Fast answer: Octopus Intelligent Go vs OVO Charge Anytime
Octopus Intelligent Go vs OVO Charge Anytime: the better option is the one that gives you the most kWh at a cheaper overnight (or smart‑charge) rate with compatible kit and reliable scheduling at your address. Intelligent Go is a dedicated smart EV tariff; Charge Anytime is a smart‑charging add‑on style approach. Eligibility and prices vary—check live quotes.
Most important check
Whether your EV / charger / smart‑charging setup is compatible and can reliably pause/resume charging.
Most important number
Your monthly home charging kWh (roughly miles driven ÷ EV efficiency). That determines whether a specialist EV plan is worth it.
Quick rule of thumb
If you can shift charging into the cheap window and you do regular home charging, you’re more likely to benefit.
Important: We don’t publish specific supplier unit rates on this page because they change frequently and depend on your postcode, payment method and meter. Use live quotes for exact figures.
How these two options usually work (in plain English)
Both are designed to automatically schedule EV charging for cheaper, lower‑demand periods—without you staying up to plug in at a specific time.
Octopus Intelligent Go (what to expect)
- You set a target “ready by” time and desired charge level.
- The system can start/stop charging to match cheaper periods.
- You typically get a cheap rate window for EV charging, but exact details depend on the tariff terms and your setup.
- It may rely on an approved EV/charger integration and ongoing connectivity.
OVO Charge Anytime (what to expect)
- Often works like an EV smart‑charging add‑on which credits/rebates eligible smart‑charged kWh.
- Charging is managed via app/integration so it can shift load automatically.
- How savings show up can differ (for example, via a credit for smart‑charged energy).
- Compatibility and data accuracy matter (meter readings / integration logs).
What can make smart charging fail (and how to reduce the risk)
- Connectivity issues (Wi‑Fi / mobile signal)
- If the charger or car can’t “phone home”, scheduling may default to normal charging. Place your charger hub where signal is stable or consider an extender if appropriate.
- Vehicle or charger not supported (or support changes)
- Approved device lists can change. Always verify compatibility in the supplier’s app/website before switching.
- You override the schedule
- “Boost charge now” features can push more energy into peak times. Useful occasionally, but it can reduce the benefit.
- Time‑of‑use patterns don’t match your lifestyle
- If you use lots of electricity during the day/evening, a cheap overnight EV rate might not compensate for higher peak rates (where applicable). You need to look at the whole bill, not just EV charging.
Check what’s actually available for your postcode
Because EV tariffs and smart‑charging offers can vary by region, meter type, payment method and account history, the quickest way to decide is to compare live options side‑by‑side.
Tip: Before switching, find out whether you have a smart meter communicating properly (particularly if you’re on half‑hourly readings). If you’re unsure, your supplier can confirm your meter status and readings setup.
Two realistic scenarios (with numbers) to help you decide
These examples show the decision logic, not live pricing. We use typical EV efficiency assumptions and compare what happens when you can (or can’t) keep most charging in the smart/cheap periods.
Scenario A: Regular commuter, mostly home charging
- Driving: 900 miles/month
- Efficiency assumption: 3.5 miles/kWh (typical for many EVs in mixed use)
- Home charging: 85% of miles
- Estimated home charging energy: 900 × 0.85 ÷ 3.5 ≈ 219 kWh/month
If you can smart‑charge most of that 219 kWh in the cheap window, a specialised EV approach is more likely to matter. Your decision then hinges on: (1) compatibility reliability, and (2) how the rest of your household electricity is priced outside the cheap periods.
Scenario B: Low mileage, lots of public charging
- Driving: 350 miles/month
- Efficiency assumption: 3.2 miles/kWh (more motorway/winter)
- Home charging: 50% of miles
- Estimated home charging energy: 350 × 0.50 ÷ 3.2 ≈ 55 kWh/month
With ~55 kWh/month at home, even a very good EV rate may not move your total annual bill much. In this case, you may prioritise overall household value (unit rates + standing charges + customer service) and treat EV smart charging as a “nice to have”.
How to estimate your own kWh: monthly miles ÷ (miles per kWh). If you don’t know efficiency, a conservative planning range is often 2.8–4.0 miles/kWh depending on model, temperature and driving style.
