UK to ease ZEV mandate for 2027-2035 — but only at the margins

The UK government will adjust electric vehicle sales targets for the 2027-2035 period, but the package emerging from consultation will be smaller in scope than the auto industry had sought.

That is the clearest signal from the review of the Zero Emission Vehicle (ZEV) mandate. Officials opened the review earlier in 2026. They have since indicated a willingness to recalibrate the trajectory of the mandate. The eight-year compliance window under negotiation now defines the policy fight.

What does the ZEV mandate cover?

The mandate sets annual zero-emission sales shares for every automaker selling new cars in the UK. It runs to 2030, the year new combustion-only vehicles are scheduled to leave showrooms. The 2027-2035 review window covers the final run-up to that ban. It also captures the first five years of post-ban compliance trading between credit buyers and sellers.

What did industry push for?

Carmakers, dealers and industry groups submitted evidence during the consultation phase. Their submissions pressed for softer annual percentages. They asked for expanded credit-trading flexibility between manufacturers. They requested longer compliance horizons to spread investment across more model cycles. Early coverage suggested ministers were open to significant movement on all three fronts.

How much will actually change?

The headline answer, drawn from the review's emerging shape: less than first reported. According to consultation feedback reported in the review, the policy will be "less watered-down than initially thought." That phrasing reflects a tightening of the revision package inside government, not a widening of it.

No revised statutory instrument has been published. No new annual percentage has been confirmed. No Treasury movement on the vehicle excise duty differential between EVs and combustion cars has been signalled. Each of these gaps is itself a story for manufacturers planning UK model launches through 2030.

Which OEMs face the largest exposure?

Every brand selling new cars in the UK market falls inside the mandate. Nissan's UK lineup, including the Ariya crossover, sits inside this regulatory perimeter. For any manufacturer whose 2027 mix depends on purchased credits rather than delivered EVs, exposure compounds quickly. A small percentage shift moves revenue by large sums at fleet level.

What remains unsaid

The review documents do not name which annual percentages will move. They do not say which compliance flexibilities will be granted. They do not confirm whether the 2030 endpoint itself is up for negotiation. Each silence is a tell. Each gap leaves room for a second round of lobbying before any statutory instrument is laid.

What to watch next

• The Department for Transport's formal consultation response, expected later in 2026.
• The opening of the 2027 compliance year, the first live test of any revised glidepath.
• Any Treasury intervention on vehicle excise duty, which sets the demand-side price signal for EV uptake.
• Any further movement on the 2030 endpoint, the single hard number anchoring the policy.

Until the percentage within the eight-year window moves on paper, the UK's EV transition policy remains closer to a managed retreat than a regulatory revolution.
