ScottishPower EV Saver Review 2026

ScottishPower EV Saver charges 7.7p/kWh from 2am to 5am and a day rate averaging 29.02p/kWh, the lowest of the two-rate EV tariffs we track. The catch is the window: three cheap hours a night, the shortest of any EV tariff we cover.

This review covers how EV Saver works, what it costs, and the drivers it does and doesn’t suit.

How EV Saver works

EV Saver is a fixed, electricity-only time-of-use tariff. The current version, EV Saver Oct 27 v1, is fixed until October 2027. As on other two-rate EV tariffs, the cheap rate applies to all the electricity your home uses from 2am to 5am, and the day rate applies at all other times.

There are no smart charging slots. You set your car or charger to start charging at 2am, and any home charger works. You need a smart meter that sends half-hourly readings so ScottishPower can bill the two rates separately. The tariff also includes a one-year Zoom EV subscription.

Is three hours enough?

A 7kW home charger adds about 21kWh in three hours, roughly 70 miles of driving in a car that does 3.5 miles per kWh. A driver covering 10,000 miles a year needs about 2,857kWh, or around 8kWh a night, so plugging in most nights fits comfortably. At 7.7p/kWh against the October 2026 price cap average of 26.32p/kWh, that driver would save roughly £530 a year on charging.

Three hours is not enough to fill a large battery from low in one night. If you drive long distances, or prefer to charge once or twice a week, a longer window will suit you better: EDF GoElectric gives you seven hours at 6.66p/kWh, and E.ON Next Drive Smart six hours plus smart charging slots at 8.1p/kWh.

The day rate advantage

Most EV tariffs balance a cheap night rate with a high day rate. EV Saver’s 29.02p/kWh average day rate is the lowest of the two-rate EV tariffs we track, below E.ON Next Drive Smart (30.82p), EDF GoElectric (35.21p) and Intelligent Octopus Go (36.70p). That matters more here than on other tariffs, because 21 hours of every day are charged at the day rate.

EV Optimise for existing customers

If you are already with ScottishPower, it also offers EV Optimise, an add-on that charges a compatible car at 7.22p/kWh at any time while the rest of your home stays on your normal tariff. It is not compatible with every car and charger, so check ScottishPower’s list before choosing it.

Our verdict on ScottishPower EV Saver

EV Saver combines a low overnight rate with the lowest day rate of the two-rate EV tariffs we track, which makes it a good fit for lower-mileage drivers who plug in every night and homes that use a lot of electricity during the day. The three-hour window is a real limitation for high-mileage drivers, and the standing charge only appears in a quote, so compare your full annual cost before switching.
