Important update, July 2026: do not start a new Holaluz contract
In July 2026 Spain’s Ministry for the Ecological Transition (MITECO) opened proceedings to withdraw Holaluz’s licence to operate as an electricity supplier, published in the BOE around 19 July, after Holaluz fell behind on network access tolls (peajes). Its shares have been suspended from trading. This is the opening stage, not a final decision, and Holaluz has a ten-business-day window to respond. But if the licence is withdrawn, Holaluz’s roughly 144,000 electricity customers would transfer automatically to a reference supplier, a regulated arm of Endesa, Iberdrola or Naturgy.
Our read: this is not the moment to switch to Holaluz. If you are already a customer, your supply is not at immediate risk and you would be moved to a reference tariff rather than cut off, but it is worth watching and keeping your bills. The review below predates this and is left for reference. Confirmed against MITECO and CNMC reporting, July 2026.

Key Takeaways
- 100% green energy, free market only. Holaluz supplies exclusively renewable electricity and operates in the free market — no PVPC, no bono social discount available.
- English support is reader-reported, and we are verifying it. Readers have told us they reached English-speaking agents on 900 64 92 92 (Mon–Fri 9am–7pm). Holaluz does not itself publish an English-language commitment, so treat this as reader feedback we are checking with live calls (July 2026).
- Solar is their strongest card. Holaluz handles installation, grid connection, surplus compensation, and a “virtual battery” for credits — end-to-end for expats who want solar without navigating multiple contractors.
- Not the cheapest supplier. Tariffs are competitive but not the lowest available. Budget-first shoppers will likely find better rates elsewhere.
- Billing complaints are real. Readers have reported payments not processing correctly, followed by unexpected late fees. Worth knowing before you switch.
- Best for: Environmentally motivated expats, especially those considering or already running solar panels.
Holaluz is a Barcelona-founded electricity supplier that has built a reputation among Spain’s English-speaking expat community — partly for its renewable credentials and partly because readers report being able to speak to someone in English. That matters more than it might sound when you’re trying to decipher a Spanish electricity contract for the first time.
This review covers what Holaluz offers, what their tariffs look like in 2026, what readers have reported about their experience — including the frustrations — and who they’re actually the right fit for.
What Is Holaluz?
Founded in Barcelona in 2011, Holaluz is one of Spain’s prominent renewable energy suppliers. They supply electricity sourced 100% from renewable sources — solar, wind, and hydro — and have positioned themselves as a tech-forward alternative to the big legacy utilities.
They operate exclusively in the free market (mercado libre). This means:
- No PVPC (the regulated indexed tariff).
- No bono social (the discounted rate for vulnerable households).
- Pricing is set by Holaluz, not the CNMC regulator.
If you’re eligible for — or actively want — the bono social or PVPC tariff, Holaluz cannot help you. You’d need a comercializadora de referencia like Endesa or Naturgy for that.
For everyone else in the free market, Holaluz is a credible option worth evaluating honestly.
Holaluz Tariffs in 2026
Holaluz offers two main tariff structures:
Flat Rate (Tarifa Fija)
A single price per kWh regardless of when you consume. This is the simpler option — no clock-watching, no shifting your washing machine to off-peak hours. In early 2026, flat rate prices from Holaluz typically sit in the range of €0.13–€0.16/kWh for the energy component, plus a fixed power charge (término de potencia) based on the contracted power level (kW).
Note: electricity prices in Spain fluctuate with energy market conditions. Check Holaluz’s website directly for the current rate before any decision.
Time-Differentiated Tariff (Discriminación Horaria)
Three time bands — peak (punta), flat (llano), and off-peak (valle) — with different prices per kWh. Off-peak hours (typically midnight to 8am) can drop to €0.07–€0.09/kWh, which benefits households running pool pumps, air conditioning, or appliances overnight. Peak rates are correspondingly higher.
The time-differentiated tariff tends to reward expats with flexible consumption habits — particularly relevant on the Costa del Sol where pool pump schedules and air conditioning loads are significant costs.
What’s Not Included in the Energy Rate
Like all Spanish electricity bills, Holaluz tariffs are subject to additional regulated charges: distribution network access (peajes de acceso), electricity tax (Impuesto sobre la Electricidad, currently 5.11%), and VAT (IVA). These apply regardless of supplier. See our guide to Spanish electricity tariffs for a breakdown of what each line on your bill means.
Solar Panels: Holaluz’s Strongest Offering
If you’re considering solar panels on your Spanish property, Holaluz’s integrated solar package is worth serious consideration. They handle:
- Installation of panels and inverter
- Grid connection and surplus registration with the distributor
- Surplus compensation built into your supply contract
- The “virtual battery” — excess generation credits carry forward month-to-month rather than expiring
For an expat unfamiliar with Spain’s solar permitting process, the single-contractor model removes a significant administrative burden. Getting surplus compensation set up correctly in Spain involves paperwork with your distributor (Endesa Distribución, Iberdrola Distribución, or similar depending on your location) — Holaluz manages this on your behalf.
The virtual battery concept is particularly useful in Andalusia’s seasonal pattern: generate surplus in spring and summer, draw down credits in autumn and winter.
That said, expat community feedback suggests the after-service on solar installations has been uneven. Readers have reported monitoring systems going offline and slow response times from Holaluz’s technical team to investigate or fix the issue. If your inverter monitoring stops working, you may be waiting longer than you’d like for a resolution.

