Steps to switch electricity providers
Switching electricity companies is not immediate, your previous retailer will need to close the billing period, so the switch can take up to 20 business days.

1. Compare rates from different suppliers
The first step in switching electricity providers is to analyze the available rates in the market. Check offers from various suppliers to find the one that best fits your consumption and budget, keeping in mind that the average cost of switching is around 175 €. Use online comparison tools to evaluate prices and conditions in minutes.

2. Request a personalized quote based on your consumption
Contact the electricity suppliers you're interested in and request a personalized quote based on your annual electricity consumption. This analysis will show you the actual savings you'd achieve, with switching costs typically ranging from 50 € to 150 € at the standard level. Have your latest bill handy to provide accurate consumption data.

3. Review the contract terms and conditions
Before confirming the switch, carefully read all terms of the new contract with the supplier. Check for early termination penalties, minimum lock-in periods, and any additional charges within the 50 € to 300 € range depending on your tariff type. Don't hesitate to ask for clarification on any unclear clauses.

4. Submit a switch request to your new supplier
Formally submit your switching request to the new electricity supplier, who will handle all administrative procedures with your current provider. This process is free of charge and the new company is responsible for coordinating the necessary steps. You can submit your request by phone, online, or in person at the supplier's offices.
What can change your final price
Even similar projects can end with different budgets. These are the factors that most often push costs up or down.
Your current contracted power
The power of your installation (measured in kW) will determine the cost of your new rate. Higher power levels mean higher monthly fees with most electricity suppliers.
Type of rate chosen
The final price varies significantly depending on whether you choose a fixed rate, indexed rate, time-of-use pricing, or flat rate. Time-of-use rates are usually more economical if you adjust your consumption to cheaper time slots.
Electricity supplier and available offers
Each electricity company offers different prices and promotions. Comparing between Iberdrola, Endesa, Naturgy, Holaluz or Podo can result in savings of between 100 and 300 euros per year depending on your consumption.
Estimated annual consumption
Your energy consumption history is essential to calculate your total annual cost. A household consuming 3,000 kWh/year will pay significantly less than one consuming 5,000 kWh/year.

Prices can vary significantly depending on the type of rate chosen. Thus, you can find prices ranging from 0.13 €/kWh to 0.30 € kWh for consumption. Also, the price paid for power can vary significantly, although on average they can be between 0.03 kWh per day and 0.12 €/kW per day.
Regulated market
- With fixed price throughout the day: the kW remains unchanged.
- With hourly discrimination: the electricity price varies according to off-peak, peak, and standard hours.
- Flat rates: the user pays a fixed amount on the bill for a year. The calculation is based on historical consumption. But if the established consumption limit is exceeded, the price paid for electricity is high.
To switch electricity companies, whether they belong to the open market or the regulated market, you will need to provide certain information and documentation. It is mandatory; if there are errors or omissions, the switch will not proceed. What is required is the following:
- Completed and signed request form by the account holder or their duly identified representative.
- The request must include identifying data of the account holder and location of the supply point, CUPS and banking details for bill domiciliation. It is also necessary to indicate the power you wish to contract.
- A photocopy of the account holder's identification document is usually requested, and for new properties, also the electrical certificate.
- In some cases, the company may request a document proving ownership or a rental contract.
