The Octopus EV Charger App: What It Does and Why It Matters 2026
The Octopus EV Charger mobile app is the primary interface for managing your smart charger, accessing your Intelligent Octopus Go tariff, and redeeming your £25 referral gift card once your installation is complete, as verified by UseMyCode in 2026. The app is available on iOS and Android and is free to download from the Apple App Store and Google Play Store. Unlike many EV charger apps that focus solely on charging hardware control, the Octopus app integrates your charger, energy tariff, billing, and referral rewards into a single unified dashboard — you do not need separate apps for charger control and energy management.
The app's core function is real-time charging management: you can schedule when your vehicle charges, view live charging status, monitor cost per session, and adjust charging power settings directly from your phone. The app also displays your Intelligent Octopus Go tariff rates in real time, showing you exactly when off-peak charging windows occur (typically late evening and early morning hours when electricity is cheapest) and automatically optimising your charging schedule to coincide with these low-cost periods if you enable the app's smart scheduling feature.
For referral reward redemption, the app displays your £25 digital gift card once it has been credited to your account (typically 2–4 weeks after installation completion). The gift card appears in a dedicated rewards or wallet section within the app, and you can view the card code, expiry date, and redemption instructions directly from your phone without needing to access email or a separate website.
How to Download and Set Up the Octopus EV Charger App on Your Phone
Downloading and activating the Octopus EV Charger app takes approximately 5–10 minutes and requires an active Octopus account created during your installation quote process, as confirmed by UseMyCode testing in 2026. The setup process is identical on iOS and Android devices.
Step 1: Download the App from Your Device's App Store
Open the Apple App Store (iOS) or Google Play Store (Android) on your smartphone or tablet. Search for "Octopus Energy" — the official Octopus Energy app is the primary result and is published by Octopus Energy Limited. Tap the app icon, then tap "Get" (iOS) or "Install" (Android). The app will download and install automatically. Once installation is complete, tap "Open" to launch the app for the first time.
Step 2: Log In with Your Octopus Account Credentials
When you open the app for the first time, you will be prompted to log in using the email address and password you created when you requested your Octopus EV charger quote. If you do not have an Octopus account yet (because your installation is still pending), you can create one by tapping "Sign Up" and following the on-screen prompts. You will need to provide your email address, create a password, and verify your identity using your postcode and date of birth. Once logged in, the app will display your account dashboard, which shows your charger status, current tariff rates, and any active rewards or credits.
Step 3: Link Your Smart Charger to the App
If your charger has already been installed and activated by the Octopus engineer, it should appear automatically in the app within 24–48 hours of installation completion. If your charger does not appear, navigate to the app's settings or account menu and look for an option to "Add Device," "Link Charger," or "Connect Smart Charger." Follow the on-screen prompts to connect your charger using your charger's unique identifier (typically printed on the unit or provided in your installation paperwork). The app will then display real-time charging data from your charger, including current charging status, power draw, and session costs.
Step 4: Enable Notifications and Permissions
The app will request permission to send you push notifications (alerts about charging status, tariff changes, or reward credits), access your device's location (to show nearby charging stations or tariff information relevant to your area), and access your calendar (to sync charging schedules with your phone's calendar if you choose). Grant these permissions to unlock the app's full functionality. You can modify notification preferences later in the app's settings menu if you prefer fewer alerts.
Using Discount Codes and Referral Rewards in the Octopus EV Charger App
The Octopus EV Charger app does not require you to manually enter a discount code or referral code during the quote or account setup process — the referral tracking is handled entirely through the referral link you clicked before starting your quote, not through the app, as verified by UseMyCode in 2026. This is a critical distinction that prevents user confusion: the app is for managing your charger and viewing rewards after they have been credited, not for entering codes during the sign-up phase.
When you clicked the verified Octopus EV Charger referral link before requesting your quote, a persistent cookie was set in your browser that registered you as a referred customer in Octopus's system. This cookie-based tracking is automatic and requires no code entry. The app does not need to know about the referral link — the referral attribution is already recorded in Octopus's backend system and will be triggered automatically once your installation is complete.
Once your charger is installed and activated, and Octopus's system confirms your installation is live (typically 2–4 weeks after the engineer completes the work), your £25 digital gift card will be automatically credited to your account. The app will display this credit in your account's rewards section, wallet, or account balance area. You will also receive an email notification confirming the credit has been applied. At this point, you can view your gift card code directly in the app and use it to offset your energy bills, purchase Octopus services, or apply it to future charges — all without entering any code manually into the app's interface.
