What Q4’s figures show is the UK’s transport energy landscape is no longer moving in step. While domestic electricity prices have ticked upwards, a quieter but more significant shift is underway for electric vehicle business drivers charging at home.

In Q4 2025, the average cost of home charging has fallen again - now to 23p per kWh - marking a gradual but decisive break from the 24-25p range that has held for the past 18 months or so.

The change is subtle, but meaningful. As more drivers switch to EV-specific tariffs offering cheaper off-peak rates, home charging costs are steadily decoupling from the broader domestic energy market.

The numbers tell the story: where the OFGEM average has fluctuated and, in recent months, risen, EV home charging costs have edged down season by season. It’s not a dramatic drop, but across thousands of drivers the cumulative impact is significant for those with a large fleet who can really see the financial impact.

At the same time, costs elsewhere are moving in the opposite direction. Public charging prices are in the high-60s pence per kWh, reinforcing a widening structural gap between those who can charge at home and those who can’t. Petrol and diesel prices have also risen, despite stable global oil markets.

What emerges is a fragmenting market: businesses with EV drivers who have off-street parking are becoming increasingly insulated from any volatility, while others face mounting and often difficult-to-predict costs.