English Language Support
This rests on reader reports rather than anything Holaluz states about its own service, and we are verifying it with live calls in July 2026.
Phone: 900 64 92 92 (Monday–Friday, 9am–7pm). English-speaking agents are available. Readers report being able to work through billing queries and contract questions in English without being transferred repeatedly.
Website: Available in English. Signing up, managing your account, and reviewing your tariff can all be done without Spanish language skills.
App: The Holaluz app is functional and available in English. It tracks consumption data and, for solar customers, shows generation and feed-in figures alongside grid draw. Readers find it useful for understanding usage patterns, though some report the app occasionally shows delayed or missing data.
The caveat: wait times can be long. Readers have reported spending extended periods on hold when calling during busy periods. If your query is urgent — a billing dispute, a payment issue — getting through may take patience.
Honest Assessment: What Readers Report
What Works Well
- The green energy commitment is genuine. Holaluz holds the necessary guarantees of origin for renewable supply. If environmental credentials matter to you, they’re not greenwashing.
- English support is real. Multiple readers have confirmed successful English-language interactions for contract changes and billing queries — not just a tick-box on the website.
- Transparent communication. Tariff changes and contract terms are communicated clearly. Readers report fewer surprise bill increases compared to some legacy suppliers.
- Trustpilot rating of 4.1/5 across 8,200+ reviews suggests broadly positive customer experience, though review averages inevitably mask variance.
What Readers Have Complained About
- Billing failures leading to late fees. Readers have reported situations where direct debit payments did not process correctly — and then received late payment charges as a result. If this happens to you, it requires proactive chasing to resolve.
- Solar monitoring going offline. After installation, some readers report their monitoring dashboards going dark. Holaluz’s response to fix this has been described as slow.
- Upselling toward solar. Readers who simply wanted to switch electricity supplier report being actively pushed toward the solar installation package during the signup process. If you only want supply, not solar, be clear about this early.
- Customer service queues. English support exists, but reaching someone can involve significant hold times, particularly during peak periods.
- Not the cheapest option. Comparison tools consistently show cheaper per-kWh rates from other free market suppliers. The English support and solar integration come at a small premium.
Who Holaluz Is Right For
Holaluz makes most sense for:
- Environmentally conscious expats who want confirmed renewable supply and are willing to pay a small premium for it.
- Expats considering or already planning solar installation — the integrated package reduces administrative friction considerably.
- Those who need English-language support and are willing to pay a modest premium for the confidence that entails.
Who Should Look Elsewhere
Holaluz is not the right choice if:
- You’re primarily focused on the cheapest available rate. Other free market suppliers and comparison tools will likely beat Holaluz on pure price.
- You need the bono social discount or want PVPC pricing — Holaluz doesn’t offer either.
- You want a combined gas and electricity package — Holaluz is electricity only.
- You’ve had unreliable solar monitoring and need fast technical response — the after-service track record on solar is mixed.

How Holaluz Compares to the Big Utilities
Spain’s three largest suppliers — Endesa, Iberdrola, and Naturgy — are all comercializadoras de referencia as well as free market players. They offer PVPC and bono social options that Holaluz cannot match. For expats who want those regulated products, the big three are the only route.
In the free market, Holaluz’s main advantages over the big utilities are the English language support, the renewable energy focus, and the solar package. Their disadvantages are pricing (comparable to the big utilities’ green tariffs, but not the cheapest in the market) and the wait times when things go wrong.
Summary
Holaluz is a credible electricity supplier for expats in Spain, particularly those who value green energy, English support, or an integrated solar package. They’re not the cheapest option and the after-service experience for solar customers has been inconsistent. But for an expat who wants the confidence of English-language communication and doesn’t need PVPC or bono social, they represent a genuinely reasonable choice.
Go in with realistic expectations: the support is real, but it takes time. The billing system has known issues — monitor your direct debit confirmations. And if you’re considering solar, ask specific questions about monitoring support before committing.
Frequently Asked Questions
Does Holaluz offer PVPC or the bono social in Spain?
No. Holaluz operates only in the free market (mercado libre). They do not offer PVPC (the regulated indexed tariff) and cannot apply the bono social discount. If you’re eligible for the bono social or want PVPC pricing, you need a comercializadora de referencia such as Endesa, Naturgy, or Iberdrola.
Is Holaluz’s English support genuinely useful for expats?
Readers who have used it confirm the support is real — not just a website language option, but actual English-speaking agents available on the phone (900 64 92 92, Mon–Fri 9am–7pm). Wait times can be long during busy periods, but when you get through, queries are typically handled in English without needing to speak Spanish.
What happens to surplus solar generation with Holaluz?
Holaluz operates a “virtual battery” system where surplus generation credits are carried forward month-to-month rather than expiring at the end of each billing cycle. This suits Andalusia’s seasonal pattern well — summer surplus offsets winter grid costs. The compensation rate is tied to market prices and is set out in your contract.
What are the main complaints about Holaluz from expats?
Readers have reported three main issues: billing payment failures followed by late fees; solar monitoring systems going offline after installation with slow technical response; and long wait times when calling customer service. The billing issue in particular has caught some customers off guard — it’s worth confirming each payment has processed rather than assuming it will.
Is Holaluz cheaper than Endesa or Iberdrola in Spain?
Not reliably. Holaluz’s tariffs are competitive but sit in a similar range to the big utilities’ green/free market rates. You can typically find cheaper per-kWh rates from other free market suppliers. If price is your primary concern, use a comparison tool and check multiple options before deciding.
Can Holaluz supply only electricity, without the solar package?
Yes — electricity supply and solar installation are separate products. Some readers report being steered toward the solar package during signup, but you can sign up for electricity supply only. Be explicit about this if you don’t want solar, as the sales process does push the combined option.
