If you are researching electric car charger installation and considering an Octopus Energy EV tariff, you may have come across a slightly confusing question: do you need a smart meter to use a smart EV charger?
The short answer is no.
You can install and use a smart home EV charger without having a smart meter in your property. However, if you want to use tariffs such as Octopus Go or Intelligent Octopus Go, you will generally need a suitable communicating smart meter as well.
Two different bits of technology are being mixed together here: the smart functionality in your EV charger and the smart meter supplied by your energy company. They work well together, but they are not the same thing. Think of them as two members of the same band who can perform separately, but sound much better when they know the set list.
Do you need a smart meter for a smart EV charger?
No. A smart EV charger does not require a domestic smart meter simply to operate.
A modern charger such as an Ohme, Myenergi Zappi or Andersen can usually connect to your home Wi-Fi or a mobile network. Its own software allows you to schedule charging, monitor energy use and control when electricity flows to the car.
The charger itself contains the relevant smart technology. It can communicate over a network, respond to charging schedules and provide information about charging sessions. Depending on the model, it may also support solar charging, load balancing and integration with energy tariffs.
The Electric Vehicles (Smart Charge Points) Regulations 2021 require new private EV charge points sold for use in Great Britain to have smart functionality. The rules apply to domestic and workplace charge points, subject to certain exclusions, and have applied since 30 June 2022.
Importantly, those regulations focus on the charge point. They do not say that you must have a smart electricity meter installed at home.
The regulations require the charger to include features such as:
- The ability to send and receive information.
- The ability to adjust the timing or rate of electricity flow.
- A measuring system to monitor electricity use and charging duration.
- Default off-peak charging settings.
- Safety, cyber-security and supplier-interoperability provisions.
- Continued charging functionality if communications are temporarily lost.
You can read the GOV.UK guidance on smart charge point regulations for the full technical detail.
So, if you simply want a 7kW smart charger installed at home, you do not need to wait until you have a smart meter. You can use the charger’s own app to schedule overnight charging, even while remaining on a standard electricity tariff.
Why do Octopus Go and Intelligent Octopus need a smart meter?
This is where the answer changes.
Octopus Go and Intelligent Octopus Go are time-of-use tariffs. The price you pay depends on when electricity is used. To apply the correct rate to your household consumption, Octopus needs accurate, regular readings from your electricity meter.
In practice, that normally means a communicating SMETS2 smart meter, or a compatible SMETS1 meter that can operate correctly on the national smart meter network and provide half-hourly readings.
Without this information, Octopus cannot reliably tell which electricity was used during the cheap period and which was used during the daytime rate. That is why a smart meter is generally required for these tariffs.
Indicative August 2026 rates
As a guide, the advertised rates in August 2026 are approximately:
| Tariff | Approximate off-peak rate | Standard off-peak window | Smart charger required? | Smart meter required? |
|---|---|---|---|---|
| Octopus Go | Around 8.5p/kWh | 00:30–05:30, five hours | No, although it is useful | Yes |
| Intelligent Octopus Go | Around 8p/kWh | 23:30–05:30, six hours, with smart charging options | Yes, or a compatible EV integration | Yes |
Regional variation applies, and rates can change. Your actual day rate, standing charge and eligibility will depend on your postcode and tariff quote, so treat these figures as a useful August 2026 guide rather than a promise carved into a very energy-efficient stone tablet.
Octopus Go is the simpler option. You receive a fixed overnight window and can schedule your car to charge during those hours using your charger or vehicle settings.
Intelligent Octopus Go is more automated. If your EV or charger is compatible, Octopus can schedule charging around your departure time and its view of the cheapest available periods. You can also receive six hours of cheap home electricity between 23:30 and 05:30, with smart charging potentially taking place at other times.
What happens if you do not have a smart meter?
You have two practical choices.
1. Ask Octopus to install or replace it
Octopus can arrange a smart meter installation, subject to availability in your area and the condition of your existing meter. If you already have an older SMETS1 meter, it may be upgraded or enrolled on the wider smart meter network rather than physically replaced. Octopus will confirm what is possible.
You do not need to have the smart meter installed before arranging your charger. However, it is sensible to ask about the meter at the same time, particularly if you want to move to an EV tariff soon after your home EV charger installation.
2. Coordinate the appointments
In some cases, the meter installation can be coordinated with the charger installation. An appropriately accredited meter engineer may fit the smart meter on the same day, while the EV installer completes the electrical work and commissions the charger.
The exact arrangement depends on who is carrying out each part of the work. Your EV charger installer will not automatically be authorised to replace your supplier-owned electricity meter, so confirm this before booking. If a combined appointment is not available, Octopus can usually arrange a separate meter visit.
On the day, the process normally involves a brief power interruption while the meter is exchanged. The meter engineer will check communications, while your EV installer will assess the consumer unit, install the dedicated circuit, route the cable and configure the charger.
