Softer EV Targets on the Way? What a Weaker ZEV Mandate Means for UK Drivers

Most drivers will never read a line of the Vehicle Emissions Trading Schemes Order. But sooner or later they feel its effects: in the price of a new car, in whether the charger at the supermarket works, or in what a three-year-old hatchback is worth on the forecourt.

That is why the latest news deserves a closer look. According to The Guardian, the government is expected to weaken the zero-emission vehicle (ZEV) sales mandate, which sets targets for the share of new cars that must be electric. MPs and climate campaigners have raised concerns.

Here is what that could mean once you strip away the Westminster noise.

What happened

The ZEV mandate is the rule that tells carmakers how many of their new car sales in Great Britain must be zero-emission each year. It started in January 2024 with a 22% requirement. The original schedule then climbed year by year, to 28% in 2025 and 33% in 2026, reaching 80% in 2030 and 100% by 2035.

Two things are important to understand about it:

• It applies to manufacturers, not drivers. Nobody is legally required to buy an electric car. The obligation falls on the companies selling new vehicles.
• It works through credits and penalties. Carmakers that fall short can buy credits from rivals, use certain flexibilities, or face financial penalties.

The mandate has already been softened once. In 2025 the government confirmed that hybrids could continue to be sold until 2035 and eased some of the penalty and flexibility arrangements. The Guardian's report suggests another round of weakening is now expected. Its summary does not set out the precise new percentages, so it would be unwise to guess at them. Wait for the published detail before drawing firm conclusions about any specific year.

If you want the earlier context, our posts on the UK set to soften its 2030 EV sales target and the review of ZEV mandate targets cover how this debate has developed.

Why it matters, even if you are not buying a new car

It is tempting to see this as a story for the car industry and climate campaigners. In practice the ripples reach ordinary drivers in several ways.

1. The price and availability of new EVs

The mandate gives manufacturers a strong reason to push electric models, including through discounting. A lower target reduces that pressure. Carmakers have argued that the targets run ahead of consumer demand. Campaigners and some MPs say a weaker target removes the push that has helped bring prices down. Both sides are making a real argument, and what happens to showroom prices will depend on how far the targets move.

2. The used car market

Today's new-car sales shape tomorrow's used market. A slower shift in new sales would mean fewer used EVs arriving over the coming years. That could affect both choice and price for drivers who rely on used cars. It is also a reminder that residual values for any vehicle type are hard to predict, so treat anyone's confident forecast with caution.

3. Charging infrastructure confidence

Companies building public chargers invest on the expectation that demand will follow. Policy wobbles can make investment more cautious. That matters for drivers without driveways, who depend on public and on-street charging. Our coverage of the UK EV charger rollout slowing as costs rise looks at this tension.

4. Fleet and business decisions

Company fleets drive a large part of new-car registrations. Uncertainty about targets can lead fleet managers to delay decisions, which then feeds into the used market a few years later.

5. The climate and legal backdrop

The UK has a legally binding net zero target for 2050 under the Climate Change Act 2008, as amended in 2019, plus a system of carbon budgets. Road transport is a major source of emissions, which is why MPs and campaigners see the mandate as a key lever. A weaker target does not itself change those legal duties, but it can increase pressure to find savings elsewhere. That is one reason debates on road pricing and vehicle taxes keep coming up.

The legal angle: what changes, and what does not

Let us be clear about what a change to the ZEV mandate would and would not do.

What it would change

• The obligations on manufacturers. These sit in secondary legislation, the Vehicle Emissions Trading Schemes Order 2023 and its amendments. Changing the targets means changing that legislation, which brings some level of parliamentary scrutiny. MPs' protests are part of that process, though the final decision rests with the government and Parliament.

