to accelerate.

Globally, jurisdictions that have introduced mileage‑based EV taxes have seen mixed results, with some experiencing slower adoption and heightened administrative burdens. Delaying eVED to 2030 would give manufacturers and charging‑network operators time to scale infrastructure, solidify consumer confidence, and refine the tax mechanism to mitigate fraud risks. A calibrated approach could preserve revenue goals while sustaining the UK’s ambition to lead the transition to zero‑emission transport.
