How OVO Charge Anytime Works
OVO Charge Anytime is a smart EV charging tariff that offers electricity at 14p/kWh — roughly half the standard rate. Unlike fixed-window tariffs, Charge Anytime uses a compatible smart charger to manage when your vehicle charges, typically selecting the cheapest overnight periods.
For home battery owners, this means you can charge your battery overnight at the 14p rate and discharge during the day when standard rates apply. With a spread of around 14p between off-peak and daytime rates, there's meaningful savings potential.
OVO Charge Anytime vs Other Tariffs
How does OVO's offering compare to other UK battery-friendly tariffs?
| Supplier | Tariff | Off-Peak Rate | Off-Peak Window |
|---|---|---|---|
| OVO | Charge Anytime | 14p/kWh | Smart managed |
| Octopus | Go | 7.5p/kWh | 00:30–04:30 |
| British Gas | Battery Tariff | ~12.5p/kWh | 00:00–05:00 |
| EDF | GoElectric | 6.99p/kWh | 23:00–06:00 |
| Scottish Power | EV Saver | 8.5p/kWh | 00:00–05:00 |
Key takeaway: OVO Charge Anytime at 14p/kWh is higher than most competing EV tariffs. However, if you're already with OVO and want to add a battery, you can still achieve meaningful savings. For maximum savings, consider switching to a tariff with a lower off-peak rate.

Why a Battery Can Still Help on OVO at 14p
At 14p/kWh, OVO is no longer the cheapest off-peak rate in the UK — but the spread vs OVO's standard daytime price is still around 17p. Each kWh your battery shifts from daytime to off-peak is worth roughly that gap, but what you actually save depends on how much of your usage the battery can supply. The headline you should care about isn't the off-peak rate in isolation — it's the gap. Use the calculator for an estimate based on your own usage.
Frequently Asked Questions
What happened to OVO's 7p/kWh rate?
OVO originally launched Charge Anytime at 7p/kWh but increased it to 14p/kWh in November 2024. Volvo customers charging through the Volvo Cars app may still access a 7p/kWh partnership rate on eligible models.
Can I use Charge Anytime with a home battery?
Charge Anytime is designed for EV smart chargers. However, if you're an OVO customer, the overnight charging pattern also benefits home battery storage — you set your battery to charge during cheap overnight hours and discharge during the day.
Is OVO a good supplier for battery owners?
OVO is the UK's 2nd largest energy supplier, offering reliable service and 100% renewable electricity. While their 14p off-peak rate isn't the cheapest, OVO customers already committed to the supplier can still benefit from adding a home battery.
