Before you switch electricity provider, find out what is actually making the bill high
A Spanish electricity bill can be expensive for several different reasons. The tariff may be wrong. The contracted power may be too high. The provider may have added services you do not need. Or the bill may be normal, but your usage timing is working against you.
This check uses the numbers from your bill to identify the real problem and give you one conservative next step: stay put, compare a fixed offer, review PVPC, reduce contracted power, remove add-ons, or get a human review before doing anything.
Use this if your bill feels wrong but switching feels risky
The cheapest-looking kWh rate is not always the cheapest contract. Many Costa households overpay because of fixed power charges, maintenance add-ons, unclear discounts, permanence clauses, or a contract that no longer fits how the home is used.
The output is not a signup link. It tells you what to check before you call the provider, answer a sales offer, or move away from your current contract.
- Retired or semi-retired residents: check whether a low-usage home is being dragged up by standing charges or add-on services.
- Second-home owners: check whether you are paying too much fixed power for a property that sits empty part of the year.
- Families and year-round households: check whether usage pattern, tariff type, or AC-heavy months change the answer.
- Property owners and landlords: check the bill before passing costs to a tenant, accepting a provider pitch, or changing contract terms.
What you will get
- The likely reason the bill is high: tariff, power, services, timing, or unclear contract terms.
- A conservative recommendation: stay, switch-check, PVPC-check, reduce power, remove services, wait, or manual review.
- An estimated monthly impact range where the source data is fresh enough to support one.
- The specific checks to make before switching provider.
- Warnings when the bill should not be handled by a self-serve calculator.
Upload the PDF bill or enter the fields manually
The fastest path is to upload a digital PDF bill. The checker reads it in memory, prefills the bill fields it can find, and asks you to check the highlighted values before the recommendation runs. If the bill is a scan, photo, password-protected file, or too large, use manual entry instead.
The checker does not store the raw PDF, raw extracted text, CUPS, DNI/NIE, IBAN, payment reference, or full address. It stores only the confirmed bill fields and pseudonymous case metadata needed to read the result back.
- Digital PDF bill up to 4 MB, or manual entry from the bill.
- Total kWh and, if shown, P1/P2/P3 kWh.
- Contracted power in P1 and P2.
- Energy term, power term, meter rental, electricity tax, IVA, discounts, services, and total bill.
- Market type if known: PVPC, fixed, indexed, or unknown.
- Permanence or penalty status if the provider shows one.
What the result means
The result is a conservative diagnostic, not a provider signup instruction. Named fixed-offer candidates require a same-day price and clause check before anyone switches.
Reference assumptions last verified 20 July 2026. IVA at 21% and the electricity tax at 5.11% apply to June and July bills, and no August reduction was triggered under Real Decreto-ley 18/2026: June’s electricity CPI rose 6.0% year on year, below the 15% threshold the law requires. Market reference: the regulated PVPC price averaged €0.1453/kWh over the 30 days to 19 July 2026, up 16.3% on the previous 30 days.
