How the EDF GoElectric Tariff Works
EDF GoElectric is a time-of-use electricity tariff designed for EV owners, but it works equally well for home battery storage. During the off-peak window, you pay a significantly reduced rate for electricity — as low as 6.49p/kWh on the GoElectric 35 tariff.
By pairing this tariff with an plug-in home battery, you can automatically charge overnight at the cheap rate and use that stored energy to run appliances plugged into the battery during the day — effectively reducing the cost of a significant portion of your electricity usage by up to 77%.
GoElectric vs GoElectric 35 — Which Is Better?
EDF offers two GoElectric tariff tiers:
| Feature | GoElectric | GoElectric 35 |
|---|---|---|
| Off-peak rate | 6.99p/kWh | 6.49p/kWh |
| Off-peak window | 23:00–06:00 (7 hours) | 23:00–06:00 (7 hours) |
| Best for | Budget-conscious battery owners | Maximum savings — more charge time |
| Daytime rate | ~28–29p/kWh (varies by region) | ~28–29p/kWh (varies by region) |
| Smart Charging | Not included | Included — auto EV charging |
Tip: GoElectric 35 offers a lower off-peak rate (6.49p vs 6.99p) over the same 7-hour 11pm–6am window. For battery owners, that means the same charging time at a slightly lower cost. Run both options in our calculator above to see the difference.
Why EDF GoElectric Is Great for Batteries
EDF's electricity supply is backed by nuclear and renewable generation, making it one of the lower-carbon options available. Combined with the competitive off-peak rates, it's an excellent choice for environmentally conscious homeowners who want to maximise their battery savings.
The GoElectric 35 tariff's 7-hour off-peak window (11pm–6am) is particularly generous — even the larger 15.36 kWh plug-in home battery can be fully charged from empty within this window at the 2.2 kW charge rate.
Why our plug-in batteries Fits EDF GoElectric 35's 7-Hour Window
GoElectric 35's 23:00–06:00 window is 7 hours wide — just long enough to fully charge the largest 15.36 kWh battery stack (~7 hours) at the 2.2 kW charge rate. In practice that means you can run your battery cycle slightly conservatively (avoiding pushing the cells to 100% every night) and still cover ~80–90% of an average household's daytime consumption from off-peak electricity. That's the difference between a 4-year and a 6-year payback at typical EDF regional rates.
Frequently Asked Questions
Do I need an EV for the GoElectric tariff?
Yes, EDF requires you to own or lease a plug-in electric vehicle to be eligible for GoElectric tariffs. However, if you have an EV and a home battery, both can benefit from the cheap overnight rate.
Do I need a smart meter?
Yes, a SMETS2 smart meter is required for the GoElectric tariff. If you don't have one, EDF can arrange a free installation.
Is the off-peak rate fixed?
GoElectric is a fixed-rate tariff, so your rates are locked in for the duration of your contract. This gives you certainty about your savings, unlike variable tariffs that can change with notice.
Using plug-in solar with EDF
Plug-in solar has been legal in Great Britain since 27 August 2026 for compliant kits up to 800 W. It works with any electricity supplier, including EDF: you don't need your supplier's permission, only a free notification to your network operator within 28 days. The electricity it makes cuts what you buy at your normal unit rate.
Payment for any electricity you export depends on your export tariff.
