Let’s be honest for a second. When you first switched to an electric vehicle, you probably pictured a future of silent cruising, zero tailpipe emissions, and smugly driving past petrol stations with their depressing £1.50+ per litre boards. But then reality hit your first energy bill, and you realized that plugging your pride and joy into a standard 3-pin plug, or worse, relying on pricey public rapid chargers, was making your wallet weep just a little bit.
If you are still sitting on a standard variable electricity tariff, wondering why your monthly direct debit looks like a mortgage payment, we have good news. You are leaving serious cash on the table. When it comes to octopus energy ev charging, tariffs like Octopus Go and Intelligent Octopus Go can completely transform what it costs to run your car. But how do you actually unlock those headline-grabbing savings, and what gear do you need on your wall to make it happen?
Grab a brew. Here is everything you need to know about slashing your motoring costs, whether you are pottering around the West Midlands or road-tripping across the UK.
Design & Build Quality
When you are investing in home energy upgrades, the hardware on your wall matters. It needs to withstand British weather, from freezing Worcestershire frosts to torrential Warwickshire downpours, while looking sleek enough that your neighbours don’t think you’ve bolted an industrial generator to your front brickwork.
Smart chargers like the Myenergi Zappi, Ohme Home Pro, and Zaptec Go aren’t just clever brains in plastic boxes; they are piece-of-mind engineering. They feature robust, weatherproof casing (typically IP65 rated), impact-resistant faceplates, and tidy cable management systems. Whether you opt for a tethered unit with a pre-attached cable or a clean untethered socket, manufacturers are designing chargers that look like high-end smart home accessories rather than utility meters. When our in-house engineers at EV Power Point install your unit, we make sure the cabling is discreet, secure, and built to last.
Smart Features & App
So, how does the magic actually happen? It all comes down to smart scheduling and app control. Traditional EV charging is as dumb as a toaster: you plug the car in at 6 PM, and it starts gulping electricity immediately at peak daytime rates.
Smart tariffs and smart chargers change the game entirely. With Intelligent Octopus Go, energy supplier Octopus Energy communicates directly with your compatible EV or smart charger (such as an Ohme or Zappi). You simply tell the app when you need your car charged and ready to go by the morning (say, 7:00 AM), and the system automatically coordinates the cheapest overnight window, typically a generous six-hour block from 11:30 PM to 5:30 AM, charging your car when wholesale energy prices hit rock bottom.
Even better? That super-cheap off-peak rate (hovering around 7p to 8p per kWh) applies to your entire home during those smart charging slots. That means you can program your washing machine, dishwasher, and immersion heater to kick off in the middle of the night alongside your car.
Solar Compatibility
If you are already generating your own green electricity via rooftop solar panels, you can double down on your savings. Many modern chargers, most notably the Myenergi Zappi, feature dedicated eco-modes that allow you to divert excess solar generation straight into your EV battery instead of exporting it back to the grid for pennies.
Combining solar generation with an overnight smart tariff gives you the ultimate energy setup: free green miles during sunny days and ultra-cheap grid top-ups overnight. If you are curious about how to tie your solar array into your home charging setup, take a look at our guide on charging your ev with solar panels.
Installation
You might be wondering: can I just plug my car into any old wall socket and sign up for Octopus Go? Technically yes, but practically and safely, no. Charging an EV pulls a heavy, continuous load for hours on end. Standard domestic sockets simply aren’t designed for that kind of sustained marathon and can pose a genuine fire hazard.
This is where professional installation by manufacturer-approved engineers makes all the difference. As a local, family-run team operating across Worcestershire, Warwickshire, and the West Midlands, we don’t subcontract our work. Our directly employed engineers handle everything from electrical load assessments and earthing checks to neat cable routing and smart app setup.
We can get your new home charger installed in as little as five days after providing a fixed-price quote with zero hidden fees.

Price & Finance
Let’s talk numbers. Can you really save £500+ a year? Let’s break down a realistic scenario for a typical UK driver covering 10,000 miles a year in an EV that averages 3.5 miles per kWh (roughly 2,850 kWh consumed annually).
| Charging Method | Average Unit Rate (kWh) | Annual Fuel Cost (10,000 miles) | Annual Savings vs Standard Tariff |
|---|---|---|---|
| Standard Variable Tariff (Daytime price cap) | ~25p – 27p | ~£712 – £770 | Baseline |
| Octopus Go (Fixed 4/5h window) | ~8.5p – 9.5p | ~£242 – £270 | ~£470+ saved |
| Intelligent Octopus Go (Smart 6h window) | ~7p – 8p | ~£200 – £228 | ~£510 to £550+ saved |
| Public Rapid Chargers (On-the-go DC) | ~55p – 80p | ~£1,570 – £2,280 | (You’d pay more, not less!) |
As the table shows, shifting your charging routine from a standard daytime rate or public rapid chargers to Intelligent Octopus Go easily saves you upwards of £500 a year on fuel alone. Over a three-to-five-year ownership cycle, that pays for your entire charging setup multiple times over.
Worried about the upfront cost of hardware and installation? You don’t have to break the bank. We offer flexible ev charger finance options, including interest-free financing with easy monthly payments and buy-now-pay-later plans tailored to suit your household budget.
Which One Should You Choose?
With so many variables: your car model, your daily mileage, whether you have solar panels, and whether you prefer Ohme, Zappi, or Zaptec: choosing the right hardware and tariff can feel slightly overwhelming.
The golden rule? Don’t guess. As manufacturer-approved installers, we offer honest, jargon-free guidance with no hard sell. Whether you need a smart 7kW charger installed at your home in Worcester or a commercial setup for your business, we will match you with the exact equipment that plays nicely with Octopus smart tariffs.
