How much does public EV charging cost in Northern Ireland in 2026? ESB prices explained
At ESB chargers, contactless high-power charging is 75p/kWh from July 2026, while members pay 70p/kWh plus a £4.99 monthly subscription.
Public charging cost can make or break the running-cost case for an electric car, particularly for drivers who cannot plug in at home. ESB's Northern Ireland prices changed from 1 July 2026, with separate rates for members, pay-as-you-go users and contactless charging.
For rapid and high-power DC chargers rated at 50kW and above, the published Northern Ireland rates are 70p/kWh for members, 74p/kWh on pay as you go and 75p/kWh by contactless one-time payment. Membership costs £4.99 per month and has a 12-month minimum term.
What does a 50kWh charge cost?
At 75p/kWh, adding 50kWh costs £37.50 before any overstay charge. At the 70p member rate, the same energy costs £35.00, excluding the monthly membership fee.
The real cost per mile depends on the vehicle's efficiency. An EV using 18kWh per 100 miles would use £13.50 of electricity per 100 miles at a 75p/kWh charger. A more efficient or less efficient car changes that figure significantly.
What about slower ESB charging?
For the network's lower-power category, ESB lists 57p/kWh for members, 60p/kWh for pay-as-you-go and 61p/kWh for contactless. The naming can be confusing because ESB's NI price table describes this category as AC/fast charging up to 50kW; always check the individual charger in the app or on the unit.
When does membership pay for itself?
On high-power charging, membership saves 5p/kWh against contactless. Ignoring other differences, a driver would need to buy roughly 100kWh a month for that 5p saving to cover a £4.99 monthly fee. Compared with the 74p pay-as-you-go rate, the saving is smaller.
That is only a rough break-even calculation. Drivers should compare the full plan terms, minimum term and their actual charging pattern.
What is the overstay fee?
ESB lists an overstay charge of 50p per minute after 45 minutes on rapid and high-power chargers, capped at £22.50. On the lower-power category, the fee applies after 10 hours. The purpose is to discourage cars from occupying a charger after a reasonable charging period.
Why public charging can be much dearer than home charging
Rapid-charging hardware, grid connections, maintenance and site costs are reflected in public prices. A driver who can charge most energy at home can therefore have very different EV running costs from someone who depends almost entirely on public DC charging.
Should you compare EV charging with petrol by pence per mile?
Yes. Comparing 75p/kWh with a petrol price per litre is not intuitive. Convert both to cost per mile using the actual efficiency of the cars being compared. For an EV, use miles per kWh or kWh per 100 miles. For petrol or diesel, use real mpg rather than a best-case brochure number.
Check the live charger before plugging in
Networks can update tariffs, and individual third-party chargers shown in an app may have different prices. The figures here reflect ESB's Northern Ireland pricing published for July 2026. Check the live price displayed in the charging app or payment flow before starting a session.
