EV target rethink tests policy certainty

The government is preparing to soften the trajectory for electric vehicle sales, giving carmakers more room to sell hybrids through the rest of the decade while retaining the 2030 phase-out of new purely petrol and diesel cars.

The current zero emission vehicle mandate, introduced under the previous Conservative government, requires 80% of new cars and 70% of new vans sold in Great Britain to be zero emission by 2030, rising to 100% by 2035. Under the proposed change, the 2030 fully electric car sales requirement would fall to 50%, allowing hybrid vehicles to account for a much larger share of sales before the 2035 end date for new hybrid cars.

The change would mark another recalibration of one of the UK’s most commercially sensitive net zero policies. The 2030 end of sale date for new cars powered solely by internal combustion engines was restored in 2025, with ministers confirming that all new cars sold from that point would need to be hybridised in some manner or zero emission. That structure kept the ban on pure petrol and diesel cars while leaving room to adjust the pace of fully electric adoption.

Market data helps explain the pressure on policy. The Society of Motor Manufacturers and Traders shows battery electric vehicles accounted for 23.9% of UK new car registrations year to date in 2026, up from 20.9% in the same period of 2025. Plug-in hybrids accounted for 13.1%, while hybrids accounted for 14.3%. Battery electric registrations are increasing, but the sector remains below the 2026 mandate trajectory of 33%.

For car manufacturers, the gap between mandated sales and consumer demand creates pressure across pricing, production, and distribution. Companies can discount electric vehicles to lift volumes, use compliance flexibilities, buy credits, or change the mix of models supplied to the UK market. Each option affects margins, dealer incentives, residual values, and consumer choice.

Fleet operators, leasing companies, charging providers, and energy infrastructure investors are also exposed to any change in trajectory. Slower battery electric penetration may reduce near-term strain on charging networks, but it can also weaken demand forecasts used to justify investment. Charging infrastructure depends on utilisation, location economics, grid connection timelines, and predictable vehicle uptake.

The policy sits inside a broader manufacturing challenge. Automotive investment is being contested globally, with the US, EU, China, Japan, and South Korea competing for battery, power electronics, software, and assembly capacity. A softer mandate may ease short-term compliance pressure on incumbent manufacturers, but repeated adjustments can make long-term capital allocation harder. Production lines, supplier contracts, battery sourcing, and model launches require decisions that run years ahead of consumer sales.

The commercial case for electric vehicles has become more complicated, even as adoption grows. Running costs can be lower when vehicles are charged cheaply and used predictably, but purchase prices, insurance, public charging costs, residual values, and vehicle suitability still vary widely. Depot-based fleets and high-utilisation vehicles may move faster than private drivers who rely on public charging or live in homes without off-street parking.

Fleet transition decisions affect benefit-in-kind planning, mileage reimbursement, employee charging access, logistics costs, and vehicle replacement cycles. Many organisations are already weighing electric vans, company cars, charging infrastructure, and route planning against higher capital costs and uncertain residual values. The policy framework shapes those calculations because fleets cannot easily reverse procurement decisions once vehicles, chargers, and energy contracts are in place.

Manufacturers, infrastructure investors, environmental groups, fleet managers, and consumers each measure certainty differently. Carmakers want a sales trajectory aligned with production economics and demand. Charging providers want confidence that utilisation will rise quickly enough to justify sites. Environmental groups want binding emissions reductions. Fleets want a procurement path that does not create stranded costs.

The ZEV mandate has always been more than an emissions rule. It is an industrial policy tool, a consumer market intervention, and an infrastructure planning signal. Reducing the 2030 fully electric target would ease immediate compliance pressure, but it would also change assumptions across charging investment, battery supply chains, grid planning, insurance pricing, and automotive transition finance.

The UK can still grow a large electric vehicle market with a more flexible hybrid phase, but credibility will depend on consistency. The industry can adapt to demanding rules, and it can adapt to softer rules. It struggles most when long-term policy shifts faster than investment cycles.
