After years of negotiation, a formal agreement was finally reached in June 2025 between Spain, the United Kingdom, Gibraltar and the European Union. The deal redefines Gibraltar’s position in Europe post-Brexit and introduces major changes to how the border with Spain is managed.
Under the new agreement, Gibraltar will be treated as part of the Schengen zone for mobility purposes, despite not being a member of the EU. In practical terms, this means that passport control for travellers arriving in Gibraltar will take place at its airport and seaport, where Spanish border officials will carry out Schengen checks.
This arrangement removes the need for passport checks at the land border between Gibraltar and La Línea de la Concepción. The checkpoint that once separated the territory from mainland Spain, often associated with traffic bottlenecks, queues and political friction, will no longer function as a hard border for people.
As a result, the land crossing will operate more like an internal EU border, with free and continuous movement. This marks a major shift for the region, particularly for the thousands of workers and service providers who cross into Gibraltar from Spain on a daily basis.
This development is particularly significant for the Campo de Gibraltar, the region of southern Spain bordering the British territory. An estimated 15,000 people cross the border daily, many of whom live in Spain and work in Gibraltar. For them, and for businesses dependent on efficient cross-border movement, the removal of land checks offers greater predictability and less disruption.
The agreement also lays the groundwork for closer alignment between Gibraltar and the EU on issues such as customs and taxation. Gibraltar will begin to harmonise its indirect tax regime with European standards, particularly regarding goods such as tobacco and fuel. This shift is designed to tackle long-standing issues around price differences and smuggling and to promote a more balanced commercial relationship between Gibraltar and its neighbouring regions in Spain.
Crucially, the question of sovereignty remains unchanged. Spain continues to assert its claim to Gibraltar and the UK maintains full control. The agreement instead focuses on practical cooperation, prioritising movement, trade and regional development over political disputes.
The broader aim is to create a shared space of opportunity between Gibraltar and southern Spain, encouraging investment, job creation and improved infrastructure. Commitments have been made on environmental standards, law enforcement, labour rights and education, with new joint mechanisms being introduced to support future collaboration across these areas.
While the long-term implications of the agreement will depend on how it is implemented, the removal of the hard border and the establishment of shared frameworks marks a major breakthrough. For many in the region, it signals a move away from uncertainty and towards a more cooperative and integrated future.
At Move Project, we understand how changes to policy and regulation affect planning, development and construction on the ground. If you operate in the south of Spain or have projects involving Gibraltar, this agreement will likely influence labour, logistics and regional planning frameworks.
