Energy contracts 2026: what energy retailers must change

Key data

Energy retailers have a clear regulatory signal from Brussels on the table: supply contracts must be more transparent and comparable. The Recommendation (EU) 2026/1008 of the European Commission, adopted on 30 April 2026 and published on 8 May, asks that electricity and gas contracts include a standardized summary of their main conditions.

It is not a directive. It does not create immediate obligation. But ignoring it would be a mistake: this type of recommendation is usually the step before binding legislation, and companies that anticipate it will have lower adaptation costs when the mandatory rule arrives.

What does this regulation establish?

The European Commission directs this recommendation to two recipients: the Member States and the energy supply companies. The message is twofold:

• Member States must incorporate these criteria into their national regulation.
• Energy retailers must adapt their contract models and pre-contractual documentation to include a standardized summary of the main contractual conditions.

The stated objective is to improve transparency and facilitate comparison between offers by domestic consumers and small businesses. In practice, this means that the customer must be able to understand at a glance the key points of their contract before signing it, without having to read dozens of pages of small print.

The measure is part of the European package for energy consumer protection, which indicates that it is not an isolated initiative but part of a broader regulatory strategy. This increases the likelihood that it will lead to binding legislation in the short or medium term.

Economic and operational impact

As it is a recommendation, the immediate economic impact is limited. There are no direct penalties for non-compliance today. However, the operational implications for energy retailers are real and should be assessed:

• Review of contract models: Current supply contracts will need to incorporate a standardized summary. This involves legal work and documentation design.
• Adaptation of pre-contractual documentation: The contracting process with domestic and SME customers will need to be updated to include the summary before signing.
• Costs of early compliance: Companies that adapt their processes now will avoid urgent adaptation costs when Spanish transposition arrives, which may impose tight deadlines.
• Reputational and commercial risk: In a competitive energy market, contractual transparency can become a sales argument or a liability if competitors adapt first.

Energy retailers operating in several European markets must also consider that other Member States may transpose the recommendation before Spain, creating temporary regulatory asymmetries.

Who does it affect?

• Electricity retailers that supply domestic consumers or small businesses.
• Natural gas retailers with the same customer segments.
• Domestic consumers as recipients of the highest level of protection and transparency.
• Small businesses with energy supply contracts, which will benefit from more understandable and comparable contracts.
• Legal and compliance departments of energy retailers, which will need to review and update contractual documentation.
• Advisors and consultants in the energy sector who assist companies in reviewing their supply contracts.

Practical example

An electricity retailer operating in the SME market in Spain currently has a 12-page supply contract with conditions scattered across price, duration, early termination penalties and tariff reviews.

With the application of this recommendation, it will need to add at the beginning of the contract a standardized summary that clearly and concisely sets out the main conditions: applicable price, contract duration, renewal conditions, penalties and tariff review mechanism. This summary should allow the customer to compare this offer with that of another retailer without having to read the entire contract.

When Spain transposes the recommendation into its national regulations, this summary will cease to be a best practice and become a legal requirement. Energy retailers that have already implemented it will not need to do anything additional. Those that have not will need to adapt within the timeframe set by the Spanish regulation, with the cost and urgency that this implies.

What should companies do now?

1. Review current supply contracts to identify whether they already include some type of summary of main conditions or whether it would need to be created from scratch.
2. Monitor transposition in Spain of this recommendation, as when it becomes national law it will establish specific compliance timelines and requirements.
3. Prepare a draft standardized summary with the main contractual conditions, anticipating the criteria that the Spanish regulation will likely require: price, duration, renewal, penalties and tariff reviews.
4. Update pre-contractual documentation so that the summary is delivered to the customer before signing, not just as an annex to the contract.
5. Coordinate with the legal and commercial teams to ensure that the summary is understandable for domestic consumers and small businesses, not just for lawyers.
6. Monitor the evolution of the European energy consumer protection package, of which this recommendation is part, to anticipate future binding obligations in the sector.
