Scottish Power EV Saver rounds out the big-six EV tariff offerings with a 5-hour off-peak window from midnight to 5am at 8.5p/kWh. Scottish Power's electricity comes from 100% renewable sources (primarily wind), so if you're in Scotland or care about supporting UK wind energy, this tariff aligns your EV charging with your environmental values.
Best for: EV owners who want 100% renewable electricity and are already with Scottish Power, particularly those in Scotland or areas it serves.
How It Works
EV Saver follows the standard time-of-use model: a 5-hour off-peak window from midnight to 5am at the reduced rate, and a standard rate for the rest of the day. No smart features, no charger restrictions — set your timer and charge overnight.
Who It Suits
This tariff is a natural fit for Scottish Power customers who want to add an EV to their energy plan without switching providers. The rate matches Octopus Go exactly and sits 1.5p above EDF GoElectric, which also runs two hours longer. The 100% renewable claim is backed by Scottish Power's significant wind portfolio. If you're already a Scottish Power customer, adding EV Saver is the path of least resistance — but it is not the cheapest way to charge a car.
