From 15 July 2026, travellers to Gibraltar—including those arriving on flights from the UK—face a new dual-border regime after the provisional application of the UK-EU Agreement on Gibraltar. Updated Foreign Office travel advice confirms that short-stay visitors will be processed under Schengen rules, with Spanish officers conducting Entry/Exit System (EES) checks alongside Gibraltar authorities at the airport. British citizens will be able to stay up to 90 days in any 180-day period, and that time will now count towards their overall Schengen allowance. Customs rules will also change, creating a bespoke model intended to remove goods checks on the land border with Spain. Officials say the arrangement should eliminate the notorious frontier queues that have long frustrated tourists and cross-border workers, although enhanced data capture may lengthen processing for first-time arrivals. For UK employers the shift is significant: staff on short business trips to Gibraltar must start tracking Schengen-day usage to avoid inadvertent overstays that could jeopardise future EU travel. HR teams should update travel-policy text and booking tools to flag that Gibraltar time now erodes the same allowance as, say, Paris or Frankfurt. The treaty stops short of granting Gibraltar full Schengen membership, and longer-term assignments (over 90 days) will still require local registration. Spain retains responsibility for external-border policing, while Gibraltar keeps internal immigration competence—a hybrid that will be tested during the busy summer season. Airlines are already advising customers to allow extra time at Heathrow and Manchester for exit checks that feed Gibraltar’s new passenger-locator system. Mobility advisers should ensure passports have at least three months’ validity beyond departure, mirroring mainstream Schengen rules.
