💡 Why I Use the Tesla Granny Charger Instead of a Wallbox
I charge my Model 3 Long Range overnight using the official Tesla Mobile Connector (granny charger) at 2.5kW on Octopus Intelligent Go. Because it charges slowly, Octopus can stretch the session well beyond the standard cheap window – which means more of my household energy (dishwasher, washing machine) also runs at around 7p/kWh. The result is about £20 a month for roughly 300kWh. I've never felt the need to upgrade to a faster wallbox: for daily home charging on Intelligent Go, the granny charger actually works in my favour.

If you’ve switched to Octopus Go for your home EV charging, you’re already on track to save money by charging your car overnight at just 7.5p per kWh. But to get the most from your tariff, the right home charger makes a big difference.

So, what’s the best home charger for Octopus Go? Here’s what you need to know.
Why Your Charger Choice Matters
Octopus Go gives you four hours of super-cheap electricity every night (from 11.30pm to 3.30am). That means your charger needs to be:
- Smart-schedule compatible (so it can charge only during the cheap rate)
- Fast enough to get a good chunk of your battery filled overnight
- App-connected for monitoring and flexibility
- Compatible with Octopus smart charging features if you want hands-off automation
Best EV Chargers for Octopus Go
1. Ohme Home Pro
Ohme is the most seamless option for Octopus customers. It integrates directly with Octopus Go and the Intelligent Octopus tariff, giving full automation.
Why it’s great:
- Octopus certified
- Automatically charges when rates are cheapest
- In-app cost tracking
- Tethered 5m Type 2 cable
2. Hypervolt Home 3 Pro
Hypervolt’s British-built charger is smart, stylish and packed with features.
Why it’s great:
- Fully compatible with Octopus Go
- Free app for scheduling and monitoring
- Solar integration support
- Built-in load management
3. Tesla Wall Connector
If you drive a Tesla, this is a strong contender. While the charger doesn’t directly integrate with Octopus Go, Octopus connects to the car directly to start and stop charging.
However, there’s a key limitation worth noting. Octopus doesn’t control the Tesla charger – it controls the car itself through the Octopus app. And the app only supports one Tesla per account. So, if you have multiple Teslas and more than one Wall Connector, only one car can be controlled through Intelligent Octopus Go. This setup can cause issues for families with multiple Teslas, making the Tesla Wall Connector less ideal for multi-vehicle households.
Slower Charging Can Be Smarter
Oddly enough, slower chargers (like a 3kW granny charger) can sometimes help you benefit beyond the four-hour window. Octopus’ Intelligent Go scheduling occasionally lets slower chargers run longer outside peak times, which means:
- Longer charging sessions
- More household energy (like dishwasher cycles) at the 7.5p/kWh rate
This can make a basic charger surprisingly useful when combined with smart scheduling.
Our Pick? Go with Ohme for Hassle-Free Integration
If you want a charger that just works with Octopus Go (and especially Intelligent Go), Ohme Home Pro is the clear winner. You won’t need to worry about setting timers or fiddling with apps. Just plug in, and it charges when energy is cheapest.
Final Tip: Pair With a Smart Tariff
If you’re not already on Octopus Go, now’s the time. You’ll need a smart meter to join, and once you’re set up, you’ll unlock some of the cheapest EV charging rates in the UK.
