1. Why comparing electricity companies matters more than ever
In recent years, electricity bills in Spain have skyrocketed.
With so many changes in the market and offers full of fine print, it is easy to end up paying more than necessary.
Therefore, compare and choose your electricity company wisely. is no longer an option, it is a necessity.
After trying several companies and reading dozens of reviews, I ended up choosing Octopus Energy, and since then my bill went down and the service improved.
In this article I tell you why I think it may also be the best option for you.
2. What is Octopus Energy and why does it stand out from other companies?
Octopus Energy was born in the United Kingdom and has quickly become one of the most reputable electric utilities in Europe. Its philosophy is simple:
100% green energy, transparent pricing and humane customer service.
It has been operating in Spain since 2021, and what I liked the most from the beginning is that they do not try to trap you with complicated contracts or “temporary” discounts”.
Everything is clear, no surprises.
In addition, it has a rating of 4.8 out of 5 on Trustpilot, with thousands of satisfied customers.
This already gives you an idea of the quality of the service.
What caught my attention the most:
- Energy 100% certified renewable.
- Without permanence no penalties.
- Very easy to use App and customer area.
- A trato cercano with real attention by email or telephone.
3. Price comparison: Octopus Energy vs. other companies
To see if it was really cheaper, I compared my consumption with that of other well-known companies:
| Company | Fixed rate (€/kWh) | Permanence | Green energy | Customer service |
|---|---|---|---|---|
| Octopus Energy | 0,137 | ❌ No | ✅ Yes | ⭐⭐⭐⭐⭐ (4.8/5 on Trustpilot) |
| Iberdrola | 0,165 | ✅ Yes | ✅ Yes | ⭐⭐ |
| Endesa | 0,159 | ✅ Yes | ❌ Not always | ⭐⭐ |
| Holaluz | 0,153 | ❌ No | ✅ Yes | ⭐⭐⭐ |
| Repsol | 0,162 | ✅ Yes | ❌ Not always | ⭐⭐ |
💡 Result: in my case, with an average monthly consumption of 300 kWh, I saved between €6 and €10 per month, i.e, more than 100 € per year by simply switching to Octopus Energy.
