Why New Electric Cars Are £11,000 Cheaper Right Now (and How Long That Lasts)

• UK car manufacturers spent more than £5 billion discounting electric cars last year, an average of £11,000 off each one, to avoid £12,000-per-car fines for missing government sales targets.
• The rule behind the discounts, the ZEV mandate, requires 33 percent of new cars sold this year to be zero-emission, rising to 38 percent in 2027, and no manufacturer has yet been fined for missing it.
• The government opened a consultation in August on relaxing those targets, which could mean the current scale of EV discounting does not last much longer.

The Discount Behind Every Cheap EV Advert

If a new electric car has looked unusually good value this year, that is not an accident of the market. It is manufacturers paying to avoid a fine. UK car makers discounted electric models by more than £5 billion in total last year, an average of £11,000 off each car sold, according to industry analysis of the sums manufacturers are spending to hit government sales targets rather than pay the penalty for missing them.

What the ZEV Mandate Actually Requires

The Zero Emission Vehicle mandate requires that 33 percent of the new cars each manufacturer sells in the UK this year are fully electric, rising to 38 percent in 2027 and climbing further after that on the way to an eventual ban on new pure petrol and diesel car sales. Manufacturers that fall short face a fine of £12,000 for every non-compliant car above their allowance, a figure steep enough that most manufacturers have chosen to discount electric models heavily instead, effectively buying their way to the target rather than risking the penalty. Manufacturers can also buy compliance credits from rivals who have exceeded their own targets, spreading the cost around the industry rather than paying the government directly.

So far, the strategy has worked for the manufacturers. No car maker has actually been fined for missing the mandate in either 2024 or 2025, as discounting, credit trading and shifting sales mix toward electric models have kept every major manufacturer compliant, if only just, in both years.

Buyers Are the Ones Benefiting, for Now

None of this pressure is visible to a buyer walking onto a forecourt. What they see instead is a really large discount on a new electric car, often disguised as a manufacturer contribution, a deposit top-up or an unusually generous part-exchange valuation rather than a simple price cut. Registration data backs up how effective this has been at shifting metal. Battery electric vehicles accounted for 29.8 percent of new car registrations in August, up 27.7 percent year on year, with private buyer demand up 19 percent on the same month last year. Manufacturers under the most pressure to hit their individual targets tend to discount the hardest, which means the size of the deal on offer can vary sharply between brands even on in the same way priced electric cars.

Why the Discounts Might Not Last

In August, the government opened a new consultation reviewing whether the ZEV mandate’s targets should be relaxed, after sustained pressure from manufacturers over the cost of compliance and the pace of the delivery timeline. If ministers water down the annual percentage requirements, or push the toughest targets further into the future, manufacturers lose much of their incentive to discount as aggressively as they have over the past two years. That would not make electric cars more expensive overnight, but it removes the regulatory pressure that has been quietly subsidising EV buyers, and discounts driven by panic to hit a legal target tend to shrink fast once that pressure eases.

What This Means If You Are Considering an EV

If you are already planning to buy an electric car, this year’s registration plate change is a reasonable moment to ask a dealer directly how much of the price is a manufacturer contribution tied to compliance targets, as that is often the most negotiable part of the deal. Get quotes from more than one brand, as the size of the discount depends heavily on how close that specific manufacturer is to its own ZEV mandate target this year, not on the underlying value of the car. Dealer offers and real transaction prices can differ by well over a thousand pounds even before any EV-specific discount is applied, so it is worth checking the real market price of any car you are quoted on before agreeing a figure.

It is also worth remembering that a heavily discounted new price does not always translate into strong resale value a few years down the line. Some of the electric cars offering the biggest upfront savings have also shown some of the steepest depreciation, so it is worth balancing the discount against what the car is likely to be worth when you come to sell or part-exchange it.

Why Some Brands Discount Harder Than Others

Not every manufacturer sits in the same position under the mandate. A brand that sells a wide range of electric models across several price points can usually spread its compliance across many cars, keeping individual discounts modest. A manufacturer that still leans heavily on petrol and diesel models, or that only recently launched its first mainstream electric car, has far less room to manoeuvre and has to push individual EV discounts much harder to hit the same 33 percent threshold. This is why two electric cars that look in the same way priced and specified on paper can carry noticeably different discounts depending purely on which manufacturer is under more pressure this particular year, rather than anything to do with the car itself. Buyers who assume every EV deal reflects the same underlying value are often missing where the real bargains, and the real markups, actually sit.

Chinese Manufacturers Are Changing the Maths

The arrival of Chinese brands such as MG, BYD, GWM ORA and Omoda has added a further complication for established manufacturers trying to hit their targets. These brands often enter the UK market with electric models priced aggressively from the outset, without needing the same scale of compliance-driven discounting that legacy manufacturers rely on, as their electric ranges already make up a larger share of what they sell everywhere. That puts additional competitive pressure on established brands, who now have to discount not just to satisfy the regulator but to compete on price with rivals that were never as exposed to the mandate’s targets in the same way.

The Bigger Imagine

The ZEV mandate was designed to force a shift in what manufacturers sell, not what buyers pay, but in practice the two have become closely linked. Every pound a manufacturer spends discounting an electric car to hit its target is a pound it is not spending elsewhere, and industry figures have warned that the scale of discounting seen over the past two years is not lasting for long without either government support or a change to the targets themselves. For buyers, that makes the current window a really unusual one: a large, policy-driven discount that exists as of a regulation under active review, rather than as of ordinary market competition.

A trade-in or part-exchange offer that looks generous can also be doing some of the same job as a headline discount, quietly helping a manufacturer hit its electric sales percentage without cutting the advertised price itself. Reading the breakdown of any deal line by line, rather than judging it purely on the final monthly payment, is the only reliable way to see how much of the saving is really coming out of the manufacturer’s compliance budget.

Whatever ministers decide once the consultation closes, the window to benefit from today’s compliance-driven pricing is open now, not for long.