What it would not change

• Your existing car. Petrol and diesel cars you already own can still be driven, bought and sold. A softer mandate makes no difference to that. The same applies to the 2030 and 2035 sales dates, which concern new vehicles.
• Your consumer rights. If you buy a car from a dealer, the Consumer Rights Act 2015 still requires goods to be of satisfactory quality, fit for purpose and as described. Policy changes do not alter that.
• Local traffic and parking rules. ULEZ and clean air zone charges, and council parking policies, are set locally under their own legal powers. They do not depend on the national ZEV targets, and councils can keep their own EV-related rules.
• Public charge point regulations. The Public Charge Point Regulations 2023 set requirements such as contactless payment on many chargers, price transparency and reliability standards for rapid chargers. They sit separately from the sales mandate.

Where this meets parking law

A big part of daily EV life is about bays, not policy. Charging bays are covered by the same enforcement rules as other parking:

• Council-run bays are enforced through traffic orders, with penalty charge notices (PCNs) and formal appeal rights.
• Private car parks, such as supermarkets, are enforced through contract, with parking charges that must comply with the Protection of Freedoms Act 2012 if the operator wants to pursue the registered keeper. Appeals go to the operator, then to an independent appeals service if the operator belongs to an accredited trade association.

If you are issued a charge for occupying a charging bay, or for not charging, the signage, terms and whether the charger worked all matter. Our guides on EV charging bay fines in 2026 and why drivers get shock PCNs at chargers go into the detail. This is general information rather than advice on any individual case.

What drivers should know: practical takeaways

Whatever the final shape of the mandate, a few sensible habits apply.

If you are thinking of buying an EV

• Do not rely on headlines to time your purchase. Policy can move, but prices, finance terms and grant eligibility are what you actually pay. Check these on the day.
• Check the Electric Car Grant details. The grant, worth up to £3,750 on eligible models, is separate from the mandate. Eligibility depends on the model, so confirm it before committing. See our guide on which EVs qualify for the UK electric car grant.
• Think about running costs beyond the sticker price. Home charging, public charging, insurance and future road taxes all matter. Our piece on the pay-per-mile tax plans for EVs explains how this part of the picture is changing.

If you are staying with petrol or diesel

• Nothing changes overnight. You can keep driving your current car. Keep an eye on local rules, such as clean air zones and parking charges, which are decided locally and may be more relevant to your costs than national targets.
• Be wary of assumptions about resale value. A softer target does not guarantee that petrol or diesel values will hold or fall. Many factors are involved.

If you rely on public charging

• Photograph everything. If you park in a charging bay, take pictures of the signs, the bay markings and the charger screen, including any fault messages. This evidence can be the difference between a successful and unsuccessful challenge.
• Read the terms. Some bays are for charging only, some limit the time, and some require an app or membership. Rules vary by site.
• Report faulty chargers. Keep a record of when and how you reported the fault. It supports any later appeal.
• Act promptly on notices. Whether it is a council PCN or a private charge, deadlines and discounts for early payment apply, so read the notice carefully and look at the official appeal route. Our guide to private parking charges is a good starting point.

If you drive for work or manage a fleet

• Plan on the basis of total cost of ownership rather than waiting for policy to settle. Our article on UK EV fleet switches stalling as policy wobbles looks at why many businesses are cautious.

Looking ahead

There are a few things worth watching.

The detail. The headline is that the mandate is expected to be weakened, but the real impact depends on which years and which flexibilities change. A softer 2030 target is very different from adjustments to the early years.

Parliament's response. MPs' concerns may lead to debate and pressure, but it is not guaranteed to alter the outcome. Watch how the final proposals are presented and scrutinised.

Industry reaction. Carmakers have lobbied for more flexibility, while others have invested heavily on the basis of the existing timetable. How firms respond, in pricing, model launches and factory plans, will show how much the change matters in practice.

Other levers. If sales targets soften, expect more focus on grants, taxes, charging costs and local policy. For drivers, that means the price signals of running a car, not just the sales rules, may become the main influence on what people buy.

The bottom line: a weaker ZEV mandate is a story about manufacturers' obligations, but its consequences land on drivers through prices, choice and the charging network. Your rights as a driver and a consumer stay the same, and so do the everyday rules on parking and charging bays. Treat the headlines as a prompt to check your own situation, rather than a reason to rush into or put off a decision.
