UK Government Launches Formal Review of 2035 Zero Emission Vehicle Mandate

Buying an EV in the UK has quietly become more doable this year — more stock on lots, grants still on the table, running costs easing — and the government now wants to make sure the policy behind that shift doesn't overreach. According to the UK government, ministers opened a formal review of the zero emission vehicle (ZEV) mandate on 14 August to keep the 2030 ban on new petrol cars and the 2035 all-zero-emission target on a realistic footing.

What the review actually covers

The consultation runs until 23 October 2026 and is asking manufacturers, suppliers, charge point operators, dealers, consumers, and communities how the route to "all new cars and vans zero emission by 2035" should be shaped. Ministers stress the headline goal hasn't moved, but say the path needs to absorb "challenging and complex global economic conditions, including supply chain disruption and tariff and trade uncertainty" rather than run on autopilot. Business Secretary Jonathan Reynolds framed the exercise as a way to keep Britain an attractive manufacturing base while still hitting the climate target, with industry given "certainty on the outcome as quickly as possible."

Why buyers should care about deadlines

Even with the review underway, the underlying market data is surprisingly strong. July 2026 was the busiest new-car market since 2019, EV sales rose 45% year on year, and more than one in four new cars sold in the UK now runs on electricity. Over 2 million EVs are registered on UK roads, and the Electric Car Grant — worth up to £3,750 off a new EV — has helped more than 160,000 drivers switch since launching last July, according to government figures. The same release puts running-cost savings at up to £1,400 a year for drivers who make the move, and industry data reportedly shows new EV models are becoming "increasingly comparable in price to petrol and diesel vehicles."

That narrowing price gap is exactly what the mandate was designed to accelerate, and it's why any policy adjustment ripples straight into showroom pricing, dealer allocations, and lease residuals.

What to watch through the autumn

The consultation closes on 23 October 2026, and ministers have signalled they want a clear answer to industry fast. If you're cross-shopping an EV against a hybrid or a plug-in right now, two things are worth tracking: any change to the percentage of EVs manufacturers must sell each year under the mandate, and any sign the £3,750 Electric Car Grant gets extended, recalibrated, or quietly trimmed. Government data already shows manufacturers are on course to hit 2025 targets with built-in flexibilities, so the review reads less like a reversal and more like a mid-course correction.

For most buyers, the practical takeaway hasn't shifted: the direction of travel still points to 100% zero-emission new sales by 2035, the headline incentive is still on the table at the dealership, and the gap between EVs and combustion cars on both sticker price and running costs is still narrowing. A softer mandate might slow that convergence, but it won't refuel your petrol trade-in chart anytime soon.