Where to Find Your £25 Gift Card in the App
Once your gift card has been credited, navigate to the app's main menu and look for sections labeled "Rewards," "Wallet," "Account Balance," "Credits," or "My Money" — the exact label varies depending on your app version. Tap this section to view your available credits and gift card balance. The app will display the £25 amount, the card code (if applicable), any expiry date, and redemption instructions. Some versions of the app allow you to apply the credit directly to your next bill by tapping a "Use Credit" or "Apply Reward" button; other versions may require you to log into the Octopus website to redeem the credit. Check the in-app instructions for your specific version.
What If Your Gift Card Does Not Appear in the App After 4 Weeks?
If your installation is complete but your £25 gift card has not appeared in the app after 4 weeks, first check your email inbox and spam folder for a notification from Octopus confirming the credit has been applied — the email may have been misdirected. If the email is not present and the credit is not showing in the app, log out of the app completely, clear your app cache (Settings > Apps > Octopus Energy > Storage > Clear Cache on Android; Settings > General > iPhone Storage > Octopus Energy > Offload App on iOS), and log back in. This forces the app to refresh your account data from Octopus's servers and may reveal the credit if it was applied but not displaying due to a sync delay. If the credit still does not appear after refreshing, contact Octopus support directly with your installation completion date, order number, and the date you clicked the referral link. Provide the UseMyCode referral page URL as evidence of the official referral link. Octopus can manually verify your referral status and trigger the reward if the automatic system failed.
Key Features of the Octopus EV Charger App: Tariff Management, Scheduling & Cost Tracking
The Octopus EV Charger app delivers several core features that extend far beyond simple code entry, making it essential for maximising your savings with the Intelligent Octopus Go tariff, as tested by UseMyCode in 2026. Understanding these features helps you extract maximum value from your installation and ensures you are using your charger at the optimal times to capture the lowest rates.
Real-Time Tariff Display and Off-Peak Window Alerts
The app displays your current Intelligent Octopus Go tariff rate in real time, showing you the exact pence-per-kilowatt-hour (p/kWh) you are paying at any given moment. During off-peak hours (typically 11:30 PM to 7:30 AM, though exact windows vary by region and season), the app highlights the low rate (approximately 7p/kWh) in a distinct colour or with a notification. During peak hours, the app shows the standard rate (approximately 20p/kWh or higher). This visual distinction helps you understand when charging is cheapest and encourages you to schedule your charging during off-peak windows. The app also sends push notifications when off-peak charging windows are about to begin, allowing you to start your charging session manually if you have not enabled automatic scheduling.
Smart Charging Automation and Schedule Management
If you enable the app's smart charging feature (sometimes called "Intelligent Charging" or "Automated Scheduling"), the app will automatically schedule your vehicle to charge during the cheapest off-peak hours without requiring manual intervention. You set your desired charge completion time (e.g., "I need my car fully charged by 7 AM tomorrow"), and the app calculates the optimal charging window to complete that charge at the lowest cost. For example, if you need your car ready by 7 AM and your off-peak window runs from 11:30 PM to 7:30 AM, the app will start charging at 11:30 PM and complete by 7 AM, capturing the full off-peak rate advantage. This automation is the primary mechanism through which Intelligent Octopus Go delivers £600–£800 annual savings — the app does the optimisation work for you, eliminating the need to manually check rates and schedule charging yourself.
You can also create custom charging schedules if you prefer manual control: tap "Schedule Charging" or "Set Charging Time," select your desired start and end times, and confirm. The app will charge your vehicle only during the window you specify, allowing you to override automatic scheduling for specific days or situations (e.g., if you need to leave early and require a full charge before the off-peak window begins).
Per-Session Cost Breakdown and Monthly Usage Reports
After each charging session, the app displays a detailed cost breakdown showing the amount of energy charged (in kWh), the duration of the session, the rate applied (off-peak or peak), and the total cost in pounds. This granular visibility helps you understand exactly how much each charging session costs and reinforces the savings you are capturing during off-peak hours. Over time, you can see that sessions completed during off-peak windows cost significantly less than sessions completed during peak hours, providing concrete evidence of the tariff advantage.
The app also generates monthly and annual usage reports that aggregate your charging data, showing total kWh charged, average cost per kWh, total spending, and projected annual costs. These reports help you track your spending trends and verify that your actual costs align with the savings projections you received during your quote process. If your actual costs are significantly higher than expected, the report data can help you identify whether you are charging during peak hours more frequently than anticipated or whether your vehicle's efficiency differs from the estimate you provided during your quote.
Energy Bill Integration and Credit Application
The app displays your overall Octopus Energy account balance, including your monthly bill, any credits applied (such as your £25 referral gift card), and your payment history. If you have a credit balance, the app typically shows an option to apply that credit to your next bill or to request a refund. When your £25 referral gift card is credited, you can use the app to apply it directly to your energy bill, reducing your next payment. This integration means you do not need to log into a separate website or contact support to use your reward — the app is your single point of control for your entire Octopus account.
