How do we calculate your savings?

Unlike generic comparison websites, we don’t rely on rough estimates.

We look at:

  • Your real consumption
  • Your contracted power
  • Your tariff structure
  • Whether you’re on regulated or free market
  • Solar surpluses at market or fixed price

Our goal isn’t to make you switch.

It’s to make sure you only switch if it genuinely benefits you.

Designed for Expats & Property Owners in Spain

Many expats and second-home owners in Spain are on electricity tariffs that do not match their real usage.

Spanish electricity bills can be complex, especially if you’re unfamiliar with:

• Time-of-use periods
• Contracted power charges
• Fixed vs indexed tariffs
• Regulated vs free market structures
• Solar surplus compensation rules

Our electricity savings calculator is designed to simplify all of this. Using the real data from your latest bill, we compare your current costs with what you would pay under our rates. The result? A clear estimate of your potential monthly and annual savings – based on your real consumption, not generic averages.

    FAQ

    How does the electricity savings calculator work?

    Our calculator uses the real data from your latest electricity bill to estimate what you would have paid under our tariffs.

    We analyse:

    • Your total kWh consumption
    • Your contracted power (potencia contratada)
    • Your tariff structure
    • Whether you are on a fixed or indexed rate
    • Solar surplus (if applicable)

    We then simulate your annual cost under both fixed and market-indexed options to estimate potential savings.

    Will my electricity be interrupted?

    No. Your physical electricity connection remains exactly the same. Only the billing company changes.

    Is there a contract commitment?

    It depends on the type of tariff. Our indexed tariffs do not have a minimum contract period. However, with fixed prices, we do have a one-year minimum contract period in order to guarantee that price throughout the entire period.

    Is the savings estimate 100% accurate?

    Our calculator provides a highly accurate estimate because it is based on your real consumption data and current regulated charges.

    It reflects:

    • Your actual kWh usage
    • Your contracted power
    • The billing period
    • Solar surpluses (if aplicable)

    However, it is still a digital tool. No automated system can analyse your situation with the same depth and judgement as a real energy advisor.

    That’s why, before any contract is finalised, our team personally reviews your full electricity bill to:

    • Confirm the projected savings
    • Check for hidden charges or special conditions
    • Verify that the recommended tariff genuinely suits your usage

    We never rely solely on automation.

    The calculator gives you a reliable estimate — our human review ensures you can switch with confidence.

    Do you compare both fixed and indexed tariffs?

    Yes. Our calculator estimates your cost under a fixed and a market-indexed rate. Then it show which option would be more suitable based on your bill provided

    What happens after I upload my bill?

    Once submitted:

    1️⃣ We analyse your data
    2️⃣ We calculate your potential savings
    3️⃣ If savings are confirmed, we contact you personally
    4️⃣ We explain the recommended tariff clearly in English

    There is no automatic contract activation.

    We only proceed if you choose to move forward.

    Will I receive sales calls?

    No aggressive sales tactics. We only contact you regarding your savings analysis. If, after you make the comparison, you are not interested anymore in it, you can let us know and we remove you from the contact list.

    Our goal is clarity – not pressure.

    Is my data secure?

    Yes. Your information is used solely to calculate your electricity savings and is never shared with third parties.

    What if the calculator shows little or no savings?

    Then we will tell you honestly. Our reputation is built on long-term trust, especially with expats and second-home owners in Spain. If we can’t improve your situation, we won’t recommend switching.
