The entry into force of Royal Decree 88/2026, of February 11, represents much more than a regulatory update for the electricity sector: it introduces a structural change in the way in which marketers must manage the relationship with their customers. From now on, it is not enough to comply; it is essential to demonstrate compliance. This new paradigm drives companies towards a digitalization focused on evidence, traceability and legal certainty.

A new regulatory framework with immediate (and progressive) impact
The regulation came into force on February 12, 2026, the same day of its publication in the BOE. However, its application is partially progressive. Some aspects -especially those linked to key supply and contracting processes- take effect on June 12, 2026, marking a clear adaptation schedule for the sector.
This staggered approach does not reduce their impact: on the contrary, it provides a limited window for marketers to review and strengthen their processes before the new requirements become fully enforceable.
From formal compliance to proof of compliance
The real change introduced by RD 88/2026 is conceptual. The regulator raises the standard: it is no longer sufficient for processes to be defined or executed correctly, but they must be auditable, verifiable and demonstrable at any time.
This directly affects all critical points of the customer lifecycle:
- Contracting: obligation to provide clear and prior information through documents separate from the contract.
- Telephone contracting: need to keep complete recordings and evidence of consent.
- Contractual modifications and price revisions: mandatory, individualized and with minimum advance notice.
- Claims and disputes: requirement to reconstruct the complete history of the interaction.
| Process | Requirement under Royal Decree 88/2026 | Required Evidence | Recommended Solution |
|---|---|---|---|
| Procurement | Preliminary informational documentation in documents separate from the contract | Verify delivery, content, and timing of pre-contractual documentation | Certified email |
| Telephone Enrollment | Retain complete recordings and evidence of consent | Time-stamped recording + proof of consent | Certified communications + GDPR consent management |
| Changes / Price Revision | Mandatory, individualized notification, with a minimum advance notice period | Proof of notification with exact date, channel, and content | Certified notifications: SMS / email / WhatsApp |
| Complaints | Reconstruct the complete history of the interaction | Certified archiving of all communications in the file | Archiving + QPRES custody if there is a signature |
| Changing Energy Providers | Process begins within 24 hours; completion within 10 business days at most | Each step is logged with a verifiable timestamp | CCM platform with process traceability |
In this context, the risk no longer lies solely in noncompliance, but in being unable to demonstrate compliance during an inspection or in response to a complaint. While it can be said that the cross-cutting standards of the SAC Act established the general operational framework for customer service in large companies, this new regulatory framework implements and tightens those criteria for the energy sector.
Operational Impact of Royal Decree 88/2026: More Demanding Processes, Tighter Deadlines
The operational impact of Royal Decree 88/2026 focuses on two areas: reducing the timeframes for critical processes and requiring that each step be documented with traceable evidence that is available in the event of any inspection or complaint.
The new regulation also introduces pressure on timing and operations. For example:
- The incoming marketer must initiate the changeover within 24 hours on a business day.
- The customer has the right to complete the exchange within a maximum of 10 working days.
These requirements demand agile execution, but also impeccable document management, where every step is recorded and available.
The consequence is clear: digitization can no longer be limited to optimizing internal processes; it must guarantee the integrity, traceability and availability of evidence.
Compliance-driven digitization: a new strategic priority
This new regulatory environment drives a natural evolution in the sector:
From a process-oriented digitization
→ focused on operational efficiency
Toa compliance-oriented digitization
→ focused on evidence, legal certainty and trust
This is where technologies such as electronic signatures, time-stamping, communication certification and evidence custody become key elements, not only to comply with regulations, but also to reduce risks and strengthen the relationship with the client.
Beyond obligation: an opportunity to lead
While RD 88/2026 poses significant challenges, it also opens up a clear opportunity: to differentiate through transparency, trust and excellence in customer management.
Marketers that take a proactive approach will not only minimize regulatory risks, but will be able to transform compliance into a tangible competitive advantage.

Frequently Asked Questions
What is Royal Decree 88/2026, and who does it affect?
Royal Decree 88/2026, dated February 11, modifies the relationship between electricity retailers and their customers. It took effect on February 12, 2026, and its most significant impacts on contracting and supply processes will take effect on June 12, 2026. It affects all electricity retailers in the Spanish market and their customer service and communications providers.
What deadlines does Royal Decree 88/2026 establish for switching electricity suppliers?
The incoming supplier must initiate the process within 24 hours on a business day following the request. The entire process must be completed within 10 business days. Any delay must be justified with objective evidence for each step of the process.
What is the difference between complying with Royal Decree 88/2026 and being able to prove it?
Compliance involves correctly executing processes: sending pre-contractual documentation, recording communications, and communicating rate changes. Being able to demonstrate compliance means that this execution is supported by objective, verifiable, and accessible evidence: certified communications, recordings with a qualified seal, and a traceable archive. Royal Decree 88/2026 raises the standard to the second level.
Which processes require certified evidence under Royal Decree 88/2026?
The most critical elements are: (1) provision of pre-contractual documentation, (2) recordings of telephone contract negotiations with evidence of consent, (3) communications regarding contract amendments or price revisions, (4) individualized notifications, and (5) archiving of the claims history. In all cases, the evidence must be auditable and verifiable by the CNMC.
What is “compliance-oriented digitization” in the electric power sector?
Process-oriented digitization aims for operational efficiency. Compliance-oriented digitization adds the requirement that each process leave traceable evidence with legal validity. Royal Decree 88/2026 mandates this second level: electronic signatures, time stamps, certified communications, and evidence preservation go from being optional to essential for regulatory compliance.
