Remaining on an expired or variable contract can be less competitive than current offers. Review both unit rates and fixed charges when a contract ends; do not assume that switching will always save money. This guide explains the process and the terms to compare.
💡 For a broader overview see our Dutch utilities explained guide: energy, water, gas and waste in one place.
Quick answer: Check the current contract end date and cancellation quote, compare total annual cost using your own consumption, and confirm the new supplier’s switching steps before accepting. A lower headline unit rate does not by itself prove a saving.
How the Dutch Energy Market Works
In the Netherlands you have a free choice of energy supplier (leverancier), while the grid operator (netbeheerder) is determined by where your connection is, and you cannot choose it. The grid operator runs the network that delivers the electricity and gas; the supplier sells you the energy and sets the supply rates.
This split matters because:
- Switching supplier does not change your grid operator or your connection.
- Part of your bill does not depend on the supplier you choose: the grid operator’s charges and the energy taxes. When those rise, a supplier may pass the increase on, even in a fixed contract.
- The supply rates and the supplier’s fixed supply charge are what you compare between suppliers.
Suppliers you will see on a Dutch comparison include:
- Vattenfall (known in the Netherlands as Nuon until 2019)
- Eneco
- Essent
- Greenchoice
- Vrienden van Energie
- Budget Energie and Energiedirect
- Budget Thuis (offers energy alongside internet and mobile)
- Pure Energie, OM
A comparison site or a quote on each supplier’s own website shows live tariffs for your address. Filter by green or grey, fixed or variable, and contract length, and compare the total annual cost.
Why Switching Can Save Money
Suppliers compete for new customers with welcome offers, and the rates you pay on an existing contract are not automatically the lowest rates the same supplier offers today. When a fixed contract ends, check what happens next: the new rates and whether the contract continues as a variable contract.
What decides whether switching pays off for you:
- Your own annual consumption, from your annual statement (jaarafrekening) or your supplier’s app
- The total annual cost of the new offer, including the fixed supply charge
- The value and conditions of a welcome bonus
- Any cancellation fee on your current fixed contract
There is no universal saving figure. Run a comparison with your own consumption and put the result next to your current annual cost.
Fixed Contracts
Fix the supply rate per kWh and per m³ for a defined period; Vattenfall, Essent and UnitedConsumers, for example, offer one-year and three-year fixed contracts. The supplier may not simply raise the supply rates during the term, but it may pass on increases in taxes and grid operator costs.
Pros:
- Budget predictability
- Protection against rising supply rates during the term
Cons:
- You do not benefit if market prices fall during the term
- A cancellation fee applies if you end the contract before the end date, also when you move house
- A longer fixed term means a longer period in which the market can move away from your rate
Variable Contracts
The supplier can change the rates under the terms of the contract and must announce new rates at least one month in advance.
Pros:
- No cancellation fee
- Rates can come down when the supplier lowers them
- You can end the contract with a notice period of at most one month
Cons:
- Rates can go up during the contract
- Harder to budget
A Sensible Default
A fixed contract of one year, reviewed at every end date, is a common middle route. It:
- Gives budget certainty for the year
- Avoids a multi-year commitment if you are unsure how long you will stay
- Makes you review your contract every year
- Lets you compare welcome offers at each end date
The Switching Process: Step by Step
Step 1: Find Your Annual Consumption
Look at your most recent annual energy statement (jaarafrekening) or log into your current supplier’s portal or app. You need:
- Annual electricity consumption in kWh (for reference: Milieu Centraal gives a national average of 2,430 kWh per household)
- Annual gas consumption in m³ (Milieu Centraal’s national average: 1,040 m³)
- Whether you have solar panels and how much you feed back into the grid
If you do not have a year of data yet, for example because you just moved in, use an estimate. Suppliers such as Vattenfall help you make an estimate during sign-up, and Milieu Centraal publishes averages per household type.
Step 2: Check Your Current Contract
Before you switch, check:
- Contract end date (einddatum)
- Variable or fixed?
- Notice period (opzegtermijn): this is in your contract and is at most one month
- Cancellation fee for early termination (fixed contracts only)
If you are inside a fixed contract and the cancellation fee exceeds the saving from switching, wait until the end date. Your supplier must tell you the fee on request, and that calculation is valid for two months. Set a calendar reminder for two months before the end date to start comparing.
Step 3: Compare Tariffs
Enter your postcode, house number, consumption and preferences (green or grey, fixed or variable, contract length) in a comparison tool or on the suppliers’ own websites. You get a quote with the annual cost based on your consumption.
Also check the suppliers’ own websites, and compare the offer you are given on the day you switch.
Things to verify:
- Is the price per kWh and m³ stated including energy tax and VAT, or excluding?
