From today, 15 July 2026, travellers entering Gibraltar will notice that the British overseas territory has slipped quietly into the Schengen family. The UK-EU Treaty on Gibraltar, negotiated in parallel with the wider Trade and Cooperation Agreement, has come into provisional force and with it Gibraltar’s short-stay visa and customs regime now mirrors that of the Schengen area. British citizens can still visit visa-free for up to 90 days in any 180-day period, but that time will now be counted alongside days spent elsewhere in Schengen. Third-country nationals who previously relied on a UK visa or UK residence status to enter Gibraltar will need to follow standard Schengen visa rules. Practically, inbound passengers arriving at Gibraltar airport will be processed twice: first by Gibraltar officials for entry to the territory and immediately afterwards by Spanish officials carrying out Schengen Entry/Exit System (EES) procedures. Fingerprint and facial biometrics will be taken where required, and passports must have at least three months’ validity beyond the intended date of departure from the Schengen zone. Dual UK-Irish nationals travelling on an Irish passport will be treated as EU citizens and therefore exempt from the 90-day limit and EES registration. For business travellers and global mobility managers, the biggest change concerns the cumulative 90/180-day Schengen calculation. Time spent on short trips to Gibraltar will now reduce the allowance available for meetings in Spain, France or the rest of Schengen. Companies should begin tracking travel days for UK staff in Gibraltar just as they would for any other Schengen destination. Gibraltar’s authorities have confirmed that those wishing to stay longer than 90 days must register with the Department of Immigration and Home Affairs. Customs rules are also shifting. Gibraltar will operate a bespoke customs model designed to keep the land border with Spain friction-free; however, arriving air passengers will, for the first time, be required to declare certain goods on arrival. HM Customs Gibraltar advises corporates relocating staff to review new allowances for personal effects and high-value equipment. The Borders and Coastguard Agency has published further guidance and will issue real-time updates on border wait times during the bedding-in period.