Octopus Intelligent Go vs OVO Charge Anytime: side‑by‑side comparison
This table compares how the products are structured and the practical checks you’ll want to do. For exact prices and eligibility at your address, use live quotes.
| What you’re comparing | Octopus Intelligent Go (typical setup) | OVO Charge Anytime (typical setup) |
|---|---|---|
| Type | Smart EV tariff with scheduled charging | Smart‑charging offer typically applied via app/integration (often via credit/rebate mechanism) |
| What you control | “Ready by” time, target charge, and charging preferences within their system | Smart‑charge scheduling in the app, plus any “boost” options |
| Compatibility risk | Depends on supported EVs/chargers and reliable connection | Depends on supported EVs/chargers and accurate tracking of smart‑charged kWh |
| Best for | Drivers who can regularly charge at home and want a defined cheap charging schedule | Drivers who prefer a smart‑charging‑tracked approach (often with credits) and want flexibility around standard tariffs |
| Watch‑outs | If most of your household usage is outside cheap periods, the overall bill may not improve | If smart‑charged sessions aren’t recognised, you may miss the intended benefit |
| What to check before switching | Meter requirements, tariff terms, device compatibility list, and how “boost” charging is billed | How credits are calculated/paid, eligible charging definition, and what happens during outages or manual overrides |
Decision checklist (quick and practical)
- How many kWh/month do you charge at home? (If it’s small, prioritise overall household value.)
- Can you reliably plug in most nights? Smart charging works best when you give it time to schedule.
- Is your EV/charger on the supported list? Check directly with the provider before switching.
- Do you often need “charge now”? Frequent boosts can reduce the benefit.
- Are you likely to change car/charger soon? Future compatibility matters.
Who each option tends to suit (and who it doesn’t)
Often suits:
- Off‑street parking + home charger
- Predictable overnight charging
- Comfortable using apps/automation
Often not ideal:
- Unreliable signal at parking spot
- Very low home charging volumes
- Regular urgent top‑ups at peak times
Costs, exclusions and common pitfalls (UK‑specific)
Smart EV tariffs can be excellent—but the savings aren’t automatic. These are the issues we see most often when people switch without checking the fine print.
1) Exit fees and switching timing
Some fixed tariffs have exit fees. If you’re on a fix, check your end date and any fees before moving. If you’re on a variable tariff, fees are less common—but always confirm.
2) Smart meter setup and half‑hourly reads
Some smart‑charging approaches work best with accurate half‑hourly consumption data. If your smart meter isn’t communicating, billing and tracking can be messy.
3) Standing charges still apply
Even with a great EV rate, you’ll still typically pay standing charges for gas/electricity. Compare the whole tariff: standing charge + peak/off‑peak rates (where relevant).
4) Boost charging can be expensive
If you frequently override schedules to charge immediately, you may end up paying higher peak rates for a large share of your EV usage.
5) Charger installation and landlord permission
Tenants usually need landlord permission to install a charger. If you can’t install, consider whether your vehicle supports smart charging through a compatible plug-in setup (where offered) or rely on public charging.
6) Offer terms can change
Apps, integrations, and eligibility criteria can change over time. If you’re switching mainly for EV charging, consider how you’d cope if the smart feature became less reliable.

FAQs
Is Octopus Intelligent Go cheaper than OVO Charge Anytime?
It depends on the live prices available at your postcode and how much of your EV charging is recognised as smart/cheap‑window charging. The meaningful comparison is your whole bill: EV charging kWh at the discounted rate plus household usage at the standard/peak rate (and standing charges).
Do I need a smart meter for Intelligent Go or Charge Anytime?
Often, yes—at least for the smoothest experience—because smart charging and time‑of‑use billing typically rely on accurate readings. Requirements vary by provider and tariff. If your smart meter isn’t communicating, you may see delays or manual steps when bills or credits are calculated.
What if my car or charger isn’t compatible?
If your model isn’t supported, the smart scheduling may not work correctly (or at all), which can wipe out the benefit. Before switching, check the provider’s current compatibility list and consider whether you’re likely to change vehicle/charger during the tariff term.
Can I get these deals if I’m a tenant?
You can usually switch energy supplier as a tenant if you pay the bill, but installing an EV charger typically needs landlord permission. If you can’t install a charger, consider whether your EV supports smart charging via a compatible method offered by the provider, or whether a standard tariff is better.
Will smart charging always happen in the cheap window?
Not always. Smart charging can be affected by connection issues, manual overrides (boost charging), or the system needing to meet your “ready by” time. In some cases, charging may occur outside discounted periods. That’s why it’s important to monitor your first few weeks and adjust settings.
Is it worth switching supplier just for EV charging?
It can be—if you charge a meaningful amount at home and can shift most of it into smart/overnight periods. If your home‑charging kWh is low, your overall unit rate, standing charges, and customer service may matter more than the EV feature.
Could I end up paying more on an EV tariff?
Yes. If the non‑cheap periods are priced higher (where applicable) and your household uses lots of electricity at those times, you can lose more than you gain on EV charging. Always compare the full tariff structure and sanity‑check it against your routine (cooking, washing, heat pumps, home working).
What should I do before I switch to avoid billing surprises?
Take meter readings (even with a smart meter), check if you’re in a fixed deal with exit fees, confirm direct debit details, and keep screenshots of your smart‑charging settings. After switching, review your first bill/statement and confirm your EV sessions are being counted as expected.
