Choosing a Czech energy supplier? New tool looks beyond the cheapest price

Finding the cheapest electricity or gas tariff in Czechia is relatively easy. Working out whether it is actually the best deal can be considerably more complicated.

A new comparison system unveiled in Prague this week aims to make that decision easier by evaluating energy offers not only on price, but also supplier stability, customer service and other contract conditions that can ultimately affect how much households pay.

The Energy Compass (Energetický kompas), developed by Savings Tech Lab and the Prague University of Economics and Business's Institute of Sustainable Finance, brings those factors together into a single score.

The tool could be particularly useful for consumers faced with a long list of seemingly similar electricity or gas offers, where the cheapest advertised rate may come with less favorable conditions elsewhere in the contract.

Price remains an obvious starting point when comparing electricity and gas contracts, but the creators of the Energy Compass warn against using it as the only criterion.

A cheaper tariff could be accompanied by a high penalty for leaving a fixed-term contract early, less favorable contractual conditions or poor customer service when something goes wrong.

Supplier stability is another consideration, particularly given the upheaval on the Czech energy market in recent years. The Energy Compass is therefore designed to assess three broad areas: the energy product itself, the level of risk associated with its supplier and the quality of customer service.

Its methodology draws partly on consumer surveys conducted in 2023, 2024 and 2026. In those surveys, 73 percent of respondents said an independent score combining price, supplier stability and customer service would help them choose an energy provider.

The developers also looked at approaches used elsewhere in Europe, including customer-service assessments in Britain, transparency standards for comparison tools in Germany and independent price comparisons in Belgium.

For consumers, the aim is to turn a complicated comparison into a more straightforward assessment rather than requiring them to evaluate every condition individually.

There is one important catch for anyone hoping to use the Energy Compass immediately: its first results are currently anonymized. Scores identifying individual suppliers and offers are expected to be published in October.

In the meantime, Czechia's Energy Regulatory Office (ERÚ) already operates its own independent comparison tool for electricity and gas offers. ERÚ chairman Jan Šefránek welcomed the broader approach of the new system, while similarly cautioning consumers against choosing a supplier solely on the basis of price.

"The reputation of the supplier and other aspects are also important, depending on the individual preferences of each consumer," he said.

When comparing offers, households should therefore look at the full price they will pay, whether the rate is fixed or variable, the length of the contract, conditions for renewal and termination, and any penalties for leaving early.

Customer-service accessibility and the supplier's reputation can also become important if billing problems, contract changes or other issues arise.

For foreign residents, understanding those conditions may be especially useful before signing a Czech-language energy contract. A low advertised rate can be attractive, but the overall terms determine whether switching suppliers actually saves money over the life of the agreement.

The Energy Compass's first supplier-specific results are due in October, adding another resource for households looking to compare their options before signing or renewing an electricity or gas contract.
