Oxxio vs Eneco 2026: the same green energy, sold two ways
One owner, one renewable supply chain, and only one of them charges extra for it
The short answer
Oxxio belongs to the Eneco group and draws on the same renewable supply chain, so the electricity arriving at your home is physically the same whichever you sign with. What differs is how the green part is priced.
Oxxio includes 100 percent green electricity as standard on every contract type. It is not an upsell and not a tier. Eneco has a genuinely strong renewable portfolio in HollandseWind and solar, but its greenest options carry premium pricing. Same energy, one of them charging you extra to feel good about it.
Bottom line: take Oxxio if green matters and you read Dutch, since you get it included rather than as a paid upgrade, plus the unusual Hybride contract that fixes gas while leaving electricity variable. Take Eneco if you want partial English support, Toon thermostat integration, or the reassurance of one of the three largest suppliers.

The green pricing difference
This is the whole reason to read a comparison of these two. Eneco built its reputation on sustainability and offers HollandseWind, Dutch wind power, alongside solar. Those are real products with real certificates behind them. But the greenest options sit at premium pricing, which is standard practice across the Dutch market.
Oxxio, drawing on its parent's supply chain, simply includes 100 percent green electricity on every contract it sells. Fixed one-year, fixed three-year, variable, dynamic: all of them, at no extra charge and with no greener tier to upgrade into.
| Attribute | Oxxio | Eneco |
|---|---|---|
| Green electricity | 100% standard on every contract | HollandseWind and solar options, premium priced |
| Supply chain | Shared with Eneco | Own renewable portfolio |
| Scale | Around 250.000 customers since 2001 | Around 2 million households |
| Ownership | Eneco group | Mitsubishi Corp and Chubu Electric since 2020 |
What green actually means on a Dutch energy contract
No supplier can route specific electrons to your house. Green contracts work through certificates of origin, which guarantee that a matching amount of renewable energy was fed into the grid. Dutch-sourced certificates, such as those behind HollandseWind, are generally regarded as more meaningful than imported ones. This is worth understanding before paying a premium for a label, and we cover it further in our energy and heating guide.

Oxxio Hybride, and who it suits
Most Dutch contracts ask you to fix both gas and electricity or leave both variable. Oxxio Hybride splits them: gas at a fixed rate, electricity at a variable rate. That combination is genuinely rare here, and it solves a real problem.
Gas is the harder half to predict. Dutch winters drive heating demand, most housing stock still runs on gas central heating, and a cold snap can move your bill sharply. Electricity is steadier and has more room to fall when wholesale prices drop, particularly as more renewable capacity comes online. Fixing the volatile half while staying exposed to the half more likely to fall is a defensible strategy rather than a gimmick.
Hybride suits you if
- You heat with gas and want that cost predictable
- You have solar panels, so your net electricity draw is small
- You think electricity prices are more likely to fall than gas
Skip it if
- You live in a fully electric home with a heat pump and no gas connection
- You want total certainty and would rather fix both
- You can shift usage by the hour, where a dynamic tariff pays better
Why neither offers cashback
Neither Oxxio nor Eneco runs a headline welcome bonus, which sets them apart from most of the Dutch market. For comparison, Budget Energie offers up to €500, Essent up to €400 and Energiedirect up to €350, and Vattenfall up to €250.
No bonus is not the same as bad value
A welcome bonus is paid once. The per-kWh rate and the standing charge apply every day of the contract. Suppliers that lead with large cashback often carry higher underlying rates, and the bonus quietly funds itself over your first year. A supplier with no bonus and a competitive tariff can easily be the cheaper choice by month eight.
Because these two compete purely on rate rather than on a sign-up sweetener, the comparison is more honest than most. Run your own postcode and expected consumption through the energy comparison tool. Dutch rates vary by region and change often, which is why we do not publish per-kWh figures that would be stale within weeks.
Service, apps and English
Eneco is the more approachable of the two for a non-Dutch speaker, though neither is genuinely bilingual.
Eneco
- Partial English handling
- Toon smart thermostat integration
- Around 2 million households, one of the big three
Oxxio
- Strong in-house app for consumption and contract changes
- 8.4 out of 10 rating on the switching experience
- No English at all, limited phone support, app and chat first
If English service is the deciding factor, neither of these is your answer. Coolblue Energie is the Dutch supplier that reliably provides it, covered in Vattenfall vs Eneco vs Coolblue Energie. You will need a BSN and a Dutch bank account either way.

Which one should you take
Take Oxxio if
- Green energy matters to you and you would rather not pay a premium for it, since Oxxio includes it on every contract.
- The Hybride contract fits your situation: gas heating you want fixed, electricity you are happy to leave variable.
- You manage everything by app and read Dutch comfortably.
- You value a smooth switching process, where Oxxio rates 8.4 out of 10.
Take Eneco if
- You need at least partial English, which Oxxio does not offer at all.
- You want Toon thermostat integration rather than app-only control.
- You specifically want Dutch-sourced HollandseWind and are willing to pay the premium.
- You prefer dealing with one of the three largest suppliers in the country.
Consider neither if: a welcome bonus is what you are after, since neither offers one, or if English service is essential. Compare the wider market in our Dutch energy providers comparison.

Frequently asked questions
Are Oxxio and Eneco the same company?
Oxxio is owned by the Eneco group, which has itself been owned by Mitsubishi Corporation and Chubu Electric Power since 2020. Oxxio shares Eneco's renewable supply chain, so the electricity reaching your home comes from the same sources either way. Oxxio has operated since 2001 and serves around 250.000 customers; Eneco is one of the three dominant Dutch suppliers with around two million households.
Which one is actually greener?
Neither, in physical terms, because they draw on the same renewable supply chain. The difference is how it is sold. Oxxio includes 100 percent green electricity as standard on every contract type, with no upsell. Eneco offers strong renewable products such as HollandseWind and solar, but its greenest options carry premium pricing. If green energy is your priority, Oxxio gives you the same thing without the surcharge.
What is the Oxxio Hybride contract?
Oxxio Hybride fixes your gas rate while leaving your electricity on a variable rate. That combination is rare in the Dutch market and it suits a specific situation well: gas is the harder cost to predict in a Dutch winter, while electricity prices have more downside if the market falls. It lets you protect the volatile half of your bill without locking in the other half.
Does either offer a welcome bonus?
No. Neither Oxxio nor Eneco runs a headline welcome cashback, which is unusual in the Dutch market. Budget Energie offers up to €500, Essent up to €400 and Energiedirect up to €350. That absence is not automatically bad, because a bonus is a one-off while the tariff applies all year, but it does mean you should compare these two purely on rates and product.
Can I get English-language service from either?
Eneco offers partial English, Oxxio offers none. Oxxio is Dutch-only across its website and app, with limited phone support and most contact routed through app and chat. Eneco has some English handling but its service is also primarily Dutch. If you need reliable English from sign-up through to billing disputes, Coolblue Energie remains the provider that delivers it.
What is Toon and does it matter?
Toon is a smart thermostat that integrates with Eneco, giving you heating control and consumption insight in one device. It is a genuine advantage if you want hardware rather than just an app. Oxxio counters with a strong in-house app for consumption insight and contract switching, and holds an 8.4 out of 10 customer rating on the switching experience specifically.
Do I need a BSN for either?
Yes, both require a BSN, as do effectively all mainstream Dutch energy suppliers, along with a Dutch bank account for the monthly direct debit. If you have just arrived and have no BSN yet, sort that first. Switching supplier never interrupts your supply, because your regional network operator physically delivers the energy regardless of who bills you.