- What is the fixed supply charge (vaste leveringskosten)?
- What are the conditions of the welcome bonus? If you cancel within six months, a supplier may ask you to repay a welcome bonus, but never more than the bonus itself.
- Green electricity: where is it generated? Eneco and UnitedConsumers both state that they supply 100% green electricity generated in the Netherlands.
Step 4: Sign Up for the New Contract
Once you have chosen, sign up with the new supplier.
You will need:
- Identification and contact details
- IBAN for direct debit (incasso)
- Annual consumption, or an estimate
- Meter readings for the start of supply, if asked
The new supplier arranges the switch and cancels your old contract. UnitedConsumers, for example, writes that it cancels your old energy contract for you and does not reimburse a cancellation fee from your old supplier. After signing up you have 14 days to change your mind (bedenktijd); ACM ConsuWijzer notes that the new supplier must tell you about it.
Step 5: Final Bill from Old Supplier
Your old supplier sends the final bill (eindafrekening) within six weeks, including any cancellation fee. It settles your final meter readings against the monthly instalments you paid. If you paid more than you used, you get money back; if you paid less, you pay the difference.
Check this bill carefully, especially the meter readings on the switch date.
Vattenfall, Eneco, Essent: Which to Pick
These three suppliers each have a different profile.
Vattenfall
- Vattenfall is a Swedish energy company; in the Netherlands it operated under the name Nuon until 2019
- Household contracts on vattenfall.nl: fixed for one or three years, variable for an indefinite term, TijdPrijs (a one-year contract with lower electricity rates during off-peak hours) and dynamic (FlexPrijs), where gas prices change daily and electricity prices hourly; the dynamic contract requires a smart meter
- The Vattenfall Energy app can be switched to English; Vattenfall says the app is partly translated into English at the moment
The practical reason to shortlist Vattenfall at a switch moment is that contract range: fixed, variable, TijdPrijs and dynamic contracts are all available from one supplier. Compare the direct offer against a comparison-site result on the day you switch.

Eneco
Eneco states that it supplies 100% green electricity, generated by wind and sun in the Netherlands, and offers several electricity and gas contracts. If green electricity generated in the Netherlands matters to you, put Eneco’s current contracts on your shortlist and compare the total annual cost.
Essent
- Part of the German energy group E.ON since June 2020
- Offers three contract types: fixed (one or three years), variable and dynamic, with dynamic prices changing per day or per hour
Worth a quote at your moment of switching alongside Vattenfall and Eneco. Essent’s current welcome offers change over time, so compare on the day you switch.

UnitedConsumers: an energy supplier with a savings credit
UnitedConsumers offers 100% green electricity from the Netherlands on three structures: fixed for three years, fixed for one year, or variable with no fixed term. The discount is paid into a “bespaartegoed”, a savings credit: €150 on the three-year contract, €50 on the one-year contract, and 20% off the net kWh rate (excluding energy tax) on the variable contract. Tariffs appear after you enter your postcode and house number (unitedconsumers.com/energie, checked 30 September 2026).
Two points to weigh. A discount held as credit is not the same as a lower kWh rate, so put the all-in tariff next to your current one before you weigh the bonus. And the energy pages are in Dutch, so use a browser translator if needed.
Other Providers
Greenchoice, Vrienden van Energie and Pure Energie also appear on Dutch comparisons. Check each supplier’s own website for its contract types, the origin of its electricity and its current rates.
Common Switching Mistakes
Mistake 1: Switching Inside a Fixed Contract Without Doing the Math
A cancellation fee can cancel out your saving. Check your contract end date and ask your supplier for the fee before switching. If the end date is close, time the new contract to start when the old one ends.
Mistake 2: Comparing Welcome Bonuses Without Looking at What Comes Next
A welcome bonus makes the first year cheaper, but check what happens when the contract ends: the new rates, and whether the contract continues as a variable contract. Set a calendar reminder for 60 days before the contract ends to compare again. Note too that a supplier may ask you to repay a welcome bonus if you cancel within six months.
Mistake 3: Choosing Variable Without Accepting the Price Risk
With a variable contract the supplier can change the rates under the contract terms, with at least one month’s notice. If a sudden rise would strain your budget, a fixed contract gives more certainty.
Mistake 4: Forgetting to Read the Final Bill
Take photos of your meters on the switch date and compare them with the eindafrekening when it arrives. If you disagree with the bill, contact the supplier first; ACM ConsuWijzer explains the next steps.
Mistake 5: Not Arranging Energy When You Move
When you move, check with your supplier whether your contract can move with you to the new address, and pass on the move in good time. Ending a fixed contract early because you move can still cost a cancellation fee.
