Holaluz Reviews 

Not delivering what they promised! A year ago I contracted a solar installation + batteries including backup. But I didn't get the backup installed. I've called this out to them at least 15 times since September 2025. It is September 2026 and still I have no solution, one year after! How hard can it be to deliver a product a customer paid for?

Cirkus !!!!! S....t company !!

IF I COULD GIVE A -5, I WOULD!!! Having a bit of a nightmare with this circus. Cancelled my contract with them due to their incompetence and switched to Iberdrola. They provided grossly incorrect estimated meter data to Iberdrola, costing me over €400. I asked for the actual readings, and they just flipped me the finger! I asked foir a Hoja de Reclamaciones and yet again they just flipped me the finger.

Update: They replied to my review on the 20th to say they would attend to the matter urgently. Today is the 27th and no further word from them.

I purchased solar panels and batteries from this company, promising me no energy bills for the next five years and English-speaking customer support.

They installed the system on a Friday and essentially ran me through the entire installation process in Spanish. Since I’m not an electrician, I had no idea what they were talking about and didn’t understand it either. But what do you expect from a Friday afternoon at 4 p.m.?

After that, the problems began. My electricity started jumping, and my house went without power for several hours. I couldn’t get any customer support, and no one could explain why the batteries weren’t kicking in when the electricity was cut. I couldn’t get any overall support for my installation.

At one point, I managed to get an English-speaking customer service agent. She sent me a PDF in Spanish and said that if I couldn’t restart my installation, I should send her an email, and she would contact someone to come and review it. I’m not an electrician, so I sent an email saying that I couldn’t complete the reset procedure and that I was still waiting. I sent five emails, and I haven’t received a response. I also had two WhatsApp conversations with the technical support agent who sold me the installation. She kept saying that customer support would get back to me, but nothing happened. She even filed an email to customer support, but no one has replied to her. I also have the agent who should be taking care of my installation, and he hasn’t replied to me at all.

So, with all that said, I’m still waiting. The installation went in in October 2025, and we’re March 2026. My house is still jumping, and the installation is potentially not working properly. The batteries still don’t kick in when the house goes off-line, so I wouldn’t recommend this installation.

Updated since 18 March.
Holaluz did organize an electrician to visit the installation that following Friday 20th.
The result the electrician confirmed that only 50% of the installation had been completed. I have a backup that is connected to nothing. I repeat nothing. I have a three phase installation at the back of the house and a mono phase they installed in my electrical box, inside the house, connected once again to nothing. So the installation cannot work properly.

I am still waiting for them to confirm and actually come and install everything properly.

We are now the 12 April… and not even an email from them…

I first reported a problem with our system on the 22 December 2025. Since then, we have made numerous phone calls and sent many emails requesting support to rectify the problem. We get, what seems an automated reply to the emails saying the problem has been logged and support will be forthcoming.
It is now 10th March 2026 and we have still not had any replies or visits scheduled for technical support.
This company is contracted to provide technical support when needed, but nothing is forthcoming. Telephoning Customer Service provides no support whatsoever as they openly admit they have no link to the technical support department. We have also been told that we are entitled to compensation for energy lost but so far, we have received nothing but higher bills, so it means we are actually paying for their malfunction. The Company seems to have no interest in providing an after sales service. We find ourselves with a defunct system and no way of recouping the cost.
We find ourselves with only one option and that it to file a complaint against the company via legal means.
Reporté por primera vez un problema con nuestro sistema el 22 de diciembre de 2025. Desde entonces, hemos realizado numerosas llamadas telefónicas y enviado numerosos correos electrónicos solicitando asistencia para solucionar el problema. Recibimos una respuesta aparentemente automática que indica que el problema se ha registrado y que pronto recibiremos asistencia.
Hoy es 10 de marzo de 2026 y aún no hemos recibido respuestas ni visitas programadas para soporte técnico.
Esta empresa está contratada para brindar soporte técnico cuando sea necesario, pero no lo hace. Llamar al servicio de atención al cliente no ofrece ningún tipo de soporte, ya que admiten abiertamente que no tienen conexión con el departamento de soporte técnico. También nos han dicho que tenemos derecho a una compensación por la pérdida de energía, pero hasta ahora solo hemos recibido facturas más altas, lo que significa que, en realidad, estamos pagando por su mal funcionamiento. La empresa no parece tener interés en brindar servicio posventa. Nos encontramos con un sistema inoperativo y sin forma de recuperar el costo.
Solo nos queda una opción: presentar una queja contra la empresa por vía legal.

