Independently researched

This way, you’ll know which supplier really scores well

The energy market is constantly changing. Rates change weekly, suppliers adjust their offers and terms, and a high review score doesn’t tell the whole story. Figuring out for yourself which supplier is consistently affordable, customer-friendly, or suitable for solar panels takes a lot of time. That’s why we do it for you: with our annual, independent study.

We use our own price data from the energy comparison tool, analyze thousands of customer reviews, and critically evaluate suppliers based on accessibility, service, and terms and conditions. The top-scoring suppliers receive the Best Choice Award every year.

Which energy supplier is best for solar panels?

In 2026, UnitedConsumers is the best energy supplier for households with solar panels based on the lowest price, with a score of 9.5. Budget Thuis comes in second, and Vandebron finishes third. This price calculation includes feed-in costs and feed-in tariffs.

About the Study

Every year, the Keuze.nl energy team investigates which energy suppliers rank best in terms of price, solar panels, and customer satisfaction.

For 2026, we used, among other things, price data from our energy comparison tool, customer reviews, and information about customer service. The study was reviewed by energy expert Geert Wirken.

Frequently Asked Questions

How does Keuze.nl choose the best energy supplier?

 

For this study, we use our own price data from our energy comparison tool, examine multiple consumption scenarios, analyze customer reviews, and evaluate suppliers based on service, responsiveness, and terms and conditions. In doing so, we look not only at promises but also at the fine print.

Our price calculations include all costs, including discounts, feed-in costs, and feed-in tariffs. When assessing customer satisfaction, we look beyond just a review score: we also evaluate whether a supplier is easy to reach and provides substantive responses to customers.
 

SectionHow we evaluate this
Suppliers17 suppliers with a fixed-term contract, active in our comparison tool, and holding their own supply license.
PriceWe track weekly which providers are in the top 3 cheapest contracts for low, medium, and high consumption.
Customer SatisfactionRated based on app quality, reviews, responsiveness, quality of responses, and terms and conditions.
Solar PanelsTotal annual price, including feed-in costs and feed-in tariffs. Suppliers with a negative net feed-in tariff were excluded.

Who is the best dynamic energy supplier?

 

Dynamic contracts are not included in this study of the best energy supplier offering a fixed-rate contract. We have made a conscious decision to exclude them because a dynamic contract works differently from a fixed-rate contract.

That’s why we’re evaluating dynamic energy suppliers in a separate study, where we look at factors such as price, customer satisfaction, and suitability for households with solar panels.

Check out the best dynamic energy supplier.

Who is the most reliable supplier?

 

In our energy comparison tool, we only list suppliers we trust. However, we take a particularly critical look at suppliers whose terms and conditions could be disadvantageous to consumers. 

For example:

  • Cashback that turns out to be lower than expected
  • Aggressive sales tactics
  • Unclear terms and conditions
  • Fixed rates that may still change
  • A negative net feed-in tariff for solar panels

Are you unsure about a supplier? Don’t just look at the price—also consider the terms and conditions, reviews, and responsiveness.

Which energy supplier is right for you?

 

That depends on your situation. Based on our research, here is our advice:
 

Your situationBest choiceWhy
You want the lowest priceBudget ThuisConsistently affordable for many households with low to high energy consumption for years.
You have solar panelsUnitedConsumers or Budget ThuisOften a good deal for solar panel owners, despite feed-in costs.
You value customer serviceUnitedConsumers or Pure EnergieHigh scores for personalized service, responsiveness, and customer feedback.

The best energy supplier isn’t the same for everyone. Your choice depends on what matters most to you, such as price, customer service, or sustainability. Your address, energy usage, and solar panels also play a role.