Saving Beyond Switching
Switching changes your rates; your consumption decides the rest of the bill.
Reduce Gas Use
Milieu Centraal gives these examples for a moderately insulated corner house from 1970, at a gas price of €1.37 per m³:
- Setting the thermostat to 19°C when you are at home: about €170 a year
- Turning off the heating in rooms you are not in, and on the bedroom floor: about €80 a year
- Setting the thermostat to 15°C at night: about €60 a year
Reduce Electricity Use
- LED lighting: according to Milieu Centraal an LED lamp uses 85% less electricity than a halogen lamp and 90% less than an incandescent lamp
- Switch off devices on standby
- Choose energy-efficient appliances when replacing
- Solar panels: the salderingsregeling (net metering) ends on 1 January 2027; see our guide on net metering ending in 2027
Use Less During Peak Hours
With a dynamic contract your electricity price changes per hour, and with a time-of-use contract such as Vattenfall’s TijdPrijs you pay less during off-peak hours. A dynamic contract needs a smart meter; ask the supplier what a time-of-use contract requires. Whether it pays off depends on how much of your use you can move to cheaper hours.
What Energy Looks Like in Your First Month in NL
When you move into a home, check straight away who supplies the energy at the address and arrange a contract in your own name from the move-in date, unless energy is included in your rent.
Order of operations for new arrivals:
- Check your rental contract: do you arrange energy yourself, or is it included?
- Open a Dutch bank account or check that your supplier accepts your account for direct debit
- Take photos of your meters on the day you move in
- Arrange a contract from the move-in date, noting the supplier, type and end date
- Once you know your real consumption, compare again
For full first-month logistics, our first 30 days in NL checklist covers the broader sequence.
Internet, Mobile and Energy
- Energy: compare suppliers as described above
- Internet: see our internet providers guide
- Mobile: see our SIM-only plans guide
Comparing each service separately takes a little more admin; Budget Thuis offers energy, internet and mobile from one provider. Compare both routes on total cost.
When to Compare Now
Compare energy contracts now if:
- You are on a variable contract and have not compared in a while
- Your fixed contract ends in the next 2 months
- You moved house recently and have not chosen a contract yourself
- You have not compared tariffs in over 12 months
When to Wait
- You are within a fixed contract with a high cancellation fee and the end date is still far away
- The saving is small compared with the effort and any cancellation fee
- You are about to move house (arrange energy for the new address instead)
Final Thought
Energy is one of those Dutch admin items that rewards a small amount of attention every year. Know your contract end date, know your consumption, and compare on total annual cost rather than on a headline rate or a bonus.
Set a recurring calendar reminder, “Compare energy contract”, two months before your contract end date.

Frequently Asked Questions
How often should I switch energy supplier in the Netherlands?
Review the contract before its end date and whenever your consumption or tariff changes materially. Compare total annual cost, contract length and any cancellation charge; switching on a fixed calendar schedule does not guarantee a saving.
Do I have to pay an exit fee if I switch energy supplier early?
Only if you have a fixed-term contract, the term has not ended yet, and both are stated in your agreement. Variable and dynamic contracts carry no cancellation fee. For fixed contracts concluded from 1 June 2023, the fee reflects the supplier's loss: your remaining expected consumption multiplied by the difference between your current rate and the rate for a comparable new contract. The supplier must tell you the amount on request, and that calculation stays valid for 2 months.
Is a fixed or variable energy contract better for expats in 2026?
It depends on contract length, risk tolerance, planned stay and the live total cost. Fixed contracts give price certainty for the supply rates, but a fee applies if you end them early, also when you move house; increases in taxes and grid costs can still be passed on. Variable contracts can change under their terms, with at least one month's notice, and can be ended without a fee. Read the price-change and cancellation conditions before choosing.
What documents do I need to switch energy supplier in the Netherlands?
Providers commonly ask for the supply address, meter or EAN details, expected annual consumption, identification and payment information. Requirements and switching steps differ, so follow the new provider's checklist and confirm how the old contract will end.
How much can I realistically save by switching energy supplier in the Netherlands?
There is no reliable universal saving. Enter your own annual consumption and compare total annual cost, fixed charges, unit rates, bonuses and any cancellation fee. Treat comparison output as a quote snapshot, not a guaranteed yearly saving.
Can I switch energy supplier as a renter?
If your rental contract says you arrange and pay for energy yourself, you choose the supplier and can switch under the terms of your energy contract. If your landlord includes energy in the rent, the landlord arranges the supply, so check your rental contract first. If you have a fixed-term energy contract and leave before its end date, a cancellation fee can apply, also when you cancel because you are moving; a variable contract can be ended without a fee.
