Tessie Discount Code 2026: How the Offer Works and Whether It Is Worth It
Last Updated: July 1, 2026
Tessie offers a free trial so you can test the full app before paying. If you go through a referral link, you may also get a discount on your first subscription period. Tessie pricing starts at roughly £4.99/month or £39.99/year, with a lifetime option available. The app connects to your Tesla and adds better automation, detailed battery health tracking, charging stats, and widgets that the official Tesla app does not provide.
Quick take: a Tessie discount code is a nice bonus, but the real decision is whether you will use the extra features enough to make the subscription worth keeping after the discount ends.
Tessie offers a free trial and occasional referral discounts on its Tesla companion app, which costs £4.99 per month or £39.99 per year. The app adds battery health tracking, charging cost calculations, automations, widgets, and trip logging on top of what the official Tesla app provides. This guide covers how the Tessie discount code works, what you get at each price point, and whether the subscription is worth keeping after the discount ends.
Tessie Discount Code: Quick Answer
A Tessie discount code can save you money on your first month or first year, but the offer is not the reason to subscribe. Tessie is worth paying for if you want more control, better data, and faster access to your Tesla than the official app gives you. The discount just makes the first step cheaper.
Tessie runs a referral programme rather than public coupon codes. The usual path is: you sign up through a referral link, get a free trial period, and if the referral terms include a discount, it applies to your first paid subscription. Ignore third-party coupon sites. They are almost always stale, misleading, or designed to collect your email rather than to save you money.
What Tessie Does That the Tesla App Does Not
The standard Tesla app covers the basics: lock, unlock, climate, charge limit, and a handful of other controls. Tessie adds layers on top of that.
Battery health tracking. Tessie plots your battery degradation over time, compares it to other cars of the same model and age, and shows you whether your battery is aging normally. For owners who care about long-term battery health, this is the headline feature and the main reason to subscribe.
Charging stats and cost tracking. Tessie logs every charge, calculates the cost based on your electricity rate, and shows you efficiency trends. If you charge at home on an EV tariff like Intelligent Octopus Go, you can set your off-peak rate and Tessie will tally exactly what each charge costs.
Automation. Tessie can trigger actions based on conditions. You can set the car to preheat at a specific time, close the windows when rain is forecast, or start charging when your electricity rate drops. The official Tesla app does not offer this kind of conditional automation.
Widgets and shortcuts. Tessie has iOS and Android widgets that put common controls on your home screen. You can also create Siri Shortcuts or Google Assistant commands. Instead of opening an app and waiting for it to wake the car, you tap a widget or speak a command.
Trip logging and sentry viewer. Tessie logs every drive with efficiency data. It also lets you view sentry mode footage from the app, which the official Tesla app only recently started supporting and still handles less smoothly.
Tessie Pricing at a Glance
| Plan | Price | What You Get |
|---|---|---|
| Monthly | ~£4.99/month | Full feature access, cancel anytime |
| Annual | ~£39.99/year | Same features, roughly 33% cheaper than monthly |
| Lifetime | ~£199 one-time | Pay once, use forever, includes all future updates |
All plans include a free trial, typically one month. You can cancel before the trial ends and pay nothing. The lifetime plan is the best value if you plan to keep the car for more than four years and know you will use the app regularly.
How the Tessie Referral Discount Works
Tessie does not publish discount codes on coupon websites. The referral programme works like this:
- An existing Tessie user shares their referral link.
- You click the link and download the app or sign up on the Tessie website.
- You get a free trial, usually one month.
- If the referral programme is actively offering a discount, it applies when you first pay.
The referral benefit can vary. Sometimes it is a percentage off your first month or year. Sometimes it extends the free trial. Check what is shown on the signup screen before you enter payment details. That screen is the only reliable source for what the current offer includes.
Third-party coupon sites will show you a list of expired or generic codes. Skip them. They add friction with no benefit.
Who Tessie Suits
Tessie makes the most sense for Tesla owners who:
– Want to track battery health and degradation over years of ownership
– Charge at home and want precise cost tracking per charge
– Use automations to preheat, schedule charging, or trigger climate based on conditions
– Prefer widgets and voice shortcuts over opening the app every time
– Log trips and want efficiency data across all their drives
Tessie is less useful for owners who:
– Are happy with the official Tesla app and do not want more data
– Rarely check charging stats or battery health
– Do not use widgets, shortcuts, or automations
– Only keep the car for a year or two and do not care about long-term battery trends
Common Questions
Is there a working Tessie discount code for 2026?
Tessie uses a referral programme rather than public discount codes. The best approach is to use a referral link, which may include a discount on your first subscription period. Check the signup screen before paying to confirm what the current offer includes. Avoid third-party coupon sites. The codes they list are almost always expired or never worked in the first place.
How long is the Tessie free trial?
Typically one month. You get full access to all Tessie features during the trial. Cancel before the trial ends and you pay nothing. Tessie does not require payment details upfront in all cases, but check the signup flow to confirm.
Does Tessie work with all Tesla models?
Yes. Tessie supports Model S, Model 3, Model X, Model Y, and the Cybertruck. It works with cars running on the Tesla API, which covers most Teslas on the road. Some features vary by model and software version, but the core features including battery health, charging stats, and automations work across all supported vehicles.
Can I cancel Tessie after the free trial?
Yes. Cancel through the app store (iOS) or Google Play (Android) before the trial period ends and you will not be charged. If you subscribed through the Tessie website, cancel in your account settings. There is no long-term contract and the monthly plan can be cancelled at any time.
Is Tessie worth the subscription after the discount ends?
It depends on how much you use the features. Battery health tracking alone is worth the annual fee for owners who plan to keep their Tesla long-term and want to monitor degradation. Charging cost tracking pays for itself if it helps you shift more charging into off-peak hours. If you use the automations and widgets daily, the subscription is easy to justify. If you install it and forget it after the first week, it is not.
Does Tessie drain the Tesla battery?
Tessie polls the car for data, which can wake it from sleep and use a small amount of battery if the polling interval is set too aggressively. Tessie has settings to reduce the polling frequency or disable background polling when the car is asleep. Most users report negligible battery drain with sensible settings. If you notice your car waking more often after installing Tessie, adjust the polling interval in the app settings.
I have used Tessie with my 2021 Tesla Model 3 Long Range since shortly after buying the car. The battery health tracking is the feature I check most often. Watching the degradation curve over time, compared to the fleet average for cars of the same age and mileage, gives me a clear picture of whether the battery is holding up as expected.
The charging cost tracking is the second most useful feature for me. I am on Intelligent Octopus Go at 8p/kWh overnight, and Tessie tells me exactly how much each charge cost rather than me estimating from the car's reported kWh added. When you charge at home two or three times a week, seeing the real cost per charge adds up to a clearer picture of what the car actually costs to run.
Would I pay full price without a discount? Yes, for the battery health and charging data alone. The widgets and automations are nice extras. But the subscription is only worth it if you actually open the app and use the data. If you install Tessie and never look at it after the first week, even a free trial was not really worth your time.
You can use my referral link to start the free trial and try the features I use on my own Model 3 before deciding whether to keep it.
