At Evergreen Eléctrica, we have recently received reports from several customers about suspicious phone calls from people claiming to represent electricity suppliers.
These callers often say that your electricity contract is about to expire, that you are going to lose your current tariff or discounts, or even that your supplier is closing down. Their goal is usually to persuade you to provide personal information or authorise a switch to another electricity company without fully understanding what is happening.
Unfortunately, these scams have become increasingly common across the Spanish energy sector. For homeowners, expats and international property owners, they can be particularly confusing because the Spanish electricity market works differently from many other countries.
That’s why it’s important to know how these scams work and how you can protect yourself.
How do these scams usually work?
Most fraudulent calls follow a similar pattern. The caller tries to create a sense of urgency, making you believe that immediate action is required. They may claim that:
- Your electricity contract is about to expire
- Your current tariff or discount will be cancelled
- Electricity prices are increasing unless you accept a new offer immediately
- Your supplier is no longer operating
- They need to “verify” your contract details
Sometimes they even mention your address or basic information to make the call sound more convincing. The objective is to gain your trust before asking for personal or contract information.
Does an electricity contract in Spain suddenly expire?
One of the most common statements used during these calls is that your contract is about to end and must be renewed immediately. In most cases, this is misleading. If there are changes to the conditions of your electricity contract, your supplier must communicate them through the appropriate channels and in accordance with the terms of your agreement and Spanish regulations.
You should be cautious if someone pressures you to make an immediate decision over the phone. Legitimate companies do not rely on fear or urgency to persuade customers to change supplier.
Be careful when someone asks for your personal information
Fraudsters often try to collect information that could be used to process a supplier switch or impersonate you during future communications. They may ask for your full name; passport or NIE number; bank account details; your electricity bill; your CUPS number (the unique identification code for your electricity supply); or verification codes received by SMS.
If you were not expecting the call, you should never share this information. Even if the caller sounds professional or already knows some details about you, it is always safer to verify their identity independently.
How Evergreen Eléctrica contacts its customers
At Evergreen Eléctrica, transparency is one of our core values. We will never contact you unexpectedly to pressure you into changing your contract. And we will never ask you to provide passwords, online banking credentials or sensitive financial information over the phone.
If we contact you regarding an existing contract or a request you have already made, we will clearly identify ourselves and explain the reason for the call. If you are ever unsure, you can simply end the conversation and contact us through our official customer service channels.
Warning signs that a call may be fraudulent
Although every situation is different, there are several common warning signs. You should be cautious if the caller:
- Pressures you to make an immediate decision
- Claims you must act today to avoid losing your electricity supply or discounts
- Asks for personal or banking information without a request from your side
- Requests your CUPS number or asks you to send a copy of your electricity bill
- ends links by SMS or WhatsApp asking you to confirm information
- Refuses to let you verify their identity
Legitimate customer service representatives understand if you prefer to verify information before making any decision. Fraudsters usually try to prevent that.
What should you do if you receive a suspicious call?
If you believe a call may not be genuine, the safest option is to end the conversation politely. Do not provide personal information, bank details or contract documentation. Instead, contact your electricity supplier directly using the official telephone numbers or email addresses published on their website or shown on your electricity bill.
Never rely on the contact details provided by the caller. If you receive an SMS or WhatsApp message following the call, avoid opening links or downloading files until you have confirmed that the communication is legitimate.
If you think you may have shared information
If you realise afterwards that you may have provided personal information during a suspicious call, it is important to act quickly. Contact your bank if financial information has been disclosed and inform your electricity supplier immediately so they can check whether any unauthorised changes have been initiated.
Taking action promptly can help prevent further problems.
A special reminder for holiday homeowners
Many of our customers own holiday homes or second residences in Spain and spend part of the year abroad. Fraudsters sometimes target these homeowners because they may be less familiar with Spanish electricity regulations or unable to visit the property immediately.
If you receive a call while you are outside Spain, do not feel pressured to make decisions immediately. A legitimate issue with your electricity contract can always be verified later through your supplier’s official channels. Taking a few minutes to check the information is far safer than making a rushed decision.
Our commitment to transparency
At Evergreen Eléctrica, we believe that trust is built through honest communication. We never use misleading sales tactics or false claims to persuade customers to switch suppliers. Our priority is to provide clear information, personalised advice and transparent customer service in both English and Spanish.
If you ever receive a call claiming to represent Evergreen and you are unsure whether it is genuine, please contact us directly before sharing any information. We will be happy to verify the communication and help you protect your electricity contract.
Frequently Asked Questions
Can someone switch my electricity supplier without my permission?
Switching electricity supplier in Spain requires a valid contracting process. If you believe someone has tried to change your supplier without your consent, contact your electricity company immediately so they can check the status of your contract and advise you on the next steps.
What is a CUPS number and why should I keep it private?
The CUPS (Código Universal del Punto de Suministro) is the unique identification number for your electricity supply in Spain. While it is not enough on its own to change your contract, it is an important piece of information used during many electricity-related procedures. You should only share it with trusted companies when you have initiated the process yourself.
How can I verify that I’m really speaking to Evergreen Eléctrica?
If you have any doubts, simply end the call and contact us using the telephone numbers, WhatsApp or email addresses published on our official website. We’ll be happy to confirm whether the communication is genuine.
I own a holiday home in Spain. Am I more likely to receive these calls?
Holiday homeowners and international property owners can sometimes be targeted because scammers assume they may be unfamiliar with the Spanish electricity system or unable to visit the property immediately. Never feel pressured to make a decision over the phone, especially if you are outside Spain.
What should I do if I have already shared my personal information?
If you think you may have provided personal or banking details during a suspicious call, contact your bank immediately if financial information was involved. You should also get in touch with your electricity supplier as soon as possible so they can check whether any unauthorised changes have been requested.

Telephone scams in the energy sector continue to affect thousands of consumers every year. Being aware of the warning signs is the best way to avoid becoming a victim.
