| Publication | 14 July 2026 |
| Entry into force | 1 July 2026 |

| Body | Council of the EU — European Atomic Energy Community (Euratom) |
Companies in the nuclear and energy sector with a presence in Gibraltar have, from 1 July 2026, a new regulatory framework that regulates their obligations towards Euratom. The Council Decision (Euratom) 2026/1564, published in the EU Official Journal on 14 July 2026, formally approves the agreement between the EU/Euratom and the United Kingdom specifically referring to Gibraltar in the field of atomic energy.
This agreement is part of the broader post-Brexit framework of relations. Gibraltar left the EU together with the United Kingdom, but its geographical and economic situation makes differentiated treatment necessary. The European Commission acts here on behalf of the European Atomic Energy Community (Euratom), which has direct consequences for any operator handling nuclear materials or providing energy services linked to that territory.
What does this regulation establish?
The agreement defines the regime applicable to Gibraltar in three specific areas of atomic regulation:
- Nuclear safety standards: It establishes which Euratom safety standards are applicable in Gibraltar and how they are articulated with United Kingdom regulations.
- Safeguards on nuclear materials: The controls and supervision mechanisms applicable to the use, transfer and storage of nuclear materials in the Gibraltar territory are established.
- Cooperation in atomic matters: The framework for collaboration between EU/Euratom authorities and the United Kingdom for the management of nuclear affairs in Gibraltar is regulated.
The European Commission acts as a signatory party on behalf of Euratom, which means that the obligations arising from this agreement are binding for the affected operators from the date of entry into force.
| Regulated area | Agreement content |
|---|---|
| Nuclear safety | Euratom safety standards applicable in Gibraltar |
| Safeguards | Controls on use, transfer and storage of nuclear materials |
| Atomic cooperation | Framework for collaboration EU/Euratom — United Kingdom for nuclear affairs in Gibraltar |
| Supervision | Compliance obligations arising from the relationship with Euratom |
Economic and operational impact
The impact is not of a direct fiscal nature (there are no fees or amounts established in this decision), but rather operational and regulatory compliance. Affected companies should assess the following effects:
- Regulatory adaptation costs: Review and update internal procedures for managing nuclear materials to align with the new Euratom framework applicable in Gibraltar.
- Audits and controls: The safeguards provided for in the agreement mean that operators may be subject to inspections and verifications by the competent Euratom authorities.
- Legal certainty: The agreement provides certainty about the applicable regime, eliminating the post-Brexit ambiguity that existed for nuclear operations in Gibraltar. This is an advantage for medium-term planning.
- Contractual relationships: Contracts with suppliers, customers or partners linked to nuclear activities in Gibraltar must be reviewed to verify their alignment with the new framework.
Who does it affect?
- Energy sector companies with facilities or operational activity in Gibraltar.
- Nuclear sector operators managing atomic materials with origin, destination or transit through Gibraltar.
- Entities linked to the United Kingdom operating under the Euratom umbrella in activities related to atomic energy.
- Legal advisors and regulatory compliance professionals managing contracts or licenses in the nuclear field for clients with a presence in Gibraltar.
- CFOs and operations directors of business groups with subsidiaries or activity in Gibraltar who must report on nuclear regulatory compliance.
Practical example
A Spanish energy sector company operating a radioactive waste management facility with logistical connection to Gibraltar must, from 1 July 2026, verify that its nuclear material control procedures in that territory comply with the safeguards established in the Euratom-United Kingdom agreement.
Before this agreement, the post-Brexit situation created uncertainty about which Euratom rules were enforceable in Gibraltar. With Decision 2026/1564 in force, that company has a clear framework: Euratom nuclear safety standards and safeguard controls apply with the specific regime agreed. If the company has not updated its internal protocols to reflect this new framework, it is exposed to non-compliance detectable in a Euratom inspection.
What should companies do now?
- Identify if you have nuclear or energy activity linked to Gibraltar: Review whether any of your operations, contracts or facilities involve nuclear materials with connection to that territory.
- Review internal safeguard procedures: Check that controls on use, transfer and storage of nuclear materials in Gibraltar are aligned with the new Euratom framework.
- Update contracts and agreements with third parties: Review contracts with partners, suppliers or customers linked to nuclear activities in Gibraltar to ensure their compliance with the agreement.
- Consult with a specialist advisor in nuclear law and Euratom regulation: The technical and legal complexity of this field requires specialized advice to determine the exact scope of obligations applicable to your specific case.
- Prepare documentation for possible inspections: Safeguards involve controls by Euratom. Having compliance documentation in order reduces the risk in any verification.
Frequently asked questions
When does the Euratom agreement on Gibraltar enter into force?
The agreement entered into force on 1 July 2026, although the Council Decision formally approving it was published in the EU Official Journal on 14 July 2026.
What exactly does the Euratom-United Kingdom agreement on Gibraltar regulate?
The agreement regulates three areas: the nuclear safety standards applicable in Gibraltar, the safeguards on nuclear materials (controls on use, transfer and storage) and the framework for atomic cooperation between the EU/Euratom and the United Kingdom for that territory.
Which companies does this agreement on atomic energy in Gibraltar affect?
It affects companies and entities in the nuclear or energy sector with activity in Gibraltar or linked to the United Kingdom in atomic matters: operators managing nuclear materials, energy companies with facilities in Gibraltar and regulatory compliance advisors in that field.
What specific obligations does the agreement impose on operators?
Operators must comply with Euratom nuclear safety standards applicable in Gibraltar and be subject to the safeguard controls established in the agreement. This includes the possibility of inspections and verifications by the competent Euratom authorities on the use and management of nuclear materials in that territory.
Why does Gibraltar need a specific Euratom agreement after Brexit?
Gibraltar left the EU together with the United Kingdom with Brexit, falling outside the Euratom regulatory framework. Its particular situation required a specific agreement —different from the general EU-United Kingdom framework— to define which nuclear safety standards and atomic safeguards apply in that territory and how they are articulated with United Kingdom regulations.
