Believ, the electric vehicle (EV) charge point operator (CPO), has written to No.10 Downing Street urging the Government to maintain the ZEV Mandate in its current form, warning that policy uncertainty risks slowing private investment in public charging infrastructure and delaying rollout in higher-cost and rural areas.

The CPO says the Mandate has underpinned investor confidence in the EV charging sector, enabling long-term capital allocation and large-scale deployment planning. It warns that further changes or weakening of targets could increase the cost of capital and slow delivery of infrastructure outside major urban centres.

With more than two million EVs already on UK roads, Believ says the market requires long-term certainty to support continued expansion of charging infrastructure. It argues the Mandate remains a foundation for private investment, supporting economic growth, job creation, energy security and the UK’s wider transition to electric transport.

Believ has committed more than £300 million to public charging infrastructure and says stable policy is essential to sustaining investment at scale across the sector. It warns that continued policy shifts could risk uneven rollout and reduce access to charging in less commercially viable locations.

Guy Bartlett, CEO of Believ, said: “The ZEV Mandate gives industry the long-term confidence needed to invest, build and deliver at scale. Weakening it now would risk slowing infrastructure rollout at the very moment private investment is accelerating.

“The UK has a real opportunity to strengthen its position as a stable, investable market for EV infrastructure. Alongside maintaining the Mandate, complementary measures such as reducing charging costs can help support demand and make the transition easier for drivers.”
