ZEV Mandate Consultation 2026: What It Means for You

On 14 August 2026 the government opened a consultation asking whether the Zero Emission Vehicle (ZEV) mandate, the rule that forces car makers to sell a rising share of electric cars each year, should be softened. If you're wondering what the ZEV mandate consultation 2026 actually proposes and whether it changes anything for you as a driver right now, the short answer is: not yet, but it could reshape the next few years of new car choice. Here's what's genuinely on the table, what's staying put, and what it means if you're buying, selling or running a car over the next few years.

This isn't a brand new idea dressed up as news. The review was already promised for early 2027, but it's been brought forward following a previous review in 2025 that introduced new flexibilities while also allowing new hybrid cars on sale until 2035, and it delivers on the long-standing commitment to review the mandate by 2027. What's genuinely new is that ministers have moved the timetable up by a year and put concrete numbers on the table for how far targets could be relaxed.

What the ZEV mandate actually requires right now

The mandate sets a rising percentage of each manufacturer's new car and van sales that must be zero emission every year. The current mandate, introduced in 2024, required that 22 per cent of a car manufacturer's sales that year be electric. This rose to 28 per cent in 2025 and 33 per cent this year. On the current trajectory, that climbs further: manufacturers would be required to meet a 52 per cent EV target in 2028, 66 per cent in 2029 and 80 per cent in 2030. Vans follow a similar, slightly gentler curve, with a headline target of 70% zero emission by 2030.

Manufacturers don't have to hit these numbers through pure sales alone. The mandate already includes flexibilities such as banking unused allowance from previous years, borrowing against future years, and earning credit for cutting the average CO2 emissions of the petrol and diesel cars they still sell. Using those mechanisms, the new car market technically exceeded the 22% ZEV Mandate target for 2024, even though real-world electric sales alone were running behind that figure.

Why the government has opened this consultation now

Ministers say the case for a rethink comes down to conditions the mandate wasn't designed for. According to the GOV.UK announcement, the consultation is delivering on the government's promise to keep the mandate under review to ensure it remains fair for industry and continues to drive growth, is responsive to global markets and delivers choice for consumers, starting the review now to give industry certainty on the outcome as quickly as possible. Industry lobbying has pointed to challenging and complex global economic conditions, including supply chain disruption and tariff and trade uncertainty, along with changing standards in Europe and the US as reasons the pace of change needs another look.

It's worth being clear that this isn't happening because the transition has stalled. Quite the opposite: July recorded the strongest new car market since 2019, driven by growing demand for electric vehicles, with more than 1 in 4 new cars sold now electric, EV sales up 45% on July last year, and over 2 million electric vehicles now registered on UK roads. The argument from manufacturers isn't that EVs aren't selling, it's that the mandate's annual targets are rising faster than real-world consumer demand in the current economic climate.

What could actually change

Targets for cars

The consultation doesn't propose scrapping the mandate, it proposes flexing the trajectory towards 2030. Options on the table range from keeping the existing 80% target with extended flexibilities, through to considerably softer paths. A new consultation launched by the government could see that 2030 figure cut to 70, 60 or even 50 per cent, with another option on the table being to keep the 80 per cent target but give car makers more flexibility over how they meet it.

Targets for vans

Vans get their own set of options, reflecting the fact that electric vans have had a harder time catching on with fleets and tradespeople. For electric vans the 2030 target is 70% by 2030, and consultation options range from a 40% target by 2030 to 70% with extended flexibilities.

The flexibilities themselves

Alongside the headline percentages, the consultation is also examining the mechanics manufacturers use to comply, including banking, borrowing and CO2-based credit transfer. These technical details matter more to manufacturers and fleet buyers than to individual drivers, but they can affect how quickly genuinely electric models arrive in showrooms versus how much manufacturers can lean on hybrids and cleaner combustion cars in the meantime.

What isn't changing

Whatever comes out of this consultation, two dates remain fixed for now. The government has been explicit that the end goal hasn't changed, with new petrol and diesel cars still due to be phased out by 2030, and all cars and vans required to be zero emission by 2035. So if you're weighing up whether to buy a petrol or diesel car in the next few years, the phase-out date for new sales of those cars hasn't moved. What's up for debate is how steeply manufacturers must ramp up electric sales in the years running up to that 2030 point, not whether 2030 and 2035 apply at all.

What it means for you right now

For anyone buying, selling or simply running a car today, nothing changes immediately. This is a consultation, not new law, and it won't be settled until responses have been considered after the closing date. In practical terms:

• You can still buy a new petrol, diesel, hybrid or electric car exactly as you would today, with no new restriction taking effect during the consultation period.
• If you're considering an electric car, the government's Electric Car Grant remains available in the meantime; it offers up to £3,750 off the cost of a new EV and has already helped over 160,000 drivers buy an EV since it launched last July.
• Manufacturers may adjust pricing, discounting or model availability while the outcome is uncertain, so it's worth shopping around and comparing deals rather than assuming today's offers will still be there in a year's time.

If you're weighing up a used petrol, diesel or electric car while all this plays out, it still pays to check the basics before you commit.

How to have your say

This consultation isn't just for car makers. Vehicle manufacturers, suppliers, charge point operators, dealers, consumers and communities are being asked for their views on the pathway to 2030 and 2035. If you have a view on how quickly the electric transition should happen, or how it affects your own choice of vehicle, the ZEV Mandate review consultation, launched by the UK and devolved governments, will run until 23 October 2026, giving you roughly ten weeks to respond through the official consultation channels on GOV.UK.

What happens next

Once the consultation closes on 23 October 2026, the government will need to weigh up the responses and decide whether, and how far, to soften the targets running up to 2030. Given the pressure to give manufacturers certainty, a response is likely to follow reasonably quickly rather than drag on for months, though no firm date has been set. Until then, the sensible approach is to keep buying the car that suits your budget and needs today, keep an eye on how the targets and any grant schemes evolve, and check the practical basics like MOT history, tax status and a rough valuation before you commit to any used car, petrol, diesel or electric.

The ZEV mandate percentages, van targets and Electric Car Grant terms referenced here can all change once the consultation closes, so check the latest position on the GOV.UK announcement or the Department for Transport before making any buying decision based on them.
