Under the hood

Six places where your bill can lie

We don't guess: we cross-check your data with public scales (regulated tariff, TURPE, excise) and your real meter readings.

The subscribed power

Are you paying every month for kVA you never use?

The tariff option

Base or Off-peak: the right one for your real usage, not for habit?

TURPE & delivery

The grid share — a third of the bill — billed at the right rate?

Excise (ex-CSPE)

The tax that replaced the CSPE — at the right rate, no hidden surprise?

Estimated vs actual reading

Estimated indexes inflating the bill between two real readings?

Adjustments & catch-ups

A catch-up over more than 14 months is often contestable. We check.

Your questions

Before you start

Is it really free?+
The diagnosis is 100 % free and with no commitment. If you then decide to recover an overcharge, we're paid on success only — a percentage of what you recover, never anything otherwise.
What do you do with my bill?+
It's analyzed to produce your diagnosis, then encrypted and siloed. We never resell it and you can request its deletion at any time. Nothing is kept until you give your explicit consent.
How much can I recover?+
It depends on the anomalies found. The law lets you go back up to 5 years (statute of limitations, art. 2224 of the Civil Code). The report gives you an estimate item by item; the final amount is confirmed with supporting documents.
Do I have to switch supplier?+
No. Our analysis is independent and imposes no change. We tell you what's fair — you're free to act. We don't sell energy and take no supplier commission.
Is my data secure?+
Yes. Every use of your data is subject to a separate consent, timestamped and revocable in one click from your area. That's the principle of our consent vault.

Your bill probably has something to tell you.
