If you have recently made the switch to an electric vehicle: or you are seriously crunching the numbers before taking the plunge: you have likely heard whispers about the savings on offer from Octopus Energy. Mentioned by EV drivers on nearly every forum, tariffs like Intelligent Octopus Go are practically legendary for turning nighttime vehicle charging into pocket change.
However, getting your hands on those headline-grabbing rates requires more than just switching energy suppliers. To unlock the absolute lowest pence-per-kWh rates, your home needs the right hardware working seamlessly in the background. Here at EV Power Point, operating from our roots in Worcestershire, Warwickshire, and the West Midlands while helping drivers nationwide, we talk homeowners through this exact setup every single day.
In this guide, we will break down how Octopus Energy EV charging tariffs work, why a smart 7kW home charger is your ultimate secret weapon, and how a professional electric car charger installation gets you plugged into the cheapest rates possible.
Understanding Octopus Energy EV Tariffs: Go vs. Intelligent Go
Before diving into hardware, it helps to understand what you are plugging into. Octopus Energy currently offers two standout tariffs tailored specifically for electric vehicle owners:
- Intelligent Octopus Go: This is the crown jewel of EV tariffs. It offers an incredible headline rate of around 8p per kWh overnight for both your EV and your entire household. The catch? It relies on smart integration. Octopus communicates directly with your compatible car or smart home charger, automatically scheduling your charging sessions during the cheapest, greenest slots overnight (typically a guaranteed 11:30 pm to 5:30 am window for whole-home usage, plus extra smart-scheduled slots).
- Octopus Go: The original favorite. This simpler tariff gives you a fixed 5-hour off-peak window every night (usually from 00:30 to 05:30) where your electricity drops to roughly 7p to 9p per kWh. It does not require smart control from Octopus; you simply program your charger or car to run during those hours.
| Tariff | Smart Control by Octopus | Typical Overnight Rate | Cheap Window for Whole Home | Works with Smart Charger? | Best For |
|---|---|---|---|---|---|
| Intelligent Octopus Go | Yes (Automated scheduling) | ~8p / kWh | 11:30 PM – 5:30 AM (plus smart slots) | Yes (Required or compatible car) | Maximum savings and hands-off automation |
| Octopus Go | No (Manual scheduling) | ~7p–9p / kWh | 5-hour fixed window (e.g., 00:30–05:30) | Yes (Optional smart features) | Drivers wanting a predictable, fixed schedule |

Why a Smart 7kW Home Charger is Your Secret Weapon
While you can technically charge on Octopus Go using a standard 3-pin plug or a basic charger, doing so is painfully slow and inefficient. A standard 3-pin plug delivers roughly 2.3kW, taking well over 24 hours to fill a modern EV battery.
This is where a dedicated home ev charger installation changes the game. By installing a fast 7kW smart charger, you triple your charging speed, replenishing your battery from empty to full in roughly 6 to 8 hours: comfortably inside those cheap overnight windows.
More importantly, if you want to access Intelligent Octopus Go, you need hardware that can speak fluently with your energy supplier. Smart 7kW chargers allow for seamless app integration, remote scheduling, and automatic tariff synchronization so you never miss a cheap kilowatt-hour.

Top Compatible Chargers: Ohme, Zappi, and Andersen
Not all chargers are created equal, especially when it comes to deep integration with dynamic energy tariffs. At EV Power Point, we supply and fit the industry’s most trusted manufacturers. Here are three standout models that pair brilliantly with Octopus Energy:
1. Ohme (Home Pro or ePod)
Ohme units are widely regarded as the darling of the Octopus community. Their intelligent software syncs effortlessly with tariff APIs, meaning your Ohme charger will automatically pull your Octopus schedule and adjust its charging cycles to match the cheapest slots. If your EV model is not natively supported by Intelligent Octopus Go, an Ohme charger bridges the gap perfectly.
2. Myenergi Zappi
If you are looking to combine your overnight tariff savings with renewable energy, the Zappi is unmatched. It features built-in eco-charging modes that can harness surplus solar generation during the day, while effortlessly switching to your Octopus overnight schedule when the sun goes down.
3. Andersen A2
For homeowners who refuse to compromise on aesthetics, the Andersen A2 offers minimalist, high-end design with hidden cable storage and premium wood-grain or metallic finishes. It pairs smart app functionality with a sleek profile that blends seamlessly into contemporary home exteriors.
Practical Electric Car Charger Installation Advice
Getting a home charger installed can feel daunting if you have never dealt with electrical upgrades before, but a reputable, experienced installer makes the process completely hassle-free.
When planning your installation, consider the following practical points:
- Location: Think about where you park your car overnight. Ideally, your charger should be mounted on an exterior garage wall or a driveway-facing brick pillar where the cable can easily reach your vehicle’s charging port without creating a trip hazard.
- Electrical Capacity: Most modern homes in the UK can easily support a 7kW single-phase charger. However, our in-house engineers conduct thorough safety and fuse board checks before installation to ensure your home’s electrical infrastructure is up to spec.
- Employed Engineers vs. Subcontractors: Always insist on directly employed installation engineers. Subcontractors can sometimes rush jobs, whereas an in-house team guarantees accountability, immaculate workmanship, and a mess-free handover.