For more on what is involved, see our guide to choosing the right home EV charger.
How should you pair Ohme, Zappi or Andersen with Octopus?
The main rule is simple: avoid asking multiple systems to control the same charging session at the same time.
If you are using Octopus Go, you can usually set the charger to operate between 00:30 and 05:30. With an Ohme, Zappi or Andersen, this is normally done through the manufacturer’s app or the charger’s built-in controls. Set your desired charging window, plug in and let the charger do the overnight work.
If you are using Intelligent Octopus Go, check whether your specific EV or charger is currently supported. Compatibility can change as manufacturers update software and Octopus updates its integrations. Octopus currently offers compatibility checking through its tariff sign-up process, and its Intelligent Octopus Go page now includes support for Andersen home chargers.
A few practical tips:
- Ohme: Often well suited to tariff-led charging because you can set a departure time and required charge level in the Ohme app. If Octopus is controlling the charger, avoid creating a second schedule in the Ohme app unless you know how the two systems interact.
- Zappi: A strong choice if you have solar panels or may install them later. Its ECO and ECO+ modes can prioritise self-generated energy, while its scheduled charging features can be used with a tariff such as Octopus Go. Intelligent Octopus compatibility should be checked for your exact model and setup.
- Andersen: A design-led charger that can be used with Octopus tariffs where the relevant vehicle or charger integration is supported. Its compatibility should be confirmed before switching to Intelligent Octopus Go.
If you need your car charged immediately, use the charger or Octopus app’s boost function. Just remember that an immediate “bump” charge may be billed at the standard rate rather than the discounted rate.
What are the upcoming 2028 charger meter requirements?
The government is developing the Energy Smart Appliances Regulations as part of its Smart Secure Electricity Systems programme. The intention is to bring EV smart charge points into a broader framework covering smart appliances, energy flexibility and consumer protection.
One important planned change is a requirement for relevant smart EV charge points placed on the GB market to include a Class B active electrical energy meter that complies with the Measuring Instruments Regulations 2016.
The planned timing is from 31 December 2027, effectively taking effect around 1 January 2028, subject to the final legislation and implementation arrangements.
Class B metering is intended to provide a higher and more consistent level of accuracy, with the government consultation referring to accuracy of approximately ±2% in typical conditions. Manufacturers will also need to meet conformity assessment, technical documentation and marking requirements.
For homeowners, the key point is that this is primarily a requirement for manufacturers and importers placing new products on the market. It is not currently a general instruction to replace every smart charger installed before 2028.
If you are arranging an electric car charger installation in 2026 or 2027, we recommend choosing a reputable, supported model from an established manufacturer. Your installer should also be able to explain how the charger measures energy, how its software is updated and whether it is likely to remain compatible with the tariffs and services you want to use.
So, do you need a smart meter?
Here is the simple version:
- To install a smart EV charger: No smart meter is required.
- To use the charger’s app and scheduling features: No smart meter is required.
- To use Octopus Go: A compatible communicating smart meter is generally required.
- To use Intelligent Octopus Go: You normally need a suitable smart meter plus a compatible EV or smart charger.
- To get a smart meter: Octopus can usually arrange one, either before or separately from your charger installation.
- For 2028 and beyond: New in-scope smart chargers are expected to face additional Class B metering requirements.
A smart meter is therefore not a prerequisite for getting your charger installed. It is a prerequisite for accessing certain smart energy tariffs.
Frequently asked questions
Can I install an Ohme, Zappi or Andersen charger without a smart meter?
Yes. The charger can use its own internet connection and app to schedule charging and monitor energy use. You only need a suitable smart meter if you want to access a tariff that requires one, such as Octopus Go or Intelligent Octopus Go.
Is a smart charger mandatory in the UK?
For new private charge points sold for domestic or workplace use in Great Britain, smart functionality has been required under the Electric Vehicles (Smart Charge Points) Regulations 2021 since 30 June 2022. The obligation is on the charge point and supply chain; it is not a requirement for the homeowner to have a smart electricity meter.
Can I use Octopus Go with a normal, non-smart EV charger?
Usually, yes, provided you have the required communicating smart meter. Octopus Go has a fixed cheap period, so you can use the charger’s timer, the car’s schedule or a separate control device to charge overnight. A smart charger simply makes the process easier and gives you better visibility.
Is Intelligent Octopus Go compatible with every smart charger?
No. Intelligent Octopus Go depends on communication between Octopus and a compatible EV or charger. Check the current Octopus eligibility checker for your exact car and charger model before switching. Compatibility lists can change.
Should I wait until 2028 to install my charger?
Not necessarily. A quality smart charger installed now can provide years of useful service, and the 2028 requirements are focused on new in-scope products placed on the market. If you are ready for home charging, it is usually more practical to choose a suitable compliant charger now than to postpone the convenience and potential savings.
