Contractor companies with the Public Administration that have contracts with price revision clauses now have the official indices for the third quarter of 2025 (July-September). The Order HAC/618/2026, published on June 19, 2026, establishes the reference values of mandatory application for calculating any price revision in public sector contracts.
The delay in publication compared to the reference quarter is a common pattern in this type of orders and does not invalidate its retroactive application. This means that contractors can—and must—use them to request adjustments for the period already elapsed.
What does this regulation establish?
Order HAC/618/2026 publishes the official price revision indices applicable to public sector contracts for the third quarter of 2025, in compliance with article 103 of the Law 9/2017 on Public Sector Contracts (LCSP). These indices are mandatory: they cannot be replaced by other indicators or by agreement between the parties.
The order covers four major blocks of indices:
| Block | What it includes | Contracts it applies to |
|---|---|---|
| Labor | Labor cost indices | Works, services and supplies contracts with labor component |
| General materials | Aluminum, cement, energy, steel, copper and other materials | General works and supplies contracts |
| Specific materials for weapons and equipment | Indices of specific materials for weapons and equipment manufacturing | Supply contracts for military weapons and equipment |
| Components of regular passenger road transport | Indices of cost components for regular passenger transport | Regular passenger road transport contracts |
Each index reflects the variation in costs experienced in the July-September 2025 period compared to the contract's reference period. The contractor applies the revision formula agreed in the specifications, replacing the variables with the values published in this order.
Economic and operational impact
The direct impact of this order is economic and immediate: it allows contractors to recover—or adjust—part of the actual cost incurred during Q3 2025 in materials, energy and labor.
The materials with the highest historical volatility in public works contracts are precisely those covered by this order: aluminum, cement, energy, steel and copper. In periods of high inflation or tension in commodity markets, price revision can mean significant differences in contract margins.
From an operational perspective, the publication of these indices activates a management obligation: the contractor must review its active contracts, identify which ones have a revision clause, calculate the adjustment with the published indices, and submit the request to the corresponding Administration. Failure to do so within the deadline may result in loss of the right to revision.
For regular passenger road transport contracts, cost component indices allow adjustment of the compensation received by the concession company, particularly relevant in a sector with high exposure to fuel prices and labor costs.
Who does it affect?
- Construction companies and civil works firms with public works contracts that include price revision formulas based on material indices (aluminum, cement, steel, copper, energy).
- Supply companies of goods and equipment to the Public Administration with contracts that provide for price revision.
- Manufacturers and suppliers of weapons and equipment with contracts with the Ministry of Defense or other public security agencies.
- Regular passenger road transport operators with concessions or public service contracts.
- Advisors, controllers and CFOs of any of the above companies, responsible for managing the economic settlement of public contracts.
Practical example
Imagine a construction company with a public works contract signed in 2023, with a price revision formula that includes a steel component and an energy component. The specifications establish that the revision will be calculated quarterly by applying the official indices published by the Ministry of Finance.
With the publication of Order HAC/618/2026, this company now has the values for Q3 2025 for both components. The process is as follows:
- Locate in the order the steel and energy indices corresponding to the third quarter of 2025.
- Apply the revision formula agreed in the specifications, replacing the variables with the published indices.
- Calculate the resulting revision amount and document it.
- Submit the price revision request to the contracting Administration, attaching the justified calculation.
Given that the order is published with a delay compared to Q3 2025, the company can submit the request now with full legal validity. The specific amount will depend on the values of the indices published in the order and the weight of each component in the formula of the specific contract.
What should companies do now?
- Review the portfolio of active public contracts and identify which ones include price revision clauses in accordance with article 103 of the LCSP.
- Locate the revision formula agreed in each specifications document and verify which indices published in Order HAC/618/2026 are applicable.
- Calculate the revision amount for the third quarter of 2025 (July-September) using the official published indices: labor, general materials (aluminum, cement, energy, steel, copper), weapons materials or transport components, as applicable.
- Prepare and submit the revision request to the contracting Administration, with the justified calculation and reference to Order HAC/618/2026.
- Control internal deadlines of each contract to avoid losing the right to revision due to prescription or failure to meet contractual deadlines.
- Alert the contract management team to apply this same process in pending settlement quarters and be prepared for Q4 2025 indices when published.
Frequently asked questions
What materials does Order HAC/618/2026 cover for Q3 2025 price revision?
The order covers four blocks: labor cost indices, general materials indices (which explicitly include aluminum, cement, energy, steel and copper), specific materials indices for weapons and equipment supply, and regular passenger road transport component indices.
Is it mandatory to use these indices or can I agree on others with the Administration?
They are mandatory for all public contracts that have price revision clauses in accordance with article 103 of Law 9/2017 on Public Sector Contracts. They cannot be replaced by other indicators or by agreement between the parties.
Does the delay in publication prevent me from claiming Q3 2025 revision?
No. Publication with a delay compared to the reference quarter is common in this type of orders and does not invalidate its retroactive application. Contractors can submit the revision request now, once the indices are published, with full legal validity.
What happens if I don't request price revision using these indices?
If you do not submit the revision request within the deadlines established in your contract, you may lose the right to claim the economic adjustment corresponding to Q3 2025. The regulation does not apply ex officio: it is the contractor who must initiate the process.
Where can I consult the specific values of the published indices?
The specific values of each index are published in the full text of Order HAC/618/2026, available in the BOE with reference BOE-A-2026-13351. You can consult it directly in the official source linked at the end of this article.
