Changing electricity companies may seem like a simple task, but it often leads to hasty or ill-informed decisions that directly affect your bill.

From Nordy, we explain the most common mistakes that are made when choosing a supplier in Spain and how you can avoid them to avoid overpaying.

1. Not comparing energy prices properly

One of the most common mistakes is to choose without comparing. It is not enough to look at the lowest price of electricity on the market or at an attractive promotion.

Many times the offers include temporary discounts that expire after a few months, leaving a much more expensive tariff than it seemed at the beginning. In addition, some companies may promote prices without clearly including other fixed charges, which can distort your perception of the real cost.

Remember all these final energy price factors when making comparisons, checking in detail the price per kWh and the contracted power.

2. Not checking the small print of the contract

Signing without reading the contract carefully can have unpleasant consequences. Some companies include commitments of permanence or additional services that raise the final cost without you realizing it.

In addition, there are marketers that modify their conditions over time. It is important that before signing, you demand that all the conditions are clearly explained to you.

At Nordy we make sure that your contract is clear and without surprises due to hidden or not very detailed information.

Our team accompanies you throughout the process so that you understand every detail before making a decision. In addition, all our rates are transparent, with no hidden charges and no permanence or commitments.

3. Choosing a tariff that does not suit your consumption

Every home and every customer has different energy consumption habits. Therefore, choosing a tariff that does not adapt to your habits can cause you to miss out on savings opportunities. There are different types of tariffs, so the ideal is to know your needs well and analyze which one best fits your lifestyle.

At Nordy we offer you different types of tariffs so that you can choose the one that best suits your needs:

24H tariff: With this tariff, you maintain a fixed price of electricity throughout the day.

  • It is an ideal option if you prefer stability and control in your energy expenses.
  • Ideal to have peace of mind during the hours you enjoy your home.
  • If you do not want to worry about the hours when you do certain tasks that incur a possible high energy consumption, such as using the washing machine.

Market Rate: The price of electricity varies according to the market, which has determined prices at certain times of the day.

  • This rate allows you to take even more advantage of the times when energy prices are lower and thus save on what you pay for your consumption.
  • This rate is quite relevant if you have the possibility to be flexible in terms of the hours you use your appliances and enjoy your home.

4. Contracting a power that does not correspond

Something important to bear in mind is that the contracted power determines the maximum amount of energy you can use simultaneously.

Contracting more power than necessary implies paying a higher monthly fixed cost, while contracting much less than you need can lead to supply cuts or penalties for exceeding the limit.

Therefore, reviewing and adjusting this aspect is not only key to avoid inconveniences and surprises in the future, but also to optimize what you pay for your energy consumption.

Remember that the price of electricity is the result of many factors: type of tariff, contract conditions and amount of consumption. Comparing, informing yourself and checking the details can help you save much more than you imagine.
