Which EV tariff is best for a Tesla?

Octopus Intelligent Go is the default managed-charging choice because an eligible Tesla can connect through the vehicle rather than a particular wallbox. EDF GoElectric is cheaper on the fixed overnight rate if you are happy to schedule charging yourself.

Do I need a special charger for an EV tariff?

Not for a fixed-window tariff. Any reliably scheduled car or charger can use the published cheap hours. Managed products need a compatible EV or charger so the supplier can control and measure eligible charging.

Does the cheap EV rate apply to the whole house?

It depends on the product. Fixed time-of-use tariffs usually apply the lower meter rate to household electricity in the window. Managed add-ons can credit only eligible EV charging. Check the live supplier terms before moving appliances into a charging slot.

Hours and control

Cheap hours and charging control are different things.

Fixed cheap hours

The tariff sets the cheap window. Your car or charger schedules charging within it.

Managed charging

The supplier schedules eligible charging through a compatible car or charger. Discounted-energy rules depend on the product.

Choose by constraint

The best tariff depends on what you are willing to manage.

Start with the routine, then compare the bill. A cheap rate that the car repeatedly misses is not the cheapest tariff in practice.

Compatibility and scheduling

See who controls charging on each tariff.

The point is not a promise of savings. It is a visible summary of whether the supplier, the charger or the vehicle controls the schedule, and what compatible setup the tariff expects.
