What happens if you switch energy supplier after installing its EV charger?

The part most likely to change is the tariff-linked control, not the physical charging equipment. Before switching, check who owns the charger, which app controls it and whether its cheaper charging sessions depend on your current supplier.

If you bought the charger outright, it will usually remain available after you move to another supplier. You may still be able to start and stop charging from the charger, the vehicle or its existing app. Some functions can depend on an online account, so keep the login details and read the charger’s terms before closing the old energy account.

If the charger came with an energy tariff or subscription, the agreement may contain different conditions. The supplier might have provided the equipment at a reduced cost, included it within a minimum-term package or linked it to a particular smart-charging service. Check whether you need to keep paying for the charger, repay an installation contribution or give notice before changing supplier.

The physical installation does not normally need removing. However, the agreement determines what happens to the associated service. Your supplier should explain this in the charger, tariff or subscription terms rather than leaving you to assume that every feature will transfer automatically.

Smart charging may work differently after the switch. A supplier’s app can use your tariff, meter data and vehicle settings to choose when charging starts. If you leave that supplier, the app may stop scheduling sessions, lose access to your account or revert to basic charging. A new supplier may offer its own smart-charging feature, but it may only support particular chargers, vehicles or tariffs.

That does not necessarily prevent you from charging the car. It means you may need to use the charger’s controls or the vehicle’s timer instead of the old supplier’s automatic schedule. Check how the charger behaves if its internet connection or supplier account is unavailable, particularly if you rely on scheduled charging overnight.

Check these points before you switch:

• Find out whether you own the charger or use it under a separate supplier agreement.
• Read the terms for minimum periods, remaining payments, cancellation charges and equipment ownership.
• Record the charger model, serial number, app name and account details.
• Check whether the charger has a separate warranty or service contract.
• Save any charging history, schedules and settings you may want to keep.
• Ask the new supplier whether its tariff supports your charger and vehicle.
• Confirm how charging will be controlled if the old supplier’s app is closed.

Take screenshots of the current schedules and tariff settings before the old account ends. If the charger uses a separate manufacturer app, keep that account active unless its terms say otherwise. Deleting the energy account and deleting the charger account may be two different actions.

After the switch, check the charger at the next planned charging session. Confirm that the car starts charging, the schedule still operates and the new tariff records the session correctly. If the old app no longer controls the charger, remove its access only after you have confirmed that the replacement controls work.

A change of supplier can also affect the way charging costs appear on your bill. A smart tariff may require half-hourly meter data, a particular consent arrangement or an active supplier account. If those conditions are not met, charging may continue but the supplier may bill it under the standard electricity arrangement instead.

If the charger stops responding, first check whether the problem affects the charger itself or only the supplier’s app. The charger display, vehicle controls and electrical supply can help identify the difference. Do not reset the unit or change wiring until you have checked the warranty and installation terms.

Where the change involves settings, connectivity or electrical work, we can assess the installation and explain what can remain in place. Our NICEIC-registered electricians can check the charger, its protective equipment and the control arrangement without assuming that a new tariff requires a new charger.

The safest approach is to treat the charger, the energy tariff and the smart service as three related but separate parts. Confirm what happens to each one before you switch, then test a complete charging session afterwards.
