British Gas EV Power — until recently sold as Electric Drivers — is one of the big-six alternatives to Octopus for EV-specific tariffs. It offers a 5-hour off-peak window from midnight to 5am at 9p/kWh: a penny above Octopus Intelligent Go, two above EDF GoElectric, and the same five hours as Octopus Go. If you're already a British Gas customer or prefer dealing with a larger, more established energy provider, this is a solid option.
Best for: Existing British Gas customers who want an EV tariff without switching provider, or those who prefer a big-six energy company over newer challengers.
How It Works
The tariff provides a simple two-rate structure: a low rate from midnight to 5am for overnight charging, and a standard rate for the rest of the day. Like Octopus Go, there's no smart scheduling — you set your Tesla or charger timer to start at midnight, and it charges at the cheap rate until 5am. The 5-hour window gives you enough time to add roughly 35kWh on a 7kW charger (about 120 miles of range).
Who It Suits
EV Power works well for anyone doing typical daily driving under 120 miles. Five hours is the shortest window in this list — EDF now runs seven — so it suits smaller batteries and steady mileage rather than a Model S run flat. British Gas also offers the Hive smart home ecosystem, so if you're already invested in Hive products, keeping your energy with British Gas keeps everything under one roof.
Cost Breakdown
These figures isolate EV charging electricity. They do not include household use or postcode-dependent standing charges.
| Scenario | Cost per full charge | EV electricity only (10k miles) |
|---|
| British Gas EV Power (9p/kWh) | ~£5.40 | ~£257 |
| Octopus Intelligent Go (8p/kWh) | ~£4.80 | ~£229 |
| Standard variable (~26.11p/kWh) | ~£15.67 | ~£746 |
Compatible Chargers
EV Power works with any charger — just set a timer to activate during the off-peak window. The Ohme Home Pro has direct API integration with British Gas, enabling smarter scheduling similar to its Octopus integration. For a simpler setup, the Tesla Wall Connector with scheduled charging in the Tesla app works perfectly.
