About us
Enerva audits your electricity bill and tells you exactly where you overpay — even when the honest answer is "don't switch supplier, just lower your contracted power."
Why we exist
Most Spanish households overpay for electricity and have no easy way to know it. Comparison sites live off the switching commission, so they almost never tell you to stay put. We do: the audit is free, and when the cheapest move is not switching, we say so.
How it works
You scan the QR code the law mandates on every electricity bill — or connect your real hourly Datadis meter data — and we compute your audit from deterministic data, not estimates. Every recommendation carries a one-click deep link to the official CNMC comparator so you can check us.
Our rules, written into the code
- We never sell or share your data for marketing.
- Zero sales calls, ever. It's a condition you accept before any assisted switch.
- If we ever earn a retailer commission, you see it in €/kWh next to the recommendation. A commissioned recommendation without a third-party comparison is not shown — it's blocked in code.
- If the cheapest move is not switching supplier, we tell you that.
