The truth is that changing supplier is simple, free and without risk of supply cut-off. You just need to be clear about who you want to contract with and follow these steps.<\/p>\n<h3>1. Choose a new supplier and tariff<\/h3>\n<p>The first thing is to compare and choose the supplier that best suits you. In PROT Energ\u00eda, for example, we are committed to transparent, stable and 100% certified green energy tariffs. <strong>You have to make sure that<\/strong>:<\/p>\n<ul>\n<li>The company is <strong>registered<\/strong> in the official list of marketers.<\/li>\n<li>Offer <strong>clear rates<\/strong>, without fine print.<\/li>\n<li>It allows you to <strong>check updated prices<\/strong> and simulate your invoice.<\/li>\n<li>You can <strong>easily<\/strong> <strong>contact<\/strong> customer service (by phone, email or app).<\/li>\n<\/ul>\n<p>In addition, if you are interested in changing your electricity supplier to one with green energy, make sure it has a <strong>Guarantee of Origin<\/strong> (GoO) <strong>certificate<\/strong> issued by the CNMC.<\/p>\n<h3>2. Provide your information<\/h3>\n<p>If you have already chosen your company, you will have to provide the following information to <strong>formalize the contract<\/strong>:<\/p>\n<ul>\n<li>Full <strong>name<\/strong> and <strong>surname<\/strong> of the holder.<\/li>\n<li><strong>DNI<\/strong> or NIE.<\/li>\n<li><strong>Address<\/strong> of the point of supply.<\/li>\n<li><strong>CUPS<\/strong> code (it appears in any old bill, it is like the DNI of the light point).<\/li>\n<li>Bank details<strong>(IBAN<\/strong>) for direct debit payments.<\/li>\n<\/ul>\n<p>In principle, you do not have to provide the previous contract or a justification for the cancellation of your contract with your current supplier.<\/p>\n<h3>3. We manage the change<\/h3>\n<p>Once the contract is formalized, PROT Energ\u00eda takes care of absolutely everything. You do not have to contact your old company, or perform any additional management. We will only ask you for your details, and as soon as the contract is validated, we will make the change for you.<\/p>\n<p>And the best part? You don&#8217;t have to worry about outages or interruptions. Your supply will continue to work as usual, just at a better rate. In fact, we can analyze your current bill without obligation and offer you a customized estimate. Feel free to <a href=\"https:\/\/protenergia.com\/en\/contact\/\">contact us <\/a>for more information.<\/p>\n<h3>4. Welcome to PROT Energ\u00eda<\/h3>\n<p>Once the changeover is complete, we welcome you to our community of people who, like you, are committed to cleaner, fairer and more transparent energy. You will receive your first bill with us and you will have access to your customer area, where you can consult what you need and resolve any doubts.<\/p>\n<h2>Important considerations when switching to another supplier<\/h2>\n<p>Changing electricity supplier is a simple process, although there are still some <strong>myths<\/strong> out there that often generate doubts. Let&#8217;s resolve it:<\/p>\n<ol>\n<li><strong>Is the power cut off during the changeover? No <\/strong>. The change of supplier does not interrupt the supply at any time. The energy arrives to you in the same way, the only thing that changes is who bills you for it.<\/li>\n<li><strong>Is there any cost for the change? No <\/strong>. The switching process is completely free of charge. If you have a contract with permanence with another company, you should check if they impose penalties for early cancellation, but most current tariffs do not have permanence. We, for example, do not.<\/li>\n<li><strong>Can I verify that the energy is green? Yes <\/strong>. At PROT Energ\u00eda we guarantee that all the energy we supply is certified as 100% renewable, issued by the CNMC. You can check it in each invoice or ask us for the certificates whenever you want.<\/li>\n<\/ol>\n<h2>How many changes of supplier can be made?<\/h2>\n<p><strong>Yes<\/strong>, you can change your electricity supplier as many times as you wish. It is also true that, in general, you do not constantly change supplier, at most once a year.<\/p>\n<p>This way you can <strong>check the evolution<\/strong> of your consumption and evaluate if you need a more stable tariff, a variable tariff, or one with hourly discrimination. Most companies allow you to cancel without penalty, but you should always read the contract conditions carefully. If you are on a tariff without permanence, you can change without paying fees or cancellation costs at any time.<\/p>\n<h2>How long does it take to change electricity suppliers?<\/h2>\n<p>The changeover process <strong>is not immediate<\/strong>, but it is quite <strong>fast<\/strong>, since it takes between <strong>15 and 20 working days from the time the contract is signed<\/strong>. Remember, during this period, you continue to receive electricity with your previous supplier and, once the change is activated, you will receive the bill with your new company. At PROT Energ\u00eda we will inform you of the whole process so that you are always informed. All this period depends on:<\/p>\n<ol>\n<li>Your distributor&#8217;s <strong>billing cycle<\/strong><\/li>\n<li>The <strong>time<\/strong> at which the change is processed<\/li>\n<li>Data <strong>validation<\/strong> by the CNMC and the distribution company<\/li>\n<\/ol>\n","protected":false},"excerpt":{"rendered":"<p>More and more of us want to make conscious decisions to save on our electricity bills and take care of the planet at the same time.
