Questions, answered
The things people ask before uploading.
Your full name, address, IBAN and NIF are stripped from the bill before analysis — they're never written to our database and never sent to any AI model. Once you unlock a report, we save your name, email and usage from your bill. That's it.
No. You can upload a bill and see a partial analysis without entering your email. We only ask for your email if you want a full copy of the report and the report sent to you.
Our tariff database is refreshed automatically every day from each provider's public site.
No. Switching energy provider in Spain is free, there's no service interruption, and the new provider handles most of the paperwork. Switching typically completes in 5–7 days.
Then we tell you. If none of our partner providers come out lower than your current tariff for your usage, the analysis will say so and you keep what you have.
Unlike traditional comparison websites, we don't list every provider on the market. We carefully curate the energy companies we work with, focusing on suppliers that offer competitive prices, transparent contracts, and genuinely good customer service.
We only partner with providers that supply 100% renewable electricity and have a proven track record of positive customer reviews on Trustpilot. Our goal isn't to overwhelm you with hundreds of options — it's to recommend providers we'd confidently choose ourselves.
Where possible, we also negotiate exclusive offers and discounts that are only available through HolaSwitch. This means you can often access better rates than if you switched directly with the provider.
Most importantly, you're never signing a contract with HolaSwitch. Your energy contract is always directly with the provider you choose. We simply help you compare your options, understand the small print, and help you where needed to complete the switch — completely free of charge. There are no hidden fees, and your electricity supply is never interrupted during the switch.
Finally, we're built specifically for English, Dutch and other language speakers living in Spain. We explain your Spanish energy bill, help you understand exactly what you're paying for, and make switching providers simple, transparent, and stress-free.
