The plummet as reported compares the final months of sales that benefited from the clean car discount against 1 month of sales after the discount was scrapped. Hardly surprising there's a large difference - savvy buyers swooped in and purchased an EV before their price went up overnight. As others have mentioned, changes to road user charges are another part of the new government's changes. EVs now pay a road user charge whereas previously they did not. This was a secondary subsidy to further incentivise EV uptake and EV owners understood that it was always going to be a temporary exemption. (The government plans to standardise road user charges across all vehicle types. Currently ICEs pay no direct road user charges and instead pay taxes on fuel.) So there's a bit of double whammy here and it's hardly surprising that EV sales are experiencing a dip. But once road user charges are standardised and more and cheaper EV options become available (as they are all the time) I expect EV sales to bounce back and continue to increase as a percentage of car sales.
