UK stats are different: https://www.zap-map.com/ev-stats/ev-market , possibly due to the shorter max travel distances.

> As of the end of June 2025, there were 2,450,462 plug-in cars, with over 1,585,000 battery-electric cars and nearly 865,000 PHEVs, registered in the UK.

> There are more fully electric cars than there are plug-in hybrids on UK roads and the gap has been widening. In 2021, fully electric cars accounted for 60% of all plug-in cars but with the increase in options, range and popularity of fully electric cars, and by May 2025 this has increased to 65%.

(That stat does exclude non-pluggable-hybrids, but those are kind of pointless stalling of the transition off petrol)