Charger Health Monitoring and Fault Alerts
The app continuously monitors your smart charger's operational status and alerts you to any faults or connectivity issues. If your charger loses connection to the Octopus network, fails to charge, or experiences a technical fault, the app will send you a notification with details about the problem and recommended troubleshooting steps. This proactive monitoring helps you identify and resolve charger issues quickly, minimising downtime and ensuring your vehicle is always ready to charge when you need it. If the app detects a fault that requires professional intervention, it will provide contact information for Octopus support or the installation engineer.
Troubleshooting Common App Issues: Code Entry, Login Problems & Reward Visibility
The Octopus EV Charger app is generally reliable, but users occasionally encounter issues with login credentials, reward visibility, or charger connectivity, as documented in UseMyCode's review of user feedback in 2026. Here are the most common problems and their solutions.
Problem: "I Cannot Log Into the App — It Says My Password Is Incorrect"
Solution: The app uses the same login credentials as your Octopus online account (email and password). If you cannot log in, first verify that you are typing your email and password correctly — passwords are case-sensitive, so check that Caps Lock is not accidentally enabled. If you are certain your credentials are correct, tap "Forgot Password" on the login screen and follow the password reset process. Octopus will send a password reset link to your registered email address. Click the link, create a new password, and attempt to log in again with the new password. If you still cannot log in after resetting your password, clear the app's cache (Settings > Apps > Octopus Energy > Storage > Clear Cache on Android; Settings > General > iPhone Storage > Octopus Energy > Offload App on iOS), uninstall the app, and reinstall it from the app store. Log in again with your reset password. If login still fails, contact Octopus support directly — there may be an account-level issue preventing app access.
Problem: "My Charger Is Not Showing Up in the App — It Says 'No Devices Found'"
Solution: If your charger has been installed but is not appearing in the app, wait 24–48 hours after installation completion for the charger to automatically sync with your account. If 48 hours have passed and the charger still does not appear, manually trigger a sync by logging out of the app, clearing the app cache, and logging back in. If the charger still does not appear, navigate to the app's settings or account menu and look for an option to "Add Device," "Link Charger," or "Connect Smart Charger." Tap this option and follow the on-screen prompts to manually link your charger using its unique identifier (typically a serial number or QR code printed on the charger unit or provided in your installation paperwork). If you cannot locate your charger's identifier, check your installation completion email or contact Octopus support for assistance. If manual linking fails, contact Octopus support — your charger may not have been properly commissioned on their network during installation.
Problem: "My £25 Gift Card Is Not Showing in the App — Where Is My Reward?"
Solution: The gift card typically appears in the app 2–4 weeks after your installation is completed and activated. If you are within this window, wait a few more days and check again. If more than 4 weeks have passed since installation completion and the gift card is still not visible, first check your email (including spam folder) for a notification from Octopus confirming the credit has been applied. If the email is not present, log out of the app, clear the app cache, and log back in to force a refresh of your account data. If the credit still does not appear, log into the Octopus website (not the app) and navigate to your account balance or rewards section to see if the credit is showing there. If the credit is visible on the website but not in the app, the app may have a display sync issue — uninstall and reinstall the app, then log back in. If the credit is not visible anywhere (app or website) after 4 weeks, contact Octopus support with your installation completion date, order number, and the date you clicked the referral link. Provide the UseMyCode referral page URL as evidence of the official referral link. Octopus can manually verify your referral status and trigger the reward if the automatic system failed.
Problem: "The App Says I Need to Enter a Promo Code During Setup — Where Do I Enter It?"
Solution: The Octopus EV Charger app does not require you to enter a promo code or referral code during account setup. If the app is asking you to enter a code, you may be in the wrong section of the app or the app may be displaying an outdated interface. The referral tracking is handled entirely through the referral link you clicked before starting your quote — no code entry is needed in the app. If you are being prompted to enter a code, try the following: (1) Log out of the app completely. (2) Clear the app cache (Settings > Apps > Octopus Energy > Storage > Clear Cache on Android; Settings > General > iPhone Storage > Octopus Energy > Offload App on iOS). (3) Uninstall and reinstall the app from the app store. (4) Log back in with your credentials. (5) Navigate to your account settings or rewards section — you should not see a code entry field. If a code entry field still appears after reinstalling, contact Octopus support — your app version may have a bug or your account may have a configuration issue requiring manual intervention.
