A Tale of Two Policies: The Grant vs. The Mandate

The UK’s electric vehicle strategy in 2025 is a tale of two policies working in tandem, and sometimes at odds: the consumer-facing grant and the industry-facing mandate. September’s record sales were the direct result of their powerful, if complex, interaction.
The first policy, the grant, is the “carrot.” It’s a sweet, attractive incentive designed to lure consumers towards electric vehicles. By offering up to £3,750, it makes the choice to go electric easier and more appealing. Its effect is direct, immediate, and populist—it visibly helps people buy new cars. The September sales surge, with EVs up by nearly a third, is the grant’s triumphant story.
The second policy, the ZEV mandate, is the “stick.” It’s a regulatory tool that forces manufacturers to sell an increasing percentage of electric vehicles, with a headline target of 28% this year. Its purpose is to ensure supply and to push the industry, sometimes against its will, towards a zero-emission future. It works behind the scenes, shaping corporate strategy rather than consumer choice.
In an ideal world, the carrot and the stick work together harmoniously. The mandate forces manufacturers to supply the cars, and the grant helps consumers to buy them. For a moment, in September, this seemed to be happening perfectly.
However, the tale has a twist. Just as the carrot was made sweeter with the grant’s reintroduction, the stick was made softer. The mandate was weakened with “flexibilities,” making it easier for the industry to comply. So, while the government was using one policy to pull consumers forward, it was using another to ease the push on producers. This duality lies at the heart of the UK’s complicated and sometimes contradictory path towards an electric future.
