Which charging data does an ERE provider share, and with whom?

To receive an ERE payment, you share more than just a kWh figure: an ERE provider processes your charging data as well as your identity and payment details, and files them with the official register on your behalf. This article follows that data flow step by step, states what is known and what isn’t, and explains what rights you have.

The data flow: from charge point to register

1. Charge point. An integrated, MID-certified meter records each charging session in kWh, with a timestamp and the connection it was charged on.
2. Back office or charge card platform. The session data first lands in the system of the charge point or charge card provider - sometimes the same company as your ERE provider, sometimes a separate party.
3. ERE provider (registration service). The provider retrieves or receives this session data, links it to your identity and payment details, and files the whole package with the NEa. Not every provider does this entirely in-house: GridCredits and Laadnet, for example, explicitly state that the technical processing runs via their partner Joulo.
4. Official register. The NEa registers the submitted EREs. Until now this has run on a self-reported list of providers; from October 2026 it is replaced by a register of actual REV account holders.
5. Fuel suppliers. They buy the registered EREs to meet their statutory reduction obligation. They see the traded units, not your name or individual charging behaviour.

What data is actually involved?

Category	Examples
Charging data	kWh charged per session, timestamp, connection or charge point ID, meter readings
Identity details	Name, address, and for business use a company registration number
Payment details	IBAN for paying out the reward
Contact details	Email address and phone number for account management
Platform link	With some providers: a link to a specific app or back office, for example Vattenfall, Laadnet or 50five

Why is all of this needed?

The amount of data involved relates to what the system is trying to guarantee: that every registered ERE genuinely corresponds to real, verifiable charging electricity. That’s why a MID-certified meter is required rather than a self-reported figure, and why your identity and connection are linked to the charging data - without that link there would be no way to check that you, rather than someone else, are entitled to the payment for that specific charge point. Payment details are needed so you can actually be paid.

Who sees your data, and who doesn’t?

Your ERE provider generally sees the full combination: who you are, where you charge, how much, and with which payment details. Where the technical registration runs via a partner such as Joulo, that partner processes the charging data on the provider’s behalf. The NEa, as the register’s administrator, sees which volumes have been registered and by which provider, but doesn’t itself monitor your charging behaviour. Fuel suppliers, the ultimate buyers of EREs, only see the traded units - not your personal data or individual sessions. EREVergelijken.eu itself is not a party in this chain: we compare providers and refer you onward, but we don’t register any EREs ourselves and so don’t see your charging data at the provider you choose.

If you only use our own tools, such as the charger check or the calculator, what we collect stays limited to what you enter there yourself, plus your email address if you sign up for the newsletter. Only once you actually register with a provider - through us or directly - does the fuller combination of charging, identity and payment data come into play, and from that point their terms and privacy policy apply, not EREVergelijken.eu’s.

What isn’t public yet?

Not every provider discloses the same level of detail about its processing. Unknown, or not disclosed by default, includes: the exact retention period for charging and personal data per provider, whether sub-processors are used besides the partners named above, and the precise level of detail in the shared data - individual sessions versus aggregated totals only. Where this isn’t stated in a provider’s privacy policy, we treat it as unknown rather than filling it in ourselves.

The register changes from October 2026

Until now, the list of ERE providers has largely been self-reported: providers state themselves that they’re registered with the NEa. From October 2026 the NEa replaces this with a register of actual REV account holders. That changes nothing about what data you share, but it does make it easier to verify which providers actually hold an active NEa account. A listing - old or new - is, either way, not a quality mark for privacy or service; it’s only a requirement to be allowed to register EREs.

Your rights and what you can do yourself

The usual privacy rights apply to how an ERE provider processes your data: you can generally request access to your data, have it corrected or deleted, and withdraw consent you’ve given. Exactly how you do that varies by provider. So always read the privacy policy of the provider you’re signing up with, before you link your charge point: it states who processes the data, how long it’s kept, and whether sub-processors such as a technical partner are involved. We don’t give legal advice here about your specific situation; if in doubt, the provider itself, or a legal adviser, is the right point of contact.
