Is registration verification mandatory?

Yes. Companies registering in the REV must hold an annual registration verification statement. The verifier processes the results in the REV before 1 May, covering the registrations of the previous calendar year.

Who pays for the registration verification?

The registrant. You contract a recognised registration verifier yourself and pay for the verification. The NEa does not assign a verifier.

What if the verification is not completed successfully?

As the registrant you then provide a report of findings. Depending on the findings, the NEa may subsequently correct registrations or suspend the crediting of EREs.

When should I approach a verifier?

In good time — the NEa explicitly advises this. Waiting until spring means competing for capacity with every other registrant facing the same 1 May deadline.

Registration verification: how to prepare for the annual requirement

The annual registration verification is the moment an independent verifier establishes whether your registered renewable energy complies with the legal requirements. It is not a voluntary check: without a verification statement you do not meet the conditions of the scheme, and the NEa can take enforcement action.

Three characteristics make this obligation heavier in practice than it appears on paper.

1. You arrange (and pay for) it yourself

Verification is not a government service. You contract a recognised registration verifier yourself and bear the costs. Fees scale with the scale and complexity of your registrations: number of deliveries, number of connections (EANs), diversity of evidence and the quality of your administration.

The practical consequence: a messy evidence file is not only a risk, it is directly more expensive. Every hour the verifier spends searching appears on the invoice.

2. The deadline falls early in the year

The verifier processes the results of the verification covering the previous calendar year no later than before 1 May in the REV. This means field and file reviews must take place in the first quarter — immediately after the registration deadline of the last working day before 1 March.

Anyone who tries to schedule verification only in March discovers that verifiers are fully booked. That is why the NEa explicitly advises getting in touch in good time.

3. A negative outcome has follow-through

If the verification is not completed successfully, you provide a report of findings. Findings can lead to correction of registrations — and remember that the NEa can additionally correct ex officio up to five years after the registration year, independently of the verification. A verification problem in 2027 can therefore still have financial consequences years later.

How to prepare: the practical checklist

Ultimately the verifier tests three things: are the deliveries real, are they yours, and is the calculation correct. Align your preparation accordingly:

Completeness of delivery data. Every registered delivery must be traceable to session or meter data from an approved measuring instrument, with date, volume and EAN. Before the verification, test whether you can produce random samples within minutes.
Continuity of the file. The verifier does not look at loose documents but at the chain: from charging session to registration. Gaps in the chain become findings.
Evidence of the renewable share. For grid electricity the grid-average share suffices within the scheme; anyone calculating with 100% renewable (direct line, generation at the same address) must substantiate that with guarantees of origin or contracts.
Accessibility and a point of contact. Ensure the verifier has one point of contact with access to the complete file. Fragmentation across departments or suppliers is the most common cause of delay.
Learn from previous years. Findings from earlier verifications that have not been structurally resolved are guaranteed to return — and then weigh more heavily.

Outsourcing changes the equation

With a registration service provider, verification is no longer an annual project but a processed part of the routine: the file is built audit-proof throughout the year, precisely to the requirements the verifier will set. That turns verification from a moment of stress into a formality.
