1. Save money from hidden charges & clauses

What they usually do not tell you is that you pay for the kilowatt-hour at the price set by your supplier, plus the adjustment clause, which depends on the procurement cost and the price per kilowatt-hour.

Some providers advertise only the price per kilowatt-hour, without mentioning the fluctuation mechanism that will be applied later. The result? The final supply price differs significantly and you end up paying more than you thought.

Maybe it is time to act? Look for a new electricity plan with lower charges and no hidden terms.

2. I Am Going to Switch Electricity Provider: What Should I Watch Out For?

The changes to electricity tariffs in force since 1 January 2024 make it important to choose the right tariff “colour” and the corresponding provider.

1. Orange tariffs are ideal for consumers who want to benefit from energy market fluctuations in real time, offering the possibility of lower prices. They are also suitable for those with photovoltaics, but they carry higher risk and require the installation of a smart meter
2. Blue tariffs offer stability and protection from price swings, without an adjustment clause, while green tariffs have a “locked” price that is affected once a month by the market.
3. The yellow tariff currently stands out for the lowest prices.

3. The process of switching electricity provider

Today, switching electricity provider is simple and fast, giving consumers the ability to choose the most advantageous package for household or business electricity. The main criterion for choosing a provider is its pricing policy, as well as the offers and services it provides.

Before you submit an application, it is good to know what is included in your bill: the charges from the provider, the regulated charges owed to third parties and any additional perks.

It is also useful to have a picture of the annual electricity consumption of your household or business, as well as of its seasonality, based on recent bills.
