Analysts from Gaslicht.com and Vattenfall provide their insights on the coming winter months. After a relatively calm summer, energy market experts expect gas prices to rise slightly in Q3 2026 due to increased demand from Asia and lower LNG production. For households, this makes choosing the right energy contract this autumn more important than ever.
For consumers with a variable contract, it is advisable to switch to a fixed price now. Current tariffs are still well below the peak prices of 2022. Experts recommend considering a 1-year fixed contract as a buffer against price fluctuations.
What drives energy prices in Q3 2026?
The Dutch energy price is directly linked to the international gas and electricity market. Several factors determine where tariffs head over the coming quarter:
- Demand from Asia: Asian countries buy extra LNG in the summer to replenish their stocks for winter. This competition for the same shipments pushes up the European gas price.
- LNG supply: Since 2022, Europe has been heavily dependent on liquefied natural gas. Maintenance at export terminals or production outages can temporarily reduce supply.
- Filled gas storage: The fuller Europe’s gas buffers are at the end of summer, the more stable the price going into winter. The fill level is therefore an important indicator.
- Weather forecast: An early cold snap increases heating demand and drives up the price. A mild winter does the opposite.
- CO2 price and network tariffs: Alongside the bare energy price, network management costs and taxes are rising too. These account for an ever-larger share of your final bill.
Fixed, variable or dynamic contract: which suits you?
The biggest choice you make is the type of contract. Each type has its own pros and cons:
- Fixed contract: Your tariff is fixed for 1, 2 or 3 years. Maximum certainty and protection against price increases, but you don’t benefit if the market falls. Ideal if you want peace of mind and predictability.
- Variable contract: The tariff moves with the market and is usually adjusted twice a year. Flexible, but you bear the risk of sudden price spikes.
- Dynamic contract: The price changes every hour based on the wholesale market. Attractive if you can shift your consumption to cheap hours (for example with solar panels, a home battery or an electric car), but it requires active management.
For most households seeking certainty this winter, a 1-year fixed contract is currently the safest choice. Generate your own electricity or charge an EV? Then a dynamic contract may actually work out cheaper.
Have a dynamic contract? With a home battery from Zendure (SolarFlow Hyper 2000) you can store electricity during the cheapest hours and use it when prices peak.
5 ways to lower your energy bill this winter
- Compare and switch: Switching is free and can save you hundreds of euros a year. Many suppliers also give new customers a welcome discount.
- Turn the thermostat down one degree: One degree less quickly saves around 6% on your gas consumption.
- Insulate where you can: Draught strips, radiator foil and good curtains keep the heat inside and pay for themselves quickly.
- Shift your consumption: With a dynamic contract you run the washing machine and dishwasher during the cheapest hours.
- Gain insight into your usage: A smart energy meter shows in real time where your electricity goes, so you can save in a targeted way.
What should you do now?
Do you currently have a variable contract and don’t want to be caught out by a cold winter? Then compare the fixed tariffs today. If they are in line with or below your current variable tariff, you lock in your price for the coming year. If you generate your own electricity or are flexible with your consumption, consider a dynamic contract.

Frequently asked questions
Is it smart to take out a fixed contract now?
If current fixed tariffs are below or around your variable tariff, a fixed contract protects you against the expected price rise in Q3 2026. For those who want certainty, that is currently the safest choice.
What is the difference between a dynamic and a variable contract?
With a variable contract the price changes a few times a year; with a dynamic contract it changes every hour based on the wholesale market. Dynamic is cheaper if you can manage your consumption.
Does switching energy supplier cost money?
No, switching is free and your new supplier handles the cancellation. If you are in a fixed contract, do watch out for any early termination fee.
