START WITH YOUR HOME
Your postcode comes first.
Enter a full postcode to see available regional prices. Without it, you are browsing supplier information, not a price for your home. Covers Great Britain; Northern Ireland has a separate market.
A smart meter must communicate with the supplier and provide the required half-hourly readings. SEG can also accept a suitable half-hourly export meter; check each supplier’s terms.
All listed products reviewed: 01/11/2026. Supplier rates, eligibility and availability checked. Conflicting supplier prices are flagged; postcode API checks have their own timestamps.
Whole home or just the car?
A time-of-use tariff usually prices the whole home by time. Device-based add-ons use charging credits or separate plans; household consumption stays on your underlying tariff.
Know how fresh the price is
Postcode checks request available public APIs directly. Each product shows its rate source and check date. Where no verified public API is integrated, supplier pages and quotes are the source.

EV import tariffs & charging add-ons
Compare what you buy: off-peak charging, the rest-of-day rate and daily standing charge. A charging add-on may apply only to the car.
UNDERSTAND THE DETAILS
What to know before choosing.
Fixed cheap windows
A fixed overnight window is easy to understand and can reduce the cost of the whole home during those hours. Check whether the period is long enough for the mileage you need.
Smart or managed charging
The supplier schedules a compatible car or charger around grid conditions, often adding charging slots. Compatibility and app connectivity are central.
EV tariff + home battery
A whole-home cheap window can charge both, but supplier-controlled products may limit other automation. Check the normal daytime rate as well as the headline EV price.
What does 7p/kWh cost per mile?
At 3.5 miles/kWh, 7p electricity is about 2p per mile before charging losses. Use the calculator above with your own efficiency and mileage.
