AllCosts report 2025
June
All the data and costs for running electric, petrol and diesel business cars and vans, in Allstar’s AllCosts report. In this latest update, we reveal June’s figures, and their impact on your business.
Data from June 2025

One of the most remarkable things has happened in the last month – something that hasn’t occurred in all the time we’ve been reporting electricity and fuel prices through AllCosts. In June, the average price for domestic charging, public charging, diesel and petrol have all stayed exactly the same.
Considering that energy prices are usually heavily influenced by geopolitical events (albeit with the caveat that there can be a time lag before the consumer feels the effect), then May and June were especially tumultuous.
Attacks on Iran’s nuclear facilities and the resultant reprisals threatened oil supplies. The US's ongoing tariff negotiations destabilised the established trading order and there are still no signs of scaling back the war on Ukraine.
Oil prices swung by nearly $20 at the height of the conflict between Israel and Iran, with the result that analysts lifted their oil price forecasts slightly, but rising supply and continued lower demand acted as a counterbalance.
The consequence is that oil prices have overall - maybe even surprisingly - remained steady, which is why we are seeing the cost of petrol and diesel stay the same.
As for electricity, a hot sunny, but windy early Summer has seen the UK’s zero carbon power production network at its most effective.
According to the National Energy System Operator in June, wind energy was the leading source of electricity generation. It contributed 31% of the total energy mix, its highest share for the past five years, while zero-carbon sources (wind, solar and nuclear) accounted for 61% of the electricity mix overall, peaking at 87% early in the month.
Generally, these sources provide cheaper energy than gas powered production, which helps to keep prices down at the chargepoint.
All this is good news for businesses running vehicles, because stability allows them to plan and budget far more accurately. Charging at home continues to be by far the most stable energy source price-wise, with the average of 24p remaining steady for eight months.
Public charging has seen the biggest drop in price during that time, from a height of 77p down to 65p now, although some of this is down to ever wider mix of providers.
Petrol and diesel prices have both only moved within a 7p per litre window during this period too, meaning few unpleasant financial shocks for fleets.
The question is: how long will these positive pricing trends continue? Some major political events have failed to move the dial markedly in recent times, so we can hope for continued stability for some time to come.
