Endesa Reviews 

Extremely dishonest company. Never seen this before.
I moved into a flat that had an Endesa contract, I moved over to Octopus but Endesa kept on calling to keep the account and no matter how many times I said no they still lied and took back the account, without even having my details, they keep on sending the invoice to the old account holder name, proof they don't even know me.

Do NOT get ENDESA! This is by far the worst company I've ever dealt with! I have both gas and light, as well as the maintenance for the water heater for two apartments with Endesa. My water heater in one apartment was not providing hot water. I called the maintenance line at Endesa I was told 3 hours or less for a technician to come. It has been A MONTH, I called more than 55 times, and they will just keep telling you that someone is on the way. ALL LIES. My water heater ended up bursting and flooding my entire kitchen, breaking ALL equipment in my kitchen. I called and explained the full situation, I was transfered from one department to the next. Operators were rude, and were not working in a quiet setting so you could hear people screaming behind them. I had to leave the apartment with my daughter at 3am due to the fact that we had to close the water valve of the apartment because water was pouring out of the water heater. This negligence is unaccetable. In endesa you can pay additionaly for a service and it will never get rendered. I also claimed the money that this is going to cost me in reparations and in bookings, I had to harass and call them and be transferred to many departments to finally get an answer. They told me they made the claim with the wrong department and needed to make a new one. WORST COMPANY EVER. Take your money and go with a more reputable company whose customer services have positive reviews.

there are some server errors

Great help at the store from a lovely lady, who went out of her way to help us

The changeover was smooth but my reason for changing supply was to reduce my bill as promised by the Endesa representative.
My bill is now higher than with Energia XXI
Very unhappy

Since the beginning of 2025, I’ve consistently received incorrect invoices from Endesa. The issues include: 1) Incorrect consumption amounts; 2) Incorrect invoicing periods listed on the bills; 3) Delays in issuing invoices—my most recent one wasn’t sent for over two months.

This raises serious concerns about the accuracy and reliability of their billing system.

Unfortunately, customer support adds to the frustration. English-speaking assistance is nearly non-existent, and in multiple cases, calls have simply been cut off without resolution. You can try calling again—if you have another 30–50 minutes of free time. (Ideal for a long coffee break… or a dose of antidepressants. Disclaimer: not medical advice!) 😅

If you're looking to add some unpredictability and tension to your well organized and boring life, Endesa might just be the partner for you! Otherwise, I’d recommend proceeding with caution.

I've been getting Estimated bills for the past 6 months. I've been trying to resolve the matter with resolution. I have a smart meter, so this shouldn't be happening. I'm now looking for another provider.

Ultimamente, estais haciendo facturació es raras, y ya llevo un par de meses con dos facturats mensuales de luz

There have been many problems with the invoices / some being sent multiple times and others being paid more than once. This means that it is very difficult to ascertain as to whether invoices have been paid, not paid and leads to a feeling of chaos and inefficiency at Endesa

It is difficult to contact Endesa, I was charged twice but can't get thru

Condiciones favorables y un trato exquisito por los dos tramitadores que me atendieron

I like the rewards but I was to receive 10eruo in a reward and it was much less .the price is ok but never a regular date if your bill

Good luck nice

Could not contact an operative to discuss billing queries

bad english communication for foreigners
and more than month to obtain the 3fasic for my builder !?

Ora fantastic. All clear and all available in digital form in app

In general everything is good but I do not all way receive the bills by email which can make it difficult as we have four accounts.

Your advisor for changing tariff was very helpful