Holaluz installed solar panels on my roof, all went well. Sometime, my installation went offline and I noticed this in December. On the 3rd of December I sent an email. On the 10th of December I sent a reminder (as I hadn't received a reply). I received a nondescript reply the same day saying it wasn't their problem (? I replied I don't understand, as I am buying my electricity from them and they installed my solar panels) A MONTH later (13 January 2026) I received an email asking me to reset the installation (which I did, no difference) and if that didn't work to send them photographs of the installation (which I sent them on the 14th of January) On the 23rd of January I sent them a reminder, to date: NO REPLY.

A week ago the case was found and was supposed to be treated with urgency. On 11-02-2026 I have still received no reaction!

I've subscribed a fix price contract where they putted an estimation of 0.00kWh and did not put the fixed price amount inside the contract. After a few months of wandering why my bill was so high I also discovered that the contract has clauses that makes them mandatory for them to have an english version of it shall you request it.

I performed such request through email, inquiring about explanations regarding the estimation they've putted on the contracts, asking for a change in the type of contract. To this day I have not received any answers.

Their FAQ explains that you're supposed to be able to change your type of contract through your personal area, which is a lie, there's no such possibility.

The only way to be in touch with them is through phone with their terrible support that litterally complains about their customers.

They will probably answer this review saying they're sorry and that we can reach them through mail, it's a lie they will not answer. I will block the payment and eventually move to another company.

Great to deal with and the transfer went smoothly

This company and Juan Carlos always do everything with such efficiency, a great company.

Had everything explained exactly as wanted

Have been a happy client for years but lately tried to reach their customer service and there is ZERO response.

Multiple emails and weeks of trying to contact them - completely ignored.

Changing now to another provider.

worthwhile choice

After speaking to endless customer team members and not having electricity for at least 10 days, my electricity came back on. In the meantime, I spoke with a higher manager to explain I would like compensation for the length of time it took to restore my electricity. I did not hear back. Today I was charged 115 EUR for electricity for the month of June. 3rd-12th June the electricity was not installed. 12th-24th June the fuses/meter were switched off as I was out of the country and the electricity was not working. I emailed customer service when I received the bill to ensure rightful compensation and deduction to the bill and unfortunately today the full amount left my account.

Aside from one helpful member of the team, I have had endless negative experiences, phone being put down, not being called back even by the higher management team. I will be putting in a formal complaint.

I came to Holaluz from Endessa when the Endessa website was so awful. On the other hand, Holaluz was quick and easy to use. They communicated in English. The transfer was easy. I haven't paid for electricity since I transferred in January. Although I have yet to hear with details, thewy contacted me about a gizmo so that if the grid goes down, I transfer automatically to my panel electricty.

The service is easy to work with and they communicate well with their clients.

I have not been with you for long enough to make opinio

Great service & efficient

I was a customer at Holaluz for 3 years, never had any issues, made a switch to a competitor with the promise of a cheaper tariff, but that was a mistake. I'm back and very happy with the friendly and quick service! Thank you.

I wanted to change my energy company to this one and wanted to get consultation. I booked the cita for call on Monday 24th 12pm. Nobody even called me. Why do you offer these citas then? If you don't call at booked time? After this I found the site and applied the form "Call me now". They called me back, but my Spanish is not so good for discussing the ways of changing companies. I asked someone who speaks English and the lady said that she will try but after this just dumped my call. And nobody called me back. With this attitude, I would rather choose another company to change. Why should I beg someone to contact me and give me service if it is particularly their job?

P.S They called me after 3 hours. They found person who speaks English, thanks for this. But I already chose another company and still don't understand why nobody called on my booked cita. So I changed rate from 2 to 3.