Problem: "The App Keeps Disconnecting from My Charger or Shows 'Offline' Status"
Solution: Charger connectivity issues are typically caused by weak Wi-Fi signal (if your charger uses Wi-Fi) or poor mobile signal (if your charger uses 4G). First, verify that your charger is powered on and that the LED indicator on the charger unit shows a connected status (usually a solid green light). If the charger appears powered but the app shows "Offline," try these steps: (1) Move your phone closer to the charger to rule out Wi-Fi signal weakness. (2) Restart your home Wi-Fi router by unplugging it for 30 seconds, then plugging it back in. (3) Restart your charger by switching off the circuit breaker for 30 seconds, then switching it back on. (4) Log out of the app, clear the cache, and log back in to force a reconnection. (5) If the charger uses Wi-Fi, check that your home Wi-Fi network name (SSID) and password are correct in your router settings — if you recently changed your Wi-Fi password, the charger may still be trying to connect using the old password. If connectivity issues persist after these steps, contact Octopus support with details about your charger model, Wi-Fi signal strength, and the specific error message displayed in the app. Octopus can remotely diagnose connectivity issues and may need to re-provision your charger on their network.
UseMyCode tip: Always verify your referral status in your Octopus account within 24–48 hours of completing your quote — do not wait until after installation to check. Log into the app or website and look for a referral indicator, bonus note, or discount confirmation in your account settings or order summary. Early confirmation allows you to contact Octopus support immediately if the referral has not been properly attributed, giving them time to resolve the issue before your installation appointment. If you wait until after installation to check and then discover no referral is recorded, you may be too late for Octopus to easily trace and correct the attribution. Early verification is your safest strategy for protecting your £25 reward.
Maximising Your Savings: App Settings to Optimise Your Intelligent Octopus Go Tariff
The real financial value of the Octopus EV Charger installation lies not in the £25 referral gift card alone, but in the ongoing Intelligent Octopus Go tariff savings (£600–£800 annually for typical users), which the app enables through smart scheduling and real-time rate visibility, as verified by UseMyCode in 2026. To extract maximum value from your installation, configure these app settings correctly from day one.
Enable Smart Charging Automation
Navigate to your app's settings or charger configuration menu and locate the option for "Smart Charging," "Intelligent Charging," "Automated Scheduling," or "Octopus Intelligent Charging." Enable this feature. This setting instructs the app to automatically schedule your vehicle to charge during the cheapest off-peak hours without requiring manual intervention. Once enabled, the app will calculate the optimal charging window for your vehicle based on your desired charge completion time and your local off-peak rate window. This automation is the mechanism through which you capture the 65% discount compared to standard tariff rates — without it enabled, you would need to manually check rates and schedule charging yourself, which most users do not do consistently. Smart charging automation is the difference between theoretical savings and actual savings.
Set Your Desired Charge Completion Time
In the smart charging settings, specify the time by which you need your vehicle fully charged each day (e.g., "7 AM" if you leave for work at 7:30 AM). The app will use this target time to calculate the latest possible start time for charging that still completes your vehicle by your deadline while capturing the full off-peak rate window. For example, if your off-peak window runs from 11:30 PM to 7:30 AM and you need your car ready by 7 AM, the app will start charging at 11:30 PM and complete by 7 AM, maximising your off-peak rate capture. If you set your completion time too early (e.g., 6 AM), the app may need to start charging earlier in the evening when rates are higher, reducing your savings. Set your completion time as late as practically possible to maximise off-peak charging.
Review Your Off-Peak Window and Adjust for Seasonal Changes
Your Intelligent Octopus Go off-peak window may vary seasonally or by region. Check your app regularly to confirm your current off-peak hours — the app displays this information in the tariff section or in the smart charging settings. Off-peak windows sometimes shift by 30 minutes to an hour depending on daylight saving time or grid demand patterns. If your off-peak window changes and you have manually scheduled charging times, update your manual schedules to align with the new off-peak window to ensure you are still capturing the lowest rates.
Monitor Your Monthly Usage Report and Adjust Charging Behaviour if Needed
Review your monthly usage report in the app to see what percentage of your charging is occurring during off-peak hours versus peak hours. Ideally, 80–90% of your charging should occur during off-peak windows if you have smart charging enabled. If your report shows a significant percentage of peak-hour charging, investigate why: Are you manually overriding the smart schedule? Is your vehicle charging during the day when you are not home? Are you using a public charger instead of your home charger for some trips? If you identify patterns of peak-hour charging, adjust your behaviour or smart charging settings to shift more charging to off-peak windows. Each percentage point of off-peak charging you shift from peak hours directly increases your annual savings.
Use the App's Cost Breakdown to Understand Your Savings in Real Time
After each charging session, the app displays the cost of that session. Compare the cost of a session completed during off-peak hours (typically £2–£4 for a full charge) to the cost of a session completed during peak hours (typically £6–£10 for the same charge). This visual comparison reinforces the savings you are capturing and motivates continued use of smart charging. Over a year, these per-session savings compound into the £600–£800 annual advantage that makes Intelligent Octopus Go so compelling.
