The Impact of Global Energy Markets
The global energy market is currently experiencing significant instability, largely due to ongoing tensions in the Strait of Hormuz. Because this region acts as a critical chokepoint for approximately 20% of the world’s oil and liquid gas supply, recent restrictions have created a “rollercoaster” effect on wholesale energy costs.
As these global wholesale costs shift, electricity pricing in the UK is directly impacted. Consequently, Octopus Energy has had to adjust its rates to reflect these market realities.

What This Means for Your EV Charging
From 1 May, the off-peak rate for Intelligent Octopus Go will move to 6.9p/kWh.
While any increase is unwelcome, it is important to put this into perspective. Even with this adjustment, Intelligent Octopus Go remains one of Britain’s most competitive standalone EV smart-charging rates. When compared to the rising costs facing petrol and diesel drivers—who are seeing significant spikes every time they visit the fuel pump—the impact on your household running costs remains minimal.
For a typical 40kWh charge, this adjustment equates to just pennies, ensuring that driving electric remains far more cost-effective than sticking with a combustion engine vehicle.
